6003-006

Driving on slopes

Driving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it.

Proceed as follows:

???Remove obstacles such as stones, branches, etc.

???Mow upwards and downwards, not sideways.

???Do not use the machine on ground that slopes more than 15??.

???Avoid starting or stopping on a slope. If the tyres start to slip, stop the blades and drive slowly down the slope.

???Always drive smoothly and slowly on slopes.

???Do not make any sudden changes in speed or direction.

???Avoid unnecessary turns on slopes, if necessary, turn slowly and gradually downwards if possible.

???Watch out for and avoid driving over furrows, holes and bumps. It is easier for the machine to overturn on uneven ground. Tall grass can hide obstacles.

???Drive slowly. Do not turn the wheel sharply. The machine engine-brakes better in low gear.

???Take extra care if any attachments are fitted that can change the stability of the machine.

???Do not mow too close to edges, ditches or banks. The machine can suddenly overturn if one wheel comes over the edge of a steep slope or a ditch, or if an edge gives way.

???Do not mow wet grass. It is slippery, and tyres can lose their grip so that the machine skids.

???Do not try to stabilize the machine by putting your foot on the ground.

???When cleaning the chassis the machine must never be driven close to an edge or ditch.

???Follow the manufacturer???s recommendations regarding wheel weights or counterbalance weights to increase stability.

Mow upwards and downwards on slopes, not sideways.

Be especially careful when driving on slopes.

Children

???Serious accidents may occur if you fail to be on your guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing. Never assume that children will remain where you last saw them.

???Keep children away from the area to be mowed and under close supervision by another adult.

???Keep an eye out and shut off the machine if children enter the work area.

???Before and during reversing procedures, look behind you and down for small children.

???Never allow children to ride along. They can fall off and seriously injure themselves or be in the way for safe manoeuvring of the machine.

???Never allow children to operate the machine.

???Be particularly careful near corners, bushes, trees or other objects that block your view.

Never allow children to operate the machine.

Maintenance

???Stop the engine. Prevent starting by removing the ignition cable from the spark plug or remove the ignition key before making any adjustments or carrying out maintenance.

???Never fill the fuel tank indoors.

???Petrol and petrol fumes are poisonous and extremely flammable. Be especially careful when handling petrol, as carelessness can result in personal injury or fire.

???Only store fuel in containers approved for the purpose.

???Never remove the fuel cap and fill the petrol tank while the engine is running.

???Allow the engine to cool before refuelling. Do not smoke. Do not fill petrol in the vicinity of sparks or naked flames.

Never fill the fuel tank indoors.

???If leaks arise in the fuel system, the engine must not be started until the problem has been resolved.

???Store the machine and fuel in such a way that there is no risk that leaking fuel or fumes can cause any damage.

???Check the fuel level before each use and leave space for the fuel to expand, because the heat from the engine and the sun may otherwise cause the fuel to expand and overflow.

???Avoid overfilling. If you spill petrol on the machine, wipe up the spill and wait until it has evaporated before starting the engine. If you spill petrol on your clothing, change your clothing.

???Allow the machine to cool before performing any actions in the engine compartment.

???Be especially careful when handling battery acid. Acid on the skin can cause serious corrosive injuries. In the event of spillage on the skin wash immediately with water.

???Acid in the eyes can cause blindness, contact a doctor immediately.

???Take care with battery maintenance. Explosive gases form in the battery. Never perform maintenance on the battery while smoking or in the vicinity of open flames or sparks. This can cause the battery to explode and cause serious injuries.

???Make sure all nuts and bolts are tightened correctly and that the equipment is in good condition.

???Do not modify safety equipment. Check regularly to be sure it works properly. The machine must not be driven if protective plates, protective covers, safety switches or other protective devices are not fitted or are defective.

???Do not change the setting of governors and avoid running the engine at excessively high revs. If you run too fast, you risk damaging the machine components.

WARNING!

The engine and the exhaust system become very hot during operation.

Risk of burn injuries if touched.

WARNING!

The battery contains lead and lead pollutants, chemicals that are considered to cause cancer, birth defects or other repro- ductive impairment. Wash your hands after touching the battery.

Do not smoke when carrying out maintenance.

???Never use the machine indoors or in spaces lacking proper ventilation. Exhaust fumes contain carbon monoxide, an odourless, poisonous and highly dangerous gas.

???Stop and inspect the equipment if you run over or into anything. If necessary, make repairs before starting.

???Never make adjustments with the engine running.

???The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer.

???The blades are sharp and can cause cuts. Wrap the blades or wear protective gloves when handling them.

Throttle and Choke lever

The engine speed is adjusted with the throttle control, and thereby also the rotation speed of the blades.

The control is also used to activate the choke function. When the choke is used the engine receives a richer mixture of fuel and air, which simplifies cold start.

Speed limiter

The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards and pedal (2) for reversing.

WARNING!

Make sure that branches do not obstruct the pedals when mowing under bushes, otherwise you may lose control.

Parking brake

The parking brake is applied as follows:

1.Press down the brake pedal.

2.Press in the lock button on the steering column.

3.Release up the brake pedal while holding the button pressed.

The lock on the parking brake automatically disconnects when the brake pedal is pressed.

Cutting unit

The Rider 16 can be fitted with four different cutting units.

Rear ejector - 970 mm

See ???Maintenance \ Checking the Blades??? for identification of the cutting unit.

Seat

The seat has a jointed attachment on the front edge and can be tipped forward.

The seat can also be adjusted lengthways.

Release the knobs under the seat and adjust it forwards or backwards to the required position.

Lock the setting with the knobs.

Fuelling

The engine should be run on 85 octane (or higher) unleaded petrol/gasoline (no added oil). Environmentally adapted alkylate fuel is also recommended.

WARNING! Petrol/gasoline is highly

inflammable. Observe care and fill up with fuel outdoors (see safety instructions).

???Read the safety instructions and information on the location and function of the controls before starting (see pages 5-14).

???Conduct daily maintenance before starting (see maintenance schedule on page 20).

Adjust the seat to the required position.

Starting the engine

1.Lift up the cutting unit by pulling the lever backwards to locked position (transport posi- tion).

2.Apply the parking brake. This is done as follows:

???Press down the brake pedal (1).

???Press in the lock button on the steering column (2).

???Release the brake pedal while the button is held pressed.

The parking brake lock disconnects automati cally when the brake pedal is pressed down.

1

Cold engine:

3.Push the throttle control to position 3 (choke position). In this position the engine receives a richer mixture so that the engine starts more easily.

Warm engine:

4.Set the throttle control midway between position 1 and 2.

5. Turn the ignition key to start position.

IMPORTANT INFORMATION

Do not run the starter for more than about 5 seconds at a time. If the engine does not start, wait about 10 seconds before trying again.

6.When the engine has started release the ignition key to neutral position.

Push the throttle control to the required speed. For cutting 3/4 to full throttle.

WARNING!

Never run the engine indoors, in enclosed or poorly ventilated areas. The exhaust fumes contain toxic carbon monoxide.

3.Select the required cutting height (1-9) with the cutting height lever.

To obtain a uniform cutting height it is important that the tyre pressures are equal on both front wheels (60 kPa).

4.Push in the lock button on the lift lever and lower down the cutting unit.

IMPORTANT INFORMATION

The service-life of the drive belts increases considerably if the engine is run at low speed when engaging the blades. For this reason do not increase the throttle until the cutting unit has been lowered to the cutting position.

Cutting tips

???Localise and mark stones and other fixed objects to avoid collision.

???Start with a high cutting height and reduce down until the required cutting result are obtained.

???The cutting results are best with a high engine speed (fast rotating blades) and low driving speed (slow moving machine). If the grass is not too high and thick, the driving speed can be increased without noticeably depreciating the mowing result.

6007-212

Mowing pattern

???The best lawns are achieved if the grass is cut often. Mowing becomes more uniform and the grass cuttings become more evenly distributed over the surface. The total time consumption is not greater since it is possible to select a higher driving speed without inferior mowing results.

???Avoid mowing a wet lawn. The mowing results are inferior since the wheels sink down into the soft lawn.

???Wash down the underside of the cutting unit with water after use. Do not use a high pressure jet. Put the cutting unit in the service position while doing this.

???If you use the BioClip unit it is important to mow the grass regularly.

WARNING!

Clear the lawn from stones and other object which can be thrown out by the blades.

WARNING!

Never drive the machine on ground with a slope of more than 15??. Mow slopes upwards and downwards, never across. Avoid sudden changes in direction.

Stopping the engine

Preferably allow the engine to idle for a minute to obtain normal working temperature before stopping it if it has been working hard.

1.Lift up the cutting unit by pulling the lever back to the end position.

2.Pull back the throttle control and turn the ignition key to the STOP position.

3. When the Rider is at a standstill, press down the parking brake and push in the locking button.

Release lever

The release control must be pulled out in order for the Rider to be moved when the engine is shutoff.

Front hood

Release the clip on the front hood and lift off the fender.

Right-hand fender

Remove the knob (1), the screws (2 and 3) and lift off the hood.

Checking and adjustment of the steering wires

The steering is controlled by means of wires.

These can in time become slack, which implies that the adjustment of the steering becomes altered.

Check and adjust the steering as follows:

1.Dismantle the frame-plate by releasing the screws (two on each side).

3.When necessary the wires can be tensioned by tightening the adjusting nuts, one on each side of the steering rim.

Do not tension the wires too tightly, they should only be tightened up to the steering rim.

Check the wire tension on completion of the adjustment as per item 2.

Adjusting the brake

The brake is adjusted as follows:

1.Release the lock nuts (1).

2.Tension the wire with the adjusting screw (2) until all the play in the wire is taken up.

3.Tighten the lock nuts (1).

4.The brakes should be checked again after the adjustment has been made.

WARNING!

Poorly adjusted brakes can result in reduced braking power.

Checking and adjustment of the throttle wire

If the engine does not respond as it should do when the throttle lever is moved or if the top speed is not reached, the throttle wire may need adjusting.

1.Loosen the clamping screw (by the arrow), and slide the throttle to the choke position.

2.Pull the throttle wire???s casing as far as possible to the right and check that the choke is fully actuated.

3.Tighten the clamping screw.

4.Pull back the throttle to the full throttle position and check that the choke is no longer actuated.

Replacement of the fuel filter

Replace the pipe fitted fuel filter every 100 running hours (once per season) or more frequently if it is clogged.

Replace the filter as follows:

1.Fold open the engine cover as described on page 19.

2.Move the hose clips away from the filter. Use a pair of flat pliers.

3.Pull off the filter from the hose ends.

4.Press in the new filter on the hose ends. If necessary soap solution can be applied on the filter ends to simplify fitting.

5.Push the hose clips back on the filter.

Replacing the air filter

If the engine seems to lack power or goes irregularly the reason may be that the air filter is clogged.

It is therefore important to replace the air filter at regular intervals (see ???Maintenance schedule??? on page 20 for correct service interval).

1. Fold open the engine cover.

2.Remove the air filter housing???s plastic cover by releasing the wing-nut.

3.Remove the wing-nut on the air filter and lift off the paper filter with pre-filter.

4.Pull off the foam plastic pre-filter from the paper filter and wash clean in mild detergent.

Squeeze it dry in a clean cloth.

Drench it with new engine oil. Wrap the filter in an absorbent cloth and squeeze out excess oil.

Replace the paper filter if it is clogged with dirt.

IMPORTANT INFORMATION

Do not use compressed air to clean the paper filter.

5.Fit the air filter as follows:

Push the pre-filter over the paper filter.

Fit the paper filter with pre-filter in the air filter housing and tighten the wing-nut.

Replace the plastic cover oven the air filter housing and tighten the wing-nut.

Checking of the fuel pump???s air filter

Check regularly that the fuel pump???s air filter is free from dirt.

The filter can when necessary be cleaned with a brush.

Check the level of the battery acid

Check that the level of the battery acid lies between the markings. Top up the cells with only distilled water.

WARNING!

Procedures on contact with acid

External: Rinse well with plenty of water.

Internal: Drink large quantities of water or milk. Contact a doctor as soon as possible.

Eyes: Rinse well with plenty of water. Contact a doctor as soon as possible.

Batteries emit explosive gas. Sparks, flames and cigarettes must absolutely not be brought into the vicinity of the battery.

Ignition system

The engine is equipped with an electronic ignition system. Only the spark plug requires maintenance.

For recommended spark plug, see chapter ???Technical data???.

IMPORTANT INFORMATION

Fitting the wrong spark plug type can damage the engine.

1.Remove the ignition cable shoe and clean around the spark plug.

2.Remove the spark plug with a 13/16" (21 mm) spark plug socket wrench.

3.Check the spark plug. Replace the spark plug if the electrodes are burned or if the insulation is cracked or damaged. Clean the spark plug with a steel brush if it is to be reused.

4.Measure the electrode gap with a gapping tool. The gap should be 0.75 mm/0.030". Adjust as necessary by bending the side electrode.

5.Reinsert the spark plug, turning by hand to avoid damaging the threads.

IMPORTANT INFORMATION

Inadequately tightened spark plugs can cause overheating and damage the engine. Tightening the spark plug too much can damage the threads in the cylinder head.

6.After the spark plug is seated, tighten it using a spark plug wrench so that the washer is compressed. A used spark plug should be turned 1/8???1/4 of a turn from the seated position. A new spark plug should be turned 1/2 a turn from the seated position.

7.Replace the ignition cable shoe.

Inspecting the safety system

The Rider is equipped with a safety system that prevents starting or driving under the following conditions:

The engine should only be possible to start when the cutting unit is in its raised position and the hydrostat pedals are in the neutral position.

The driver does not need to be seated in the driver???s seat.

Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met. Change the conditions and try again.

Check that the engine stops if you temporarily move out off the driver???s seat while the cutting unit is lowered or the hydrostat pedals are not in the neutral position.

Checking the tyre pressure

The tyre pressure should be 60 kPa (0.6 kp/cm2) all round.

To improve driving the pressure on the rear tyres can be reduced to 40 kPa (0.4 kp/cm2).

The maximum tyre pressure is 100 kPa (1.0 kp/cm2).

IMPORTANT INFORMATION

Different tyre pressures on the front tyres will result in the blades cutting the grass at different heights.

Check the engine???s cooling air intake

Fold open the engine cover as described on page 19.

Check that the cooling intake is free from leaves, grass and dirt.

If the cooling intake is blocked this will interfere with the cooling of the engine, which can damage the engine.

Fitting the cutting unit

1.Place the Rider on a flat surface and apply the parking brake. Check that the lever for setting the cutting height is in the lowest position.

Make sure the support wheels are fitted to the cutting unit (1).

2.Grasp the handle at the front (BioClip 90) or hold the frame of the cutting unit (2) and slide the unit underneath the rider mower, making sure that the tongue on the cutting unit (3) engages correctly.

1.Check the air pressure in the tyres 60 kPa (0.6 kp/cm2).

2.Place the Rider on a flat surface.

3.Put the lifting lever in the mowing position.

4.Place a set of bathroom scales under the cutting unit???s frame (front edge) so that it rests on the scales. If necessary a block can be placed between the frame and scales so that the support wheels do not bear any weight.

5.Adjust the unit???s ground pressure by screwing in or out the adjusting screws located behind the front wheels on both sides.

The ground pressure should be between 12 and 15 kg.

Checking the cutting unit???s parallelism

Check the parallelism of the cutting unit as follows:

1.Check the air pressure in the tyres 60 kPa (0.6 kp/cm2).

2.Place the machine on a level surface.

3.Put the lifting lever in the mowing position.

4.Measure the distance between the ground and the front and rear edges of the cutting unit hood. The cutting unit should slope forwards slightly so that the rear edge is 2-4 mm higher than the front edge.

Adjusting the parallelism of the cutting unit

1.Remove the front hood and right-hand fender, as described on page 21.

2.Undo the nuts on the lift strut.

3.Unscrew the strut (anticlockwise) to lower the rear edge of the hood.

The dip stick must be fully screwed down.

Now release the dip stick again and pull out. Check the oil level.

The oil level should lie between the markings on dip stick. If the level approaches the ADD mark, top up with oil to the FULL mark.

The oil is filled in the same hole for the dip stick

Use engine oil SAE 30 or SAE 10W/30, class SF- CC.

The total oil volume in the engine is 1.2 litres.

1.Place a receptacle under the engine???s drain plug, located on the left-hand side of the engine.

2.Remove the dip stick and drain plug.

3.Let the oil run out into the receptacle.

4.Fit the drain plug and tighten.

5.Fill up with oil to the FULL mark on the dip stick. The oil is filled in the same hole for the dip stick. Use engine oil SAE 30 or SAE 10W/30, class SF-CC.

Use engine oil with min. API SF quality and SAE 30 or SAE 10W/30 viscosity grade. The oil volume in the engine is 1.2 litres.

6.Run the engine warm and then check that there is no leakage from the drain plug.

IMPORTANT INFORMATION

Used engine oil is hazardous to health and environment and must in accordance with the law not be poured out on the ground or in the nature, and must be handed in to a workshop or other designated station for treatment. Avoid skin contact, wash with soap and water in the event of spillage.

Check the transmission???s oil level

1.Remove the transmission cover. Loosen both screws (one on each side) and lift off the trans- mission cover.

2.Check that there is oil in the transmission???s oil tank. Fill if necessary with engine oil SAE 10W/ 30 (class SF???CC).

Lubricating the belt adjuster

The belt adjuster should be lubricated regularly using good quality molybdenum disulphide grease*.

1 nipple from the right-hand side under the engine???s lower belt pulley, until grease is forced out.

With daily use lubrication should be conducted twice a week.

General lubrication

All joints and bearings are lubricated on manufacture with molybdenum sulphide grease. Re-grease with same type of grease*. Lubricate the steering and control wires with engine oil.

The machine should be lubricated regularly, and twice a week when used daily.

* Grease from well-known brand names (petrol companies, etc.) usually maintains a good quality. The most important property is that the grease provides good protection against corrosion.

Winter storage

At the end of the season the machine should immediately be put in order for storage, also if it is going to stand idle for more than 30 days. Fuel which is left to stand for long periods (30 days or more) can leave tacky deposits which can block the carburettor and interfere with the engine.

Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage. If alkylate petrol (Aspen) is used stabiliser is not necessary since this fuel is stable. However, one should avoid changing from standard to alkylate petrol since sensitive rubber parts can harden. Add stabiliser to the fuel in the tank or the storage container. Always use the mixing ratios indicated by the manufacturer. Run the engine for at least 10 minutes after adding the stabiliser so that it will reach the carburettor. Do not empty the fuel tank and carburettor if stabiliser has been added.

WARNING!

Never place an engine with fuel in the tank indoors or in poorly ventilated areas where petrol fumes can come into contact with naked flames, sparks or pilot flames in boilers, hot water heaters, or

drying cabinets, etc. It is highly inflammable and negligent usage can cause severe person injury and material damage. Drain off the fuel in an approved container outdoors and well clear of naked flames. Never use petrol for cleaning purposes. Use degrea- sing agents and hot water instead.

To put the machine in order for storage follow these instructions:

1.Carefully clean the machine, especially under the cutting unit. Touch-up paint damage to avoid rust.

2.Inspect the machine for worn or damaged parts and tighten loose screws and nuts.

3.Change the oil, and take care of the waste oil.

4.Empty the fuel tank. Start the engine and run it until the carburettor is emptied of fuel.

5.Remove the spark plug and pour about a tablespoon of engine oil in the cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plug.

6.Grease all grease nipples, joints and axles.

7.Remove the battery. Clean it, charge it, and store it is a cool place.

8.Store the machine is a clean and dry place and cover it over for extra protection.

Service

When ordering spare parts state the purchase year, model, type, and serial number.

Always use genuine parts.

Annual inspection or trimming by an authorised service workshop is a good way of getting the best out of your machine the next season.
