Safe operation practices for ride-on mowers

IMPORTANT!

This cutting machine is capable of amputating hands and feet and throwing objects. Failure to ob- serve the following safety instructions could result in serious injury or death.

I.General operation

1.Read, understand and follow all instructions in the manual and on the machine before start- ing.

2.Only allow responsible adults, who are familiar with the instructions, to operate the machine.

3.Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade.

4.Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area.

5.Never carry passengers.

6.Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing.

7.Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place.

8.Slow down before turning.

9.Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine and remove keys before dismounting.

10.Turn off blades when not mowing.

11.Stop engine before removing grass catcher or unclogging chute.

12.Mow only in daylight or good artificial light.

13.Do not operate the machine while under the influence of alcohol or drugs.

14.Watch for traffic when operating near or crossing roadways.

15.Use extra care when loading or unloading the machine into a trailer or truck.

II.Slope operation

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

DO

Mow up and down slopes, not across. Remove obstacles such as rocks, tree limbs, etc.

Watch for holes, ruts or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

Use slow speed. Choose a low gear so that you will not have to stop or shift while on the slope.

Follow the manufacturer???s recommendations for wheel weights or counterweights to improve stability.

Use extra care with grass catchers or other attachments. These can change the stability of the machine.

Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.

Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and pro- ceed slowly straight down the slope.

DO NOT

Do not turn on slopes unless necessary and then, turn slowly and gradually downhill, if possible.

Do not mow near drop-offs, ditches or embandments. The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.

Do not mow on wet grass. Reduced traction could cause sliding.

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

Do not use grass catcher on steep slopes.

III. Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

1.Keep children out of the mowing area and under the watchful care of another responsible adult.

2.Be alert and turn machine off if children enter the area.

3.Before and when backing, look behind and down for small children.

4.Never carry children. They may fall off and be seriously injured or interfere with safe machine operation.

5.Never allow children to operate the machine.

6.Use extra care when approaching blind cor- ners, shrubs, trees or other objects that may obscure vision.

If your machine has a hydrostatic transmission you should only tow it very short distances at low speed if absolutely necessary, otherwise the transmission may be damaged.

Intended use

This machine is designed solely for cutting grass on conventional lawns and other cleared and leveled ground without obstacles, as rocks, stumps etc., and, in conjunction with accessories supplied by the manufacturer even for other special tasks for which instructions are delivered with the acces- sory. Use in any other way is considered as con- trary to the intended use. Compliance with and strict adherence to the conditions of operation, service and repair as specified by the manufacturer also constitute essential elements of the intended use.

This machine should be operated, serviced and repaired only by persons who are familiar with its particular characteristics and who are acquainted with the relevant safety procedures.

Accident prevention regulations, all other generally recognised regulations on safety and occupational medicine, and all road traffic regulations must be observed at all times.

Any arbitrary modifications carried out to this machine may relieve the manufacturer of liability for any resulting damage or injury.

Safe operation practices for Ride-On Mowers

Before starting cutting operations, train different driving operations on an open ground without people nearby until you feel familiar with handling the equipment. This is particularly important if you have no or little prior experience of driving a vehi- cle.

Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-related injuries. These operators should evaluate their ability to operate the riding mower safely in order to protect themselves and others from serious injury.

Never carry children, even with the blades off. They may fall off and be seriously injured or interfere with safe machine operation.

Danger, keep hands and feet away

Driving on slopes

Driving on slopes is one of the situations where there is the most serious risk that the driver can loose control or that the machine tips over, which can cause severe injuries or be fatal. All slopes require extra care. If you cannot reverse up the slope or if you feel uncertain avoid cutting it.

Do as follows:

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

???Cut upwards and downwards, not sideways.

???Look out for and avoid driving over furrows, holes or mounds. On uneven surfaces it is easier for the machine to tip over. High grass can conceal obstacles.

???Drive slowly. Select a low gear to avoid having to stop and changing gear. It is also easier to use the gear to brake in a low gear.

???Follow the manufacturer???s recommendations on wheelweights or counterweights to increase stability.

???Be extra careful with the grass collector or other equipment which can alter the stability of the machine.

???Always drive smoothly and slowly on slopes. Avoid sudden changes of speed or direction.

???Avoid starting or stopping on a slope. If the tyres begin to skid switch of the blades and drive slowly down the slope.

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

Be extra careful when driving on slopes.

Cut slopes upwards and downwards, not sideways.

6 ??? English

SAFETY INSTRUCTIONS

???Do not cut close to edges, ditches or banks. The machine can suddenly tip over if a wheel goes over the edge of a drop or a ditch, or if a bank gives way.

???Do not cut wet grass. It is slippery and the tyres can loose their grip so that the machine slides.

???Do not try to stabilise the machine by placing one foot on the ground.

???Always keep the rider mower away from edges or ditches when cleaning the chassis.

Children

Tragic accidents can occur if the driver does not pay attention to children in the vicinity. Children are often attracted to the machine and the work of mowing.

Never assume that children stay where you last saw them.

???Keep children away from the mowing area and under the supervision of another adult.

???Be on your guard and switch off the machine if children come into the work area.

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

???Never allow children to ride on the machine. They can fall off and become seriously injured or obstruct a risky manoeuvre of the machine.

???Never allow children to drive the machine.

???Be extra careful close to corners, bushes, trees or other objects which obstruct your view.

Maintenance

???Petrol/gasoline and petrol/gasoline fumes are toxic and highly inflammable. Be extra careful when handling petrol/gasoline.

a.Store the fuel in containers approved for this purpose.

b.Never fill up the machine with fuel when the engine is running. Let the engine cool before filling up with fuel. Do not smoke, or fill up with fuel in the vicinity of naked flames or sparks.

PRESENTATION

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.

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 discon- nects when the brake pedal is pressed.

column (2).

DRIVING

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 igni- tion 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.

14 ??? English

DRIVING

Driving the machine

1.Release the parking brake by pressing down the brake pedal.

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).

English ??? 15

DRIVING

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 in- creases considerably if the engine is run at low speed when engaging the blades. For this reason do not increase the throt- tle 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 or the engine speed reduced without noticeably affecting the mowing results.

???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.

Mowing pattern

???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.

!WARNING!

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

16 ??? English

DRIVING

!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.

Release lever

In order to move the machine when the engine is switched off the release lever must be pressed down and forwards.

Restoring from service position

To restore the machine from the service position, reverse the sequence ???Placing in Service position???.

MAINTENANCE

Lubrication

The following two lubrication points should be regularly lubricated with high quality graphite grease.

With daily use lubrication should be conducted twice a week.

General lubrication

All joints and bearings are lubricated on manufac- ture 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.

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.

MAINTENANCE

Checking the blades

To achieve the best mowing results it is important that the blades are undamaged and well-sharpened.

Check that the blades??? attachment screws are tight.

IMPORTANT INFORMATION

Replacing or sharpening the blades should be conducted by an authorised service workshop.

IMPORTANT INFORMATION

On the Bioclip unit the relative positioning of the blades should always be as shown in the diagram with an angle of 90?? between the blades. Otherwise the blades can go against each other and damage the unit.

MAINTENANCE

Changing the oil

The oil should be changed for the first time after 5 hours of running time. Thereafter it should be changed every 25 hours of running time.

!WARNING!

Engine oil can be very hot if it is drained off directly after the engine is stopped. Therefore allow the engine to cool down first.

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 CD-SF.

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.

MAINTENANCE

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. Release the clamping screw (see arrow) and push the throttle control to full throttle position.

2.Pull the throttle wire???s outer casing to the far right and tighten the clamping screw.

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. Dismantle the engine hood as described on page 17.

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.

STORAGE

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 degreasing 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 plug and pour in a tablespoon of engine oil in each cylinder. Pull round the engine to distribute the oil and screw the plug back on.

6.Grease all grease nipples, joints and axles.

7.Remove the battery. Clean it, charge it, and store it is a cool place. Protect the battery from low temperatures (below freezing point).

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.
