1.KEEP ALL SAFETY DEVICES IN PLACE and in working order.

2.REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of check- ing to see that keys and adjusting wrenches are removed from tool before operation.

3.KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

4.DO NOT USE IN DANGEROUS ENVIRONMENT. Do not use pneu- matic tools in damp or wet loca- tions, or where any flammable or noxious fumes may exist. Keep work area well lighted.

5.KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept at a safe distance from work area.

6.MAKE WORKSHOP CHILD PROOF by locking your shop and shutting off air valves.

7.DO NOT FORCE TOOL. It will do the job better and safer at the rate for which it was designed.

8.USE THE RIGHT TOOL. Do not force tool or attachment to do a job for which it was not designed.

9.DO NOT USE UNDER THE

INFLUENCE OF DRUGS OR

ALCOHOL.

10.USE PROPER AIR HOSE for the tool. Make sure your air hose is in good condition and is long enough to reach your work without stretching.

11.WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neck- ties, rings, bracelets, or other jew- elry which may get caught in moving parts. Non-slip footwear is recom- mended. Wear a protective hair cov- ering to contain long hair.

12.ALWAYS USE SAFETY GLASSES.

Also use a face or dust mask if oper- ation is dusty. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.

13.WEAR APPROVED HEARING PROTECTION. Air escaping from pneumatic tools can exceed safe exposure limits and may cause hearing damage with prolonged exposure.

14.SECURE WORK. Use clamps or a vise to hold work when practical. It is safer than using your hand and frees both hands to operate tool.

15.MAINTAIN TOOLS WITH CARE.

Keep tools lubricated and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

16.REDUCE THE RISK OF UNINTENTIONAL FIRING. Do not carry tool with hand on trigger and always disconnect from air when not in use.

17.DISCONNECT TOOLS before ser- vicing, changing accessories, or moving to another location.

18.DO NOT OVERREACH. Keep proper footing/balance at all times.

19.USE THE RECOMMENDED ACCESSORIES. Consult owner???s manual for recommended acces- sories. The use of improper acces- sories may cause risk of injury.

20.CHECK FOR DAMAGED PARTS BEFORE USING. Check for bind- ing and alignment of parts, broken parts, part mounting, loose bolts, and any other conditions that may- affect machine operation. Repair or replace damaged parts.

21.NEVER LEAVE UNATTENDED

TOOL CONNECTED TO AIR.

Disconnect the air hose and do not leave tool until it is relieved of any built up pressure.

22.NEVER ALLOW UNTRAINED

USERS TO USE THIS TOOL

WHILE UNSUPERVISED.

23.IF YOU ARE UNSURE OF THE

INTENDED OPERATION, STOP USING TOOL. Seek formal training or research books or magazines that specialize in pneumatic tools.

24.BE AWARE OF HOSE LOCATION

WHEN USING PNEUMATIC TOOLS. Hoses can easily become a tripping hazard when laid across the floor or spread out in a disorga- nized fashion.

1.Hand injuries: Do not place

your hands near the nail point of entry. A nail can deflect and tear through the surface of the workpiece, puncturing your hand or fingers.

2.combustible gases: Never connect the nailer to pressur- ized oxygen or other combustible gases as a power source. Only use filtered, lubricated, and regu- lated compressed air.

3.safe handling: Never point the nailer at others! Do not keep the trigger pulled when loading fasteners, carrying, or holding tool. Carry the nailer only by the handle, never by any other part. Do not carry the nailer by the air hose. Disconnect the nailer from the air hose when going up and down ladders.

4.AIR HOSE: Make sure your air hose is designed for the tool in use, is in good condition, and is long enough to reach your work without stretching. However, an overly long air hose in the work area may be a tripping hazard.

5.compressed air rating: Do not connect the nailer to compressed air that exceeds 120 PSI.

6.check valve: Do not use a check valve or any other fitting that allows air to remain in the tool.

7.cleaning: Never use gasoline or other flammable liquids to clean the nailer; vapors in the nailer may ignite by a spark and cause the nailer to explode.

8.OPERATING QUESTIONS: If you are not sure about the intended operation, stop using the nailer. Seek formal training or research sources that specialize in pneumatic tools.

9.Maintenance: Always disconnect air from the nailer when servicing or installing nails. During adjustments or maintenance, a nailer connected to air may fire accidentally, causing serious personal injury.

Operating this nailer can propel objects into the air, causing imme- diate eye damage. To protect your- self, always wear American National Standards Institute (ANSI) approved safety glasses or goggles when oper- ating this equipment. In addition, the intensity of sound made by this nailer at discharge can reach 90 decibels. To protect your hearing, always wear ANSI approved ear protection when operating this nailer.

Read the manual before operation. Become familiar with these nailers, their safety instructions, and opera- tion before beginning any work. Serious personal injury may result if safety or operational information is not understood or followed.

Never point this nailer at yourself or another person! Always pay attention to the direction this nailer is pointed. Use this tool with respect and caution to lessen the possibility of operator or bystander injury. Ignoring this warning may result in serious personal injury.

Nailer accidents routinely happen while moving the gun to another location, such as up ladders, to another room, or even another job site. Always disconnect the gun immediately after use and never transport the gun while connected to the air???even if the air compressor is disconnected from its power source!

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other tools with caution and respect. Failure to do so could result in seri- ous personal injury, damage to equipment or poor work results.

Your Model T20568 left our warehouse in a carefully packed box. If you discover the nailer is damaged after you have signed for delivery, please immediately call Customer Service at (570) 546-9663 for advice.

Save the containers and all packing mate- rials for possible inspection by the carrier or its agent. Otherwise, filing a freight claim can be difficult.

When you are completely satisfied with the condition of the shipment, you should inventory the equipment.

After you open the nailer box, you should find the following.

Compressed Air

System

The Model T20568 is designed to be oper- ated at 60-100 PSI using clean, dry, regu- lated, compressed air. Do not exceed the 120 PSI maximum operating pres- sure for your model.

Before using your new nailer, regulate the air pressure on your air compressor to the minimum PSI for your model.

An in-line filter/lubricator/regulator unit, depicted in Figure 2, can be installed and should be located as close to the nailer as possible.

This filter/lubricator/regulator unit will pro- tect your tool from damaging water build- up, allow you to adjust and maintain con- stant air pressure to your tool, and save you the inconvenience of manually lubri- cating your tool every time you use it.

Exceeding the maximum permissible operating pressure may cause the nailer to explode, blowing metal frag- ments in all directions. To protect yourself from serious personal injury, DO NOT allow your air compressor to exceed the recommended pressure when connected to this nailer!

Check the current Grizzly catalog for avail- ability of this unit. If you plan on install- ing a filter/lubricator/regulator unit in your compressed air system, always follow the connection instructions that come with the unit.

Safety Nose

Mechanism

A safety mechanism on the nose of the nailer protects against accidental firing. When the trigger is pressed, the nailer will not fire until the safety nose mechanism is depressed.

Before you use your nailer for the first time, check the safety nose mechanism to ensure proper function.

To do this:

1.DISCONNECT NAILER FROM THE

AIR SUPPLY!

2. Make sure the magazine is empty and contains no nails.

3.Make sure the trigger and the safety nose mechanism move up and down without sticking.

4.Connect the nailer to the air supply.

The safety mechanism is a mechani- cal device that could fail. Never rely on this mechanism as an excuse to point the nailer at yourself or any bystand- ers. Serious injury may occur.

5.Without pressing the trigger, depress the safety nose mechanism against a scrap piece of wood that is clean and free of any knots, nails, or other foreign objects.

???If the nailer does not fire, then the safety nose mechanism is working correctly.

???If the nailer does fire when you do this, immediately disconnect the nailer from the air supply and call Grizzly Technical Support at (570) 546-9663 for help.

???If the nailer fires when the trigger is pulled, without the safety nose mechanism being depressed, then

the nailer is not working properly. If this occurs, call Grizzly Technical Support at (570) 546-9663 for help.

???If you find that the safety nose mechanism is not working properly, check the lubrication of its sliding components.

Point the nailer away from you and others when connecting the air sup- ply. The nailer can cycle and dis- charge a nail when the air supply is connected. Ignoring this warning may result in serious personal injury.

Loading

When replacing nails in your Model T20568, follow these guidelines:

Gauge: 18

Length: 3/8" ??? 11???4"

Capacity: 100

To load your nailer:

1.DISCONNECT NAILER FROM THE

AIR SUPPLY!

2.Grip the nailer firmly, release the catch lever and slide the magazine pusher open, as shown in Figure 3.

4.Slide the nails all the way down to the nose of the nailer.

5.Slide the pusher back until the catch lever locks.

Operating

If you have not read the safety instruc- tions in this manual, do not operate the nailer.

Before you operate your nailer, place two to six drops of the included oil into the quick connect fitting where the nailer con- nects to the air supply.

To operate your nailer:

1.Connect the air supply to the quick con- nect fitting.

Point the nailer away from you and others when connecting the air supply. The nailer can cycle and discharge a nail when the air supply is connected. Ignoring this warning may result in serious personal injury.

2.To test for proper nail penetration, hold the nailer perpendicular to the surface of a piece of clean scrap wood that is thick enough for the length of nails you have loaded.

3.Depress the safety nose mechanism against your workpiece.

4.Before pulling the trigger, make sure your free hand and other body parts are positioned out of the way of a potential path of a nail in case of deflection.

Deflection is caused when grain irregularities, knots or foreign objects inside the wood cause the nail to change its path, resulting in the nail puncturing the surface of the workpiece, as shown in Figure 5.

Besides damaging your workpiece, deflection can cause injury if your free hand is securing the workpiece in the location that the nail deflects.

Figure 5. Example of nail deflection.

5.Pull the trigger.

???If the nail drove into the wood far enough, continue with your intended operations.

???If the nail either went too far or not far enough, then go to the Adjusting Depth section on this page.

Adjusting Depth

A depth adjustment knob is attached to the nose for setting the nail depth.

To adjust the depth:

1.DISCONNECT NAILER FROM THE

AIR SUPPLY!

2.Rotate the adjustment knob (Figure 6) clockwise to drive the nails deeper or counterclockwise to drive the nails shallower.

Figure 6. Depth adjustment controls.

3.Connect the nailer to the air supply, test the nail depth, and repeat this pro- cedure until the nail depth is satisfac- tory.

Clearing Jammed

Nails

A jammed nail must be cleared before using the nailer again.

To clear a jammed nail from the dis- charge area:

1.DISCONNECT NAILER FROM THE

AIR SUPPLY!

2.Release the catch lever and slide the magazine pusher back.

3.Remove the nail stick from the maga- zine.

4.Open the nailer nose by removing the rubber nose tip, depressing the nose release mechanism, and opening the nose cover as shown in Figure 7.

Figure 7. Nose opened to clear a jam.

5.Dislodge the jammed nail with a tool that will fit in the slot on the underside of the nose.

6.Throw the damaged nail away and insert a new nail stick that only contains clean, undamaged nails. DO NOT use dirty or damaged nails!

7.Slide the pusher back until it locks into position.

Replacing Pistons &

O-Rings

If you use your nailer day in and day out, repair pistons are cheap insurance against wasted down time and lost profits, in the event that a piston or piston shaft becomes worn out. A replacement piston and O-ring kit, part PT20568082, may be purchased for the Model T20568.

Always disconnect air from nailer whenever servicing! During mainte- nance, a nailer connected to air may fire accidentally, causing serious personal injury!

To replace a piston:

1.DISCONNECT NAILER FROM THE

AIR SUPPLY!

2.Remove all nails from the magazine cartridge.

3.Remove the four cap screws on the top of the nailer, near the exhaust port, and remove the cap. The top of the piston should now be visible inside the cylin- der, which is housed in the head of the nailer.

4.Open the nose cover as if to clear a jammed nail.

5.Watch the discharge area and push the top of the piston with your finger. You will see the piston shaft slide down the discharge area.

6.With a long flathead screwdriver or sim- ilarly shaped tool, push the piston shaft back inside the nailer until you can grip the piston head and remove it from the cylinder. (Be careful not to scratch the discharge area when pushing the pis- ton shaft with the screwdriver.)

7.Place a new O-ring on the new piston and apply a thin film of the nailer lubri- cating oil on the O-ring.

8.Insert the new piston in the cylinder. Make sure that the grooves on the pis- ton shaft line up with those on the guide at the bottom of the cylinder. The new piston should easily slide into the cyl- inder. DO NOT force the piston into the cylinder! If the piston is not easily inserted, double-check the alignment of the piston shaft with the grooves on the guide.

9.After the piston is inserted correctly, close the magazine. Replace the top cap assembly and tighten the four cap screws.

10.For more assistance, or to install a complete O-ring set, refer to the break- down diagram in the back of this man- ual for component locations.

Use a good solvent to clean the nose assembly of the nailer. Always be sure that the nailer is dry before using it again.

Do not allow dust, chips, sand, etc. into the air connectors or into the body of the nailer; this may result in leaks and damage to the nailer and the air couplings.

Never use gasoline or other flamma- ble liquids to clean this tool. Vapors in the tool may ignite, causing the tool to explode. Ignoring this warning may lead to serious personal injury or even death!

Pneumatic tool oil has been included with your new Grizzly nailer to help maintain its useful life. Place two to six drops of oil in the nailer air inlet (as shown in Figure 8) before every use, or after 2 hours of continuous use.

Wipe off any excess oil near the nailer exhaust to avoid dust build-up. When the oil that was included with the nailer has been completely used, replace with Grizzly Model G2820 Pneumatic Tool Oil.

Another option to manual oiling would be to install a lubricator in your air compressor line. If your air compressor line already has a lubricator, then regular lubrication of your nailer will not be necessary. Just make sure there is always oil in the lubricator.
