Additional Safety Instructions for Nailers
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 pressurized oxygen or other combustible gases as a power source. Only use fil- tered, lubricated, and regulated compressed air.
3.SAFE HANDLING: Never point the nailer at others! Do not keep the trigger pulled when loading fasten- ers, 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.CLEANING: Never use gasoline or other flammable liquids to clean the nailer; vapors in the nailer will ignite by a spark and cause it to explode.
5.HOSE USAGE: 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.
6.OPERATING QUESTIONS: If you are not sure about the intended operation, stop using the nailer. Seek formal training or research books or magazines that special- ize in pneumatic tools.
7.MAINTENANCE: Always discon- nect air from the nailer when ser- vicing or installing nails. During maintenance, a nailer connected to air may fire accidentally, caus- ing serious personal injury.

Compressed Air
System
The Model H6145 is designed to be oper- ated at
Before using your new nailer, regulate the air pressure on your air compressor to the minimum PSI for your model.
An
This filter/lubricator/regulator unit will protect your tool from damaging water
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 Yoke
A safety yoke mechanism (bump fire) on the nose of the nailer acts as a second- ary safety device. When the trigger is pressed, the nailer will not fire until the safety yoke mechanism is depressed.
Before you use your nailer for the first time, check the safety yoke 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 yoke mechanism move up and down without sticking.
4.Connect the nailer to the air supply.
5.Without pressing the trigger, depress the safety yoke 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 yoke 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)
???If the nailer fires when the trigger is pulled, without the safety yoke mechanism being depressed, then the nailer is not working properly.
???If either of these two conditions develop after you have used your nailer for a period of time, check the lubrication of these mechanisms.
The safety yoke is a mechanical device that can fail. Never rely on the safety yoke mechanism as an excuse to point the nailer at yourself or any bystanders. Serious injury may occur.

4.Slide the nails all the way down to the nose of the nailer.
5.Release the catch lever. The pusher slides forward until it rests against the nail stick.
Operating
If you have not read the safety instruc- tions in this manual, do not operate the nailer.
Before you operate your nailer, place five 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 connect fitting.
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.Pull the trigger and depress the safety yoke mechanism on 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
The nose of the gun houses a depth adjust- ment mechanism for setting the nail depth.
To adjust the depth:
1.DISCONNECT NAILER FROM THE
AIR SUPPLY!
2.If the nail is driven too far into the workpiece, loosen the cap screw on the safety nose with a 4mm wrench, as shown in Figure 6.
Figure 6. Loosening cap screw for depth adjustment.
3.Slide the safety nose (Figure 6) toward the nailer body to drive nails deeper. Slide the safety nose forward if the nail goes too deep.
4.Tighten the safety nose cap screw each time after making adjustments.
5.Connect to the air.
6.Pull the trigger and depress the safety yoke mechanism on your workpiece to test the depth adjustment.
The nailer is designed to fire one nail at a time, or one after another, using the safety yoke mechanism.
To operate your nailer in single fire mode:
1.Depress the safety yoke mechanism against the workpiece.
2.Pull the trigger, then remove your finger from the trigger after the nail is driven.
To operate your nailer in bump fire mode:
1.Pull the trigger.
2.Press the safety yoke mechanism against your workpiece and raise it after the nail is driven.
3.Hold the trigger and repeat Step 2 to drive more nails.
A jammed nail must be cleared before using the nailer again. The two places where a nail can get jammed are the maga- zine and the discharge area.
To clear a jammed nail from the maga- zine:
1.DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Pull back and lock the magazine push- er.
3.Remove the nail stick.
4.Locate and remove the jammed nail with needle nose pliers. Release the catch lever and let the pusher slide to front of the magazine.
To clear a jammed nail from the dis- charge area:
1.DISCONNECT NAILER FROM THE
AIR SUPPLY!
2.Pull back and lock the magazine push- er in place.
3.Remove all nails from the magazine.
4.Locate the nail in the nailer nose, dis- lodge the nail with a tool that will fit in the slot on the underside of the nose.
5.Throw the damaged nail away and insert a new nail stick that only con- tains clean, undamaged nails. DO NOT use dirty or damaged nails!
6.Release the catch lever and let the pusher slide to the front of the maga- zine.

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.
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.
4.Remove the top cap.
5.The top of the piston should now be visible inside the cylinder, which is housed in the head of the nailer.
6.Open the magazine.
7.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.
8.With a long flathead screwdriver or similarly 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 push- ing the piston shaft with the screw- driver.)
9.Place a new
10.Insert the new piston in the cylinder. Make sure that the grooves on the piston shaft line up with those on the guide at the bottom of the cylinder. The new piston should easily slide into the cylinder. DO NOT force the piston into the cylinder! If the piston is not easily inserted,
11.After the piston is inserted correctly, close the magazine. Replace the top cap assembly and tighten the 4 cap screws.
12.For more assistance, or to install a complete
CLEANING & LUBRICATION
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 dam- age 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!
Special 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 7) before every use, or after 2 hours of continuous use.
Wipe off any excess oil near the nailer exhaust to avoid dust
Another option to manual oiling would be to install a lubricator in your air compres- sor 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 lubri- cator.
As mentioned before, the best option is to install a filter/lubricator/regulator unit in your air line.
