Maintenance requirements are minimal for this nail gun. The two most common problems with any nail gun are jamming and damaged drivers. In both cases, the gun will need to be partially diassembled to make the repairs.

The third most common problem is replacing worn out O-rings. This is quite easily done, but extensive disassembly will be required. We suggest consulting with the Grizzly service staff for special instructions if needed. Grizzly has replacement parts and a special O-ring rebuilding kit available for this tool. Please call or write the appropriate service location listed on page one of this manual for prices and ordering information.

Again, if repairs become necessary that are beyond the scope of this manual, do not hes- itate to call or write the appropriate service location.

IX. MAINTENANCE

A. JAMMING

To repair a jam:

1.Disconnect gun from the air supply.

2.Remove any fasteners remaining in the gun.

3.Open the nose by unlocking the safety clip.

4.Using needle nose pliers, remove any bent fasteners lodged in the gun nose.

5.Close the nose and re-lock the safety clip.

6.Re-load fasteners and connect nail gun to the air supply.

7.Make sure the safety nose is functioning correctly and that it slides freely in its guide. Test fire into a sample piece after following all operational and safety proce- dures discussed earlier.

If jamming persists, make sure you are using fasteners within the size range of this gun. If jamming is due to worn or broken parts, repair or replace them before placing the gun back into service. For example, a worn or damaged driver may cause jamming. If the driver tip is worn, you may be able to recondition the tip by filing it square again. In any event, you must remove the damaged driver from the gun. See Section IX.B.
