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.
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.
