SECTION 4: MAINTENANCE
Maintenance requirements are minimal for these
nailers. The two most common problems with any
nailer are jamming and damaged drivers. In both
cases, the nailer will need to be partially disas-
sembled to make the repairs.
The third most common problem is worn out O-
rings. Consult the Grizzly service staff for special
instructions if needed. Grizzly has replacement
parts and special O-ring rebuilding kits available
for these tools.
WARNING: All inspections and/or any mainte-
nance is to be performed with the air supply
disconnected from the tool.
Inspect and maintain the following items
daily:
1. Check the air nailer for any loose bolts or air
leaks. Loose bolts should be retightened.
Make sure that all lock washers are in place.
Air leaks are an indication that internal seals
are worn or nicked and should be replaced.
2. Make sure the safety nose and trigger are
functioning properly. Repair as necessary.
Do not use the nailer with a broken or modi-
fied safety nose.
3. Inspect the automatic lubricating system if
applicable and fill as required. Inspect the in-
line air and water filters if applicable and
change or clean as necessary.
4. Inspect the compressor regulator and/or in-
line regulator to ensure that they are set cor-
rectly. Adjust accordingly.
General
CLEANING: Keep the nailer nose as clean as
possible. Dirt and debris have a tendency to work
their way into the nailer from the nose. Wipe off
any dirt that collects on the outside of the nailer
before connecting it to the air supply.
OILING: Keep the nailer oiled. Use special pneu-
matic tool oil to keep internal parts well lubricat-
ed. This tool oil is available through the Grizzly
Catalog (G2820).
If your air supply is not pre-lubricated, you must
add 2 drops of oil directly into the air nozzle at the
rear of the nailer each time the magazine is
loaded. NEVER USE any oil that will corrode the
rubber O-ring seals such as motor oil, detergent
oils, or oils that are used as solvents. Avoid over-
oiling.
IMPORTANT: When you first pick up an air acti-
vated nailer, ALWAYS ASSUME THAT IT IS
LOADED. Open the magazine and inspect for
any nails or staples before connecting it to the air
hose. Do not connect the air supply until you are
in position and ready to operate the nailer.
Cleaning & Oiling
DO NOT load or service any pneumatic nail-
er or stapler without first disconnecting it
from its air source. Failure to do so could
result in a misfire and possible injury.
Ensure that the safety mechanism is work-
ing properly each time you use this tool.
Under no circumstances should the safety
be modified or disabled. Serious injury
could occur.
