SECTION 7: SERVICE
Review the troubleshooting and procedures in this section if a problem develops with your
tool. If you need replacement parts or additional help with a procedure, call our Technical
Support.
Always disconnect air from tool
whenever servicing! During mainte-
nance, tool connected to air may fire
accidentally, causing serious per-
sonal injury!
To replace piston:
1. DISCONNECT NAILER FROM AIR
SOURCE!
2. Remove all nails/staples from maga-
zine and remove guide plate.
3. Remove (4) cap screws shown in
Figure 26 that secure base.
Replacing Pistons/
O-Rings
If you use your nailer day in and day out, pis-
ton repair assemblies (part PT27338026)
and O-ring kits (part PT27338061) are
cheap insurance against wasted down
time and lost profits, in the event that
the piston assembly or O-rings become
worn out. Air leaking from vents under the
head cap can indicate O-rings need to be
replaced.
