Section 7: Service; Replacing Pistons/O-Rings - Grizzly T27338 Owner's Manual

SECTION 7: SERVICE

Always disconnect air from tool
whenever servicing! During mainte-
nance, tool connected to air may fire
accidentally, causing serious per-
sonal injury!
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.
Disconnect air from nailer whenever
servicing! During maintenance, a
nailer connected to air may fire
accidentally, causing serious injury!
