G6050 Round Head Framing Nailer Kit-10-
Replacing Pistons/O-Rings
If you use your nailer day in and day out,
Grizzly offers repair pistons as cheap
insurance against wasted down time and
lost profits in the event that a piston or pis-
ton shaft becomes worn out. To replace a
piston:
Figure 7. Removing nailer exhaust cap.
8. With a long flathead screwdriver or
similarly shaped tool, push the piston
shaft back inside the nailer until you
can grip the piston head and remove
it from the cylinder. (Be careful not to
scratch the discharge area when
pushing the piston shaft with the
screwdriver.)
9. Place a new O-ring on the new piston
and apply a thin film of the nailer lubri-
cating oil on the O-ring.
10. Insert the new piston in the cylinder.
Make sure that the grooves on the
piston shaft line up with those on the
guide at the bottom of the cylinder.
The new piston should easily slide
into the cylinder. Do not force the
piston into the cylinder! If the piston
is not easily inserted, double-check
the alignment of the piston shaft with
the grooves on the guide.
11. After the piston is inserted correctly,
close the magazine. Replace the rear
cap assembly and tighten the 4 cap
screws.
12. For more assistance, or to install a
complete O-ring set, refer to the
appropriate breakdown diagram in the
back of this manual.
Always disconnect air from nailer
whenever servicing! During mainte-
nance, a nailer connected to air may
fire accidentally, causing serious
personal injury!
1. Disconnect the nailer from the air
supply!
2. Remove all nails from the magazine
cartridge.
3. Remove the 4 cap screws from the
nailer exhaust cap.
4. Remove the exhaust cap as shown in
Figure 7.
5. The top of the piston should now be
visible inside the cylinder, which is
housed in the head of the nailer.
6. Open the magazine.
7. Watch the discharge area and push
the top of the piston with your finger.
You will see the piston shaft slide
down the discharge area.
