Replacing Pistons/
O-Rings
Under heavy use, the piston or O-rings
may wear out. Replacement is quick and
easy. Contact your authorized Shop Fox
dealer to obtain the Piston Repair Kit
(Part Number X1785127), or the Complete
O-Ring Kit (Part Number X1785128).
5.
Take hold of the ram pin and pull the
piston from the cylinder.
6.
Place the new O-ring on the new
piston, and apply a thin film of tool
oil on the O-ring.
7.
Insert the new piston in 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, check
the alignment of the piston inside the
cylinder.
8.
After the piston is inserted correctly,
place the cylinder back in the nailer
housing. If seated correctly, the
cylinder will snap into place.
9.
Push the cylinder collar down into
the housing as far as it will go. The
horizontal air slots on the side of the
cylinder should be visible.
10.
Replace the rear cap and secure it
with the four cap screws.
11.
Re-install the flat washer,
compression spring, depth guide,
and nose piece onto the front of the
nailer, and use a 19mm wrench to
tighten the nose piece.

washer.
3.

cap, then remove the cap.
4.

of the nailer. This will push the
cylinder free of the housing.

ous personal injury!
