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).

Always disconnect nailer from air whenever servicing! During main- tenance, a nailer connected to air may fire accidentally, causing seri- ous personal injury!

To replace a piston, do these steps:

1.DISCONNECT NAILER FROM THE AIR SUPPLY!

2.Use a 19mm wrench to remove the nose piece, then remove the depth guide, compression spring, and flat washer.

3.Use the 4mm hex wrench to remove the four cap screws on the nailer rear cap, then remove the cap.

4.Push the ram pin towards the inside of the nailer. This will push the cylinder free of the housing.

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.
