If the Seal is damaged or has separated from the Main Valve, replace Main Valve. The
Seal and Main Valve have been assembled permanently at the Manufacturing Facility
and can not be repaired in the field.
5. Inspect other O-Rings as described in “Replacing O-Rings” section Figures 12-16 to
ensure proper positioning and distortion has not taken place. If any of the O-Rings are
distorted, refer to the proper Figure and replace.
6. After inspecting and/or replacing O-Rings, assemble Nailer and connect to power
supply.
Replacing O-Rings
Use Texaco Molytex® EP 2 Grease or equivalent. Do not use greases that cause O-
Rings to swell. The use of these types of greases may prevent Nailer from operating
properly.
NEVER USE OIL FOR LUBRICATION!
