INSPECTION, MAINTENANCE, AND CLEANING

1.

Inspect the air supply Screen that is located in the Inlet Plug (47) before each
use, and clean or replace as necessary.  Dirt and water in the air supply Screen
are major causes of pneumatic tool wear.  Use a filter in the compressed air
system for better performance and longer tool life.  The filter must have adequate
flow capacity for the specific application.

2.

Clean the external parts of the Nailer with a clean cloth and mild detergent or
non-flammable solvent.  Then, dry.

3.

Store the tool in a clean, dry, safe location out of reach of children.

4.

      CAUTION:  All maintenance, service, or repairs not listed in this manual
are only to be attempted by a qualified service technician.
