These tools are built for ease of maintenance. A few simple details will
assure trouble-free operation and long tool life. Anyone who uses or
maintains the tool must read the safety and maintenance instructions.
Study the schematic drawing before starting any repairs on the tool.
Air-operated tools must be inspected periodically, and worn or broken
parts must be replaced to keep the tool operating safety and efficiently.
Also the item on the maintenance chart must be checked often.
! COLD WEATHER CARE
When temperatures are below freezing, tools should be kept
warm by any convenient, safe method. If this is not possible, the
following procedure should be used to warm up the tool parts.
• Reduce the regulated air pressure to 30 psi.
• Remove all fasteners from the tool.
• Collect an air line and blank fire the tool. The reduced air
pressure will be enough to free-fire the tool. Slow speed operation
tends to warm up the moving parts. Slowing up the piston helps
bumper and the O-rings to become springy.
Never free-fire the tool at high pressure.
Once the tool is warmed up, readjust the regulator to the proper
•
working pressure and reload the tool.
Tool operators working outdoors or in unheated areas in
•
extremely cold temperatures.
Use recommended air tool oil with antifreeze in the lubricator.
