TOOL MAINTENANCE
Refer to "Operator Safety Instructions" section of this manual before servicing the tool.

VISUAL INSPECTION

Daily visual inspection of the tool should be made before attaching air supply hose.
• Check for:
• Smooth trigger and work contact element movement.
• All screws are tight.
• Excessively worn or cracked handle.
• Damaged or other excessively worn parts.
• NEVER USE A TOOL WITH DAMAGED OR MISSING PARTS.
CLEANING
The external tool parts should be cleaned daily as follows:
• Disconnect air supply hose from tool.
• Remove fasteners.
• Wipe clean with rag.
Clean tool exterior with mild solvent. Make sure all excess solvent has been wiped off. Never completely immerse
tool in any solvents, especially highly volatile solvents such as gasoline, toluene, benzene, etc.. Immersion into
solvent or the use of volatile solvents for cleaning can damage the O-rings which will cause tool to malfunction.
NOTE: It is extremely important that all dirt and foreign material be removed from around the work contact
element and it's spring. Any dirt which prevents the movement of the work contact element will cause the tool to
be unsafe.
LUBRICATION
The following lubricants are recommended for the air line and tool:
• Above 32 degrees Fahrenheit, use a non-detergent S.A.E. No. 20 weight oil.
• Below 32 degrees Fahrenheit, use a mixture of one part non-detergent S.A.E. No. 10 weight oil to three
parts ethylene glycol automotive antifreeze, certified as being compatible for use with aluminum.
It should not contain any "anti-leak" additives.
• Placing a few drops of non-detergent oil in the tool air inlet before each use is beneficial. It is intended to
supplement an air line lubricator, not to replace it's use.
• Never use detergent oils. Detergent-type oils can deteriorate o-rings in the tool which can cause a tool to
malfunction.
• Clean work contact element, then apply a thin coating of light weight grease to the slide guides on the work
contact element.
