When working on pneumatic tools, note the warnings in this manual and use extra care evaluating tools with problems.
Disconnect the air supply and empty the magazine when inspecting or maintaining the tool.
REPLACEMENT PARTS
Use only genuine parts from the manufacturer or distributor. Do not use modified parts or parts which will not give
equivalent performance to the original equipment. Tighten all screws. Keep contact arm moving smoothly.
ASSEMBLY PROCEDURE FOR SEALS
When repairing a tool, make sure the internal parts are clean and lubricated. Use O-Ring lubricant on all O-Rings. Coat
each O-Ring with O-Ring lubricant before assembling. Use a small amount of oil on all moving surfaces and pivots. After
reassembly add a few drops of Air Tool Lubricant through the air line fitting before testing.
AIR PRESSURE AND VOLUME
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize
fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from receiving
an adequate volume of air, even though the pressure reading is high. The results will be slow operation, misfeeds or
reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from the tool to the supply
source for restrictive connectors, swivel fittings, low points containing water and anything else that would prevent full
volume flow of air to the tool.
Worn drivers can cause poor driving quality or loss of power:
Worn or chipped driving tips will affect the fastener drive, give symptoms of bent and incompletely driven fastener, and
damaged fastener heads.
Contact a qualified distributor or agent to replace worn driver.
