MAINTAINING THE PNEUMATIC TOOL

When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.

CAUTION: Pusher spring (constant force spring). Caution must be used when working
with the spring assembly. The spring is wrapped around, but not attached to, a roller. If
the spring is extended beyond its length, the end will come off the roller and the spring
will roll up with a snap, with a chance of pinching your hand. Also the edges of the spring
are very thin and could cut. Care must also be taken to insure no permanent kinks are
put in the spring as this will reduce the springs force.

REPLACEMENT PARTS:

B&C Eagle replacement parts are recommended. Do not use modified parts or parts which will not give
equivalent performance to the original equipment.

ASSEMBLY PROCEDURE FOR SEALS:

When repairing a tool, make sure the internal parts are clean and lubricated. Use a small amount of oil on all
moving surfaces and pivots. After reassembly add a few drops of oil through the air line fitting before testing.

AIR SUPPLY-PRESSURE AND VOLUME:

Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of
undersized 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.

CAUTION: If the tool does not work as it should, contact a B&C Eagle service center immediately.
