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.
