fastening operation, as serious injury could result if the trip accidentally contacted
someone or something, causing the tool to cycle.

bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven, possibly causing injury.

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