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:

Haussmann 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 Parker "O"-LUBE
or equivalent on all "O"-rings. Coat each "O"-ring with "O"-LUBE 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 SUPPLY-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.
