Lubrication
An automatic in-line fllter-regu|ator-lubdcator is recom-
mended as it in.eases tool life and keeps the tool in
sustained operation, The in-line lubricator should be
chedr.edregularly and filled with air tool oil. Proper
adjuaimenl of the in-line lubricator is performed by
placinga sheet of paper next to the exhaust ports and
holding the throttle open approximately30 seconds. The
lubricatoris properly set when a light stain of oll collects
on the paper. Excessive amountsof oil shouldbe
avoided.
In the event that it becomes necessary to store the tool for
an extended periodof time (overnight,weekend, etc.), it
shouldreceive a generous amount of lubricationat that
time. The tool should be run for approximately30 sec-
onds to ensure oil has been evenly distributedthroughout
the tool. The tool should be stored in a dean and dry
environment.
Recommended lubricants: Use air tool oilor any other
high grade turbine oil containingmoisture absorbent, rust
inhibltom,metal wetting agents and an EP (extreme
pressure) additive.
