Lubrication
Recommended
An in-line filter-regulator-lubricator
(fig 1)
is recommended as it increases tool life
and keeps the tool in sustained operation.
The in-line lubricator should be regularly
checked and filled with air tool oil. Proper
adjustment of the in-line lubricator is
performed by placing a sheet of paper
next to the tools exhaust ports and holding
the throttle open approximately 30
seconds. The lubricator is properly set
when a light stain of oil collects on the
paper.

Lubricants
Use air tool oil or any other high grade
turbine oil containing moisture absorbent,
rust inhibitors, metal wetting agents and
an EP (extreme pressure) additive. See
Figure 3 for location/air inlet.
Excessive amounts of oil should be
avoided. In the event that it becomes
necessary to store the tool for an
extended period of time (overnight,
weekend, etc.), it should receive a
generous amount of lubrication through
the air inlet (Figure 3). The tool should be
run for approximately 30 seconds to
ensure oil has been evenly distributed
throughout the tool. The tool should be
stored in a clean and dry environment.

4. Air hose leaks
5. Pressure drops
4. Tighten and seal hose fittings if leaks are
found.
5a. Be sure the hose is the proper size.
Long hoses or tools using
large volumes of air may require a hose with
an I.D. of 1/2" or larger depending on the
total length of the hose.
5b. Do not use multiple number of hoses
connected together with quick connect
fittings. This causes additional pressure
drops and reduces the tool power. Directly
connect the hoses together.

NOTE: Separators only work properly when
