Lubrication
An automatic in-line filter-regulator-lubricator 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 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. 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 at that time. 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.
Recommended 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.
