This tools power regulator valve (fig. 2). Rotate regulaotor
until desired output is achieved. The settings on the
regulator are only for reference only and do not denote a
specific power output. Turn regulator to position with 1
being the least amount of power and 4 being for the most
amount of power.

Once a bolt or fastener is seated, impacting for longer
than five (5) seconds will cause excessive wear and
possible damage to the impacting mechanism. If it
takes longer than five seconds to tighten or loosen your
bolt or fastener, we recommend the use of a larger size
impact wrench.
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.
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 (fig 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.
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. (See Fig. 3 for location/air inlet).
Impact clutch lubrication: The tool reservoir in the anvil
housing is greased. No maintenance is required.
