regulator are only for reference only and do not denote a

Regulator Valve
Once a bolt or fastener is seated, impacting for longer
than five (5) seconds
will cause excessive
wear and
damage to the impacting
If it
takes longer than five seconds to tighten or loosen your
bolt or fastener,
we recommend
the use of a larger size
An in-line filter-regulator-lubricator
(fig 1) is recommended
as it increases toot life and keeps the toot in sustained
operation. The in-line lubricator should be regularly
checked and filled with air toot 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. The toot should be run for approximately 30
seconds to ensure oil has been evenly distributed
throughout the toot. The tool should be stored in a clean
and dry environment.
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.
Impact clutch lubrication:
The oil reservoir in the anvil
housing should be checked every 40 hours of operation
Remove the oil plug from the housing and hold tool so
the the oil port is lower than the anvil housing. Drain oil.
Meausure and refill with approximately
1 oz. (30 rot) of
SAE 30 weight oil. Never over fill the anvil.
