Operation & Parts Manual
1/2" Impact Wrench

Installation

Always use clean dry air. Excessive moisture and dirt will
greatly reduce the life of any air motor. We recommend the
installation of an in-line filter-regulator-lubricator as close to
the tool as possible.
A 3/8" air hose is required up to a length of 8 ft. If more length
is required a 1/2" air hose should be connected to the 3/8"
hose to ensure the tool has the necessary air supply. Be sure
all hoses and fittings are the correct size and tightly secured.
Before the tool is connected to the air supply, clear the air
hose of accumulated dust and moisture. Before removing a
tool for service or changing sockets, make sure the air line is
shut-off and drained of air. This will prevent the tool from
operating if the throttle is accidentally engaged.

Operation

This Husky 1/2" impact is supplied with an internal power
regulator, this tool may be adjusted by rotating the regulator
valve (Ref. No. 14), until desired output is achieved. The
numbers 0 through 4 on the regulator are only for reference and
do not denote a specific power output. Turn clockwise to zero
for less power and counterclockwise to four for maximum power.
Push reverse pin towards rear of tool for reverse direction.
Power is regulated in both forward and reverse direction.
Once a bolt or fastener is seated, impacting for longer than
five seconds will cause excessive wear and damage to the
impacting mechanism. If it takes longer than five seconds to
tighten your bolt or fastener, we recommend the use of a
larger size impact wrench.
Only use sockets designed for impact tools. Using hand
tool sockets can be hazardous and may result in personal
injury. Always check accessories for wear, cracks and
other defects before use.
Recommended Air Line Set-Up
Maintenance
Lubrication
An automatic in-line filter-regulator-lubricator is recom-
mended 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 approxi-
mately 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 Husky air tool oil or any other
high grade turbine oil containing moisture absorbents, rust
ng agents and an EP (extreme
inhibitors, metal wetti
pressure) additive.
