POWER MANAGEMENT SYSTEM AND TOOL OPERATION
This tool includes a power management system that allows the
operator to adjust the amount of output power in the clockwise
direction (forward). There is no power management system
present in the counter-clockwise direction (reverse). To adjust
the power output in the forward direction, turn the dial shown
below left or right in the desired power direction. Power output
is indicated by enlarging black swoosh on back housing. Lowest
power setting indicated by thin swoosh area with highest power
setting being thickest swoosh area.
The Power management system is only for reference and do
not act as specific power settings. This tool includes a tip valve
variable speed trigger design that further allows the operator to
reduce the power output.
This tool is an impacting tool and not a torque meter. When
specific torque is required, it must be checked with a torque
meter after fitting the fastener with the Impact.
FEATURES
• Customize dBA with exclusive removable muffler plate.
• Work easily with one-hand push button design and an overall weight of just 4.6 lbs
• Power through your day with rear housing power adjustment
• Take full control with variable speed trigger
• Get a grip with textured housing and durable ergonomic design
AIR SUPPLY
Tools operate on a wide range of air pressures. It is recommended
that air pressure measures 90 psig at the tool with the trigger fully
depressed and no load applied to the tool. Higher pressure (over
90 psig; 6.2 bar) raises performance beyond the rated capacity of
the tool, which will shorten tool life and could cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in
the air line will cause damage to the tool. Drain the water from
air lines and compressor prior to running tool. Clean the air inlet
filter screen weekly. The recommended hookup procedure can
be viewed in FIG. 1.
The air inlet used for connecting air supply has standard 1/4" NPT.
Line pressure should be increased to compensate for unusually
long air hoses (over 25 feet). Minimum hose diameter should be
3/8" I.D. and fittings should have the same inside dimensions and
be tightly secured.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,

Drain Daily
If a fastener does not move within five seconds, use a larger size
Impact. Do not use Impact Wrench beyond rated capacity, as this
can drastically reduce the tool life.
Always turn off the air supply, drain hose of air pressure and
detach tool from air supply before installing, removing or
adjusting any part or accessory on this tool, or before performing
any maintenance on this tool.
NOTE: Actual torque on a fastener is directly related to joint
hardness, tool speed, condition of socket and the time the tool is
allowed to impact.
Use the simplest possible tool-to-socket hook up. Every
connection absorbs energy and reduces power.
NOTE: During operation, safety goggles must always be worn to
guard against flying debris (users and bystanders).
moisture or restrictions in air pipes or the use of hose connections
of improper size or poor conditions may reduce air supply. Grit or
gum deposits in the tool may cut power and may be corrected
by cleaning the air strainer and flushing out the tool with gum
solvent oil or an equal mixture of SAE #10 and kerosene. If outside
conditions are in order, disconnect tool from hose and take tool to
your nearest authorized service center.
LUBRICATION AND MAINTENANCE
Lubricate the air motor daily with high quality air tool oil. If no air
line oiler is used, run 1/2 oz. of oil through the tool. The oil can
be squirted into the tool air inlet or into the hose at the nearest
connection to the air supply, then run the tool. A rust inhibitive oil
is acceptable for air tools.
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation.
The exhaust port must be covered with a towel before applying
air pressure to prevent serious injury.
