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 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 the
above figure.
The air inlet used for connecting air supply has standard 3/8" NPT.
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet). Minimum hose diameter should be 1/2" 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.
LUBRICATION
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.
OPERATION
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. This impact wrench is rated
at 3/4" SAE bolt size. Rating must be downgraded for spring
U bolts, tie bolts, long cap screws, double depth nuts, badly rusted
conditions and spring fastener, as they absorb much of the impact
power. When possible, clamp or wedge the bolt to prevent spring
back.
Soak rusted nuts in penetrating oil and break rust seal before
removing with impact wrench. If nut does not start to move in three
to five seconds, use a larger size impact wrench. Do not use impact
wrench beyond rated capacity as this will drastically reduce tool life.
The reversing valve is used to change the direction of the tool.
When the valve is out, the tool is in forward or right hand direction.
When the valve is pushed in, the tool is in reverse or left hand
direction.
NOTE: Always turn off the air supply, drain hose of air pressure
and detach tool from air supply before installing, removing or
adjusting any 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 condition absorbs energy and reduces power.
NOTE: During operation, safety goggles must always be worn
to guard against flying debris (users and bystanders).
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic action.
Reduced compressor output, excessive drain on the air line, 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.
