WARNING
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm. Some examples of
these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed
to filter out microscopic particles.

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 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.
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 ratchet is rated at 1/4" USS bolt size. Rating must be down
graded for spring U bolts, tie bolts, long cap screws, double depth
nuts, badly rusted conditions and spring fasteners as they absorb
much of the impact power. When possible, clamp or wedge the bolt
to prevent springback.
Soak rusted nuts in penetrating oil and break rust seal before
removing with impact ratchet. If nut does not start to move in three
to five seconds use a larger size impact ratchet. Do not use impact
ratchet beyond rated capacity as this will drastically reduce tool life.
The reverse button is used to change the direction of the tool. When
the button is turned to the left, the tool is in a forward or right hand
direction. When the button is turned to the right, the direction is in
reverse or left hand direction.
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: 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.
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.
