EXPOSURE TO
VIBRATION
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 of this class operate on a wide range
of air pres sures. It is recommended that air
pres sure of these tools mea sures 90 PSI at
the tool while running free. Higher pres sure
(over 90 psig; 6.2 bar) raises performance
beyond the rated capacity of the tool which
will short en tool life be cause of faster wear
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 air
tank daily. Clean the air inlet filter screen
on at least a weekly schedule. The rec om-
mend ed hookup pro ce dure can be viewed
in the above figure.
The air inlet used for con nect ing air supply,
has stan dard 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 di men sions and be tightly secured.
Operation
This ratchet wrench is rated at 3/8" 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 fas ten ers as they absorb much
of the impact power. When possible, clamp
or wedge the bolt to prevent springback.
Soak rusted nuts in pen e trat ing oil and
break rust seal before removing with ratchet
wrench. If nut does not start to move in
three to five sec onds use an impact wrench.
Do not use impact wrench be yond rated
ca pac i ty as this will dras ti cal ly reduce tool
life.
The forward/reversing button is used to
change the ro ta tion of the tool. When the
button is set to the right, the tool will turn
in a right hand ro ta tion. When the button
is set to the left, the tool will turn in a left
hand ro ta tion.
NOTE: Actual torque on a fastener is di rect-
ly related to joint hard ness, 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.
Troubleshooting
Other factors outside the tool may cause
loss of power or erratic action. Reduced
compressor output, ex ces sive 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 and the tool
continues to perform erratically, disconnect
tool from hose and take tool to your nearest
au tho rized service center.
Lubrication
Lubricate the air motor daily with quality
air tool oil. If no air line oiler is used, run
a teaspoon of oil through the tool. The oil
can be squirted into the tool air inlet or into
the hose at the nearest con nec tion to the
air supply, then run the tool. The amount of
oil to be used is 1/2 ounce. Overfilling will
cause a re duc tion in the power of the tool.
Grease ratchet housing and reverse button
through grease fittings as needed.
