Air Supply Requirements
1. Supply tool with 90 psig (6.2 bar) of clean, dry air. Higher pressure drastically
reduces tool life.
2. Connect tool to air line using pipe, hose, and fitting sizes shown in the diagram on
page 12.
Lubrication
1. Use an air line lubricator with SAE #10 oil, adjusted to two (2) drops per minute. If
an air line lubricator cannot be used, add air motor oil to the inlet once a day.
2. Check clutch oil once each month. Use 2.0 oz. (59 ml) of SAE #30 oil or
equivalent.
Operation
This impact wrench is equipped with a regulator to enable adjustment of output
power. Turn regulator knob counterclockwise for maximum power, clockwise to
reduce power. When the tightening nuts not requiring critical torque values, run
nut up snug and then tighten an additional one-quarter to one-half turn.

not adequate for use in risk assessments. Values measured in individual work places may be higher than the
declared values. The actual exposure values and risk of harm experienced by an individual user are unique and
depend upon the way the user works, the workpiece and the workstation design, as well as upon the exposure time
and the physical condition of the user. We, Chicago Pneumatic, cannot be held liable for the consequences of
using the declared values, instead of values reflecting the actual exposure, in an individual risk assessment in a
work place situation over which we have no control.
Sound pressure level 100 dB(A) in accordance with Pneurop 8N-1. For sound
power, add 10 dB(A).

adapters absorb impact power and could break. Use deep sockets wherever
possible.
!
Never operate the tool off of the work. It may run too fast and cause the accessory
to be thrown off the tool.
!
Serious injury can result from over-torqued or under-torqued fasteners, which
can break, or loosen and separate. Released assemblies can become
projectiles. Assemblies requiring a specific torque must be checked using a
torque meter.
Note: So-called "click" torque wrenches do not check for potentially dangerous
over-torque conditions.
Workplace Hazards
!
Slip/Trip/Fall is a major cause of serious injury or death. Beware of excess hose
left on the walking or work surface.
!
High sound levels can cause permanent hearing loss. Use hearing protection as
recommended by your employer or OSHA regulation (see 29 CFR part 1910).
!
Maintain a balanced body position and secure footing.
!
Be in control of the throttle at all times. Do not get caught between the tool and the
work.
!
Repetitive work motions, awkward positions and exposure to vibration can be
harmful to hands and arms. If numbness, tingling, pain or whitening of the skin
occurs, stop using the tool and consult a physician.
!
Avoid inhaling dust or handling debris from the work process which can be
harmful to your health. Use dust extraction and wear respiratory protective
equipment when working with materials which produce airborne particles.
!
Proceed with care in unfamiliar surroundings. Be aware of potential hazards
created by your work activity. This tool is not insulated for coming into contact with
electric power sources.
!
Some dust created by power sanding, sawing, grinding, drilling and other
construction activities contains chemicals known to the State of California to
cause cancer and birth defects or other reproductive harm. Some examples of
these chemicals are:
- Lead from lead based paints
- Crystalline silica bricks and cement and other masonry products
- And Arsenic and chromium from chemically-treated rubber
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 dust masks that are
specially designed to filter out microscopic particles.
