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 air tool 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.
For gearing and clutch, use grease containing molybdenum disulfide such as Chicago
Pneumatic CA131898 [14 oz (395 g)]. Grease clutch every 12,000 screws.
Torque Adjustment
Rotate ring (5) to expose clutch adjustment. Insert a #1 Phillips screwdriver and turn counter-
clockwise to increase torque. Turn clockwise to decrease torque.
Maintenance
1.
Disassemble and inspect air motor and gears every three (3) months if the tool is used every
day.
2.
Replace damaged or worn parts.
3.
Use a good grade gear grease.
4.
High wear parts are underlined in the parts list.
Noise & Vibration Declaration*
2
Vibration value 12.0 m/s , re. ISO 8662-7.
Disassembly/Assembly
Clutch housing (6) has left-hand thread. Motor assembly - Pressing on the inner race, assemble
the upper rotor bearing (28), upper end plate (29), to the rotor shaft (30), until the rotor binds on
the upper end plate. Tap on the end of the rotor using a soft faced mallet until .0015 in.
clearance is established between the end plate and the face of the rotor. Assemble blades (31)
and liner (32). Press lower rotor bearing (28) into the spacer (27), pressing on the outer race.
Assemble the spacer, lower end plate (29) and bearing on the splined end of the rotor by
pressing on the inner race. Press carefully until a slight drag is felt when moving the liner
between end plates.
*These declared values were obtained by laboratory type testing in compliance with the stated standards and are 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 93.9 dB(A) in accordance with Pneurop 8N-1. For sound power, add 10
dB(A).

!
Even small projectiles can injure eyes and cause blindness.
!
Do not use hand sockets as they can shatter. Use only power or impact
sockets in good condition.
!
Always use the simplest hook-up possible. Long, springy extension bars
and adapters absorb power and could break. Use deep sockets where
possible.
!
Never operate the tool off of the work. It may run too fast and cause the
accessory to be thrown off the tool.
Workplace Hazards
!
Slip/Trip/Fall is a major cause of serious injury or death. Be aware of
excess hose left on the walking or work surface.
!
Maintain a balanced body position and secure footing.
!
High sound levels can cause permanent hearing loss. Use hearing
protection as recommended by your employer or OSHA regulation (see
29 CFR part 1910).
!
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 tool and consult a physician.
!
Always support the tool’s handle securely, in the direction opposite of the
spindle rotation, to reduce the effect of sudden torque reaction during
final tightening and initial loosening.
!
An additional support handle or absorption bar may be needed to resist
torque reaction. Absorption bars must be positioned correctly to avoid
injury.
!
Proceed with care in unfamiliar surroundings. Be aware of potential
hazards created by your work activity.
!
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.
