INSTRUCTION MANUAL
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.
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 3/4 oz.
(22ml) of SAE#30 oil or equivalent.
Operation
This impact wrench is equipped with a regulator to
enable adjustment of output power. Turn the regulator
knob counter-clockwise for maximum power,
clockwise to reduce power.
Maintenance
1. Disassemble and inspect air motor and impacting
clutch every three (3) months if the tool is used
every day. Replace damaged or worn parts.
2. High wear parts are underlined in the parts list.
3. To keep downtime to a minimum, the following
service kits are recommended:
Tune-Up Kit CA147716
(Incl: 7, 41, 62, 66, 68, 106, 107, 115 & 127)

SAFETY INSTRUCTIONS
To reduce risk of injury, everyone using, installing, repairing,
maintaining, changing accessories on, or working near this tool must
read and understand these instructions before performing any such
task.
DO NOT DISCARD - GIVE TO USER
The goal of Chicago Pneumatic is to produce tools that help
you work safely and efficiently. The most important safety
device for this or any tool is YOU. Your care and good
judgment are the best protection against injury. All possible
hazards cannot be covered here, but we have tried to
highlight some of the important ones.
For Additional Safety Information Consult:
!Your employer union and/or trade association.
!US Department of Labor (OSHA); www.osha.gov; Council
of the European Communities europe.osha.eu.int.
!“Safety Code For Portable Air Tools” (B186.1) available
from: www.ansi.com
!“Safety Requirement For Hand-Held Non-Electric Power
Tools” available from: European Committee for
Standardization, www.cenorm.be
Air Supply And Connection Hazards
!Air under pressure can cause severe injury.
!Always shut off air supply, drain hose of air pressure and
disconnect tool from air supply when not in use, before
changing accessories or when making repairs.
!Never direct air at yourself or anyone else.
!Whipping hoses can cause serious injury. Always check for
damaged or loose hoses and fittings.
!Do not use quick disconnect couplings at tool. See
instructions for correct set-up.
!Whenever universal twist couplings are used, lock pins
must be installed.
!Do not exceed maximum air pressure of 90 psi (6.2 bar) or
as stated on tool nameplate.
Entanglement Hazards
!Keep away from rotating drive.
!Do not wear jewelry or loose clothing.
!Choking can occur if neckwear is not kept away from tool
and accessories.
!Scalping can occur if hair is not kept away from tool and
accessories.
!Avoid direct contact with accessories during and after use.
Gloves will reduce the risk of cuts or burns.
!Use only proper accessory retainers (see parts list). Use
deep sockets wherever possible.
Projectile Hazards
!Always wear impact-resistant eye and face protection when
involved with or near the operation, repair or maintenance
of the tool or changing accessories on the tool.
!Be sure all others in the area are wearing impact-resistant
eye and face protection.
!Even small projectiles can injure eyes and cause blindness.
!Use only impact wrench sockets and accessories in good
condition. Sockets in poor condition or hand sockets and
accessories used with impact wrenches can shatter.
!Always use the simplest hook-up possible. Long, springy
extension bars and 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.
Additional Safety Topics
!This tool and its accessories must not be modified.
!This tool is not recommended for use in explosive
atmospheres.
!Operators and maintenance personnel must be physically
able to handle the bulk, weight and power of the tool.
!For professional use only.
