Impact Wrench
INSTRUCTION MANUAL
This product is designed for installing and removing threaded
fasteners in wood, metal and plastic. No other use permitted.
For professional use only.
Air Supply Requirements
1. Supply tool with 90 psig (6.3 bar) of clean, dry air. Higher
pressure drastically reduces tool life.
2. Connect tool to air line using pipe, hose and tting sizes
shown in the diagram below.
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 6 oz. (177ml) of
SAE #30 oil or equivalent.
Operation
1. The intended use of this impact wrench is with impact rated
sockets operating upon threaded fasteners. To operate,
pull trigger on handle. To operate in forward rotation, turn
reverse valve toward forward arrow position. To operate in
reverse, turn valve toward reverse arrow position.
2. This impact wrench is equipped with a regulator to enable
adjustment of output power.
Maintenance
1. After rst year, 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:

Noise & Vibration Declaration*
Sound pressure level 110 dB(A) impacting, uncertainty 3
dB(A), in accordance with ISO
15744-2002. For sound power, add 11 dB(A).
Vibration value 7.6 m/s2, re. ISO 8662-7.
For making estimates of daily vibration exposures, useful
information may be found in CEN/TR 15350: 2006,
“Mechanical vibration - Guideline for the assessment of
exposure to hand-transmitted vibration using available
information including that provided by manufacturers of
machinery”
*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 reecting the actual
exposure, in an individual risk assessment in a work place
situation over which we have no control.

WARNING
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.
SAFETY INSTRUCTIONS
DO NOT DISCARD - GIVE TO USER
The goal of Chicago Pneumatic Tool Co. LLC is to produce tools
that help you work safely and ef ciently. 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  ttings.
 Do not use quick disconnect couplings at tool. See
instructions for correct setup.
 Whenever universal twist couplings are used, lock pins must
be installed.
 Do not exceed maximum air pressure of 90 psi/6.3 bar or as
stated on tool nameplate.
Entanglement Hazards
 Keep away from rotating drive.
 Do not wear jewelry or loose clothing.
 Scalping can occur if hair is not kept away from the tool and
accessories.
 Choking can occur if neckwear is not kept away from the 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).
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
speci c 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. 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).
 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 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  lter out microscopic particles.
Additional Safety Topics
 This tool and its accessories must not be modi ed.
 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.
