Declaration of noise and vibration emission
All values are current as of the date of this publication. For the
latest information please visit cp.com.
These declared values were obtained by laboratory type
testing in accordance with the stated standards and are
suitable for comparison with the declared values of other
tools tested in accordance with the same standards. These
declared values are not adequate for use in risk assessments
and values measured in individual work places may be higher.
The actual exposure values and risk of harm experienced by
an individual user are unique and depend upon the way the
user works, he workpiece and the workstation design, as well
upon the exposure time and he 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 situa ion over which we have no
control.
This tool may cause hand-arm vibration syndrome if its
use is not adequately managed. An EU guide to managing
hand-arm vibration can be found at www.pneurop.eu/uploads/
documents/pdf/PN3-02-NV_Declaration_info_sheet_0111.pdf
We recommend a programme of health surveillance to
detect early symptoms which may relate to noise or vibration
exposure, so that management procedures can be modied to
help prevent future impairment.

This product is designed for installing and removing threaded
fasteners in wood, metal and plastic. No other use permitted.

used, add air motor oil to the inlet once a day.
2. Use 0.25 oz. (7 g) of CP Pneu-Lube Synthetic Clutch
Grease 8940158455.
Operation
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,
push the reverse switch to the left. To operate in reverse
rotation, push the reverse switch to the right. This impact
wrench includes a power management system to enable
adjustment of output power in the forward direction. To
adjust the power, rotate the power regulator to #3 for
maximum power, to #1 for minimum 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.
