Declaration of noise and vibration emission
(See page 36).
All values are current as of the date of this
publication. For the latest information please visit
www.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, the workpiece and the
workstation design, as well 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.
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 http://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.

DISASSEMBLY AND REASSEMBLY
INSTRUCTIONS
Disconnect the machine from the
compressed air supply. Remove all
accessories.
Disassembling the turbine (see gure 2):
● Hold the housing (11) in one hand and extract
the turbine assembly by pulling the pinion
(31) or the coupling fork (22).
● Position a at wrench on the ats of the
pinion (31) or of the coupling fork (22), then
unscrew the governor (13).
Do not dismantle the governor, as it is an
integral assembly.
Disassemble the turbine (see gure 3):
● Clamp the rotor slightly in a vice tted with
lead jaws, then unscrew the pinion (31) or the
coupling fork (22).
● Using a mallet, tap on the rotor (18) ends to
extract the ball bearings (14-21).
Reassembling the turbine:
● Proceed in reverse order with respect to
disassembly.
Be careful with the direction for
assembling the vanes.
● Apply a small quantity of "Loctite 222" on the
thread of the governor (13) before tightening
it to a 1.4 N.m. torque.
● Be careful with the direction for assembling
the cylinder, align the lugs of the rear end
plate (15) with the cylinder (16) throttle.
Assembling the complete output shaft:
Be careful with the direction the nut (32)
is tted, with the cylindrical mark on gear
side.
● Apply a small quantity of "Loctite 243" on the
nut (32) thread and tighten the nut on the
shaft (34, 41 or 42) to a torque of 5 N.m.
● Before reassembling the complete output
shaft in the angle housing (30), lubricate the
gear (Amount of grease: 1 gramme).
