LUBRICATION
This tool is fitted with blades which can
operate without lubricated air. However,
a small amount of oil allows the tool to
provide full power and lengthens its life.
The use of dry air with no trace of oil may
reduce the life of blades.
MAINTENANCE INSTRUCTIONS
The use of spare parts other than those
originally supplied by the manufacturer
may result in a drop in performance or
in increased maintenance and level of
vibration and in the full cancellation of the
manufacturer's liability.
To obtain maximum efficiency from the
pneumatic tool, preserve its features
and avoid repeated repairs, a routine
inspection and repair programme
are recommended at least every 500
hours, the intervals between the various
inspections depending on the amount of
exertion on the power tool.
When disposing of components,
lubricants, etc... ensure that the relevant
safety procedures are carried out.
The rotor blades in this tool have a PTFE
content. The normal health and safety
recommendations concerning PTFE must
be observed when handling these rotor
blades.
● Do not smoke.
● Motor components must be washed
with cleaning fluid and not blown clear
with an air line.
● The silencer must be replaced when
dirty, do not clean and re-use.
● Wash hands before commencing any
other activity.

DISASSEMBLY AND REASSEMBLY
INSTRUCTIONS
See page 4.
Disconnect the machine from the
compressed air supply.
Remove all accessories.
Disassembling the turbine
See figure 3.
● Hold the housing (11) in one hand and extract
the turbine assembly by pulling the pinion (31)
or the coupling fork (22).
● Position a flat wrench on the flats 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.
Remove the turbine
See figure 4.
● Clamp the rotor slightly in a vice fitted with
lead jaws, then unscrew the pinion (31) or the
coupling fork (22).
● Using a mallet, tap gently on the ends of the
rotor (18) to extract the bearings (14-21).
Reassembling the turbine
● Proceed in reverse order with respect to
disassembly.
Be careful with the direction for
assembling the blades.
● Apply a small quantity of "Loctite 222" on the
thread of the governor (13) before tightening it
to a 1.4 Nm. torque.
● Be careful with the direction for assembling
the cylinder and check that the lugs of the
rear plate (15) are in line with the cylinder (16)
inlet.
Assembling the output shaft assembly
Be careful with the direction for fitting
the nut (32), checking that the cylindrical
mark is on pinion side.
● Apply a small quantity of "Loctite 270" on the
thread of the nut (32) and tighten it onto the
shaft (34) to a torque of 11 N.m.
● Before reassembling the output shaft
assembly in the angle housing (30), lubricate
the pinion (Amount of grease: 1 gram).
