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.
After cleaning or changing the rotor or
the vanes, introduce 5 drops of oil (P.N.
6159900440) into the motor for the
complete lubrication of the mechanical
parts.
MAINTENANCE INSTRUCTIONS
Should the suction system get clogged,
remove the sanding pad and blow into the
dust exhaust pipe outwards.
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 2000
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.

(drawing C) and clamp the assembly in a vice
fitted with soft jaws.
● Remove the 4 screws (43) from the pad (41-
42).
● Loosen the screw (49), then remove the
counterweight (40) and the felt (36).
● Finally remove the lower clamp (35) from the
suction cap and extract the plate (38-39).
Disassembling and reassembling the turbine
● Remove the felt (36) from the shaft.
● Using the pin wrench (drawing D), loosen the
plug (30).
● Extract the turbine.
● Remove the O-Ring (25) and the circlip (20).
● Using a bearing extractor, remove the rear
end plate (22), pull out the cylinder, the rotor,
the vanes and the Woodruff key.
● Remove the front end plate (27) fitted with an
O-Ring (29), then remove the motor plug (30).
● Extract the ball bearing (21) from the rear end
plate (22) by means of the chuck (drawing F).
● Remove the felt (47).
● Using two screwdrivers (drawing B), pull
out the ball bearing from the shaft, then use
an extractor to remove the ball bearing (28)
before extracting the second felt (47).
● Clean and replace parts if necessary.
● Position the felt (47) on the shaft.
● Then use a shouldered chuck (drawing E)
to hang the ball bearing (28) to the eccentric
shaft (32) and put the second felt back on the
shaft before tightening the motor plug (30).
● Use the shouldered chuck (drawing E) to hang
the front end plate (27) to the ball bearing.
● Position the Woodruff key into its housing
(tight).
● Position the rotor (check direction of assembly
on drawing A) and make sure that the rotor
can slide freely on the shaft.
● Slip the vanes into the rotor and position the
cylinder on the front end plate, using the roll
pin.
