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.
Lubricating the bevel gear. Amount of
grease: 1 gramme. Recommended
grease: 6159901480 (Qty: 1Kg). The
use of any other lubricant, in any other
amount, will shorten the life and impair
the operation of angle pinions.

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.
