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.
