ACCESSORIES ASSEMBLY
L
Every three weeks clean the motor by
introducing naphtha (~25cc) through the
air inlet, while keeping the trigger pressed;
then running the wheel gun clockwise and
anticlockwise. After the inside washing,
repeat the previous operation with oil for
air tools (~5cc). These operations must be
performed in a suitably equipped working
environment, complete with extraction
equipment for nebulised particles. Use
personal protective equipment.

Use only genuine spare parts and authorized
service organizations.

tools, make use of the attached exploded
drawing with the list of spare parts.
L
Indicate the parts most subject to wear,
to be dismantled and checked at regular
intervals, as well as a list of malfunctions, if
any, and the corrective action.
L
If the tool is left unused for long periods
we recommend putting some oil into
the air inlet and letting it run for a few
seconds before putting it away. In this
way the internal components will remain
lubricated.
L
At regular intervals supply it with the
addition of lubricant ( view figure Fig.1 ), in
order to keep the appliance efficient and to
extend its service life.
