ACCESSORIES ASSEMBLY
L
Clockwise rotation (tightening): Slide “T” to
the left the rotation reverse shaft and push
“P” the trigger
(view figure Fig.3-A and
figure Fig.3-C
).
L
Counter clockwise rotation (loosening):
Slide “T” to the right the rotation reverse
shaft and push “P” the trigger (

HANDLING
L
Power adjustment: Rotate the regulator
level to the desiderate level indicator (
view
figure Fig.5
). The power setting indicators
are for reference and don’t indicate a
specific power.
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.
L
Use only genuine spare parts and authorized
service organizations.
L
Do not carry out maintenance with improper
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.
L
Clean the supply filter and drain off the
condensation at regular intervals (
view
figure Fig.1
).
L
Every 6 months make the maintenaince on
the impact wrench with grease in the hammer
mechanism.
1. Secure the machine with a vise, with axis
the hammer cage in a vertical position
(
view figure Fig.5-A
).
2. With an Allen wrench, unscrew the screws,
therefore the washers will come out. Take
out the complete cover and remove the
gaskets (if presents), the screws and the
washers (
view figure Fig.5-B
).
3. Clean with a rag and lubricate with the
brush (the grease contained in service kit
included) the visible parts of the impact
mechanism (
view figure Fig.5-C
).
4. Put the new gasket (included in service
kit). Replace the cover, the new washers,
and screw use a dynamometric wrench
the new screws (included in service kit)
(
view figure Fig.5-D
).
