ON/OFF SWITCH
WARNING: To reduce the risk of injury, make sure the polisher is not resting on the workpiece when
the switch is turned on.
To turn the polisher on, push the lever of the switch (2) towards the body of the tool; if the polisher is to
be locked in ON position, press button (9) at the same time and keep it pressed while releasing lever, thus
locking the switch.
To turn the polisher off, release the lever or, if locked in ON position, push the lever to release the lock button.
ELECTRONIC SPEED CONTROL
The polisher electronic speed control supplies the following features.
Speed Adjustment
The speed can be adjusted in two ways: by means of the variable actuation switch (2), by means of the
adjustment wheel fitted on the upper part of the machine (3). Adjustment by means of the wheel (3) affects
the adjustment made using the variable actuation switch (2), determining the maximum speed of the motor.
The speed must be selected according to the characteristics of the pads and those of the material to be
machined.
Speed compensation
In case of overloading the polisher, the electronic speed control will compensate and maintain the selected
speed at a safe level. Exceeding this overload level may result in strong vibrations and tool overtemperature.
Starting acceleration ramp
To avoid kickback effect and compound splattering, the electronic speed control always supplies a smooth
starting acceleration ramp when the tool is turned on.
Accidental re-start protection
In case of a sudden lack of main power supply, the electronic speed control prevents the re-start after the
power supply restoring if the main switch is turned on. The polisher must be turned off and on again pushing
the lever of the switch (2) toward the body of the tool.
BEFORE STARTING THE POLISHER
Ensure that:
• The power supply conforms with the characteristics of the tool (see tab “Minimum Gauge for Cord Sets”)
• The power supply cable and plug are in perfect condition
• The ON/OFF switch works properly though with the power supply disconnected
• All the parts of the tool have been assembled in the proper manner and that there are no signs of damage
• The ventilation slots are not obstructed
FAILURE TO START
Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the
outlet. Also, check for blown fuses or open circuit breakers in the line.
MAINTENANCE
Maintenance and cleaning of the inner parts, like brushes, ball bearings, gears etc. or others,
must be
carried out only by an authorized customer service workshop.
