Operation

This power tool is supplied from single-phase alternating
current mains only. It is double insulated according to EN
60745-1, IEC 60745 and can be connected to grounded
or not grounded sockets. This power tool is radio sup-
pressed in compliance with EMC Directive.
This power tool is designed for rough and fine grinding
concrete and rock material with the purpose of refurbish-
ing before laying plaster and protective coating. The ma-
chine is designed for dry grinding only.
PRIOR TO INITIAL OPERATION
▪ Make sure the power supply voltage corresponds to
the value indicated on the name plate with technical
data of the tool.
▪ Always check the position of ON/OFF switch. The
power tool must be connected to the power supply
socket only when this switch is in OFF position.
▪ Make sure that the cord and the plug are in order. If the
replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order
to avoid a safety hazard.

WARNING: Always switch off and unplug the
power tool prior to any adjustment, servicing or main-
tenance.
▪ When using diamond cutting discs, pay attention that
the direction-of-rotation arrow on the diamond cut-
ting disc and the direction of rotation of the machine
(see direction-of-rotation arrow on the machine head)
agree.
▪ Always use the auxiliary handle and hold the machine
firmly with both hands for maximum control over
torque reaction or kickback upon starting. (Fig. 1)
SWITCHING ON - SWITCHING OFF
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
1. To switch on: Push the slider of the switch slider (7)
forward until its front end sags thus fixing itself. (Fig. 2)
2. To switch off: Press the back lifted end of the switch
slider (7) and release it in order to move back in its
initial position. (Fig. 3)
ELECTRONIC DEVICE
This power tool is equipped with an electronic device
featuring:
▪ Safety upon mains drop-out: In case of mains drop-
out (or temporary drop-out for time t > 0,5 s), when the
ON/OFF switch is in ON position, the machine should
not operate after supply recovering. To start operating
the machine, first switch off and then switch on the
lever of ON/OFF switch.
▪ Soft start and overload protection: This feature en-
sures starting without jerks and prevents origination
of supply voltage fluctuations;
▪ Virtually constant speed under wide range of loads;
▪ Brief overload protection: Upon major brief overloads
a current overload protection actuates, which reduces
harshly the rotation speed. To resume normal opera-
tion withdraw the machine from the material.
▪ Thermal overload protection: Upon minor long over-
loads, the thermal overload protection actuates. The
electronic device switches the machine off before the
temperature reaches critical value and the machine
switches from operating to safety mode with lower
motor speed. The normal operation is disabled. In
safety mode the motor rotates with lower speed to
facilitate cooling, but the machine is DISABLED. After
cooling down for 3-5 minutes the machine can be op-
erated again. To resume operation switch the trigger
off and on again.
WHEEL GUARD
The wheel guard (2) must always be mounted on the
machine!
