6 Double insulation

To ensure maximum safety of the user, our tools are designed and
built to satisfy applicable European standards (EN standards). Tools
with double insulation are marked by the international symbol of
a double square. These tools must not be grounded and a two-wire
cable is sufficient to supply them with power. Tools are shielded in
accordance with EN 55014.
7 Use
The machine is designed for splitting, roughing and brushing met-
al and stone materials without the use of water.
The user bears full responsibility for the consequences of using the
tool for purposes other than the above.
8 Protective elements and their
assembly
The grinder may be used with mounted protective guard only!
Attention! Prior to handling the accessories, the power
supply cable has always to be disconnected from the
power source socket!
8.1 Protective guard
Loosen the fixing lever [7a]. Put the protective guard [8] on the
clamping collet [6]. The guide lug [15] must be inserted into the
groove on the clamping collet. Set the protective guard [8] to the
requested working position and fix the collet, using the fixing
lever [7a].

8.2 Additional handle

Special construction regulates the vibrations with auxiliary han-
dle [5]. Auxiliary handle can be screwed from the left or right side
of gearbox [4]. Some operations may require the handle screwed
to the top of gearbox.
9 Grinding or cutting wheel fixing
Attention! Prior to handling the accessories, the power
supply cable has always to be disconnected from the
power source socket!
Clean the bottom flange [11] and the clamping nut [9] as well as
the clamping surfaces of the grinding or cutting wheel. Place the
bottom flange [11] (by the recess out) on the spindle [12]. Place
the grinding [10a] or cutting wheel [10b]. The bottom flange re-
cess [11] must be inserted precisely into the grinding wheel [10a]
or the cutting wheel [10b] hole. Then put the clamping nut [9] on
the spindle [12] so that when fixing the grinding wheel [10a], the
clamping nut recess [11] must be faced towards the wheel and
when fixing the cutting wheel [10b], the clamping nut recess [11]
must be directed from the wheel!
Depress the lock spindle pin [13].
Attention! Use the lock spindle pin only if the spindle is at rest
and the grinder is de-energized.
Swivel the wheel /spindle, until the lock spindle pin [13] is engaged.
Tighten the clamping nut [9] firmly, using the wrench [14]. Prior to
start the grinder verify that the wheel does not rotate freely.
Attention! Prior to starting the grinder, verify that the wheel
does not rotate freely between the bottom flange/the auto-
balancer and the clamping nut.
10 Putting into operation
Check whether the data on the rating plate match with the real
power supply voltage. The tool intended for 230 V~ may be also
connected to 220/240 V~. Check whether the plug type corre-
sponds to the socket type.
10.1 Switching on- off
Push the safety lock-off lever [2] forwards to release the On/Off
switch lever [1]. At the same time, press the on-off switch lever [1]
to start the grinder and release it to stop.
10.2 Continuous operation
Push the safety lock-off lever [2] forwards to release the On/Off
switch lever [1]. At the same time, press the on-off switch lever [1]
and push the safety lock-off lever [2] forwards. To turn off continu-
ous operation, press and release the on-off switch [1] again.
10.3 Power Plug
WARNING!
Risk of injury if the power tool is used with
incorrect mains power supply.
The power tool may only be used with single-phase alternating
current with rated voltage of 220–240 V / 50–60 Hz. The power tool
has double insulation against injury by electric current in line with
