original position.
! When the guard opened an eye on particles and dust
coming from the unprotected - the open part of the
shield.
! Overhead of the shield should be a nice fit on the fixed
part.

from the user.
Replacing the brush ring - Figure 5
Guard is equipped with a brush ring that fits onto the
ground to prevent dust emission and holds small pieces.
The brush ring is worn out and needs to be changed
when it wears out.
Place the vacuum cleaner dust
In grinding occurring mineral powder, which is
obligatory vacuming that there is no emission of dust
and overheating of the grinding wheel.
• Insert the suction hose in the intake nozzle that fits
comfortably and with a slight twist to secure the cone.

OPERATION
!
Power supply voltage must correspond to the data
on the tool's nameplate. Power tools marked with
230V can also be connected to 220V mains. Power
tools marked with 120V can also be connected to
110V mains.
Tool start-up
• Switching ON: Push the ON/OFF switch forward,
Figure 6.
Hold the tool firmly when you switch it on.
• Switch lock-off: Push the switch button forward and
press the front part in order to lock it.
• Switching OFF: Press the rear part of the ON/OFF
switch (Figure 6). The button will return to its original
OFF position.
!
Switch off the power tool only when it is no longer
in contact with the workpiece.
Working with the power tool
!
Before using the tool check if the grinding disc is
positioned and fixed correctly to the tool and let it
run unloaded for 60 seconds in a safe position for
the user.
!
If strong vibrations appear or if you notice any
irregularity in its operation, immediately switch off
the tool and mount another grinding / cutting disc.
If the situation is not improved, take the tool to an
authorized service centre.
!
Fix the workpiece.
Start working only when the disc has reached its full
speed.
Excessive pressure on the tool will not improve either the
speed or the quality of the work. It will merely fatigue the
tool and shorten its service life.
!
In case the tool is jammed, immediately switch it
off and unplug it. Continue working only when the
cause of jamming has been removed.
!
Never cover ventilation slots on the motor
housing. Closed ventilation slots will cause motor
overheating and damage to the tool.

source before making any adjustments on
