Switching on and off

Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
The machine must not be allowed to draw in
additional dust and shavings. When switching
the machine on and off and keep it away from dust
deposits. After switching off the machine, only set it
down when the motor has come to a standstill.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand
securely and concentrate.

Switching on: push the slide switch (5) forwards.
For continuous operation, tilt it downwards until it
engages.

8.3 Working Directions
Grinding and sanding operations:
Press down the machine evenly on the surface and
move it back and forth so that the surface of the
workpiece does not become too hot.
Rough grinding: position the machine at an angle of
30° - 40° for the best working results.
Cut-off grinding:
Always work against the run of the disc
(see illustration). Otherwise the
machine may kick back from the cut in
an out of control manner. Guide the
machine evenly at a speed suitable for
the material being processed. Do not tilt, apply
excessive force or sway from side to side.
Wire brushing:
Press down the machine evenly.
9. Cleaning
Particles may become deposited inside the power
tool during operation. This impairs the cooling of the
power tool. Conductive build-up can impair the
protective insulation of the power tool and create an
electrical hazard.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner or by blowing in dry air.
Prior to this operation, separate the power tool from
the power source and wear protective glasses and
suitable dust mask. Ensure appropriate suction is
available when blowing out vents.
10. Troubleshooting
(equipment-specific)
The machine does not start. Restart
protection is active. If the mains plug is
inserted with the machine switched on or if the
power supply is restored following an interruption,
the machine does not start up. Switch the machine
off and back on again.
WEV 850-115, WEV 850-125, WEQ 1400-125 only:
The speed drops while the machine is
under load. There is too much load on the
machine! Allow the machine to run at idle
speed until it has cooled down.

See page 4.
Only use accessories which fulfil the requirements
and specifications listed in these operating
instructions.
Always use the suitable accessory and the
prescribed guard for the matching guard for
the application. See page 4. (Illustrations are
examples).
