Switching off: Release the trigger switch (8).
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.
Before doing so, separate the power tool from the
power source and wear protective goggles and a
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.

Observe national regulations on environmentally
compatible disposal and on the recycling of disused
machines, packaging and accessories.
Only for EU countries: never dispose of
power tools in your household waste!
According to European Directive 2012/19/EU

tools must be collected separately and recycled in
an environmentally-friendly manner.
