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 850-125, 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.
11. Accessories
Use only genuine Metabo accessories.
See page 4.
Only use accessories which fulfil the requirements
and specifications listed in these operating
instructions.
A Cutting guard clip / guard for cut-off
grinding
Designed for work with cutting disc and diamond
cutting discs. Once the cutting guard clip is fitted,
the safety guard becomes a cutting guard.
B Extraction guard for cut-off grinding
18
Designed for cutting through stone slabs with
diamond cutting discs. With nozzle for extracting
stone dust using a suitable extraction unit.
C Hand protection
Intended for work with backing pads, sanding
plates, wire brushes and support plates, sanding
pads, wire brushes and diamond drill bits for tiles.
Install the hand guard under the additional side-
mounted handle.
D Two hole nut (12)
E M-Quick clamping nut (1)
F Clamping nut (tool-free) (14)
For a complete range of accessories, see
www.metabo.com or the accessories catalogue.
12. Repairs
Repairs to electrical tools must ONLY be
carried out by qualified electricians!
Contact your local Metabo representative if you
have Metabo power tools requiring repairs. See
www.metabo.com for addresses.
You can download a list of spare parts from
www.metabo.com.
13. Environmental Protection
The sanding dust generated may contain
hazardous materials: do not dispose of dust with
household waste, but at a special collection point
for hazardous waste.
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
on Waste from Electric and Electronic Equipment
and implementation in national law, used power
tools must be collected separately and recycled in
an environmentally-friendly manner.
