Assembly
Remove the power tool from the packaging. Do not plug it into the electrical grid before
assembly.
Mounting of Accessories
The grinding disc or cut-off wheel may never be larger than the prescribed diameter.
Before using the grinding disc or cut-off wheel, check its specified rotational speed. The
rotational speed of the grinding disc or cut-off wheel must be equal to or greater than
the idle rotational speed of the angle grinder.
Use only grinding discs or cut-off wheels that are approved for a rotational speed of at
least 12,500 U/min and a peripheral velocity of at least 80 m/sec.
• Easy disc replacement through the use of the spindle lock. Press down on the spindle
lock (1) and let the grinding disc or cut-off wheel lock into place. Loosen the flange
nut with the open-ended spanner (7). Replace the grinding disc or cut-off wheel and
tighten the flange nut with the open-ended spanner (7).
Please note:
Only press down on the spindle lock (1) when the power plug is pulled out of the
electrical socket and the grinding spindle is at a standstill! The spindle lock must
remain pressed down during the disc or wheel replacement.
For grinding discs or cut-off wheels up to a thickness (strength) of approx. 3 mm,
unscrew the flange nut with the planar side to the grinding disc or cut-off wheel (Fig. 2
and 3). For discs or wheels greater than 3 mm in thickness (strength), mount the flange
nut according to (Fig. 1).
