6. Commissioning
If delivered without a mains plug, arrange for a
suitable mains plug to be connected by a
qualified electrician ONLY.
Before plugging in, check to see that the rated
mains voltage and mains frequency, as
specified on the rating label, match your power
supply.
Always use an extension cable with a minimum
2
diameter of 1.5 mm . The extension cable must be
suitable for the machine power rating (see
Technical Specifications). If using a roll of cable,
always roll up the cable completely.
6.1 Attaching the additional handle
Always work with the additional handle
attached (10)! Manually screw in the
additional handle securely in the left, centre or right
threaded hole (depending on requirements).
6.2 Attaching the safety guard
(for work involving grinding wheels)
Prior to commissioning: Fit the
protective cover.
For reasons of safety, the safety guard (11)
should always be attached when roughing
work is performed.
For reasons of safety, the special parting
guard should always be attached before
parting work is performed (see chapter 11.
Accessories).
See illustration E on page 2.

6.4 Power supply
The mains sockets must be protected using time-
delay fuses or circuit breakers.
Machines with "X" in the model designation:
(with integrated, automatic restriction of the starting
current (soft start)). The mains sockets can also be
protected using fast-acting fuses or circuit breakers.

7. Attaching the grinding wheel
