rating label, match with your power supply.
Always install an RCD with a max. trip current
of 30 mA upstream.
Use only extension cables with a min. cross-section
2
of 1.5 mm . Extension cables must correspond to
the power consumption of the machine (cf
Technical Specifications). If a cable roller is used,
always roll up the cable completely.
6.1 Attaching the additional handle
Always work with the additional handle (11)
attached! Manually screw in the additional
handle securely in the left, centre or right threaded
hole (depending on requirements).
6.2 Attach the safety guard
(for working with abrasive discs)
For reasons of safety, the safety guard (12)
should always be attached when roughing
work is performed.

guard should always be attached before
parting work is performed (see chapter 11.
Accessories).
