6. Commissioning
Before plugging in, check to see that the
rated mains voltage and mains frequency,
as stated on the rating label, match with your
power supply.
Always install an RCD with a maximum trip
current of 30 mA upstream.
Always use an extension cable with a minimum
diameter of 1.5 mm
suitable for the machine power rating (see
Technical Specifications). If using a roll of cable,
always roll up the cable completely.
6.1 Assembly / setting of additional handle

additional handle (1)supplied.
Option 1
Unscrew the star knob (3). Move the additional

properly.
The additional handle (1) must be reliably
secured against turning. Check that the
knob is tight before using the machine. If
required, tighten the star knob (3) again to
increase the clamping power.
Option 2
Upright working position for reduced stress on the
back when working on floors:
The additional handle (1) can also be attached to
the gear housing. Unscrew the additional handle from the handle holder (2), insert in one of the
threads (6) (on the left and right of the gear housing)
