Assembly
Mounting the Protective Devices
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 5.
Screw the auxiliary handle 5 on the right or left
of the machine head depending on the working
method.
With the handle extension 4, the auxiliary han-
dle 5 can be mounted above the gear head, pro-
viding a favourable centre of gravity. Depending
on the working manner, screw the handle exten-
sion 4 to the right or left on the gear head.
Hand Guard
When working without the handle extension 4,
the hand guard 9 should be mounted.
The hand guard 9 is fastened with the auxiliary
handle 5.
Protective Cap for Gear Head
The gear head warms up when working with the
machine. The protective cap 1 can be used as a
contact protector.
Mount the protective cap 1 onto the gear head
and fasten it with fastening screw 2 and the aux-
iliary handle 5.
