restore.
Manoeuvring the trowel
The trowel is manoeuvred by applying force on the
handle in different directions. The procedure below
describes how to move the trowel in different
directions, but just as important is the balance and
smoothness of the operator to achieve smooth and
easy movements of the machine.

NOTICE Never aim a water jet directly at the fuel
filler cap. This is particularly important when using a
high-pressure cleaner.
The trowel can be leaned forwards and positioned
on the front support frame, when service and
maintenance are carried out. This position is also for
exchange or removal of the blades and the floating
disc.
NOTICE Empty the tank before tilting the machine.
NOTICE It is not permitted to lean the machine in
any other direction. Incorrect leaning direction can
cause problems with engine oil pouring out through
the valve into the carburettor.
