Level 6 = 75 mm
Setting the cutting height:
● Hold the handle (1), pull the lever (2)
upwards and hold.
● Set the required cutting height by
moving the machine upwards and
downwards. The current cutting height
can be read off at the cutting height
indicator (3) by means of the
marking (4).
● Release the detent lever (2) and allow it
to engage.

8.5 Level indicator

The upper part of the grass catcher
box features a level indicator (1).
The flow of air that is created by the rotary
movement of the mowing blade and is
responsible for filling the grass catcher box
raises the level indicator (2):
The grass catcher box is filled with

9. Notes on working with the

machine
9.1 General
Risk of injury!
Untangle any knots in the cable
immediately.
Guide the electric cable behind you
when mowing. Electric cables can
be inadvertently cut when mowing
and present a tripping hazard. They
therefore involve a high accident
risk. For this reason, mow so that
the electric cable is always visible
in the area of grass that has already
10
been cut.
To ensure a perfect, thick lawn, mow
regularly and keep the grass short.
Do not cut the lawn too short in hot, dry
conditions as it will dry out or burn in the
sun and become unsightly.
The cutting pattern will be better with a
sharp blade than with a blunt one; the
blade should therefore be sharpened
regularly (VIKING specialist dealer).
11.5).

9.2 Correct motor load

Do not switch on the lawn mower in tall
grass or at the lowest cutting height.
The lawn mower load must never cause
the motor speed to drop significantly.
If the speed drops, select a higher cutting
height setting and/or reduce the rate of
feed.

9.3 If the mowing blade blocks

Switch off the motor immediately and
disconnect the mains plug. Then eliminate
the cause of the fault.

9.4 Thermal motor overload protection

If an overload of the motor occurs during
operation, the built-in thermal overload
protection device automatically switches
off the motor.
Causes for an overload:
– mowing excessively high grass or
cutting height adjusted too low,
– excessive rate of feed,
– inadequate cleaning of the cooling air
guide (inlet slots),
– mowing blade is blunt or worn,
– unsuitable or excessively long electric
cable – voltage loss ( 11.1).
Recommencing operation
Resume normal operation of the machine
following a cooling period of up to 10 min
(depending on the ambient temperature)
( 11.).

10. Safety devices

The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
Risk of injury!
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; VIKING recommends
