1 Setting the rear cutting height
● Set the required cutting height at the
rear axle (1).
For this purpose, support the machine
with one hand and move the rear axle to
the desired level on one side first and
then on the other.
Ensure that the left and right sides are
at the same level (rear axle parallel to
the housing).
2 Setting the front cutting height
● MB 2 RT:
Push the cutting height adjustment
lever (2) outwards, move to the desired
level and allow it to engage.
● MB 2 RC, MB 2 R:
Set the required cutting height at the
front axle (3).
For this purpose, support the machine
with one hand and move the front axle
to the desired level on one side first and
then on the other. Ensure that the left
and right sides are at the same level
(front axle parallel to the housing).

9. 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
VIKING specialist dealers.

9.1 Motorstop lever

The lawn mower is equipped with a
motorstop device.
The engine stops when the motorstop
lever is released during running operation.
The engine and blade come to a standstill
within 3 seconds.
Risk of injury!
If the run-on time of the blade
exceeds this delay, stop using the
machine and take it to your
specialist dealer.
Measuring the run-on time
Following engine start-up, the blade
rotates and a wind noise is audible. The
run-on time corresponds to the duration of
the wind noise after the engine stops. This
can be measured using a stopwatch.
10. Notes on working with
the machine

10.1 General information on mulching

During mulching, the cut grass is chopped
up several times through a special air flow
guidance system in the mower blade area
and then blown back into the turf. The
clippings remain on the lawn.
Benefits
The decomposing clippings return organic
nutrients to the soil, serving as a natural
fertiliser.
Advantages
Emptying the grass catcher box and
disposal of the clippings are dispensed
with. Weed growth is slowed down and
significant amounts of fertilizer are saved.

10.2 When is mulching permissible?

VIKING recommends mulching only when
the lawn is dry and the grass is not too
high.
If the grass is too high, the lawn should be
mowed in two stages. ( 10.3)
Caution
If the cutting height is too low or the
grass is wet, the housing may
become clogged, blocking the
blade!
10.3 How should mulching be
performed?
Requirements for good mulching results:
– Set the optimal cutting height: A third of
the grass height should be cut.
– Use well sharpened blades.
– Vary the mowing direction and ensure
that the mowing strips overlap.
Working method in high grass
In high grass, the lawn should be cut in two
stages.
First stage:
The lawn is mowed at the maximum
cutting height.
Second stage:
12 to 24 hours after the first stage, mulch
the lawn to the desired grass height at right
angles to the first mowing direction.
