A slope inclination of 15° corresponds to a
vertical height increase of 26.8 cm for a
100 cm horizontal distance.
In order to ensure an adequate oil supply
for the engine, the information in the
accompanying engine instruction manual
must be additionally observed when using
the machine on slopes.
Working:
For safety reasons, the machine must
always be operated using both hands,
which must be kept on the handles of the
handlebar at all times during operation.
Never work using only one hand.
Only control the working depth by applying
pressure to the brake spur.
Use the machine with particular care when
operating on difficult (e.g. stony and hard)
ground. Reduce the rotational speed of the
work tools (fuel control).
Only operate the machine at walking
speed – never run when working with the
machine. Working quickly with the
machine increases the risk of injury due to
stumbling, slipping, etc.
Caution – risk of injury!
Exercise particular caution and ensure that
there is sufficient distance between the
work tools (hoes) and your feet when
turning the machine around, pulling it
towards you, or using reverse gear.
Caution – Risk of stumbling!
Watch out for obstacles behind the
operator when moving the machine
backwards.
If the machine becomes stuck, stop the
engine and detach the spark plug socket.
Lift the machine with the help of a second
person and free it.
Stop the engine
– when the machine has to be tilted for
transportation
– when pushing or pulling the machine to
and from the area to be worked
– when leaving the machine unattended
– before re-filling the tank. Allow the
engine to cool down before re-filling the
tank.
Fire hazard!
– when pushing or pulling the machine on
an area that is not to be worked.
Stop the engine and detach the spark plug
socket:
– before remedying blockages
– before lifting or carrying the machine
– before transporting the machine
– before checking or cleaning the
machine or before carrying out any
other work (e.g. adjusting the
handlebar, folding out the transport
chassis) on it
– after hitting a foreign object or if the
machine vibrates excessively. In these
cases, check the machine, in particular
the work tools (hoes, hoe retainers,
drive shaft), for damage and carry out
the necessary repairs before restarting
and working with the machine.
4.7 Maintenance and repairs
Before beginning cleaning, adjustment,
repair and maintenance operations:
● Park the machine on firm and level
ground
● Stop the engine and allow it to cool
down
● Detach the spark plug
socket.
Caution – risk of injury!
Keep the spark plug socket
away from the spark plug; an inadvertent
ignition spark can result in fires or electric
shocks.
Inadvertent contact between the spark
plug and the spark plug socket can result
in unwanted starting of the engine.
Set the machine down on its back only for
cleaning and maintenance work. If
machine is set onto its side or front, this
may cause damage to the engine and
other machine parts, resulting in
expensive repairs.
Allow the machine to cool down before
performing maintenance operations on the
gearbox, engine, exhaust manifold or
Risk of injury!
Never place your hands or feet
above, underneath or on rotating
parts.
Risk of injury!
Strong vibration is normally an
indication of a fault.
In particular, the tiller must not be
operated with a damaged or bent
drive shaft or with damaged work
tools.
If you do not have the appropriate
expertise, have the necessary
repairs carried out by a specialist
dealer (VIKING recommends
VIKING specialist dealers).
