SPEED
Do not touch the variator control when
the engine is not running. This can dam-
age the operation of the variator.
Set to a suitable speed by moving the variator con-
trol to one of the 4 positions (fig. 13).
The various positions have the following speeds:
Position :approx. 2.8 km/h
Position 2: approx. 3.1 km/h
Position 3: approx. 3.6 km/h
Position :approx. 4.5 km/h
CUTTING HEIGHT
Shut off the engine before adjusting the
cutting height.
Do not set the cutting height so low that
the blade come into contact with uneven
ground.
The mower has single-lever control for adjusting
the cutting height. Pull the lever out, and set the
cutting height to one of the positions best suited to
your lawn (fig. 14).
MAINTENANCE
No servicing may be carried out on the
engine or lawnmower without first re-
moving the spark plug cable from the
spark plug.
Stop the engine and remove the spark
plug cable if the mower is to be lifted,
e.g. during transportation.
If the lawnmower needs to be tilted, it
must be tilted so that the engine’s spark
plug faces upwards. Tilt the lawnmower
when the fuel tank is empty.
CLEANING
After each use the mower should be cleaned. This
is particularly important on the underside of the
mower casing. Rinse clean with the garden hose.
The mower will then last longer and work better.
High-pressure washers should not be used.
If grass has dried on to the mower casing, it can be
scraped clean. If necessary, touch up the underside
with paint to prevent rust damage.
Clean the silencer and the surrounding
area regularly to remove grass, dirt and
flammable waste products.
Remove the transmission cover by removing the
screws
S (fig. 20) and clean around the transmis-
sion and drive belts with a brush or compressed air
once or twice a year.
Once every season, the drive chain should be lubri-
cated. Remove the right hand roller cover and add
a small amount of chain oil to the chain.
COOLING SYSTEM
Before each use, the engine’s cooling system must
be cleaned. Clean the cylinder’s cooling flanges
and air intake of grass remains, dirt, etc.
OIL CHANGE
Replace the oil when the engine is warm
and the fuel tank is empty. In order to
prevent burns, take care while draining
as the oil is hot.
Change the oil the first time after 5 hours of oper-
ation, and subsequently every 50 hours of opera-
tion or once a season. Remove the dipstick, tilt the
mower and let the oil run out into a container. Be
careful not to let any oil run on to the grass.
Fill with new oil: Use SAE 30 or SAE 10W-30 oil.
The crankcase holds approx. 0.55 litre. Fill until
the oil reaches the “FULL/MAX“ mark on the dip-
stick.
AIR FILTER
A dirty and blocked air filter reduces the engine
output and increases engine wear.
Carefully remove the air cleaner so that no dirt
falls down into the carburettor (fig. 15). Remove
the expanded plastic filter and wash it in liquid de-
tergent and water. Dry the filter. Pour a little oil on
the filter and squeeze it in. Reinstall the air cleaner.
Clean the filter every three months or after every
25 hours of use, whichever occurs first. More fre-
quently if the engine is working on dusty ground.
SPARK PLUG
Never remove the spark plug or spark
plug cable when checking to see if there
is a spark. Always use an approved test
instrument.
