ENGLISH GB
Do not set the cutting height so low that the
blade comes 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. 19).
MAINTENANCE
No servicing may be carried out on the
engine or lawnmower without first
removing 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 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 casing by removing the
screws S (fig. 20) and clean around the
transmission and drive belts with a brush or
compressed air once or twice a year.
The drive chain should be lubricated once per
season. Remove the right-hand cover from the
roller and apply a little chain spray onto 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
Change 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
operation, and subsequently every 50 hours of
operation 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 litres. Fill until
the oil reaches the “FULL/MAX” mark on the
dipstick.
AIR FILTER
A dirty and blocked air filter reduces the engine
output and increases engine wear.
Briggs & Stratton (fig. 21):
Undo the screw and fold down the cover of the air
cleaner. Carefully remove the filter cartridge.
Knock it against a flat surface. Replace the filter
cartridge with a new one if it is still dirty.
Clean the filter every three months or after every
25 hours of use, whichever occurs first. More
frequently if the engine is working on dusty
ground.
Honda (fig. 22): Remove the cover and take out the
filter. Carefully check the filter for holes or other
damage. A broken or damaged filter must be
replaced.
To remove dirt, carefully knock the filter several
times against a hard surface or use compressed air
from the back of the filter to blow-clean. Do not try
to brush the filter clean as this forces dirt down into
the fibres. A very dirty filter should be replaced.
Clean the air filter after every 25 hours of
operation or once a season. More frequently 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. Use an approved test
instrument.
Clean the spark plug regularly (every 100 hours of
run time). Use a wire brush for cleaning.
