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. 27) and clean around the transmis-
sion (*) and drive belts (*) with a brush or com-
pressed air once or twice a year.
Once every season, the drive wheels (*) should be
cleaned internally. Remove both wheels. Clean the
gear wheel and the wheel gear rim of grass and dirt
using a brush or compressed air (fig. 18). Replace
the wheel.
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.
LUBRICATING DRIVE SHAFT (*)
Once per season, the wedge on the drive shaft
should be greased. Remove the wheel (wheel cap,
screw and washer). Then remove the circlip and
washer so that the gear wheel can be removed from
the shaft. Lubricate the wedge with universal
grease.
Reinstall the wedge (the wedge is installed differ-
ently on the right and left side, fig. 19-20). Install
the gear wheel so that the L faces out on the left
side and the R faces out on the right side (machine
viewed from the rear).
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.
Briggs & Stratton LS 45 (fig. 21): Carefully re-
move the air cleaner so that no dirt falls down into
the carburettor. Remove the expanded plastic filter
and wash it in liquid detergent 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.
Briggs & Stratton XTE (fig. 22):
Loosen the screw and close 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 fre-
quently if the engine is working on dusty ground.
Honda GCV (fig. 23): Remove the cover and take
out the filter. Carefully check the filter for holes or
other damage. A broken or damaged filter must be re-
placed.
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 use 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. Always use an approved test
instrument.
Clean the spark plug regularly (every 100 hours of
run time). Use a wire brush for cleaning.
Change the spark plug if the electrodes are exces-
sively burnt or if the plug is damaged. The engine
manufacturers recommendations are as follows:
Briggs & Stratton: Champion J19LM (RJ19LM),
spark gap 0.76 mm.
Honda GCV: NGK BPR6ES,
Spark gap 0.7-0.8 mm.
