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. 15-16). 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 (fig. 17):
Carefully remove the
air cleaner so that no dirt falls down into the carbu-
rettor. 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. Re-
install 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.
Honda (fig. 18):
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:
(fig. 19):
Briggs & Stratton:
Champion J19LM (RJ19LM),
spark gap 0.76 mm.
Honda:
NGK
BPR6ES,
Spark gap 0.7-0.8 mm.
ADJUSTING CLUTCH CABLE (*)
If the drive does not engage when the clutch loop
is pressed against the handle, or if the lawnmower
feels cumbersome or slow, this may be because the
clutch in the transmission is slipping. To rectify
this situation, adjust the clutch cable as follows:
1. When the clutch loop is released, it should be
possible to push the mower without any resist-
ance. If this is not the case, screw in the nipple
T
until the mower can be pushed (fig. 21).
2. When the clutch loop is
pressed in approx. 2 cm (posi-
tion 1), there should be some
resistance when pushing the
lawnmower. With the clutch
loop fully pressed in (position
2) it should not be possible to
push the mower. Unscrew the
nipple
T
until this position is
achieved.
