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.
