Oil type winter: SAE 5W-30
(SAE 10W-30 can also be used).
Use oil without any additives.
Do not fill too much oil as this can result in over-
heating of the engine.
Check the oil every time when topping up. The
level should come up to the "FULL" mark.
LUBRICATION
The machine has three grease nipples G on the rear
axle which are lubricated with universal grease
every 25 hours running (fig 12 - 13).
All plastic bearings (rear wheel, steering turntable,
pedal and steering column bearings, as well as ca-
ble rollers) are lubricated with universal grease
twice per season.
The power take-off and clutch tensioning arm
joints are lubricated with universal grease twice
per season.
Grease the steering cable regularly. This is essen-
tial to the service life of the cable.
The drive chain H and other mechanically actuated
joints are lubricated with oil twice per season (fig
18).
The gearbox and differential are filled with grease
at the factory. If they are not opened (which must
only be done by a specialist), no filling with grease
should normally be done.
AIR FILTER
Important! Never operate the engine without the
air cleaner being fitted.
Clean the foam pre-filter I every 3 months or after
every 25 hours of operation, whichever comes first
(fig 14).
Clean the paper filter insert J once a year or after
every 100 hours of operation, whichever comes
first (fig 14).
NOTE! The filter should be cleaned more often if
the machine operates on dusty ground.
1. Remove the protective cover of the air filter and
the foam plastic filter.
2. Wash the pre-cleaner in liquid detergent and wa-
ter. Squeeze dry. Pour a little oil on the filter and
squeeze in the oil.
3. Loosen and remove the nut which hold the paper
ENGLISH
filter. Lift our the paper filter and thoroughly clean
the air filter housing to prevent dirt from entering
the carburettor.
4. Clean the paper filter as follows: Knock it light-
ly against a flat surface. If the filter is very dirty,
change it.
5. Assemble in the reverse order.
Petroleum-based solvents such as kerosene must
not be used for cleaning the paper filter as these
can destroy the filter.
Do not use compressed air for cleaning the paper
filter. The paper filter must not be oiled.
COOLING AIR INTAKE
The engine is air-cooled. A blocked cooling sys-
tem can damage the engine. The engine should be
cleaned at least once a year or every 100 hours run-
ning.
Remove the fan casing. Clean the cooling fins on
the cylinder, the fan and the rotating protective
grille (fig 15). Glean more frequently if mowing
dry grass.
SPARKING PLUG
An oily and sooty sparking plug with burnt elec-
trodes makes the engine difficult to start.
Clean the plug with a wire brush (do not sand-
blast) and reset the spark gap to 0.75 mm.
Replace the sparking plug if the electrodes are bad-
ly burnt. For replacing a sparking plug, a sparking
plug sleeve AC and torsion pin AD are provided in
the plastic bag containing accessories.
The engine manufacturer recommends: Champion
J19LM.
CARBURETTOR
The carburettor is positioned at the factory and ad-
justment should not be necessary.
If the carburettor after all has to be adjusted, con-
tact a service station.
ADJUSTING POWER TAKE - OFF
If the v-belt on the double belt pulley slips when
the power take-off is engaged it can be tensioned
by screwing in the nut K on the power take-off rod
(fig 16).
