get on the V-belts.
2. Screw in the oil drain plug. Make sure that the
fibre gasket and the O-ring inside the plug are not
damaged and that they are in the correct place.
3. Remove the dipstick and fill up with new oil.
Oil capacity: 1.4 litres
Oil type, summer (> 4ºC): SAE-30
(SAE 10W-30 can also be used. However, oil con-
sumption may increase somewhat if 10W-30 is
used. Therefore, check the oil level more regularly
if you use this type of oil).
Oil type, winter (< 4ºC): SAE 5W-30
(if this oil is not available, use SAE 10W-30).
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
After filling up the oil, start the engine and idle for
30 seconds. Stop the engine. Wait for 30 seconds
and then check the oil level.
Check to see if there is any oil leakage. If neces-
sary, fill up the oil up to the “FULL” mark.
AIR FILTER - ENGINE
Change the pre-filter once a year or every 25 hours
of operation.
Clean the paper filter insert once a year or after
every 100 hours of operation, whichever comes
first.
NOTE! Both filters should be replaced/cleaned
more often if the machine operates on dusty
ground.
1. Remove the protective cover on the air filter
(fig. 10).
2. Dismantle the paper filter insert and the foam
pre-filter. Make sure that no dirt gets into the car-
burettor. Clean the air filter housing.
3. Replace the pre-filter.
4. Clean the paper filter insert as follows: Knock it
lightly against a flat surface. If the filter is very
dirty, change it.
5. Assemble in the reverse order.
Petroleum-based solvents such as kerosene may
not be used for cleaning the paper filter insert.
These solvents can destroy the filter.
Do not use compressed air for cleaning the paper
filter insert. The paper filter insert must not be
oiled.
SPARK PLUG
Clean the spark plug after every 100 hours of oper-
ation or once a season. For replacing a spark plug,
a spark plug sleeve A and a torsion pin B are pro-
vided in the accessories bag.
The engine manufacturer recommends:
Champion RC12YC .
Correct spark gap: 0.7 - 0.8 mm (fig. 11).
COOLING AIR INTAKE - ENGINE
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 of
operation.
Remove the fan casing. Clean the cooling fins on
the cylinder, the fan and the rotating protective
grille. Clean more frequently if mowing dry grass.
LUBRICATION
The machine’s articulated steering joint has four
grease nipples that should be lubricated with uni-
versal grease after every 25 hours of operation (fig.
13).
Note: The fourth grease nipple is not shown on the
picture. It is located on the underside, on the flexi-
ble axle’s front bearing.
Lubricate the steering chain with chain spray a
couple of times each season.
The front wheel hub has grease nipples that should
be lubricated after every 50 hours of operation.
Apply universal grease to all the plastic bearings a
couple of times per season.
Apply a coating of engine oil to the tension arm
joints a couple of times each season.
Apply a few drops of engine oil to both ends of the
throttle control cables a couple of times a season.
4155H:
The hydrostatic transmission is filled with oil
(10W-40) on delivery from the factory. Unless it is
opened (only to be performed by a specialist), and
provided no leakage occurs, no topping up with oil
should normally be carried out. Transmission oil
does not normally need to be changed.
