drained off directly after switching off
the engine. For this reason allow the en-
gine to cool for a few minutes before
draining the oil.
Unscrew the oil drain plug in the end of the tube
(fig. 11).
Let the oil run out into a collection vessel. Then
take the oil to a recycling station. Avoid spilling
oil on the V-belts.
Screw tight the oil drain plug. Make sure that the
fibre gasket and O-ring inside the plug are undam-
aged and in the correct position.
Take out the oil dipstick and fill up with new oil to
the “FULL” mark.
Oil capacity:
Royal – 0.9 litre (= when changing; total engine
capacity is 1.15 litre).
Oil type for all seasons: SAE 10W-40.
Fir very low temperatures (< -20° C), use SAE
5W-30.
Do not use any additives with the oil.
Do not overfill. This can result in the engine over-
heating.
AIR FILTER - ENGINE
Master-Senator-Comfort-President:
Clean the pre-filter every year or after every 25 op-
erating hours, whichever comes first.
Clean the paper filter every year or every 100 op-
erating hours, whichever comes first.
Royal:
Clean the air filter (per-filter and paper filter) every
3 months or after every 50 operating hours, which-
ever comes first. Change the paper filter every year
or every 200 operating hours.
All models:
NOTE! Clean both filters more often if the ma-
chine is used in dusty conditions.
1. Remove the air filter cover (fig. 12 - 13).
2. Dismantle the paper filter and pre-filter (= foam
plastic filter). Make sure that no dirt gets into the
carburettor. Clean the air filter housing.
3. Wash the pre-filter in liquid detergent and water.
Squeeze dry. Pour a little on the filter and squeeze
in the oil.
4. Clean the paper filter as follows: Tap it lightly
against a flat surface. If the filter is very dirty, re-
place it.
5. Assemble in the reverse order.
Petroleum-based solvents such as kerosene must
not be used to clean the paper filter. These solvents
will damage the filter.
Do not use compressed air to clean the paper filter.
The paper filter must not be oiled.
SPARK PLUG
Change the spark plug after every 100 hours of op-
eration or every season. In the accessory bag there
is a spark plug sleeve A and torsion pin B to
change the spark plug.
The engine manufacturer recommends:
Master - Senator - Comfort - President: Champion
J19LM.
Royal: NGK BPR5ES or DENSO W16EPR-U.
Correct electrode gap: 0.75 mm (fig. 14).
COOLING AIR INTAKE - ENGINE
(Master - Senator - Comfort - Presi-
dent)
The engine is air-cooled. A blocked cooling sys-
tem can damage the engine. The engine should be
cleaned every 100 hours of operation or at least
once a year.
Remove the fan casing. Clean the cooling fins on
the cylinder, the fan and the rotating protective
grille (fig. 15). Clean more frequently if moving
dry grass.
BATTERY
Check the acid level regularly.
The acid level should lie between the “UPPER”
and “LOWER” markings on the battery (fig. 16).
When adjusting the acid level, only use distilled
water.
The battery acid is extremely corrosive
and can cause burns on the skin and
clothing. Use rubber gloves and protect
your eyes with protective glasses. Avoid
inhaling the acid fumes.
