All manuals and user guides at all-guides.com
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
Unscrew the oil drain plug at the end of the pipe
(fig. 10).
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
Screw in the oil drain plug. Make sure that the fibre
gasket and the O-ring inside the plug are not dam-
aged and that they are in the correct place.
Remove the dipstick and fill up with new oil up to
the "UPPER" mark.
Oil quantity: 0.9 l (= oil quantity at change. In to-
tal the engine holds 1.15 l).
Oil type for all seasons: SAE 10W-40.
For extremely low temperatures (< -20° C), use
SAE 5W-30.
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.

lightly against a flat surface. If the filter is very
dirty, change it.

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:
Master - Senator - President: Champion J19LM.

Correct spark gap: 0.75 mm (fig. 13).
COOLING AIR INTAKE - ENGINE
(Master - Senator - President)
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 (fig. 14). Clean more frequently if mowing
dry grass.
BATTERY
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery is completely main-
tenance free. You don't have to check or top up the
electrolyte level (fig. 15).
On delivery, the battery is in the accessories box.
The battery must be fully charged be-
fore being used for the first time. The
battery should always be stored fully
charged. If the battery is stored while
totally flat it could sustain permanent
damage.
If the machine is not going to be used for an ex-
tended period (more than 1 month), the battery
should be charged, disconnected and then stored in
