Air Filter - Engine; Spark Plug - Stiga READY Instructions For Use Manual

Change oil when the engine is warm. Always use
a good grade of synthetic oil (service grade SF, SG
or SH).
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 (fig. 8). It is situated on
the left of the engine (machine viewed from the
rear).
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.
Remove the dipstick and fill up with new oil to the
"FULL" mark.
Oil capacity: 1.4 litres
Oil type, summer (> 4ºC): SAE-30
(SAE 10W-30 can also be used. However, oil
consumption 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.

5.5 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. 9).
2. Dismantle the paper filter insert and the foam
pre-filter. Make sure that no dirt gets into the
carburettor. 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.

5.6 SPARK PLUG

Clean the spark plug after every 100 hours of
operation or once a season. For replacing a spark
plug, a spark plug sleeve A and a torsion pin B are
provided in the accessories bag.
The engine manufacturer recommends:
Champion RC12YC.
Correct spark gap: 0.7 - 0.8 mm (fig. 10).
5.7 COOLING AIR INTAKE - ENGINE
The engine is air-cooled. A blocked cooling
system 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.
5.8 Battery
Do not short circuit the battery's termi-
nals. Sparks occur which can result in
fire. Do not wear metal jewellery which
can come into contact with the battery
terminals.
In the event of damage to the battery
casing, cover, terminals or damage to
the strip covering the valves, the bat-
tery should be replaced.
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery fluid does not need to
and cannot be checked or topped up. The only
maintenance that is required is charging, for exam-
ple after extended storage.
After charging the battery must be stored in a cool
place.
The battery must be fully charged be-
fore being used for the first time. The
battery must always be stored fully
charged. If the battery is stored while
discharged, serious damage will occur.
5.8.1 Charging using battery charger
The battery should ideally be charged using a bat-
tery charger with constant voltage.
Contact your dealer to purchase a battery charger
with constant voltage.
The battery can be damaged if a standard type
battery charger (for acid batteries) is used.
The battery is fully charged after approximately 5
hours.
5.8.2 Charging with the engine
The battery can also be charged using the engine's
generator as follows:
1. Install the battery in the machine as shown be-
low.
