Changing Oil; Air Filter - Stiga SILENT 45 COMBI User Manual

CHANGING OIL

Replace the oil when the engine is warm
and the fuel tank is empty. Take care
while draining as the oil is hot, this is to
prevent burns.
Change the oil the first time after 5 hours of oper-
ation, and subsequently after every 50 hours of op-
eration or once a season. Remove the dip stick, tilt
the mower and let the oil run out into a contain-
er.Be careful not to let any oil run on to the grass.
Fill with new oil: use oil of SAE 30 or SAE 10W-
30 quality. The crankcase holds approx. 0.6 litre.
Fill until the oil reaches the "FULL/MAX" mark
on the dip stick.

AIR FILTER

A dirty and blocked air filter reduces the engine
output and increases engine wear.
Clean the filter every three months or after every
25 hours of use, which ever occurs first. More of-
ten if the lawn mower is used on dusty ground.
Briggs & Stratton model. LS45:
Carefully remove the air cleaner so that no dirt falls
down into the carburettor (fig. 19). Take out the
foam plastic filter element and wash it in liquid de-
tergent and water. Dry the filter element. Pour a little
oil on the filter element and squeeze it in. Refit the
air cleaner.
Briggs & Stratton model. ES40:
Loosen the screw and fold down the cover of the
air cleaner. Carefully remove the filter cartridge
(fig. 20). Knock it against a flat surface. Replace
the filter cartridge with a new one if it is still dirty.
SPARKING PLUG
Never remove the spark plug or the igni-
tion lead when checking to see if there is
any spark, always use an approved test
instrument.
Clean the sparking plug regularly (every 100 hours
running). Use a wire brush for cleaning and adjust
the correct spark gap 0,75 mm (fig. 21).
Change the sparking plug if the electrodes are exces-
sively burnt or if the plug is damaged. The recommen-
dations of the engine manufacturers are as follows:
Champion J19LM (RJ19LM) or another equiva-
lent spark plug ought to be used in Briggs & Strat-
ton engines.
ENGLISH
BATTERY (*)
Electrolyte in the battery is toxic and
corrosive. It can cause serious corrosion
damage etc. Avoid all contact with skin,
eyes and clothing.
In normal use during the season, the battery is
charged by the engine. If the engine cannot be
started with the starter key, it may be because the
battery is "dead".
Before starting the mower the first time, you
should charge the battery for 24 hours.
Connect the battery charger to the terminal on the
battery and put on charge for 24 hours (fig. 22). On
completion of charging, connect the battery termi-
nal to the terminal on the motor (fig. 23).
Note! The battery charger must not be connected to
the engine terminal. The engine cannot be started by
using the charger as a source of power supply, and
the charger will be damaged.
WINTER STORAGE
Store the lawn mower for the winter with the bat-
tery well-charged in a dry and cool place (between
0° C and +15° C). At least once during the winter
storage period the battery should be maintenance-
charged. Before the start of the season the battery
should be charged once again for 24 hours.
ADJUSTING THE CLUTCH CABLE (*)
Engage the drive by pressing coupling clamp I
against the steering handle. Should the machine
not start mowing after having operated the clutch
bracket, the cable needs adjusting. For cable ad-
justment, see fig. 24.
CHANGING BLADES
Use protective gloves to prevent cuts
when changing blades/knifeblades.
Check the blade system regularly. Pay
special attention to the curved area be-
hind the blade edge for signs of wear
and tear (fig. 25). If the blade shows
signs of damage, it should be replaced. A
worn down blade creates imbalance and
can damage the mower.
Always check the blade(s) after an impact. First
disconnect the ignition cable. If the blade system
has been damaged the defective parts must be
changed. Always use genuine spare parts.
