ENGLISH GB
Change the spark plug if the electrodes are
excessively burnt or if the plug is damaged. The
engine manufacturers’ recommendations are as
follows:
Briggs & Stratton: Champion J19LM (RJ19LM),
Spark gap 0.76 mm.
Honda: NGK BPR6ES,
Spark gap 0.7-0.8 mm.
BATTERY (*)
The 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 ignition key, it may be because the
battery is ‘dead’.
Dismantle the battery by opening the battery
cover, disconnecting the terminal on the engine
and removing the battery (fig. 23). Connect the
battery charger (provided) to the battery, then
connect the charger to a wall socket and charge for
24 hours (fig. 24).
After charging, the battery may be reinstalled and
the terminal on the battery connected to the
terminal on the engine (fig. 25).
The battery charger may not be connected directly
to the engine terminal. It is not possible to start the
engine with the charger as the power source and
the charger could be damaged.
WINTER STORAGE
Remove the battery and store it fully charged (see
above) in a dry, cool place (between 0°C and
+15°C). The battery should be maintenance-
charged at least once during the winter storage
period.
Before the start of the season, the battery should be
charged once again for 24 hours.
ADJUSTING CLUTCH CABLE
If the drive does not engage when the clutch loop
is pressed against the handle, or if the lawnmower
feels cumbersome or slow, this may be because the
clutch in the transmission is slipping. To rectify
this situation, adjust the clutch cable as follows:
1. When the clutch loop is released, it should be
possible to push the mower without any
resistance. If this is not the case, screw in the
nipple T until the mower can be pushed (fig.
26).
2. When the clutch loop is
pressed in approx. 2 cm
(position 1), there should be
some resistance when
pushing the lawnmower.
With the clutch loop fully
pressed in (position 2) it
should not be possible to push
the mower. Unscrew the
nipple T until this position is
achieved.
ADJUSTING VARIATOR CABLE
If the speed difference between the settings in the
variator control giving the fastest speed (position 3
and
) appears insignificant or nothing at all, the
variator cable might need tightening (fig. 18).
1. Run the mower for a few minutes in position
.
2. If the variator cable shows some play in nipple
Y it needs tightening. Undo the locking nut X
and tighten the cable by unscrewing the nipple
Y until the cable ceases to show any play.
3. Tighten the locking nut X.
NOTE! Do not stretch the cable beyond the point
where there is no play in the nipple Y. If the cable is
over-tightened, the drive belt could break and/or
other parts of the transmission be damaged. When
setting after e.g. belt change, always start with the
nippleY completely screwed in.
CHANGING BLADES
Use protective gloves when changing
blade to avoid cutting yourself.
Check the blade system regularly. Check
particularly the curved area behind the
blade edge for traces of wear. If the blade
shows traces of damage it should be
replaced. A worn blade creates imbalance
and can damage the mower.
Always check the blade after an impact. First
disconnect the spark plug cable. If the blade
system has been damaged, defective parts should
be replaced. Always use genuine spare parts.
