After charging, the battery may be reinstalled and
the terminal on the battery connected to the termi-
nal on the motor (fig. 18).
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). 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 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
(with the engine off):
1. When the clutch loop is released, it should be
possible to push the mower backwards without
any resistance. If this is not the case, screw in
the nipple T until the mower can be pushed (fig.
19).
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. 10).
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
nipple Y completely screwed in.
SHOCK-ABSORBER
Fig. 20. Check the shock-absorber and the insulat-
ing sleeves twice per season. Replace in the event
of damage or wear.
CHANGING BLADES
To replace the blade, undo the screw (fig. 21, 22).
Fit the new blade so that the stamped logo is
turned up facing the blade holder (not facing the
grass).
Reinstall as illustrated. Tighten the screw properly.
Tightening torque 40 Nm.
When replacing the blade, the blade screw should
also be replaced.
Each intervention on the blade is best if conducted
at a specialised Centre that has the most appropri-
ate tools.
Only blades with the following codes must be used
on this machine:
81004131/0 (for model 454 - fig. 21)
81004132/0 (for model 454 - fig. 22)
81004143/0 (for model 504 - fig. 21)
81004135/0 (for model 504 - fig. 22)
81004144/0 (for model 554 - fig. 21)
81004134/0 (for model 554 - fig. 22)
Blades must always be marked . Given the prod-
uct evolution, the above mentioned blade may be
replaced in time by others, with similar inter-
changeable and operating safety characteristics.
STORAGE
The same petrol must not remain in the tank for
more than one month.
Thoroughly clean the mower and store it indoors in
a dry place.
SERVICING
Genuine spare parts are supplied by service work-
shops and by many dealers.
We recommend that you take the machine to an
