tended period (more than 1 month), the battery
should be charged, disconnected and then stored in
a cool, safe place. Charge the battery completely
before reinstalling.
The battery can be charged in two ways:
1. You can allow the engine to charge the battery.
In this case it is very important, above all when
starting the machine for the first time and when
it has not been used for a long time, to allow the
engine to run continuously for at least 45 min-
utes.
2. Via a battery charger. This must be a charger
with constant voltage. The battery can be dam-
aged if a standard type battery charger (for acid
batteries) is used.
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 interference
to the strip covering the valves, the bat-
tery should be replaced.
If the battery terminals are coated with oxide, they
should be cleaned. Clean the battery terminals with
a wire brush and grease them.
LUBRICATION
The machine's articulated steering joint has four
grease nipples that should be lubricated with uni-
versal grease after every 25 hours of operation (fig.
14).
Note: The fourth grease nipple is not shown on the
picture. It is located on the underside, on the flexi-
ble axle's front bearing.
Lubricate the steering chain with chain spray a
couple of times per season.
The front wheel hub has grease nipples that should
be lubricated after every 50 hours of operation (fig.
18).
Apply universal grease to all the plastic bearings a
couple of times per season.
Apply a coating of engine oil to the tension arm
joints a couple of times each season.
Apply a few drops of engine oil to both ends of the
throttle control cables a couple of times a season.
ENGLISH
The hydrostatic transmission is filled with oil
(10W-40) on delivery from the factory. Unless it is
opened (only to be performed by a specialist), and
provided no leakage occurs, no topping up with oil
should normally be carried out. Transmission oil
does not normally need to be changed.
STEERING CABLES
The steering cables should be adjusted for the first
time after the machine has been in operation for 2
- 3 hours, and then after every 25 hours of opera-
tion.
Put the machine in the straight-ahead position.
Tension the steering cables by tightening the nuts
that are located on the underside of the articulated
steering joint (fig. 15). The screws in the ends of
the cables should be held firmly during adjustment
so that the cables are not twisted. Use an adjustable
wrench or similar for this purpose, inserting it in
the key handles in the ends of the screws. Tension
until all play is removed.
Adjust both the nuts the same amount to ensure
that the alignment of the steering wheel is not
changed.
Once the adjustment is complete, turn the steering
wheel as far as it will go in either direction. Check
that the chain does not come into contact with the
pulley, and that the cables do not become entan-
gled with the steering pinions.
Do not tension the steering cables too hard. Other-
wise the steering will be heavy and wear and tear
on the cables will increase.
