5.9.3 Removal/Installation
The battery is placed under the tank. To access the
battery, first dismantle the fuel tank as follows:
1. Open the engine casing.
2. Close the fuel cock, see 14.
3. Unscrew the two wing nuts (16:B) and remove
the clamps.
4. Carefully lift up the petrol tank.
During removal/installation of the battery, the fol-
lowing applies regarding connection of the cables:
During removal. First disconnect the black ca-
ble from the battery’s negative terminal (-).
Then disconnect the red cable from the battery’s
positive terminal (-).
During installation. First connect the red cable
to the battery’s positive terminal (+). Then con-
nect the black cable to the battery’s negative ter-
minal (-).
If the cables are disconnected/connect-
ed in the wrong order, there is a risk of
a short-circuit and damage to the bat-
tery.
If the cables are interchanged, the gen-
erator and the battery will be damaged.
Tighten the cables securely. Loose ca-
bles can cause a fire.
The engine must never be driven with
the battery disconnected. There is a risk
of serious damage to the generator and
the electrical system.
When the battery has been rectified, install the fuel
tank as follows:
Check that the petrol hose is not
clamped against the hydraulic pump
and does not come into contact with
this. The hydraulic pump becomes very
hot during operation. Risk of fire.
1. Place the petrol tank on the brackets. Check that
the petrol hose is not touching the hydraulic
pump.
2. Install the clamps and tighten the wing nuts
(16:B).
