8.6 Belt transmissions
After 5 hours of operation, check that all the belts
are intact and undamaged.
8.7 Steering
The steering must be checked/adjusted after 5
hours of operation and thereafter after 100 hours of
operation.
8.7.1 Checks
Briefly turn the steering wheel back and forth.
There must be no mechanical clearance in the
steering chains.
8.7.2 Adjustment
Adjust the steering chains if required as follows:
1. Put the machine in the straight-ahead position.
2. Adjust the steering chains with the two nuts, lo-
cated under the central point. See fig. 27.
3. Adjust both nuts by the same amount until there
is no clearance.
4. Test drive the machine straight forwards and
check that the steering wheel is not off centre.
5. If the steering wheel is off centre, undo one nut
and tighten the other.
Do not over-tighten the steering chains. This will
cause the steering to become heavy and will in-
crease wear on the steering chains.
8.8 Battery
If acid comes into contact with the eyes
or skin, this can cause serious injuries.
If any part of the body has come into
contact with acid, rinse immediately
with copious amounts of water and seek
medical assistance as soon as possible.
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery fluid does not need to
and cannot be checked or topped up. The only
maintenance that is required is charging, for exam-
ple after extended storage.
The battery must be fully charged be-
fore being used for the first time. The
battery must always be stored fully
charged. If the battery is stored while
discharged, serious damage will occur.
8.8.1 Charging with the engine
The battery can be charged using the engine’s gen-
erator as follows:
1. Install the battery in the machine as shown be-
low.
2. Place the machine outdoors or install an extrac-
tion device for the exhaust fumes.
3. Start the engine according to the instructions in
the user guide.
4. Allow the engine to run continuously for 45
minutes.
5. Stop the engine. The battery will now be fully
charged.
8.8.2 Charging using battery charger
When charging using a battery charger, a battery
charger with constant voltage must be used.
Contact your dealer to purchase a battery charger
with constant voltage.
The battery can be damaged if a standard type
battery charger is used.
8.8.3 Removal/Installation
The battery is placed under the engine casing. Dur-
ing removal/installation, the following applies re-
garding 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.
8.8.4 Cleaning
If the battery terminals are coated with oxide, they
should be cleaned. Clean the battery terminals with
a wire brush and lubricate them with terminal
grease.
8.9 Air filter, engine
The pre-filter (foam filter) must be cleaned/re-
placed after 25 hours of operation.
The air filter (paper filter) must be cleaned/re-
placed after 100 hours of operation.
NOTE! The filters should be cleaned/replaced
more often if the machine operates on dusty
ground.
Remove/install the air filters as follows.
1. Clean carefully around the air filter cover.
2. Dismantle the air filter cover (26:A) by remov-
ing the two clamps.
