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.

8.9Air 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.
