5.11.2 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.

5.11.3 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.

5.11.4 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.

5.12 Air filter, engine

A damaged air filter allows contaminat- ed air into the engine. This will cause se- rious damage to the engine.

The air filter must be cleaned after every 50 hours of operation. The oil filter must be replaced as nec- essary, or after every 500 hours of operation.

NOTE! Clean/replace the filter more often if the machine operates in dusty conditions. Remove/install the air filters as follows.

1.Disconnect the splash guard (23:G) by remov- ing the nuts (23:K).

2.Clean carefully around the air filter housing.

3.Disconnect the air filter housing by slackening off the wing nut (23:H).

4.Remove the filter (24:I) by slackening off the ridged nut (24:J).

Never direct the flow of compressed air towards the body. The penetration of air into the blood stream can be fatal.

5.Clean off any dry dirt on the filter by blowing compressed air in and out of the filter. The pres- sure must not exceed 5 bar.

Check for cracks or other damage after clean- ing. This can be visually checked against a light source.

Check that the filter’s mating surfaces are free of faults.

If the filter is damaged, it must be replaced. If the filter is contaminated by moisture/oily dirt, it must be replaced.

6.Assemble in reverse order.

Do not use compressed air or petroleum based sol- vents such as kerosene to clean the paper filter in- sert. This will damage the filter.

5.13 Air intake

See 10:W. The engine is air-cooled. A blocked cooling system can damage the engine. Clean the engine’s air intake after 50 hours of operation. More meticulous cleaning of the cooling system is carried out during each basic service.

5.14 Lubrication

All lubrication points in accordance with the table below must be lubricated every 50 hours of opera- tion as well as after every wash.
