Maintenance

5.12 Maintenance of attachments

Important!

Correct maintenance and service is absolutely necessary for smooth and continuous operation, and for an increased service life of the attachments. Please observe the lubrication and maintenance instructions in the Operator's Manuals of the attachments

5.13 Electric system

Warning!

Batteries can explode or cause chemical burns. A battery contains sulfuric acid and emits explosive gases when heavily discharged.



Do not smoke or use an open flame near the battery.



Do not handle the battery recklessly, causing acid to leak or spill.



Do not add circuits or electrical accessories that exceed the system capacity.



Do not connect a circuit without a correctly-rated fuse or circuit breaker.Possible equipment damage from improper battery connections.



When connecting the battery leads, make sure the poles +/– are not reversed, otherwise sensitive electric components will be damaged



Use only 12 V power sources. Higher voltages will damage the electric components.



Do not interrupt voltage-carrying circuits at the battery terminals because of the risk of sparking.



To prevent short circuits, never place tools or other conductive articles on the battery.



Disconnect the negative (

–

) battery terminal from the battery before starting repair work on the electric system.

Important!

Dispose of used batteries properly.

Service and maintenance work at regular intervals

Maintenance

Instructions concerning specific components

Cables, bulbs and fuses

Always observe the following instructions:

• Defective components of the electric system must always be replaced by an authorized expert.

• When performing maintenance work on the electric system, pay particular attention to ensuring good contact in leads and fuses.

• Blown fuses indicate overloading or short circuits. The electric system must therefore be checked before installing the new fuse.

• Only use fuses with the specified load capacity (amperage).

– see chapter Fuse box in engine compartment

on page 6-9

Alternator

Always observe the following instructions:

• Only test run the engine with the battery connected.

• When connecting the battery, make sure the poles (+/–) are not reversed.

• Always disconnect the battery before performing welding work or connecting a quick battery charger.

• Replace defective charge indicator lights immediately

Maintenance

Warning!

Battery acid hazard. The battery contains highly caustic sulphuric acid. This acid must not be allowed to come into contact with the skin, the eyes, clothing, or the machine.



When recharging and/or working near the battery, always wear goggles and protective clothing with long sleeves.



If acid is spilled, thoroughly rinse affected skin immediately with clean water and seek medical attention immediately.

Warning!

Battery explosion hazard. Lead acid batteries can generate a potentially explosive hydrogen and oxygen mixture. Batteries can explode or rupture during jump starting, particularly if the electrolyte is low or has been frozen.



Avoid open flames and sparks in the vicinity of the battery. Do not smoke.



Before jump-starting, take the battery to the dealer for appraisal by a qualified technician.



Replace a dead battery with a new one equivalent to the original.



Always disconnect the negative terminal (–) from the battery before starting repair work on the electric system.

Battery

A

is located under the cab, in front of the fuel tank. The battery is

“maintenance-free”. However have the battery checked at regular intervals to make sure the electrolyte level is between the MIN and MAX marks.

Checking the battery requires it to be removed and must be performed by an authorized workshop.

Always follow the specific battery safety instructions!

Important!

Do not disconnect the battery while the engine is running.
