5.4Lubricants and operating fluids

5.4.1General information on changing lubricants and operating fluids

Note

The quantities given in the lubrication and operating material chart and on the lubrication chart in the cab are only guide values.

After each oil change or refill, check the level in the relevant unit.

Note!

Adhering to regulations for lubrication, level checks and operating material changes guarantees a high degree of reliability and a long service life for the machine. It is particularly important to adhere to the oil change intervals and use the specified type of lubricant.

Observe the following when using and checking lubricants and operating fluids:

Note!

Cleanliness is of the utmost importance when changing oil. Clean all filler plugs, filler covers and drain plugs and their surroundings before opening.

For preference, drain off oil when it is at operating temperature. Ensure that old oils are collected and disposed of in an environmentally acceptable manner using the removable oil filter cartridges.

Danger!

When checking and changing lubrication and operating materials, ensure that the following precautions are adhered to:

Unless otherwise indicated, carry out all work on the machine on level, solid ground and with the electric motor switched off.

Whenever you reach into the electric motor compartment, always secure the cover and side doors against accidentally falling back or closing.

Do not smoke and avoid naked flame.

Turn the main battery switch to position 0 (off) and remove the ignition key.
