5.10 Lubricating with the central lubrication system (option)
General functional description of the central lubrication system
The central lubrication system allows you to lubricate all lubrication points of the wheel
loader in one single step.
• The yellow LED comes on for 1.5 seconds upon switching on ignition to indicate
functional readiness of the controls (switch-on check). It stays lit during the entire lubri-
cation procedure.
• The integrated electronic control unit has a data memory for saving the times that have
been set or that have elapsed. The time is taken and saved if ignition is switched off
during lubrication or during a break. The remaining lubrication time or break time is
read from the memory upon switching ignition on again, and lubrication is resumed
where it was interrupted.
Time control
• Break and lubrication times can be set with the time-dependent control of the central
lubrication system. Break times are the periods between two lubrication times.
Pressing the tip switch A on the side of the pump starts intermediate lubrication at
any given time if ignition is switched on. This also serves as a functional check.
• The pump then immediately starts with a lubrication cycle. The lubrication or
break time that has elapsed so far or that has been saved is reset and starts
over again.
• A lubrication system malfunction can also be reset by pressing the intermediate
lubrication switch, and the pump restarts lubrication.
Repair work
Repair work on the central lubrication system may be performed only by authorised work-
shops!
