5.18 Central lubrication system (option)
Grease-based central lubrication system with 12 lubrication points.
Not in connection with triple articulation boom (option).
Function
The green LED illuminates for about 1.5 sec once ignition is switched on to indicate readiness.
Pressing the push button on the pump’s motor housing switches on the pump and starts
the lubrication cycle. The pump drive motor is switched off and cycle time begins once
lubrication time is over.
All further lubrications start automatically according to the cycle time set.
Lubrication time is stopped and saved if ignition or lubrication is switched off during cycle
time. The data is read from the memory upon switching ignition on again, and lubrication is
resumed where it was interrupted.
Pressing the push button on the motor housing or on the instrument panel starts intermedi-
ate lubrication if ignition is switched on.
