General warning
Activities which generate actual hazards (to life and limb or possible
damage to the material)
Warning of suspended load
Risk of explosion
Carry out work on electrical parts only if the atmosphere is not
potentially explosive. Work has to be carried out by a specialist for
maintenance and repairs in potentially explosive atmospheres.
Electrical component hazard, electrical shock hazard
Make sure to disconnect the system or component from the power
supply before carrying out works on electrical parts.
Do not use steam jet or high pressure cleaners for cleaning. Otherwise
electrical components may be damaged. Do not touch cables or
electrical components with wet or damp hands.
Cleaning work on energized components may be carried out by
electrical specialists only.
Risk of fire
Risk of fire and explosion when using inflammable cleaning agents.

Operating Manual
Filling of the reservoir
WARNING
Risk of hand injuries caused by the stirring paddle or shovel foot
Never reach into the reservoir or grease barrel while the pump
is running.
Lines are pressurized. Be careful when decoupling.
Observe extreme cleanliness when topping up the grease reservoirs.
Contaminated lubricant causes malfunctions and premature wear of the grease pump and
other components of the system.
Clean surroundings before exchanging or topping up
Switch off centralized lubrication system
Remove dust protective cap at the filling coupling and the dust
protective cap at the filling nipple
Couple the filling hose for P1 resp. P2 and switch on
the filling pump
When the reservoir is full, the sensor transmits an
electric signal to the control unit. Visual control is possible by
using the dipstick
When the filling pump is switched off
Disconnect the filling coupling and reinstall the dust protective
caps
Inadvertent filling with incorrect lubricant
Should incorrect lubricant have been filled, please proceed as follows:
Switch off the pump or centralized lubrication system and secure it against being
switched on.
Remove lubricant.
Clean the entire centralized lubrication system (lubricant reservoir, pump housing,
metering devices and line systems).
Fill in lubricant of correct specification.
Switch the system or pump on.
Vent lubrication system.
Inform your superior to ensure that the error won't occur again.
Inspections prior to initial start-up
ATTENTION
Risk of damage to the machine
Fill the feed lines and bearing housings with lubricant to specification and lubricate the
lubrication points by hand. Otherwise the bearing points may become damaged due to
a lack of lubricant.
LEC / en / Edition: 09/2018
Check the entire system for accordance with the intended purpose and the planning
documentation. Ensure that all parameters, characteristic values and means of
operation are present and have been correctly adjusted. If deviations are detected,
they must be remedied without delay.
In order to warrant safety and function, a person assigned by the operator must inspect certain
areas of the central lubrication system prior to initial commissioning. Report any detected
deficiencies immediately to your superior and remedy them. Deficiencies may be remedied by
an authorized and qualified specialist only.

Operating Manual
System P1: Automatic lubrication
CAUTION!
Operation by authorized and instructed personnel only!
Never exceed the admissible system pressures!
Refill clean lubricant on time!
CAUTION!
Do not interrupt the power supply (main switch of battery) while the pump is
operating.
When starting the excavator, the centralized lubrication systems are connected to the power supply
automatically. Each lubrication pump then starts a full lubrication cycle and is stopped during the preset
pause time only, etc.
The pump P1 delivers lubricant via a single-line system to the lubrication points according to Chapter
9.2 Configuration.
Regarding the control and monitoring of the system refer to: Chapter 9.2. Cabin greasing module U4-
1 or Electronic Controller
If required, the operator can force the greasing cycle: for details refer to the respective data sheets.
See the characteristics of each lubrication points: Characteristics of lubrication points on the excavator.
