Whenusingthemachineataspecificheightabovesealevelandinconnectionwith certainoutsidetemperatures,theperformanceandservicelifeoftheelectricmotor is decisively affected. Under theseconditions,thereis alsoan increasedriskofhydraulicoil overheating.

Before initial start up

Check the insulation resistance

Beforeinitial start up and after a long periodof non-use, andbeforethe excavator is connected to the power supply, check the insulation resistance:

The resistance values must never be less than the minimum authorised resistances given in the instruction manual of the electric motor.

If insulation resistances are less than the minimum authorised value: Refer to the procedure in the instruction manual of the electric motor.

Check direction of rotation of electric motor

Beforeinitialoperation,orbeforerestartingtheelectricmotorafterrepairstotheelectrical system, check the direction of rotation of the electric motor. Briefly start and stop the motor, and compare the direction of rotation to the arrows marked on the motor.

Activities before starting

Caution!

It is only possible to extinguish a source of fire when this one is accessible. Before starting, unlock all locks on the panelling of the hydraulic excavator. In the event of fire, the doors can be opened immediately and the fire extinguished.

Arrangement of locks: refer to chapter Maintenance.

Caution!

The activities below involve scald or burn hazards due to the high temperature of the hydraulic oil when the machine is at operating temperature. Read the Maintenance chapter in order to get informations about carrying out these activities.

Warm-up procedure for hydraulic circuit

If the excavator is started when the exterior temperature is below 0°C, the operator must do the warm-up procedure:

Make sure that the hydraulic oil temperature is sufficient (refer to lubricating sectioninchapter5)todothisprocedure.Ifthistemperatureisnot sufficientwhena preheating system is installed on the excavator, keep preheating.

Start the electric motor and let it run without load during the first 3 to 5 minutes and make sure that no error symbols are shown on the monitoring display (refer to the functions of the display in chapter 3).

Step 1 - Open louvers and tarpaulins (if installed).

Step 2 - Carefully activate the working hydraulic circuits. Do not reach end positions of piston rod. Operate all movements at reduced speed: and repeat 10 times before moving to next cylinders: 4 times in each direction.

Step 3 - Repeat step 2 a second time.

Step 4 - Repeat step 2, with reaching end position of piston rod.
