Hydraulic Oil Fill Level Pre-warning

Component

Hydraulic unit

Action

Check hydraulic equipment for tightness, replenish oil

The hydraulic cycle is a closed system where only little of the hydraulic oil may be lost through leakage. Substantial oil loss indicates leakage.

Leakage oil can damage your equipment and the environment.

Consumable

Hydraulic oil HLP 46 to DIN 51524, Part 2 (ISO-L-HM 46 to ISO 6743, Part 4) Purity class ISO 4406-18/16/13

Disimilar lubricants can contain various additives that might not be compatible. To rule out incompatibility between the lubricants, disimilar lubricants must not be mixed. If you have any questions, please contact your lubricant supplier.

For structure of the hydraulic system, see media diagram (MP).

Inspection of Hydraulic Equipment

Please observe chapter 4.2 "Special safety measures" when entering or leaving the machine. Danger to life within the traversing range of the gantry loader. Before climbing onto the machine, always move the portal loader to its parking position, switch off and secure to prevent it being switched on again. Do not remove gantry loader padlock before end of work or before removing the ladder. Proceed with caution if a tool is placed in the tool spindle whilst you are working within the work area.

Step 1:

Machining unit traversed into support position.

Step 2:

Loading hatch closed.

Gantry loader in parking position, switched off and secured against being switched on again.

Step 3:

Maintenance area safety door opened and secured to prevent closing.

Step 4:

Work area safety door open and secured to prevent closing.

Step 5:

Machine switched off at main switch and secured against being switched on again.

Step 6:

Compressed air shut-off valve closed and secured to prevent opening.

Step 7:

Machining unit protected from falling by supports.

Step 8:

Check all equipment components for leakages and visible external damage:

  • Hydraulic reservoir
  • Pipes and hoses
  • Duct unions
  • Pumps
  • Hydraulic blocks
  • Filters
  • Valves
  • Pressure switches
  • Cylinders

Repair leakages and damage immediately. Do not operate machine with damaged equipment!

Step 9:

Remove support from the machining unit.

Before closing the maintenance openings and safety doors, ensure that nobody is behind the guard panels and doors. Close maintenance openings and safety doors.

Step 10:

Open compressed air shut-off valve.

Filling oil

Step 1:

Screw off filling strainer cap.

Step 2:

Fill with oil through filling opening in filler filter up to the max. mark on the oil level indicator.

Step 3:

Screw down the filter cap of the filling strainer.

Step 4:

Turn on machine on at the main switch.

Step 5:

Switch on motors. The hydraulic unit will run.

Step 6:

Run machine for a few minutes.

Check hydraulic reservoir for leakage.

Step 7:

Check oil level at the oil level indicator. Fill with oil up to maximum mark.

Step 8:

Remove gantry loader padlock.
