Danger!
Risk of spraying:
Pressurised contents.
☞
Always wear a suitable mask. Always take care when removing plugs and
screw connections.
Notice!
Keep the work area clean to avoid dirt on assembled parts.
Checking the product
☞
Clean the PowerTilt swivel device thoroughly before dismantling it. Clean all parts in a
washing container and dry them with compressed air. Inspect the PowerTilt swivel
device for corrosion damage before dismantling it.
Notice!
If corrosion is clearly visible, apply penetrant oil to the screws several hours before
dismantling.
Internal decompression valve
Notice!
Remove and replace the internal decompression valve only if there is reason to
suspect leakage.
Caution!
If the excavator applies too much pressure against an obstacle, this can build
up pressure in the Powertilt swivel device.
☞
The internal decompression valve is activated and the PowerTilt does not
retain its position.
Testing the hydraulic system of the machine
☞
The maintenance technician is responsible for ensuring that the machine and hydraulic
system are in correct working order. Since the hydraulic system of the machine
supplies the PowerTilt swivel device with oil, checking the system for correct function is
essential.
