Important Inspection Items After Reassembly

• Operate the excavator and check for unusual noise and vibrations.
• Ensure safety decals and wire harness clamps are positioned correctly.
• Verify hydraulic oil levels with the machine positioned properly:
  • Park on level ground.
  • Ensure oil temperature is between 10-30u00b0C (50-86u00b0F).
  • Check that the oil level falls within the specified range on the gauge.

Hose Volume Control Functionality

The hose volume control, attached to the control valve, acts as a damper. It helps prevent sudden pressure surges and avoid jerky starts, improving operator control. Particularly at low temperatures, the throttling effect is hindered. For cold conditions, consider removing the hose volume control to improve the damping effect, but be aware that higher oil temperatures lead to faster machine responses.
