Hydraulic leak
The following are possible causes for hydraulic oil leakage from hydraulic drive unit:
• Excessive pressure.
• Dirt obstructing a seal.
• Loose or badly fitted connections.
• Damaged or broken components.
When an hydraulic oil leak is detected, identify the true cause of the leakage before remedial action is taken.
• Do not attempt to remove hydraulic components or repair the hydraulic system whilst pressured. To prevent
accidental operation, switch off power before removing any system component.

• Refer to Commander manual. Examine the Button
Sheet to identify correct function.
