9. Trouble shooting
9.1 Hydraulic windlass
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.
9.2 Hydraulic question & answer
Windlass will not start
1. No power to Commander (Powerpack)
• Check unit is switched on
• Check electrical connections to Commander
• Check fuses & safety cut-outs
2. Insufficient hydraulic fluid
• Check Commander fluid level.
3. Incorrect electrical or hydraulic connections
• Refer to your Lewmar Commander manual
• See the button sheet for correct function
identification.
Windlass motor is running but the windlass
is not working
1. Check the drive between the gypsy and capstan
(friction drive or dog drive).
2. Check the drive sha between the hydraulic motor
and windlass gearbox.
Windlass runs very slowly
1. Check sufficient flow is being provided by the hy-
draulic system as windlass speed is directly related
to hydraulic oil flow.
• Refer to lewmar Commander fault finding.
2. Hydraulic pipes connected to the wrong motor port.
• Swap hydraulic connections on the winch motor.
3. Deck switch connected to wrong function.
• Refer to Lewmar Commander manual.
Windlass does not pull sufficient load
1. Check sufficient flow is being provided by the hy-
draulic system as windlass speed is directly related
to hydraulic oil flow.
• Refer to lewmar Commander fault finding.
2. Hydraulic pipes connected to wrong Commander
function.
• Refer to Commander manual. Examine the Button
Sheet to identify correct function.
3. Sharp bends or kinks in the hydraulic pipes starving
the winch of fluid.
• Check pipe runs for sharp bends or kinks: Minimum
bend radius is 6”
(150mm).
4. System pressure too low.
• Refer to fault diagnostic charts in the Commander
manual.
