Wheel drive
Routine maintenance
After each trip, flush inside the drive unit by inserting a hose pipe in the free slot
on the back cover.
Cleaning the wheel drive
CAUTION:
Do not use mineralbased solvents (such as WD40) to lubricate or
clean the wheel drive as they will damage the material.
We recommend that you complete the following steps each season to prevent the
buildup of salt on the wheel drive bearings and drive belt:
1. Remove the wheel drive from the wheel:
• remove the wheel from the pedestal
• remove the spoke clamp screws
• remove the wheel drive front cover
2. Check inside the drive unit for any signs of damage.
3. Thoroughly flush the wheel drive interior with fresh water to remove any salt
buildup on the bearings and drive belt.
Do not lubricate any part of the wheel drive. It is designed to run
without lubrication.
4. Replace the front cover then fit wheel drive back onto the wheel.
5. Fit the wheel and wheel drive back onto the pedestal.
6. Clean the wheel drive case (using mild detergent if necessary), then flush
thoroughly with fresh water.
Adjusting the clutch
You need to adjust the clutch if the drive belt slips in Auto mode or drags in
Standby mode. In normal use, you can tell if the clutch is slipping if the motor
operates but the drive does not turn the wheel.
To adjust the clutch, first make sure that the autopilot is in Standby mode and the
clutch is disengaged. Then:
1. Use a 3 mm allen key (supplied) to loosen the clutch knob screw about 2 turns
anticlockwise.
2. Turn the clutch knob either 4 clicks clockwise to tighten the clutch, or 4 clicks
anticlockwise to loosen the clutch.
3. Use the allen key to retighten the clutch knob screw.
