4 Maintenance & Fault Finding
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 anti-clockwise.
2. Turn the clutch knob either 4 clicks clockwise to tighten the
clutch, or 4 clicks anti-clockwise to loosen the clutch.
3. Use the allen key to re-tighten the clutch knob screw.
4. Check that the wheel still moves freely with the clutch off.
Note: If the wheel does not move freely, reduce the clutch tension by
turning the clutch knob 2 clicks anti-clockwise and check again
5. Check the drive’s operation with the clutch engaged.
This procedure is usually sufficient to correct a slipping or dragging
drive belt. In some cases, however, you may need to repeat the steps
to adjust the clutch further.
