The Drive Wheels won’t
turn (SELF-
PROPELLED model).

The Transmission Clutch may be out of adjustment. Adjust the Inline Adjuster located in
the Clutch Cable. See “Adjusting the Wheel Clutch” on page 27.

The Drive Chain may have broken or come off the sprockets. Remove the Bottom Shield to
investigate. See page 21.

The Drive Belt may have come off the pulleys, worn out or failed. Remove the Bottom
Shield to investigate. See page 21 and Drive Belt on page 23.

Check to see if the Wheels rotate freely in each direction. They should freewheel in the
forward direction and lock against the axle going backwards. If they freewheel backwards,
the Drive Wheel Clutches may have failed. Call 1-800-DR-OWNER (376-9637) for assistance.

If none of the above helps, visit our web site at www.DRPower.com or call 1-800-DR-
OWNER (376-9637) for assistance.
