Inspect rotor belt. Check for proper tension. Belt should deflect no more than ¼ in. (0.6 cm) under moderate finger pres-
sure ~2lbs. of force. If belt deflects excessively or if it has cracks or excessive wear, contact your local distributor for in-
structions.
Vacuum interior to remove dust and debris. Wipe interior surfaces with clean, dry cloth. Do not apply water or cleaning
solutions of any kind. Take care not to damage electronic sensors and wires.
Reattach side panel. Reattach sensor cable inside panel. Thread the cable up through the zip tie and then plug in the
cable. Now install screws, finger tight only, starting at the top and working down. Once all screws are properly started,
then use a hand tool to tighten the screws snugly. Do not overtighten. Do not use a power tool to tighten screws.

pears, refer to the explanations and solutions shown below. If these solutions do not fix the problem, contact your local
authorized service center.
NOTE: The message "POWER FAILURE" is not a system error. When this message is displayed, it indicates that
