6. Maintenance and Repair
Maintenance should only be performed by experienced and trained personnel.
Be sure the ventilator blade has come to a complete stop before performing any maintenance or repair.
Disconnect spark plug wire from spark plug and keep it away from spark plug.
The ventilator blade should be specially checked for build-up of material or dirt which may cause an imbalance. Excessive
imbalance can lead to accelerated wear on engine bearings and vibration. Remove ventilator guards. Clean blade and inside
housing with mild detergent and water. Do not use abrasives, sharp instruments or caustic solvents that may scratch or damage
the aluminum alloy blade.
