Maintenance
Regular maintenance is the best prevention for costly downtime or expensive, premature repair. The
following pages contain suggested maintenance information and schedules which the operator should
follow.
Remain alert for unusual noises. They could be signaling a problem. Visually inspect the machine for
any abnormal wear or damage. A good time to detect potential problems is while performing scheduled
maintenance service. Correcting the problem as quickly as possible is the best insurance.
Keep your machine clean, remove heavy deposits of trash and clippings, they can cause engine
overheating as well as excessive belt wear. Clear away heavy build-up of grease, oil and dirt, especially
in the area of reservoir oil and engine combustion air; minute dust particle are abrasive to close-
tolerance engine and hydraulic assemblies.
Some repairs require the assistance of a trained service mechanic and should not be attempted by
unskilled personnel. Consult Priceless Aviation Products when assistance is needed
