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 

 

 

 

 

 

 

 

 

 

 

IMPORTANT

Read and observe safety warnings in front of manual.

WARNING

Unless specifically required, DO NOT have engine running when 
servicing or making adjustments to tug. Repairs or maintenance 
requiring engine power should be performed by trained personnel only.

WARNING

To prevent carbon monoxide poisoning, be sure proper ventilation is 
available when engine must be operated in an enclosed area.
