INSPECTION, MAINTENANCE, AND CLEANING

        CAUTION!  Always make sure the Engine’s Power Switch is in its 
“OFF” position.  Disconnect the spark plug wire from the engine. Allow 
sufficient time for the Engine to completely cool before performing any 
inspection, maintenance, or cleaning on the Vibrator Plate and/or Engine.

2.

 

Before each use, 

inspect the general condition of the Vibrator Plate.  Check for 

loose screws, misalignment or binding of moving parts, cracked or broken parts, 
and any other condition that may affect its safe operation.  If an Engine problem 
occurs, always have the Engine immediately checked out by a qualified service 
technician
 before further use.

 

Do not use damaged equipment.

Before each use,

 check to make sure the Engine’s oil level is adequate. If 

necessary, fill the Engine’s Crankcase until the oil level is even with the Oil Fill 
Hole.

 remove all debris from the Vibrator Plate using a soft brush,

to lubricate all moving parts.
