GENERAL MAINTENANCE

AERATOR MAINTENANCE

TO KEEP THE AERATOR IN GOOD OPERATING CONDITION, PERFORM THE FOLLOWING:

•When replacement parts are required, use genuine Classen parts or parts with equivalent characteristics including type, strength, and material. Failure to do so may result in product malfunction and possible injury to the operator and/or bystanders.

•Any warning decal that becomes illegible should be replaced immediately. (See Pg. 5.)

•Do not operate equipment without shield(s) in place. Do not make any adjustments or perform any maintenance while the engine is running.

•Thoroughly clean all tines inside and out when aerating is completed and apply a light coat of oil to prevent rust on tines.

•Always lubricate Aerator each time it is put into service. Wipe off lubrication fittings before and after each lubrication. The number of lubrication fittings vary depending on model of Aerator.
