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 bystand-
ers.
• 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 com
-
pleted 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 num
-
ber of lubrication fittings vary depending on model of Aerator.

attach it to the frame.
3. Loosen the bolts, nuts, lock washers, and flat washers (Key 4) to
allow movement of the pillow block bearings only (Key 5). Loosen
nuts only, do not remove.
4. Loosen and unthread the two 5/16’’ nuts (Key 2) down to top of
chain tightening bracket (Key 3).
5. Turn the tap bolts (Key 1) evenly clockwise so jack shaft stays
level with frame until chain(s) is/are tight.
6. When adjustment is complete, retighten the bolts (Key 4) on the
pillow block bearings (Key 5) and replace the pulley guard and
fasteners.
NOTE
