2.Make sure the rear tires are in the down position (tines not touching ground). Slowly pull back on control handle(s). (See Fig. 1.) Control Handle (Left Side) Lowering Handle Fig. 1 3. Move Aerator to the work area. (See “Transporting Aerator” section.) 4. Upon reaching the work area, release control handle(s) and push down on lowering handle (see Fig. 1) putting tines in the turf. 5. Pull back slowly on the control handle(s) to begin aerating. 6. For maximum tine penetration into turf, apply downward pressure on handle. 7. Models CA-18, TA-19D & TA-26D: At the end of aerating run, release control handle and lift up on lowering handle. Turn Aerator around and repeat steps 5 and 6. 8. Models TA-17 & TA-25: These models have two control handles designed so it can be steered around corners, obstacles, etc. By pulling back only the left control handle, the Aerator will turn left, by pulling back only the right control handle, unit will turn right. Pull both control handles back to go straight. 9. When finished aerating, lift up on lowering handle to move wheels into transport position. (See “Transporting Aerator” section.) 10.

Pulley Guard Pulley Guard 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. Model CA-18 - Qty 2, one in each rear wheel assembly. Models TA-19D/TA-26D (water drum models) - Qty 3, one in each rear wheel assembly and one on the idler/clutch arm pivot bearing. (See Fig. 2.) Models TA-19/TA-26 (front tire models) - Qty. 5, one in each wheel assembly and one on the idler/clutch arm pivot bearing. (See Fig. 2.) Models TA-17D/TA-25D - Qty. 4, one in each wheel assembly and one in each idler/clutch arm pivot bearing. (See Fig. 2.) Idler Clutch Arm (Right Side) Fig. 2 • Keep drive belt(s) free of oil and dirt. Models TA-17D/TA-25D - If belts slip due to normal belt stretch, engine can be adjusted forward within slotted holes to tighten belts. • Check roller chain(s) for wear. Apply a light coat of No. 30 oil or penetrating chain lubricant to keep the chain(s) clean and in proper running order. • Check roller chain(s) for tightness. Follow these steps: Model CA-18 (See Fig.3.) 1. Disconnect spark plug. 2. Take off pulley guard by removing two nuts and lock washers. 3. Loosen nut (B) by turning counter-clockwise until nut comes in contact with head of bolt (A). 4. Tighten bolt (A) until chain is tight between front axle sprocket (D) and tine assembly sprocket (E). (See Note Opposite Page) 5. Retighten nut (B) by turning clockwise against lock washer (C). 6. Replace pulley guard, nuts and lock washers and retighten nuts. A Fig. 3 B C D E Main Frame Top Flat (Left Side) Main Frame (Left Side) Fig. 4 Model TA-17/TA-19/TA-25/TA-26 (See Fig. 4.) 1. Disconnect spark plug. 2. Take off pulley guard (see Fig. 2) by removing bolts, etc. which 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. SAFETY DECALS 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: Excessive roller chain tightness will shorten the life of the bearings. Chain(s) should have movement of 0.18 in./4mm free play back and forth at center point between front drive sprocket and rear tine assembly sprocket. ENGINE MAINTENANCE (Refer to engine manufacturer's owners manual) Check engine and gear reduction case oil level with engine resting in a level position. Inspect air filter element and replace if necessary.
