Maintenance WARNING While maintenance or adjustments are being made, someone could start the engine of the towing machine. Accidental starting of the engine could seriously injure you or other bystanders. Remove the key, engage parking brake, and pull the wire(s) off the spark plug(s) of the towing machine before you do any maintenance on the aerator. Also push the wire(s) aside to prevent contact with the spark plug(s).
Checking the Main Arms Adjusting the Springs The 6 main arms pivot freely horizontally and vertically to allow the unit to follow the contour of the ground. A bronze bushing is pressed inside the pivot holes between the main arm and mainframe. The bronze bushing is 3 mm (1/8 inch) longer than the thickness of both plates combined. Tighten the 5/8 x 2 inch bolt against the bushings, not the arms, to allow it to pivot freely (Figure 12).
Checking the Tines Storage To obtain maximum aerating performance, always check the tines for wear before every use. Severely worn tines are easy to bend or break and leave the cores in the ground. See Figure 13 for examples of tine wear. 1. Raise the tines. 2. Stop the towing machine, shut off the engine, engage the parking brake, and remove the key. 3. Remove dirt and grime from the entire aerator. Important: You can wash the aerator with mild detergent and water.
