OPERATION Rear Wheel Adjustment The rear wheel depth/stability control knob allows adjustment for better stability and maneuverability when the knob is turned in a clockwise rotation Adjustments for depth are made by turning the knob counterclockwise. This adjustment determines the length of the cores pulled by: Adjusting the rear wheels to a desired level to control the penetration of the tines to within a fraction of an inch. With the rear wheels in the "fully up" position, maximum tine penetration is gained. Pushing down on the machine's handle bars puts most of the weight of the machine on the tines. This results in pulling the longest cores. NOTE: Adjusting for greater stability gives greater side-to-side control and will improve maneuverability during aeration. (See Operating on Slopes.) Adjustments for stability will shorten the length of the cores pulled. WARNING! This method is NOT recommended when operating on slopes. 8060-008 Control depth and stability with rear adjustment knob CAUTION! NEVER cross hard objects or surfaces (sidewalks, driveways, stepping stones, etc.) with tines down. Turning and Maneuvering Gradual maneuvering while aerating can be accomplished by carefully guiding the machine. It is recommended to adjust the engine's speed control to allow for a comfortable walking speed and maintaining complete control while working in tight spaces. Adjusting for more stability (with the rear wheels lowered, reducing tine penetration) will make turning easier. When reversing direction or making sharp turns, select the safest and most comfortable method for the conditions you face: • Release clutch control handle, pull up rear wheel control handle, then pivot machine on rear wheels to turn. • Release clutch control handle, lift handle bar and pivot machine on front wheel. WARNING! DO NOT operate on slopes exceeding 35% grade. WARNING! In extreme situations (very steep slopes) the machine may be unbalanced and present the danger of rolling over. 12
