[. . . ] NOTE: Adjusting for greater stability will shorten the length of the cores you pull. You will gain greater side-to-side stability (see below “Operating on Hills. ” Adjustments for greater stability will also improve maneuverability during aeration. ) TURNING AND MANEUVERING THE AERATOR Gradual maneuvering while aerating can be accomplished by simply guiding the machine. We recommend that you adjust your engine’s speed control to allow for a comfortable walking speed. This will also help you maintain 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 two methods of turning can be used. Select the safest and most comfortable method for the conditions you face: (A) Release clutch control handle, pull up rear wheel control handle, then pivot machine on rear wheels to turn. (B) Release clutch control handle, lift handle bar and pivot machine on front wheel. WARNING: THIS METHOD IS NOT RECOMMENDED WHEN OPERATING ON HILLS (See next section). OPERATING ON HILLS WARNING - DO NOT OPERATE ON HILLS EXCEEDING 35% GRADE. Be aware that when operating on hills the tilt of the aerator will cause the machine’s center of gravity to shift to the downhill side of the machine. Under these circumstances you may experience: (A) The need to exert a greater effort to steer and maintain the balance of the machine. Due to the shifted center of gravity the downhill tines will penetrate to the maximum depth, while uphill tines may not. WARNING: IN EXTREME SITUATIONS (VERY STEEP HILLS) THE MACHINE MAY BE SO UNBALANCED, THAT IT MAY PRESENT THE DANGER OF ROLLING OVER. Figure 6 Figure 7 12 Figure 8 Maintenance and Service Instructions When operating on hills you should consider the following: (A) Operate the machine up and down the hills rather than across them. (B) Use the rear wheel depth/stability control knob to set the rear wheels for extra stability. This can be a great benefit when you do choose to run the aerator across a hill. An added benefit of using the rear wheel depth control when aerating across a hill is that you will improve the consistency of the cores pulled from the uphill tines when compared to those pulled by the downhill tines. (C) Removing the downhill weight reduces roll-over risk and maintains consistent core plug length. (See Figure 8) (D) Remove remaining weight from downhill side to uphill side after each pass when operating across hills. WARNING: NEVER DISENGAGE TINES FROM GROUND WHEN TRAVELLING UP OR DOWN HILL. ONLY DISENGAGE ON FLAT SURFACE. TRANSPORTING THE HUSQVARNA AERATOR MODEL AR19 and AR25 The removable weights are for side hill stability and tine penetration as applicable. With the weights in place, these models are designed for easy loading and unloading on ramps and trailers. Use engine power to load unit. Maintenance and Service Instructions CLEANING AND WASHING Regular cleaning, washing and lubricating will prolong the service of your machine. [. . . ] Replace the chain following procedures in section “Chain Removal and Replacement. (see page 16). Adjust chain per section “Adjusting Chain Tension” and replace drive guard. Lower the rear wheel control handle to let the aerator rest on the tines. Turn the rear wheel depth/stability control knob to adjust the rear wheels for minimum depth clockwise (more stability).
