MAINTENANCE MAINTENANCE ALWAYS USE GENUINE <strong>PARTS</strong> WHEN REPLACEMENT <strong>PARTS</strong> ARE REQUIRED. 1. Avoid exposing broom bristles to direct sunlight for long periods to avoid damage. 2. Because of the dust raised during sweeping, the tractor air cleaner should be checked daily and replaced when necessary. Hardware Check and tighten all hardware, including factory-installed hardware, before operating the rotary broom and every 8 hours of operation. TROUBLESHOOTING Debris Accumulation in Front • Reduce the travel speed. • Increase the engine rpm. • Make more than one pass. • Raise the brush to decrease the contact area. • Increase the broom angle. Uneven Wear of the Brush • Make sure there is no debris wrapped around the brush. • Check the ground pressure adjustment (see page 16) • Remove the accumulated debris under the hood. Premature Wear of the Driveline • Reduce travel speed. • Make more than one pass especially in deep, heavy debris. • Avoid ramming piles. • Lack of lubrication – lubricate more often.
