If necessary, rotate the drum axle until the clevis pin hole in the axle aligns with the matching hole in the gearcase output shaft. 2. Use a clevis pin and hitch pin to secure the drum axle to the shaft. 3. Slide the recessed end of a sweeper drum assembly over the assembled axle, and then push the drum down the axle until it bottoms at the clevis pin. 4. Use a cotter pin to secure the drum assembly on the axle (see inset). The cotter pin is designed to fit tightly against the outboard end of the drum, so you may need to compress the drum face slightly during installation. 5. Repeat Steps 1-4 to install the remaining axle and drum assembly. CAUTION! The two drum assemblies are identical, but each drum must be installed with its recessed end facing toward the gearcase. 2 Break-in and Operation ALWAYSwear hearingprotective devices.

DIRECTIONOF ROTATION BEWAREof throwndebris! If the machine is used in dusty conditions, the air filter should be saturated in air filter oil (see "Oiling the Air Filter" in the operators manual that came with the powerhead). Please check and clean the air filter often and replace the filter when necessary to prevent damage. The Clean Sweep works best when its rubber fins can quickly slide or “skim” over the surface being swept. New or replacement sweeper belts tend to grip or drag on hard surfaces, and should be thoroughly broken in or “scuffed” before the broom is actually put to work. Break-in is easily accomplished by operating the Clean Sweep at full throttle for 3 to 5 minutes in loose gravel or similar abrasive material. Once broken in, the Clean Sweep will effortlessly move an amazing variety of materials, ranging from snow or standing water to heavier objects such as gravel or wood chips. Experience will help you understand the operating principles of the Clean Sweep, but safe operation must be practiced from the start. 3 Operating Techniques Operate the Clean Sweep at or near full throttle with its sweeper fins resting on the work surface. IMPORTANT! It is both tiring and unnecessary to lift or hold the fins from the work surface during sweeping. When sweeping narrow areas such as sidewalks, the Clean Sweep can be used to throw material directly ahead of the operator. Clearing wider areas may require sweeping at an angle to create windrows to one side of the path being cleared. Windrows of lighter materials often can be combined into one main row or pile for eventual pickup, while heavy or bulky material may need to be collected row-by-row. To pull debris from corners, reverse sweeper drum rotation by turning the powerhead over (throttle facing “up”). DIRECTION OF ROTATION Sweeping corners with the PowerBroom upside down WARNING! Reversing the Clean Sweep will cause debris to be thrown back toward the operator. When reversing the Clean Sweep, use lower throttle settings and beware that thrown debris may also affect your footing! OPERATION 4 Operating and Safety Tips Maintaina shallow working angle.
