Power Broom

Use only clean, fresh (no more than 30 days old), fuel from a reputable source.

Fill the fuel tank as shown in Figure 7; do not fill above the bottom of the fuel tank neck.

Figure 7

Important: For best results, purchase only the quantity of fuel that you expect to use in 30 days. Otherwise, add fuel stabilizer/conditioner to fresh fuel as directed by the fuel-stabilizer/conditioner manufacturer.

A broom sweeps with the tips of its bristles. When you apply too much downward pressure, the broom no longer uses its tips; the broom is now working with the sides of the bristles. This limits the flicking action of the bristles and sweeping effectiveness, decreasing the service life of the broom.

1. Drive the machine to a flat, dusty area and stop the machine.

2. With the engine running, move the throttle midway between the SLOW and FAST positions.

3. Squeeze the broom-drive control, and allow the broom to rotate for 30 seconds.

4. Release the broom-drive control, shutoff the engine, and wait for all moving parts to stop.

5. Check the area swept by the broom. The broom-sweep area should equal the full broom width and a maximum depth of 51 to 102 mm (2 to 4 inches).

   

   Figure 8

   2. Full broom width
   3. Swept area

6. If the broom-sweep area is too large, too small, or uneven, adjust the broom height; refer to Adjusting the Broom Height.

1. Drive to a flat, dusty area and stop the machine.

2. Ensure that the broom-drive lever is released, shutoff the engine, and wait for all moving parts to stop.

3. To adjust the broom height, remove and retain the pin from the adjuster sleeve and wheel tube of the caster (Figure 9).

   

   Figure 9

   2. Positions to achieve 3 mm (1/8 inch) increments
   3. Pin
   4. Adjuster sleeve

4. Raise or lower the caster wheel tube to adjust the area swept by the broom as stated in Checking the Sweeping Path.

   Note: Select any hole combination that is in alignment to place and latch the retaining pin; match the same position on the other side.

5. For finer adjustment, slide the adjuster sleeve 1 pin hole up or down on the caster wheel tube to adjust the broom height in 3 mm (1/8 inch) increments (Figure 9). Repeat steps 3 through 5 for the other caster wheel.

   • To raise the broom in 3 mm (1/8 inch) increments, slightly raise the adjuster sleeve and insert the pin into the next pin hole below the current hole used.

   • To lower the broom in 3 mm (1/8 inch) increments, slightly lower the adjuster sleeve and insert the pin into the next pin hole above the current hole used.

6. When the broom height is adjusted, secure the pin on each caster wheel, and check the broom-sweep area; refer to Checking the Sweeping Path.

Important: If the machine moves when the traction-drive lever is disengaged, check and adjust the traction cable; refer to Checking the Traction Cable Adjustment and Adjusting the Traction Cable, or contact your Authorized Service Dealer.

Pivoting the Machine with the Engine Shutoff

Squeeze both wheel-clutch levers simultaneously and pivot the machine (Figure 18).

Figure 18

1. Set the engine throttle to the FAST position.

2. Place the speed-selector lever into the desired position, and slowly squeeze the traction-drive lever (left).

   Important: Make sure that the traction drive is engaged before operating the broom; otherwise, the broom may drive the machine in the reverse direction.

3. Engage the broom by slowly squeezing the broom-drive lever (right) to the handle (Figure 19).

   

   Figure 19

   • If the engine slows down under a load or the wheels slip, shift the machine into a lower gear.

   • If the front of the machine rides up, shift the machine into a lower gear. If the front continues to ride up, lift the handles.

4. To stop the broom, release the broom-drive lever.

1. Disengage the broom and shut off the engine.

2. Wait for all moving parts to stop.

3. Push the lever down with the thumb of your right hand (Figure 20).

   

   Figure 20

4. Squeeze the left wheel-clutch lever to the handle (Figure 20) and push the broom housing to following positions.

   • 19° to the left

   • Straight ahead

   • 19° to the right

5. Once the broom is positioned, release the broom angle lever.

   Important: Ensure that the broom locks into place at one of the 3 positions.

6. Release the left wheel-clutch lever.

When working in snow, move the casters from the front of the broom arm to the back the broom hood (Figure 21).

Figure 21

5. Washer
6. Locknut

1. Support the broom.

2. Remove the 2 locknuts, 2 washers, and 2 carriage bolts (Figure 21) that secure the caster bracket to the broom arm.

3. At the back of the broom hood, align the holes in the caster bracket with the holes on the inboard side of the broom arm (Figure 21).

4. Secure the caster bracket to the broom arm with the 2 locknuts, 2 washers, and 2 carriage bolts (Figure 21).

• If the broom becomes clogged, stay in the operating position and release the traction-drive lever. While engaging the broom, push down on the handles to raise the front of the machine a few centimeters (inches) off the pavement. Then lift the handles quickly to bump the front of the machine on the pavement. Repeat if necessary.

• If you cannot unclog the broom by bumping the front of the machine, do the following:

  • Park the machine on level ground. shut off the engine, wait for all moving parts to stop, and disconnect the spark-plug wire.

  • Sharp objects can become entangled in bristles. Use gloves and caution when removing foreign objects from the broom; do not use your hands.

• In snowy and cold conditions, some controls and moving parts may freeze. Do not use excessive force when trying to operate frozen controls. If you have difficulty operating any control or part, start the engine and let it run for a few minutes.

• After using the machine, let the engine run for a few minutes to prevent moving parts from freezing. Engage the broom to clear any remaining snow from inside the housing. Shut off the engine and wait for all moving parts to stop, and disconnect the spark-plug wire. Remove all ice, snow, or other debris from the machine.

• Connect the spark-plug wire. With the engine switch in the OFF position, pull the recoil-starter handle several times to prevent the recoil starter from freezing up.

1. Lubricate the broom-angle-lock pin fitting with No. 2 lithium grease (Figure 23).

   

   Figure 23

   1. Broom-angle-lock pin

2. Remove the belt cover and the engine shield.

3. Move the speed-selector lever to the R2 position.

4. Dip a long, clean, small-tipped paint brush in automotive engine oil and lightly lubricate the hex shaft (Figure 24).

   Important: Do not get oil on the rubber wheel or the aluminum friction-drive plate as the traction drive will slip (Figure 24).

   Note: Rock the machine forward and rearward to rotate the hex shaft.

   

   Figure 24

   Note: Do not thread the cap onto the tube.

5. Remove dipstick and check oil level.

   Note: Do not operate the engine with the oil level below the Add mark or above the Full mark on the dipstick.

   Note: The oil level should be at top of the indicator on the dipstick (Figure 28).

   • If the oil level is low, perform the following:

     1. Pour the specified oil into the filler neck (Figure 28).

        Note: Do not overfill the engine with oil.

     2. Repeat steps 3 through 5.
