SIDE BROOMS
The side broom’s sweeping angle is not adjustable, however the height of the side brooms can be adjusted to
compensate for wear as the brooms become worn from use. Open the top cover and turn the adjustment nut to
vary the side broom sweep height .
TO CHECK THE SIDE BROOM SWEEP PATTERN
1.
Position the machine on a smooth level surface.
2. Place the side broom lift lever in the “DOWN” position.
3. While staying in place allow the side brooms to sweep for a short period of time. (Allow enough time for the
side brooms to leave a clean footprinton the floor).
4. Place the side broom lift lever in the “UP” position.
5. Back the sweeper away from the area where the pattern was left.
6. Turn Key Switch to the “OFF” position.
7. Check the pattern to determine the floor contact area.
8. Determine if sweep height adjustment of the side brooms is necessary by comparing the floor contact area
to the diagram in Figure 16.
