Gutter Broom Pressure
Proper broom pressure is very important. Low broom pressure will cause poor sweeping. High
broom pressure will cause excessive broom wear.
IMPORTANT: Be sure gutter broom angle is correct before setting gutter broom pressure.
Correct Gutter Broom Pressure
1. Lower brooms onto the road surface and have them rotate with the sweeper stationary.
2. Stop and raise the brooms.
3. Drive sweeper off the swept pattern.
4. Inspect the pattern: If the gutter broom pressure adjustment is correct, the front outside
1/3 of the broom must be in contact with the road surface. As a rule of thumb a 9:00 to
1:00
on the driver’s side and 11:00 to 3:00 on passenger’s side pattern is preferred.
Adjust Gutter Broom Pressure
(Refer to Figure 6: Gutter Broom Assembly)
1. Loosen turnbuckle lock nut (I) on suspension turnbuckle (H).
2. To increase down pressure on gutter broom lengthen the turnbuckle, to reduce down
pressure shorten the turnbuckle. By lengthening or shortening the turnbuckle will affects
spring (D) which increases or lowers gutter broom pressure to compensate for wear.
3. Tighten lock nut (I) on suspension turnbuckle (H)
Sweeping Width
(Refer to Figure 6: Gutter Broom Assembly) also
(Refer to Figure 7: Gutter Broom Pattern)
The sweeping path width can be adjusted for a broader or narrower sweeping path.
NOTE: The wider the sweeping path the greater the possibility of damaging the broom linkages
from impacts.
Tighten bolt (K) to decrease the sweeping path and loosen to increase sweeping path.
NOTE: The wider the sweeping path the greater the possibility of streaking between the rear
broom and the main broom. A sufficient gutter broom to main broom overlap must be
maintained.
