Adjustments
Gutter Broom Angle Adjustments
(Refer to Figure 6: Gutter Broom Assembly) also
(Refer to Figure 7: Gutter Broom Pattern)
The proper tilt angle must be maintained for effective sweeping. If the broom is set too flat, it
will tend to throw debris back to the curb. If the broom angles are too great, streaks of debris
will be left on the pavement.
Correct Gutter Broom Angle
The broom angles are correct when the front outside 1/3 of the broom contacts the pavement.
With the brooms fully lowered, ensure the gutter broom pattern overlaps the main broom pattern.
This setting is met when the brooms are adjusted between 3º - 5º tilt angle.
The attack angles of the brooms are adjustable as well but are set at the factory and should not
require further adjustment except for special applications. Only the tilt angle may need
modification from time to time. The attack angle should be set to 3º - 5º for normal sweeping.
Adjust Tilt Angle
(Refer to Figure 6: Gutter Broom Assembly) also
(Refer to Figure 7: Gutter Broom Pattern)
1. Loosen angle adjustment lock nut (B) to allow movement of the angle adjustment
turnbuckle (C).
2. To increase the tilt angle of the gutter brooms, decrease the length of turnbuckle (C). To
decrease the angle, lengthen turnbuckle (C).
3. Once the proper tilt angle is achieved, tighten angle adjustment lock nut (B) to secure
brooms.
Adjust Front to Back Angle
(Refer to Figure 7: Gutter Broom Pattern)
1. Loosen lock nut on adjustment turnbuckle (L) to allow movement of the lower section
of the gutter broom.
2. To increase the forward attack angle of the broom to the sweeping surface, turnbuckle
must be shortened. To decrease the attack angle or flatten the broom, turnbuckle must
be lengthened. The attack angle should be set to 30
– 50 for normal sweeping.
3. Once the correct angle is adjusted, make sure the turnbuckle lock nut is tightened.
