SWEEPING GUIDELINES
For best sweeping results, please observe the
following recommended guidelines:
1. Sweep only with the tips of the brush
bristles. This will provide maximum “flick”
sweeping action. Control of sweeping action can
be obtained by using the Brush Down Pressure
Control Valve.
2. The right combination of ground speed to
brush speed will correct ineffective sweeping. For
heavy sweeping, slow the ground speed and
increase the brush RPM by increasing engine
RPM.
3. Sweep only with the Speed Selector
Switch (item 4) in LOW Speed.
4. To get an ideal brush height setting,
sprinkle some sand under the brush and engage
the brush with the machine in a stationary position.
When the brush is raised, there should be a 2" to
4" wide clean swath under the entire length of the
brush.
5. For most normal sweeping operations, the
FLOAT position works best. Practice will help the
operator achieve the most effective operation of
the broom.
6. Keep the rubber brush apron, located in
front of the brush, in good working order and in
place while sweeping. The brush apron protects
the front of the broom, as well as oncoming traffic
and bystanders from flying debris.
7. Water Spray System - In certain
conditions, it may be necessary to sweep using
the optional Water Spray System to control dust.
This system consists of a 150 gallon poly tank, an
electric pump, and a corrosion resistant spraybar
and piping system. The pump is turned on by a
switch on the operator's dash panel (item 7, Figure
3-B).
SHUT DOWN
When it is necessary to leave the ROSCO Broom
for any extended period of time:
1. Place transmission lever in neutral.
2. Stop rotation of the brush and use
mechanical brush lift cylinder lock to secure brush
in the raised position. This will prevent a flat spot
from forming on the brush bristles. Be sure to do
this if the unit will be parked for an extended
period.
3. Set the Park/Emergency brake.
4. Idle the engine a few minutes before
shutting it down.
5. Remove the ignition key to prevent
unauthorized operation.
6. Lock any optional panels, cab doors, spare
tire etc. before leaving the machine unattended.
This will help prevent theft and/or vandalism while
machine is not in use.
