START UP & PROPELLING
CAUTION: OPERATOR MUST BE SEATED WITH SEAT BELT PROPERLY
SECURED WHILE ENGINE IS RUNNING.
This model of broom is hydrostatically driven. Motion is achieved by depressing the foot pedal on
the floor board to the right of center. Letting the foot pedal up will result in a braking action caused by
the hydraulic system. This is the proper method for braking on this machine. The brake pedal on the left
side of the floor board should not have to be used except in cases where the engine has died or there is
a problem with the hydraulic system.
CAUTION: BEFORE STARTING ENGINE, BE SURE PARKING BRAKE IS SET,
(PULLED ALLTHE WAY FORWARD), LEFT FOOT IS ON THE BRAKE
PEDAL AND RIGHT FOOT DOES NOT CONTACT THE CONTROL
PEDAL.
1. Turn the key switch to the start position, all the way to the right. Add fuel as necessary using the
hand operated locking throttle near the lower right side of the dash. Release the key switch when the
engine starts. Do not use ether (STARTING FLUID) in this engine, severe engine damage will occur.
2. Use the foot pedal on floor board to choose the direction of foward or reverse.
3. After the desired direction has been selected, raise engine R.P.M. to about half throttle. Release
parking brake. Slowly depress control pedal and adjust the engine to the desired travel speed. Speed
can also be varied by the distance the control pedal is depressed.
CAUTION: DO NOT REVERSE THE DIRECTION OF TRAVEL WHILE THE
BROOM IS IN MOTION. THIS WILL DAMAGE THE DRIVE
COMPONENTS AND VOID THE WARRANTY. THIS TYPE OF
OPERATION IS CONSIDERED TO BE ABUSE.
4. To stop the engine, turn the key back to the center position. The parking brake must be set prior to
leaving the operator’s seat.

OPERATION OF THE SWEEPING CORE
All functions of the sweeping core are hydraulically operated. Two control valve handles are mounted
to the right of the operator’s seat for controlling these functions. The Joystick controls the core height
up down and the right and left angle of Broom. The handle beside it controls the operation of the core
motor.
RAISE / LOWER / FLOAT DETENT
To raise the core, move the Joystick to the back, “RAISE,” position until the core is raised all the
way. The handle will return to the hold position and core height will be maintained. To lower the core
during normal sweeping conditions, move the Joystick to the front, “FLOAT DETENT,” position. The
“FLOAT” position will allow the core to maintain the ideal contact with the road while allowing it to
floatover bumps orcontours inthe road surface.This valveis equippedwith a featurecalled “POSITIVE
DOWN PRESSURE.” It should only be used under the heaviest sweeping conditions. The down pressure
adjustment is located between the hold position and the float detent. To adjust the core height downward,
slowly move the handle from the hold position to the lower position. The core will begin to move
downward. Release the handle when the desired height has been achieved.
NOTE: The operator must maintain continuous adjustment on the core while the down pressure
option is being used. This feature does not allow the core to float over contours in the road surface.
Therefore, the operator must constantly make these adjustments. If the broom core is forced to close to
the ground, the bristles will not have the “flicking “ action which is necessary to do a proper sweeping
job. This is why we recommend using the float detent during all but the heaviest sweeping conditions.
CAUTION: OVER USE OF THE POSITIVE DOWN PRESSURE FEATURE WILL
CAUSE EXCESSIVE WEAR AND SHORTEN THE LIFE OF THE
BROOM.
RIGHT / LEFT ANGLE
The core may be set at any angle from 40oleft to 40oright. Move the Joystick to the right and it
moves the core towards the right rear wheel. Toward the left the opposite. Release the handle when the
desires angle is achieved.
BROOM ON / BROOM OFF
The core motor is activated when the handle to the right and is moved to the front, “ROTATION
ON’position and turned off when the handle is moved back, “ROTATION OFF” position.
NOTE: Engine speed should be at full R.P.M. for sweeping operations. Lower engine R.P.M.’s will
exert abnormal stress on the engine and related hydraulic components which will result in a shortened
life span of these items.

1. If the broom starts to hop or bounce, the propelling speed is too high. Slow the machine down, but
maintain high engine speed. This will allow you to do a good job on the first pass and you will not
need to go over it again.
2. In areas where the dirt is caked, try to clean the sweeping surface by going over it a second or
third time. If this does not clear the dirt, use the Positive Down Pressure feature, although in most
cases, the float position will yield the best results.
3. When changing the direction of travel, for example, backing up to sweep a spot which was not
cleared the first time, always allow the machine to come to a complete stop before moving the shift
lever in the opposite direction. This will help eliminate break downs and costly down time.
4. If the dust cloud becomes so thick that your vision is obscures and you can’t see the road, use the
water sprinkling system (if installed) or stop the machine until the dust clears. If possible, angle
the sweeper so that the dust and debris is swept downwind.
5. Always wear eye protection, hearing protection and some sort of dust filter over your mouth and
nose.
CAUTION: THE OPERATOR MUST BE AWARE, AT ALL TIMES, OF ANY PEOPLE,
VEHICLES OR ANY OTHER OBJECTS WHICH MIGHT BE IN THE PATH OF
FLYING DEBRIS FROM THE SWEEPER. THE SWEEPER CAN THROW SMALL
ROCKS AND OTHER OBJECTS SEVERAL FEET. THIS DEBRIS CAN CAUSE
SERIOUS INJURY TO PEOPLE AND DAMAGE TO PROPERTY.

SWEEPING TIPS

Table of Contents

EXTENDING BRUSH LIFE
BRUSH DOWN PRESSURE
Mostproblems ofrapid wear, bristle breakageand lossare attributed toexcessive downpressure.
If the proper down pressure is used, the sweeping efficiency will improve and bristle life will be extended
considerably. More down pressure does not give a result of better sweeping. The broom gets its sweeping
action by the flicking action of the bristles.
Broce Brooms are equipped with a float detent control valve. This function should be used as
often as possible for optimum sweeping and longer brush life.
When too much down
pressure is used, the side of the
bristle is in contact with the
working surface and very little
flicking action is present to give
a good clean sweep.
Set broom down
pressure to maintain sweeping
patternas shown,approximately
5-6 inch width .
KEEPING BROOM LEVEL
Running the broom core out of level will result in a poor sweeping job and a shortened wafer
life. Check the broom core for levelness every day it is to be used.
There are three things to look for if the broom core is not level.
1. Make sure both of the rear tires are inflated to the same pressure. Both rear tires should be
the same brand and size to help in keeping the machine level.
2. Check the frame and make sure it is not bent.
3. Make sure the hanger bearing hub bolts are tightened evenly and the hub bearings are
adjusted properly.
PROPER GROUND SPEED
Rotary sweepers work best when they use a flicking action of the bristles. The broom can sweep
debris to a depth of ½ the diameter of the brush or to the point where the frame or a shield is in contact
with the debris and causes a restriction in the natural sweeping process. If the ground speed is too fast
the debris may build up in front of the brush causing a wind row effect. This wind row effect will put
excessive side pressure on the bristles and they will break off at the metal ring that holds them in place.
Always sweep at a brush rotation speed that is high enough and a ground speed that is low
enough to discharge the debris effectively and result in a clean sweeping job.
