SAFETY PRECAUTIONS
1. Keep all shields in place.
2. Stop machine, turn o󰀨 engine and remove key to repair or clean.
3. Keep hands, feet, and clothing away from power driven parts.
4. Keep o󰀨 of machinery unless a platform is provided.
Do not crawl on equipment.
5. When equipment becomes disabled, shut o󰀨 power before attempting repairs.
6. Check for hydraulic leaks with a piece of paper and not your hands.
Hydraulic oil under pressure can cause serious injury!
BE A SAFE OPERATOR BY
THINKING BEFORE ACTING AND
BY READING YOUR OPERATORS
MANUAL.
AVOID ACCIDENTS
Most accidents, whether they occur in industry, on the farm, at home, or on the high-
way, are caused by the failure of some individual to follow simple and fundamental
safety rules or precautions. For this reason, most accidents can be prevented by
recognizing the real cause and doing something about it before the accident occurs.
Regardless of the care used in the design and construction of any type of equip-
ment, there are many conditions that cannot be completely safe guarded against
without interfering with reasonable accessibility and e󰀩cient operation.
A careful operator is the best insurance against an accident.
The complete observance of one simple rule would prevent many thousand serious
injuries each year.
Never attempt to clean, oil, or adjust a machine while it is in motion!

SAFETY PRECAUTIONS
Read this manual completely. It contains information on safety and maintenance
procedures which must be followed to insure years of trouble free service.
BEFORE OPERATING THIS MACHINE
READ AND UNDERSTAND THE FOLLOWING
WARNING LABELS BEFORE OPERATING THIS MACHINE
WARNING STATEMENTS
The seat belt and roll over protection structure were designed to be used together to
prevent operator injury in the event of an accident. The seat belt must be worn at all
times in order to hold the operator in place so that the roll bar can protect the operator. Adjust
the slack out of the seat belt by pulling the unused portion of the belt to the left. The belt should
t snug over the operator’s hips.
Although a high travel speed is available with the Broce Broom, we caution all operators to use
good judgment, especially on rough terrain.
OPERATOR MUST BE SEATED WITH SAFETY BELT ADJUSTED
PROPERLY & SECURE WHEN ENGINE IS RUNNING.
TRAVEL SPEED MUST BE GOVERNED BY
GOOD JUDGMENT. DO NOT OVERSPEED

BROCE FMJ470
The operator must be aware at all times of any people, vehicles,
or any other objects which might be in the path of ying debris
from the sweeper. The sweeper can throw small rocks and other
objects several feet. This debris can cause serious injury to peo-
ple and damage to property. Always check that the area around,
and in front of the broom core is free of obstructions before
adjusting the broom angle or activating the core.

MACHINE OPERATION
The Broce Broom is hydro-statically driven. The directional control is achieved
through the use of the Forward & Reverse pedal, located near the operator’s foot.
Arrows on the pedals indicate direction of travel. Rate of travel is governed by the
distance the pedal is depressed and the throttle position. The pedal will return to
neutral when the pressure is released.
Familiarize yourself with the following controls before operating this machine.
1) Brake pedal
2) Forward Pedal
3) Reverse Pedal
4) Broom on/o󰀨
5) Throttle
6) Parking brake (lower left side of seat)
7) Ignition switch
8) Two speed switch
9) Broom position Joystick

MACHINE OPERATION
Prior to initial startup of the machine each day, the following inspection checks must
be performed:
1. Visually inspect the entire machine for damage and uid leaks. Repair
critical items before machine is used.
2. Check all uid levels; engine oil, radiator, and hydraulic reservoir, etc.
Fill uid reservoirs if necessary.
3. Check wheels and tires for excessive wear or damage; also check air
pressure and lug nut tightness.
4. Seat belt, core cover, and rubber rock guard should be installed and serviceable.
5. Lights, windshield wipers, reverse alarm, horn, etc. must be in operating condition.
6. Test brakes before operating this machine. Refer to BRAKES area in the
MAINTENANCE Section in this manual for details.
7. Check water system lters, nozzle screens and cycle system.
Any defects or damage found during this inspection must be repaired before
operating this machine.
MACHINE STARTUP
1.Before starting the engine, be sure the parking brake is set (pull handle up to
vertical position). The brake pedal should be depressed and the right foot is not
on a control pedal.
2. Turn the key switch to the starting position (all the way forward). Add fuel as
necessary using the hand operated throttle near the operator’s right hand. Release
the key switch when the engine starts.
Do not exceed 1500 RPM until the hydraulic uid has warmed up.

MACHINE OPERATION
Choose the desired gear using the two-speed switch located on the right-hand
side of the dashboard. Low gear is normally used while sweeping in order to
maintain su󰀩cient RPM, to run the hydraulics. Leave the two-speed in Low
gear until the operator is familiar with the machine. High gear is used for travel
only. Shifting from Low to High can be accomplished at any speed; however, shifting from
High to Low should be done at a speed lower than 5 mph. Shifting at higher speeds can
damage the drive motor. Optimal sweeping is normally achieved at manufacturer’s recom-
mended engine speed of 1800-2000 rpm in Low gear with forward travel speed of 2 ½ -5
mph.
After gear selection, raise engine RPM to about half throttle. Release parking
brake. Slowly depress a control pedal in the desired direction. Engine speed may
be adjusted to obtain desired travel speed.
Do not over speed! Although a high rate of travel is available with a Broce
Broom, we caution all operators to use good judgment, especially on rough
terrain.
If the control pedal is released while traveling, the machine will slow down
rapidly. This is called “Dynamic Braking”. Using Dynamic Braking at low
speeds is ne as long as the operator is ready to use the brake pedal if needed.
Do not reverse the direction of travel while the broom is in motion. This could
damage the drive motor and cause brush distortion and imbalance.
The core should be in the raised position and the lift cylinder safety collar
should be placed on the lift cylinder. This prevents the core from drifting down
to the ground and creating a “at spot” in the brushes while the machine is
parked. These at spots can cause the broom to bounce or hop while sweeping.
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..

SWEEPING CORE OPERATION
RAISE/LOWER
To raise the sweeping core, position and pull the
joystick to the “UP” position until the core is raised all the
way. The joystick will return to the center position and
core height will be maintained.
To lower the core during normal sweeping conditions,
push the joystick to the “DOWN” position until the core
reaches the desired position.
The gure shows the optimum broom height for most
sweeping conditions. Using the proper height will also
extend the life of the broom.
ANGLE OPERATION OF BROOM
The broom core may be set at any angle from 37 left to 37 right, simply moving
the handle in the corresponding direction. Release the handle when the desired
angle is achieved.
BROOM ON/OFF
The Broom Core motor is activated when the switch is moved to the “BROOM ON”
position.
SIDE TO SIDE OPERATION OF BROOM
The sweeper is equipped with a side shift mechanism which allows the broom to
move 14” to the left or right. This function is activated with the side shift joystick.

MACHINE OPERATION
SWEEPING TIPS
Optimal sweeping is normally achieved at manufacturer’s
recommended engine speed of 1800-2000 rpm in Low gear with
forward travel of 2 ½ - 5 mph.
If the broom starts to “hop” or “bounce”, the propelling speed is too high, reduce
the forward travel speed, but maintain high engine speed. Slowing the forward
travel speed of the machine down will help prevent you from having to make a
second pass over the sweeping area with the broom.
In areas where the dirt is “caked”, try to clean it by going over it a second or
third time.
• When changing the direction of travel, allow the machine to come to a
complete stop before moving the directional control pedals. Failure to com-
pletely stop the machine before changing direction can cause premature
failure of the drive components.
• If the dust cloud becomes so thick that it obscures your vision, use the wa-
ter sprinkling system or stop the machine until the dust clears. If possible,
angle the sweeper so that the dust and debris is swept downwind.
• Ensure that the operator of the machine is properly trained and follows all
safety procedures described in this manual.
