SAFETY
DEFINITION OF SAFETY TERMS AND SYMBOLS
Throughout this manual, the terms DANGER, WARNING and CAUTION are used to indicate the degree of hazard to
personnel if proper safety procedures are not followed. These words will be used in conjunction with the Safety Alert
Symbol: a dark triangle containing a white exclamation mark.
The safety information given in this manual does not replace any safety codes, insurance needs, federal, state and local
laws.
The Safety Alert Symbol means:
-ATTENTION! - BECOME ALERT! - YOUR SAFETY IS INVOLVED!
DANGER Indicates an imminently hazardous situation, which, if not avoided,
WILL result in death or serious injury.
WARNING Indicates a potentially hazardous situation, which, if not avoided,
Could result in death or serious injury.
CAUTION Indicates a potentially hazardous situation, which, if not avoided,
May result in minor or moderate injury;
OR
May also be used to alert against unsafe practices, which may result in damage to property.
ACCIDENTS CAN BE PREVENTED WITH
YOUR HELP!
The best safety device is a careful operator. HLA and
your dealer ask that YOU be that careful, responsible
equipment operator.
Pay attention to the job at hand. Do not let your mind
lose concentration on what you are doing. No accident
prevention program can be successful without the
wholehearted cooperation of the person who is directly
responsible for the operation of the equipment.
If accidents are to be prevented (and accidents can be
prevented), that prevention will come from equipment
operators who accept their complete responsibility and
anticipate the results of their actions.
The designer, the manufacturer, and the safety engineer
all help create a safe product, but their combined e󰀨orts
can be wiped out with a single careless act by the
operator of that product.
Do not attempt to operate this equipment under the
inuence of drugs or alcohol.
YOU ARE THE KEY TO SAFETY BECAUSE:
YOU are responsible for the SAFE operation and
maintenance of YOUR rotary broom.
YOU are responsible to familiarize yourself, and anyone
else who will assemble, operate, maintain, or work around
this product, with the safety information contained in this
manual.
YOU are responsible to read ALL information contained
in this manual to any operators or maintenance personnel
who are not fully able to read the written English language.
Whether YOU read the manual as written or translate it
into another language, YOU must make certain that all
operators and maintenance personnel have complete
understanding of the full and exact contents of this
manual.

➢Ensure hydraulic hose couplings do not fall in dirt and do not become damaged in storage.
BROOM ADJUSTMENTS
Hydraulic Broom
The broom rotation direction is controlled with the auxiliary hydraulics control switch on the power unit. Speed of
rotation is controlled by engine RPM.
NOTE: Broom rotation should always be away from the operator.
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY INSTRUCTIONS (pages 3-6 of
this manual) BEFORE BEGINNING ANY BROOM MOUNTING.

- 9 -
Brush Pattern
To check pattern:
1. Move Broom to a dusty flat surface.
2. Set power unit’s parking brake and leave the engine running.
3. Start the Broom at a slow speed; then lower it so bristle tips and castor wheel touch the ground. The heal of the
bucket should be approximately 1 inch off the ground. Run the Broom in a stationary position for 10-30 seconds.
4. Raise the Broom and back away; switch off Broom and engine, remove safety restraints and remove the key. The
brush pattern left in the dust should be 2-4 inches (50-133mm) wide, running the length of the Broom.
5. The castor wheel should just touch the surface, as it is only for leveling purposes.
6. If the brush pattern is not 2"- 4" wide the broom height needs to be adjusted. Remove front bolt from “Broom Mount
Plate” on both ends of broom. Move up or down to achieve proper height, and reinstall bolts.
7. Adjust the front and side flaps to contact the sweeping surface lightly and evenly.
BROOM HYDRAULIC CONNECTION
1. Disconnect the hydraulic hose quick couplers from one another and attach the quick couplers to your power unit as per the
instructions in your power unit’s operator’s manual.
2. Carefully raise the loader arm and cycle the tilt cylinders to check hose clearances and to check any interference.
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY INSTRUCTIONS (pages 3-6
of this manual) BEFORE BEGINNING ANY HYDRAULIC CONNECTION.

- 10 -
BROOM OPERATION
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY INSTRUCTIONS (pages 3-6 of
this manual) BEFORE BEGINNING ANY BROOM OPERATION.
WARNING
EXPOSURE TO RESPIRABLE CRYSTALLINESILICA ALONG WITH OTHER HAZARDOUS DUSTS MAY
CAUSE SERIOUS OR FATAL RESPIRATORY DISEASE.
Failure to obey the following procedure will result in death or serious injury.
•Use dust suppression, dust collection and personal protective equipment during operation of
Broom.
WARNING
Failure to obey the following procedures could result in death or serious injury.
Never lift this product:
•more than a few feet off the ground OR
•to a height where visibility is obstructed, whichever is lower.
WARNING
AVOID SERIOUS INJURY.
Check for objects that could harm the operators or others if thrown by the Broom.
Remove items before sweeping.
To increase or decrease brush speed, change the power unit's rpm. Use the LOWEST speed that will
complete the job. In general, half throttle provides plenty of engine speed. The front caster wheel feature
allows the broom to follow ground contours.
USAGE:
1. Clear area of all bystanders and engage Broom only from operator’s station.
2. Avoid sweeping toward people, buildings, vehicles or other objects that can be damaged by flying debris.
3. Lower the brush to the ground.
4. Increase power unit’s engine rpm to sweeping speed.
5. Travel forward at 5mph (8kph) or less. Vary brush, engine and travel speeds to match sweeping conditions.
6. During normal sweeping operation, a small pile of material is pushed along in front of the broom. To clean up this pile at the
end of the sweeping pass, throttle down the power unit, drop the bucket cutting edge to the grade surface, and change the
hydraulic flow (operating with broom rotation in reverse), and inch forward. This action (similar to that of a broom and dust
pan), will wisp the small pile of debris into the bucket.
7. Empty the bucket by raising the sweeper above the container, then dump using the power unit tilt controls.
OPERATING TIPS:
•Follow ALL safety precautions outlined in this manual.
•Operate the sweeper on flat, level surfaces only.
•DO NOT engage or disengage the brush at a high engine speed. This damages the sweeper and motor.
•DO NOT scrape with the bucket while sweeping. It is for collection and loading and will wear prematurely if it is used for
scraping. Never operate the sweeper with the bucket less than 1" from the ground.
Dirt & Gravel
➢To keep dust at a minimum, plan sweeping for days when it is overcast and humid or after it has rained. Also, sweep so
the wind blows at your back, not directly in your face.
➢Low brush speeds and moderate travel speeds work best for cleaning debris from hard surfaces. Brush speeds that are
too fast tend to raise dust because of the aggressive brush action.
Heavy Debris
➢Travel slowly –less then 5mph (8kph).
➢Sweep a path less than the full width of the Broom.
➢When stuck-on material is encountered that cannot be removed by the rotating brush alone, the operator may simply back
over the material and lower the bucket edge to the ground and scrape the material loose.

- 11 -
BROOM STORAGE
The following storage procedure will assist you to keep your Broom in top condition.
NOTICE DO NOT STORE BROOM WITH WEIGHT ON THE BRUSH. Weight will deform the bristles,
destroying the sweeping effectiveness. To avoid this problem, place the Broom on blocks or optional
stands.
The polypropylene bristles will deteriorate in sun, high heat or flame. Do not store in direct sunlight for
any extended period of time.
STORAGE:
1. Clean Broom thoroughly; removing all mud, dirt and grease.
2. Inspect for visible signs of wear, breakage or damage. Order any parts required and make necessary repairs, to avoid delays
when starting next season.
3. Tighten all loose nuts, cap screws and hydraulic connections.
4. Lubricate grease fittings.
5. Connect hydraulic couplers together, or install covers, to protect hydraulic system from contaminates.
6. Retouch all unpainted and exposed areas with paint to prevent rust.
7. Replace decals, if damaged or are illegible.
8. Store Broom in a dry, protected place, with a cover, if possible. Leaving attachment outside will materially shorten its life.
REMOVING FROM STORAGE:
1. Remove all protective coverings.
2. Check hydraulic hoses for deterioration and replace if necessary.

- 12 -
BROOM MAINTENANCE
Regular maintenance is the key to long equipment life and safe operation. It is very important that these
maintenance functions be performed as described below.

•Wear safety glasses and use metal or wood when searching for leaks. Do not use your hands.
Steam-clean the power unit before any installation is made to the hydraulic system. Remove any attachment from the power unit
and position on a level surface.
TO REPLACE BRISTLES
Wear heavy leather gloves (wire bristles are sharp and will puncture skin).
1. Set the Broom on low blocks or stands. Block the brush core separately.
2. Remove the end cap bolts and remove cover. (Keep all bolts for later reinstallation).
3. Remove bolts which hold motor pot.
4. Motor should slide straight out. The drive plate is not fastened to the rotor and should slide out with the motor.
5. Repeat at other end.
6. Move rotor away from Broom and undo 6 bolts holding end cap on the rotor.
7. Slide old bristles off core. (May need to set rotor on end weight or tie down to the floor and use a hoist to pull bristles off
one row at a time). Take care not to damage the core.
8. To reassemble: slide new bristles on frame. Note: locate drive pins on each side of rotor flat bar. Orient waves on bristle
core so the high sides come together. Bristles alternate, one poly and one steel.
9. Reinstall end plate with the six bolts and tighten.
10. Check drive plates on motor. They should be pushed all the way back on the motor shaft. (They are not set screwed on the
motor shaft)
11. Align the rotor on the sweeper frame and insert motor with the drive plates. Drive pins should enter drive holes in the rotor.
Start the pot mount bolts –do not tighten at this point.
12. Repeat step #11 on other end.
13. Tighten bolt at this time.
14. Replace end cover and bolt securely.
WARNING
Hydraulic fluid under pressure can penetrate skin, resulting in serious injury or death.
Always relieve hydraulic pressure before disconnecting lines.
WARNING
Before servicing the loader, remove the attachment and make certain the lift arms are lowered to their
lowest position or that the arms are supported by the mechanical lock up devices (if the machine is so
