Safety ROSCO - A LeeBoy Company
RB48 BROOM
2.4
6. Do not allow riders on the broom when
transporting. Death or serious injury can occur if
riders fall off or under the machine while it is in
motion.
7. Clean reflectors and lights before
transporting to help avoid collisions.
8. Do not tow the broom, except to remove it
from the road or load it on a trailer, unless
equipped with optional tow package.
STARTING AND STOPPING
1. Walk around the broom and be sure to warn
all personnel in the area before starting the broom.
Be sure the area is clear before starting. Death
or serious injury can occur to bystanders from
being crushed under a moving machine or being
hit by debris.
2. Adjust, secure and latch the seat and fasten
the seat belt before starting the broom. Start or
operate the machine only from the operator's
seat.
3. Be sure the parking brake is applied and the
Forward/Reverse control is in the neutral position
before starting the broom.
4. Do not bypass the neutral-start system.
The neutral-start system must be repaired if it
malfunctions.
5. Do not operate the engine in
an enclosed area without adequate
ventilation. Exhaust gases contain
carbon monoxide, an odorless and
deadly poison.
6. Park the broom on level ground whenever
possible. Apply the parking brake. On grades,
park the broom with the wheels securely blocked.
7. Before dismounting from the unit, place the
Forward/Reverse handle in neutral, turn off all
accessories, set the parking brake, shut off the
engine and remove the ignition key.
SAFETY
6. Wear appropriate ear
protection when exposed to loud
noise for prolonged periods of time.
Permanent loss of hearing can result
from prolonged exposure.
7. Do not hurry! Use recommended hand
holds and steps with at least three points of
support when getting on and
off the broom. Keep steps,
floor, hand holds and controls
clean and free from grease.
Face the machine when
climbing up and down and
never jump off or dismount
while the machine is in motion.
PRE-OPERATING
1. Follow the pre-start instructions in the
Operations Section of this manual before
operation. Be sure all controls and gauges are
operating properly before starting a job. Do not
operate the broom if any of the warning buzzers /

to or during operation, shut down the broom and
report the problem to a supervisor.
2. Keep all hydraulic lines, fittings and couplers
tight and free of leaks. Leaking fittings are a fire
hazard. Hydraulic fluid under pressure can pierce
skin, causing serious injury or toxic reaction. Do
not feel for hydraulic leaks with your hands.
3. Clear the area of people before starting or
operating the broom. Death or serious injury can
occur to bystanders from being crushed under a
moving machine or being hit by debris.
4. Know and understand the job site traffic
flow patterns and obey flagmen, road signs and
signals.
5. When transporting the broom, know and
use all required signal devices. Use tail lights,
slow moving vehicle signs and warning beacons
when on public roads. Provide an escort when
necessary.

ROSCO - A LeeBoy Company Safety
2.5
RB48 BROOM
SAFETY
BRAKING
1. The operator must become accustomed to
using the hydrostatic transmission to assist in
braking. This is best done by moving the Speed/
Direction joystick into the neutral position before
applying the service brake with the foot pedal.
2. The service brakes alone are not sufficient
to stop the broom if it is in forward or reverse drive
mode.
3. Stopping distances must be anticipated for
all conditions. If stopping on a grade, the distance
needed to come to a stop will be longer the
steeper the grade. Familiarize yourself with these
variables so you can anticipate when a longer
stopping distance is required.
OPERATING
1. Wear the seat belt when operating the
broom to maximize the protection capability of the
ROPS cab.
2. Know and use the hand signals required for
each job and know who has the responsibility for
signaling.
3. Keep hands, feet, hair and
clothing away from moving parts.
Death or serious injury can occur
from entanglement in moving parts.
4. Watch for bystanders and never allow
anyone to reach into the broom while it is
operating.
5. If any of the controls such as steering,
service brakes or engine, fail during operation,
stop the broom immediately. Apply the parking
brake, turn off engine and block the wheels until
the unit can be repaired or safely towed away.
6. Place all controls in neutral, stop engine, set
park brake, remove ignition key and wait for all
moving parts to stop before servicing, adjusting,
repairing or unplugging. Death or serious injury
can occur from entanglement in moving parts.
7. Do not go under the broom when the engine
is running. Death or serious injury can occur if
one becomes crushed by or entangled in moving
parts.
8. After servicing, be sure that all tools, parts
or servicing equipment are stored properly.
9. Reinstall safety devices, guards or shields
after adjusting and/or servicing the machine.
10. When traveling down hill, put the broom in
"low" range and keep engine RPM at maximum.
11. Drive the broom at speeds compatible with
road and weather conditions. Special care should
be taken on slopes, rough ground or when turning.
Avoid hazards such as ditches, underground
lines, trees, cliffs and overhead wires.
MAINTENANCE
1. Do not attempt repairs unless trained.
Refer to manuals and experienced repair
personnel for help.
2. Follow all operating, maintenance and
safety information in the manual.
3. Support the machine with blocks or safety
stands when changing tires or working beneath it.
Death or serious injury can result from the
machine falling off a jack and crushing you.
4. Place all controls in neutral, stop engine,
remove ignition key and wait for all moving parts
to stop before servicing, adjusting or repairing.
Death or serious injury can occur from
entanglement in moving parts.
5. Follow good shop
practices: Keep service
area clean and dry. Be sure
electrical outlets and tools are
properly grounded. Use
adequate light for the job at
hand.

Safety ROSCO - A LeeBoy Company
RB48 BROOM
2.6
14. When inflating tires, use a self attaching
inflation chuck with a remote shut-off and stand
clear of the tire. A tire can explode with great
force.
15. Do not operate the unit with loose wheels or
rims. Check wheel nuts periodically for tightness.
Refer to the Bolt Torque chart at the end of the
Maintenance Section of this manual.
16. Keep brakes and steering systems in good
operatingcondition.
HYDRAULICS
1. Make sure that all components in the
hydraulic system are kept in good condition and
are clean.
2. Replace any worn, cut, abraded, flattened
or crimped hoses and metal lines.
3. Do not attempt makeshift repairs using
tape, clamps or cements. The hydraulic system
operates under extremely high pressure. Such
repairs can fail, creating a hazardous condition.
4. Wear proper hand and eye protection when
searching for a high pressure leak. Use a piece of
wood or cardboard as a back
stop to isolate and identify leaks.
Do not use your hands.
Relieve pressure on the system
before doing any repairs or
disconnecting lines, hoses or
valves. Before reapplying pressure to a hydraulic
system, make sure all lines, fittings and couplers
are tight and in good repair.
5. Pressurized hydraulic fluid or oil has
sufficient force to penetrate the skin. Serious
infection or toxic reaction
can develop from hydraulic
fluid piercing the skin. If
injured by a concentrated
high pressure stream of
hydraulic fluid, seek medical
attention immediately.
SAFETY
6. Make sure all guards are in place and
properly secured when maintenance work is
completed. Serious injury can occur from being
caught in unguarded moving parts.
7. Never wear baggy or frayed clothing when
working around or on any of the drive system
components. Loose garments can become
entangled in moving parts, pulling you into the
machine, causing serious injury or death.
8. Before applying pressure to a hydraulic
system, be sure all lines, fittings and couplers are
tight and in good condition. Leaking fittings are a
fire hazard. Hydraulic fluid under pressure can
pierce the skin, causing serious injury or toxic
reaction.
9. Wear protective
glasses and other required
safety equipment when
servicing or repairing the
broom.
10. Keep hands, feet, hair and
clothing away from moving parts.
Death or serious injury can occur
from entanglement in moving parts.
11. Clear the area of bystanders when carrying
out any maintenance, repairs or adjustments.
12. Do not service the broom while it is in
motion or while the engine is running. If the engine
must be running to service a component, place
Forward/Reverse control in neutral, apply parking
brake, block wheels and use extreme caution.
13. Do not make repairs on pressurized
components, fluid, gas or machinery until the
pressure has been properly relieved. Use
extreme caution when removing radiator cap,
drain plug, grease fitting or pressure taps. Park
the broom and let it cool before opening a
pressurized compartment.

6. Do not hammer on rims with steel
hammers. Use rubber, lead, plastic or brass faced
mallets if necessary.
7. Put hardwood blocks under the jacks
regardless of how hard the ground is. Block
wheels on opposite side of the vehicle before you
place a jack in position. Always support the
vehicle with blocks or preferably jack stands in
case the jack slips.
8. Do not operate the machine with loose
wheels or rims. Check wheel nuts for proper
torque.
REFUELING
1. Handle fuel with care. It is highly flammable.
When refuelling, keep the hose nozzle or funnel in
contact with the metal of the tank to avoid an
electrical shock igniting the fuel. Maintain control
of the filler nozzle.
2. Clean up spilled fuel before restarting the
engine. A spark could ignite the spillage.
3. Do not smoke while refueling
the machine. Do not refuel the
machine near open flame or sparks.
Do not refuel while the engine is
running. Do not use fuel for
cleaning purposes. Death or
serious injury can occur from explosion or fire.
4. Fill fuel tank outdoors to reduce the chance
of fumes accumulating and causing a fire or
explosion. Keep the hose nozzle or
funnel inside the tank while filling to
avoid spilling fuel. Spilled fuel is a fire
hazzard.
5. Prevent fires by keeping
machine clean of accumulated trash,
grease and debris.
6. Do not fill tank to capacity. Allow room for
expansion. Expansion and spillage create a fire
hazard.

SAFETY
7. Tighten the fuel tank cap securely. If cap is
lost, replace it only with the original manufacturer's
approved cap. A non-approved cap without proper
venting may result in pressurization of the tank.
8. Use the correct fuel grade for the operating
season. Refer to the Hydraulic Fluid chart in the
Maintenance section of this manual.
BATTERY
1. Keep all sparks and flames away from
batteries. Fumes from the battery's
electrolyte solution is extremely
explosive. Acid propelled by an
explosion can cause blindness if it
comes in contact with eyes.
2. Wear safety glasses when working near
batteries. If you come in contact with battery
electrolyte solution wash it off immediately.
3. Do not tip batteries more than 45 degrees to
avoid spilling electrolyte solution and causing a
chemical burn.
4. To avoid injury from spark or short circuit,
disconnect battery ground cable before
servicing any part of the electrical system. Failure
to do so can result in electrical shock or burn.
5. Use jumper cables only in recommended
manner. Improper use can result in battery
explosion or unexpected broom motion. Refer to
the Engine and Battery pages of the Maintenance
section of this manual.
SAFETY DECALS
1. Keep safety decals and signs clean and
legible at all times.
2. Become familiar with the content and
position of each safety decal. Refer to the Safety
Decal section in this manual for position and part
number.
3. Replace safety decals and signs that are
missing or have become illegible.
4. When replacing parts, be sure to check that
any safety decals that were on the original part
are also on the new part.
5. Obtain safety decals or signs from your
Authorized ROSCO Dealer/Distributor.
DECAL INSTALLATION
1. Be sure that the installation area is clean
and dry. Use hot soapy water and dry the area
thoroughly before installing decals.
2. Decide on the exact position by taking
measurements and test fitting before you remove
the backing paper.
3. For decals with no top protection paper,
decide on the decal location and remove the
smallest portion of the split backing paper.
4. Align the decal over the specified area and
carefully press the small portion with the exposed
adhesive backing into place.
5. Slowly peel back the remaining paper and
carefully smooth the remaining portion of the decal
in place.
6. Small air pockets can be pierced with a pin
and smoothed out using the piece of decal
backing paper.
7. If the decal has a protective top paper, use
hot soapy water on the surface to which the decal
is being applied. Leave wet. After deciding on the
location, remove the backing paper and soak the
decal in clean soapy water before application.
This will help prevent air bubbles in the finished
decal.
8. Smooth the decal into place with a sponge
and check for air bubbles. Small air pockets may
be pierced with a pin and smoothed out. When the
decal is completely smoothed out, carefully
remove the top paper.
