Safety Rules & Information
GENERAL OPERATION
• Read, understand, and follow all instructions in the
manual and on the unit before starting.
• Only allow responsible adults, who are familiar with
the instructions, to operate the unit (local regulations
can restrict operator age).
• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown.
• Be sure the area is clear of other people. Stop unit if
anyone enters the area.
• Always look down and behind before and while trav-
elling in reverse.
• Be aware of the discharge direction and do not point
it at anyone. Do not point the discharge at glass
enclosures, automobiles, or windows.
• Disengage all clutches (release drive and broom con-
trol levers) before starting the engine.
• Never leave a running unit unattended. Always disen-
gage the broom and traction controls and stop
engine.
• Operate only in daylight or good artificial light.
• Do not operate the unit while under the influence of
alcohol or drugs.
• Watch for traffic when operating near or crossing
roadways.
• Use extra care when loading or unloading the unit
into a trailer or truck.
• Keep in mind the operator is responsible for acci-
dents occurring to other people or property.
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control
of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.
The triangle in text signifies important cautions or warnings which must be followed.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip-
over accidents, which can result in severe injury or death.
All slopes require extra caution. If you cannot back up the
slope or if you feel uneasy on it, do not operate on it.
Do
• See your authorized dealer for recommendations
counterweights to improve stability.
• Travel up and down slopes, not across.
• Remove obstacles such as large rocks, tree limbs,
etc.
• Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Snow can hide obstacles.
• Use slow speed. Tires may lose traction on slopes.
Choose a low gear so that you will not have to stop or
shift while on the slope.
• Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
• Always keep unit in gear especially when traveling
downhill.
Do Not
• Do not start or stop on a slope. If tires lose traction,
disengage the broom and proceed slowly straight
down the slope.
• Do not turn on slopes unless necessary, and then,
turn slowly and gradually downhill, if possible.
• Do not operate near drop-offs, ditches, or embank-
ments. The unit could suddenly turn over if a wheel is
over the edge of a cliff or ditch, or if an edge caves in.
• Do not operate power broom on roof tops.
• Do not operate on wet surfaces. Reduced traction
could cause sliding.
• Do not shift to neutral and coast down hills.
WARNING
Never operate on slopes greater than 17.6 percent (10°) which
is a rise of 3-1/2 feet (106 cm) vertically in 20 feet (607 cm)
horizontally.
When operating on slopes use additional wheel weights or
counterweights. See your dealer to determine which weights
are available and appropriate for your unit.
Select slow ground speed before driving onto slope. Travel UP
and DOWN the slope, never across the face, use caution when
changing directions and DO NOT START OR STOP ON
SLOPE.
• Data indicates that operators, age 60 years and
above, are involved in a large percentage of power
equipment-related injuries. These operators should
evaluate their ability to operate the unit safely enough
to protect themselves and others from injury.
• All operators should seek and obtain professional
and practical instruction.
• Always wear substantial footwear and appropriate
clothing. Wear footwear that improves traction on
slippery slopes. DO NOT wear long scarves or loose
clothing that could become entangled in moving
parts.
• Before using, always visually check that all hardware
is present, in-tact, and secure. Replace worn or
damaged parts.
• Never operate the machine with defective guards, or
without safety protective devises in place.
• Stop engine before: refuelling, removing the broom
assembly, or making adjustments.
• Follow the manufacturer’s recommendation for wheel
weights or counterweights.
• Adjust support roller height to set proper ground con-
tact pattern.
• Do not touch power broom parts which may be hot
from operation. Allow such parts to cool before
attempting to service the unit.

CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
unit and the operating activity. Never assume that children
will remain where you last saw them.
• Keep children out of the area and under the watchful
care of another responsible adult.
• Be alert and turn unit off if children enter the area.
• Before and during reverse operation, look behind and
down for small children.
• Never allow children to operate the unit.
• Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
EMISSIONS
• Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
• Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
SERVICE AND MAINTENANCE
• Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel with the
engine running. Allow engine to cool before
refueling. Do not smoke.
c) Never refuel the unit indoors.
• If fuel is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until fuel vapors
have dissipated.
• Replace all fuel tank caps and fuel container caps
securely.
• Never fill containers inside a vehicle or on a truck bed
with a plastic bed liner. Always place containers on
the ground away from your vehicle before filling.
• Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possi-
ble, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dis-
penser nozzle.
• Keep nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is com-
plete. Do not use a nozzle lock-open device.
• If fuel is spilled on clothing, change clothing immedi-
ately.
• Maintain or replace safety and instruction labels as
necessary.
• Never run a unit in an enclosed area.
• Keep nuts and bolts tight and keep equipment in
good condition.
• Never tamper with safety devices. Check their proper
operation regularly and make necessary repairs if
they are not functioning properly.
• Keep unit free of debris build-up. Clean up oil or fuel
spillage.
• Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
• Never make adjustments or repairs with the engine
running unless specified otherwise in the engine
manufacturer’s manual.
• Components are subject to wear, damage, and dete-
rioration. Frequently check components and replace
with manufacturer’s recommended parts, when nec-
essary.
• Check control operation frequently. Adjust and ser-
vice as required.
• Use only factory authorized replacement parts when
making repairs.
• Always comply with factory specifications on all set-
tings and adjustments.
• Only authorized service locations should be utilized
for major service and repair requirements.
• Never attempt to make major repairs on this unit
unless you have been properly trained. Improper ser-
vice procedures can result in hazardous operation,
equipment damage and voiding of manufacturer’s
warranty.
• Do not change engine governor settings or over-
speed the engine. Operating the engine at excessive
speed can increase the hazard of personal injury.
• Disengage broom and traction, stop the engine, and
disconnect the spark plug wire(s) before: performing
service work or if the unit vibrates abnormally. After
striking an object, inspect the machine for damage
and make repairs before restarting and operating the

Storage
TEMPORARY STORAGE
(30 DAYS OR LESS)
Remember, the fuel tank will still contain some gasoline, so
never store the unit indoors or in any other area where fuel
vapor could travel to any ignition source. Fuel vapor is also
toxic if inhaled, so never store the unit in any structure used
for human or animal habitation.
Here is a checklist of things to do when storing your unit
temporarily or in between uses:
• Keep in an area away from where children may come
into contact with it. If there’s any chance of unauthorized
use, remove the spark plug wire.
• If the unit can’t be stored on a reasonable level surface,
chock the wheels.
• Clean all debris and snow from the unit.
NOTE: If storing your unit between winter snow removal
jobs in a cold area, we suggest that you fill the fuel tank at
the completion of each job to prevent water condensation in
the fuel tank. Wait for engine to cool before filling tank.
LONG TERM STORAGE
(LONGER THAN 30 DAYS)
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety Rules
section, then perform the following steps:
1. Drain crankcase oil and refill with a grade of oil that will
be required when unit is used again.
2. Coat all bare metal surfaces with paint or light coat of oil
to prevent rusting.
3. Clean external surfaces and engine.
4. Prepare engine for storage. See engine owner’s
manual.
5. Clean any dirt from the engine housing.
6. Cover air intake and exhaust outlet tightly with plastic or
other waterproof material to keep out moisture, dirt and
insects.
7. Completely grease and oil as outlined in the Normal
Care section.
8. Drain fuel system completely or add a gasoline stabilizer
to the fuel system. If you have chosen to use a fuel sta-
bilizer and have not drained the fuel system, follow all
safety instructions and storage precautions in this man-
ual to prevent the possibility of fire from the ignition of
gasoline fumes. Remember, gasoline fumes can travel
to distant sources of ignition and ignite, causing risk of
explosion and fire.
NOTE: Gasoline, if permitted to stand unused for extended
periods (30 days or more), may develop gummy deposits
which can adversely affect the engine carburetor and cause
engine malfunction. To avoid this condition, add a gasoline
stabilizer to the fuel tank or drain all fuel from the system
before placing unit in storage.
STARTING AFTER
LONG TERM STORAGE
Before starting the unit after it has been stored for a long
period of time, perform the following steps.
1. Remove any blocks from under the unit.
2. Unplug the exhaust outlet and air cleaner.
3. Fill the fuel tank with fresh gasoline. See engine
manual for recommendations.
4. See engine owner’s manual and follow all instructions
for preparing engine after storage.
5. Check crankcase oil level and add proper oil if
necessary.
6. Inflate tires to proper pressure.
7. Start the engine and let it run slowly. DO NOT run at
high speed immediately after starting. Be sure to run
engine only outdoors or in well ventilated area.
WARNING
Never store the unit, with gasoline in engine or
fuel tank, in a heated shelter or in enclosed,
poorly ventilated enclosures. Gasoline fumes may
reach an open flame, spark or pilot light (such as

Regular Maintenance
CHECKING TIRE PRESSURE
The air pressure in each tire (Figure 8) should be 20 psi
(136 kPa) and should be equal for both tires for best per-
formance. Be sure to keep caps on valves to prevent
entry of debris into the valve stem when tires are filled.

Regular Maintenance
LUBRICATION
1. Apply medium weight (10W) oil to points shown (See
Figures 9-12).
2. Remove wheels and grease axles once each year
(See Figure 11).
3. Apply 5W-50 synthetic motor oil to the friction disk
drive hex shaft.
4. Grease broom drive universal joint (See Figure 12).
NOTE: Access is best gained from underneath
machine.
5. Grease broom pivot pin (See FIgure 12).
Generally, all moving metal parts should be oiled where
contact is made with other parts. Keep oil and grease off
belts, pulley grooves, drive disc, and friction disc.
LUBRICATION NOTES:
Grease locations indicated by grease gun sym-
bol. Use grease fittings when present.
Disassemble parts to apply grease to moving
parts when grease fittings are not installed.
Oil locations indicated by oil can symbol. Do
not allow oil to drip onto traction drive or friction
disc.
IMPORTANT NOTE
It is very important that grease fittings on the
broom shaft are lubricated regularly. If broom
rusts to shaft, damage to worm gear may occur
if shear pins do not break.
To prevent wheels rusting to axles, it is also
necessary to remove the wheels and grease the
axles regularly.
