SAFETY PRECAUTIONS
Careful operation is your best insurance against an accident. Read this section carefully before operating the tractor
and the rotary broom. All operators, no matter how experienced they may be, should read this and other manuals
related to the tractor and rotary broom before operating. It is the owner's legal obligation to instruct all operators in how
to safely operate the rotary broom.
TRAINING
This symbol, "Safety Alert Symbol", is used
throughout this manual and on the attachment’s
safety labels to warn of the possibility of serious
injury. Please take special care in reading and
understanding the safety precautions before
operating the tractor or the rotary broom.
1. Read this owner's manual carefully. Be thoroughly
familiar with the controls and proper use of the
rotary broom. Know how to stop the unit and
disengage the controls quickly.
2. Never allow children to operate the tractor nor the
rotary broom. Never allow adults to operate the
tractor nor the rotary broom without proper
instructions.
3. No one should operate the tractor nor the rotary
broom while intoxicated or while taking medication
that impairs the senses or reactions.
4. Keep the area of operation clear of all persons,
particularly small children and pets.
PREPARATION
1. Thoroughly inspect the area where the rotary broom
is to be used and remove door mats, all foreign
objects and the like.
2. Disengage all clutches and shift into neutral before
starting engine.
3. Do not operate the rotary broom without wearing
adequate outer garments. Avoid loose fitting
clothing that can get caught in moving parts. Wear
footwear that will improve footing on slippery
surfaces.
4. Handle fuel with care, it is highly flammable.
a) Use approved fuel container.
b) Never add fuel to a running engine or hot
engine.
c) Fill fuel tank outdoors with extreme care. Never
fill fuel tank indoors.
d) Never fill containers inside a vehicle, or on a
truck or a trailer bed with a plastic liner. Always
place containers on the ground, away from your
vehicle, before filling.
7
OPERATION
1. Do not put hands or feet near or under rotating
parts.
2. Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay alert
for hidden hazards or traffic. Do not carry
passengers.
3. After striking a foreign object, stop the engine
(motor), disconnect the wire from the spark plug(s)
and keep wire away to prevent accidental starting.
Thoroughly inspect the rotary broom for any
damage and repair damage before using.
4. If the unit should start to vibrate abnormally, stop
the engine (motor) and check immediately for the
cause. Vibration is generally a warning of trouble.
e) When practical, remove gas-powered equipment
from the truck or trailer and refuel it on the
ground. If this is not possible, then refuel such
equipment on a trailer with a portable container,
rather than from a gasoline dispenser nozzle.
f) Keep the nozzle in contact with the rim of the
fuel tank or container opening at all times, until
refuelling is complete. Do not use a nozzle lock-
open device.
g) Replace fuel cap securely and wipe up spilled
fuel.
h) If fuel is spilled on clothing, change clothing
immediately.
4. Never attempt to make any adjustments while the

PRESSURE ON THE BRUSH ADJUSTMENT
By turning the adjustment screw (item 3) counter
clockwise, the gauge (item 2) moves higher and the
pressure of the brush on the ground increases. By
turning the adjusting screw clockwise, the gauge
moves lower on the gear box frame and the pressure
of the brush on the ground decreases.
IMPORTANT: Maintain the gauge (item 2) even with
the top of the gear box frame (item 1) or lower for
general hard surface sweeping. Adjust frequently to
compensate for brush wear. Remember to sweep
with the tips of the bristles like a broom and not with
the sides of the bristles like a mop. Too much
pressure can decrease the brush life up to 95%.
7
WARNING
7
TO PREVENT INJURIES AND FOR MORE
TRACTION WHEN USING AN ATTACHMENT:
-Rear counterweights of 100 lbs. minimum are
required to counter-balance attachment’s
weight.
-Tractor manufacturer approved tire chains are
required.
-Do not operate on slopes greater than 10°.
When dismounting an attachment remove rear
counterweights.
GENERAL SWEEPING
Minimize dust by reducing brush speed and by
sweeping after rain or on a day with high moisture.
SNOW SWEEPING
Adjust the gauge (item 3) to be even with the top of
gear box frame (item 2). The broom works well for
light snow removal.
Sweep with the wind blowing in the direction of broom
discharge.
WARNING: Foreign objects in the snow may be
thrown faster than the snow itself.
Frequently clean the snow and ice accumulation from
the top and bottom of the broom hood.
LAWN DETHATCHING AND LEAF RAKING:
Lower the broom on a hard surface and lift the brush
1" from the ground by turning the adjusting screw
clockwise. This adjustment is normally satisfactory
but you may raise or lower depending upon grass
height.
Low brush speed and ground speed is best for lawn
dethatching and leaf raking.
Adjust the pressure on the brush
Never sweep with the sides of
bristles! Sweep with the tips!
Do not mop!
Too much pressure=
Shortens brush life! Road surface
Flick action
