TRAINING
1. Read, understand, and follow all instructions on the
machine and in the manual(s) before attempting to
assemble and operate. Keep this manual in a safe place
for future and regular reference and for ordering
replacement parts.
2. Be familiar with all controls and their proper operation.
Know how to stop the machine and disengage them
quickly.
3. Never allow children under 14 years old to operate this
machine. Children 14 years old and over should read and
understand the operation instructionsand safety rules in
this manual and should be trained and supervised by a
parent.
4. Never allow adults to operate this machine without proper
instruction.
5. Thrown objects can cause serious personal injury. Plan
your snow throwing pattern to avoid discharge of material
toward roads, bystanders and the like.
6. Keep bystanders, helpers, pets and children at least 75
feet from the machine while it is in operation. Stop
machine if anyone enters the area.
7. Exercise caution while operating tractor with this
attachment, especially when traveling in reverse.
PREPARATION
1. Thoroughly inspect the area where the equipment is to be
used. Remove all door mats, newspapers, sleds, boards,
wires and other foreign objects which could be thrown by
the augedimpeller.
2. Always wear safety glasses or eye shields during
operation and while performing an adjustment or repair to
protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
3. Do not operate without wearing adequate winter outer
garments. Do not wear jewelry, long scarves or other
loose clothing which could become entangled in moving
parts. Wear footwear which will improve footing on
slippery surfaces.
4. Adjust collector housing height to clear gravel or crushed
rock surfaces.
5. Disengage all clutches and shift into neutral before
starting the engine.
Never attempt to make any adjustments while engine is
running, except where specifically recommended in the
operator's manual(s).
7.
Let tractor engine and attachment adjust to outdoor
temperature before starting to clear snow.
8.
To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Serious
personal injury can occur when gasoline is spilled on
yourself or your clothes which can ignite. Wash your skin
and change clothes immediately.
a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
c. Never fuel machine indoors.
d. Never remove gas cap or add fuel while the
engine is hot or running.
e. Allow engine to cool at least two minutes before
refueling.
f. Never over fill fuel tank. Fill tank to no more than Y2
inch below bottom of filler neck to provide space
for fuel expansion.
g. Replace gasoline cap and tighten securely.
h. If gasoline is spilled, wipe it off the engine and
equipment. Move machine to another area. Wait 5
minutes before starting the engine.
i. Never store the machine or fuel container inside
where there is an open flame, spark or pilot light
(e.g. furnace, water heater, space heater, clothes
dryer etc.).
j. Allow machine to cool at least 5 minutes before
storing.
OPERATION
1. Do not put hands or feet near rotating parts, in the auger/
impeller housing or discharge chute. Contact with the
rotating parts can amputate hands and feet.
2. Never operate with a missing or damaged discharge
chute. Keep all safety devices in place and working.
3. Never run an engine indoorsor in a poorly ventilated
area. Engine exhaust contains carbon monoxide, an
odorless and deadly gas.
4. Do not operate machine while under the influence of
alcohol or drugs.
5. Muffler and engine become hot and can cause a burn. Do
not touch.

However, ifyou're mounting model 823 snow thrower
attachment to a tractor equipped with a 54-inch deck,
proceed as follows.:
• Remove the flange nut, washer and shoulder
spacer which secures the double-idler bracket to
the undercarriage. See Figure 2.
