In this manual, "attachment" means accessories that you install on the tractor, such as, snowblower, rotary
broom, blade, rotary tiller, cab, subframe, etc...
SAFETY PRECAUTIONS
TRAINING
This symbol, "Safety Alert Symbol", is used
throughout this manual and on the attachment
safety labels to warn of the possibility of
personal injury. Please take special care in
reading and understanding the safety
precautions before operating the attachment
or the tractor.
1. Read this Owner's Manual carefully. Be thoroughly
familiar with the controls and proper use of the
attachment. Know how to stop the unit and
disengage the controls quickly.
2. Never allow children to operate attachment. Never
allow adults to operate attachment without proper
instructions.
3. No one should operate the unit 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. Disengage all clutches and shift into neutral before
starting engine.
2. 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) Replace fuel cap securely and wipe up spilled
fuel.
3. Never attempt to make any adjustments while
engine is running (except where specifically
recommended by manufacturer).
4. Always wear safety glasses or eye shields during
operation or while performing an adjustment or
repairs to protect eyes from foreign objects that
may be thrown from the machine.
OPERATION
1. Do not run engine indoors except when starting
engine and transporting attachment, in or out of
building. Do not operate or let motor run in a
storage area without ventilation because gas
contains carbon monoxide which is odourless,
colourless and can cause death.
2. Do not carry passengers on attachment or tractor.
3. Take all possible precautions when leaving the
machine unattended. Lower the attachment, shift
into neutral, set the parking brake, stop the engine
and remove the key. Wait for all moving parts to
stop.
4. You must use manufacturer approved rear
counterweights, minimum 100 lbs., for better
traction and safety at all times when you have an
attachment installed in front.
5. Never operate the attachment without good visibility
or light.

Careful operation is your best insurance against an accident. Read this section carefully before operating the tractor
and attachment. All operators, no matter how experienced they may be, should read this and other manuals related to
the tractor and attachments before operating. It is the owner's legal obligation to instruct all operators in safe operation.

SAFETY PRECAUTIONS
MAINTENANCE AND STORAGE
1. Check shear bolts, mounting bolts, etc..., at frequent
intervals for proper tightness to be sure attachment is
in safe working condition.
2. Never store the machine with fuel in the tank inside a
building where ignition sources are present, such as
hot water tanks, space heaters, clothes dryers and
the like. Allow engine to cool before storing in any
enclosure.
3. Maintain or replace safety and instructions labels, as
necessary.
