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.
