2. BEFORE STARTING THE LAWN MOWER
2.1. Set up an operation plan with sufficient time al-
lowance. A tight plan may result in unexpected
accidents. Especially when operating the lawn
mower under extremely hot, cold, or humid cir-
cumstances, set up an operation schedule or
method which will ensure operational safety.
2.2. Mow only in daylight or good artificial light. Mow-
ing in the dark may cause unexpected accidents.
2.3. Thoroughly inspect the mowig area and remove
all objects from the mowing area that the lawn
mower can throw, such as stones, toys, sticks,
and wires, which may lead to serious accidents.
2.4. Ensure that there are no people or pets in the
area where you will mow. Keep children out of the
mowing area and under the watchful care of a re-
sponsible adult.
2.5. Do not operate the lawn mower unless the op-
erator’s presence controls, safety switches, and
guards are attached and functioning properly.
2.6. Start the engine from the operating or designated
starting position.
2.7. Before starting the engine, make sure that every-
thing is safe around the front mower and put the
traction drive in neutral, set parking brake, and
disengage the cutting unit(s). Otherwise, unex-
pected accidents may occur.
2.8. Start the engine with the starter switch only.
Never attempt to start the engine by shorting the
terminals, or the lawn mower may move abruptly,
and result in unexpected accidents.
2.9. Do not run the engine in an enclosed area where
dangerous carbon monoxide fumes can collect.
Sufficient ventilation should be provided when
starting the engine in an enclosed area.
2.10. Make sure if safety around the lawn mower and
move slowly when starting. Abrupt starting may
cause unexpected accidents.
2.11. Become familiar with the operation, particularly,

by the manufacturer and install and operate them
as directed.

2.13. Be sure to operate the lawn mower equipped with
a standard mower deck and collector. Never mow
grass without the collector, or the lawn mower
scatters grass, stone and other flying debris,
which is very dangerous, if you would like not to
collect the cut glass in a collector, equip an op-
tional discharge cover for collector.

2.14. When your lawn mower is equipped with an
implement other than a standard mower deck and
collector, never fail to ask your dealers about ma-
chine balance. Always follow their advice.
2.15. Keep in mind that the operator or user is respon-
sible for the accidents or hazards caused by the
lawn mower to other people or their property.
2.16. Inspect the front mower for wear or damage.
Replace any worn or damaged parts.
2.17. Especially before starting the mower, be sure to
perform advised preoperation inspections espe-
cially on the brakes and inspect visually to see
that the blade and blade tightening nuts are not
worn, damaged or loose. Replace worn or dam-
aged blade and nuts as an assembly to preserve
blade balance. Otherwise, poor braking or scat-
tered broken blades may result, which is very
dangerous.
