2.2. Thoroughly inspect the area where the lawn
mower is to be used and remove all stones,
sticks, wires, and other foreign objects.
Otherwise, they will be hit by the mower blades,
which may lead to serious accidents.
2.3. The lawn mower is equipped with various safety
systems. All safety shields, guards, and covers
should always be in position and functioning
properly.
2.4. 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.
2.5. Before starting the engine, make sure that
everything is safe around the lawn mower and all
control levers are in the neutral or off positions,
the parking brakes applied, and the PTO lever
in the OFF position. Otherwise, unexpected
accidents may occur.
2.6. 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.
2.7. Never start the engine in a closed place. Exhaust
fumes contain poisonous carbon monoxide, so
sufficient ventilation should be provided when
starting the engine indoors.
2.8. Make sure if safety around the lawn mower and
move slowly when starting. Abrupt starting may
cause unexpected accidents.
2.9. Become familiar with the operation, particularly,
the stopping of the lawn mower. You should be
skilful enough to be able to stop the lawn mower
at will.
2.10. When your lawn mower is equipped with an
inplement other than a standard mower deck
and collector, never fail to ask your dealers about
machine balance. Always follow their advice.
2.11. Keep in mind that the operator or user is
responsible for the accidents or hazards caused
by the lawn mower to other people or their
property.
2.12. Especially before starting the mower, be sure
to perform advised preoperation inspections
especially on the brakes and inspect visually
to see that the blade and blade tightening nuts
are not worn, damaged or loose. Replace worn
or damaged blade and nuts as an assembly to
preserve blade balance. Otherwise, poor braking
or scattered broken blades may result, which is
very dangerous.
2.13. Machine weight balance is a very important
factor for safe operation. When your machine
is equipped with an implement other than a
standard mower deck and collector, never fail to
ask your dealers about machine balance. Always
follow their advice.

accessories and etc. away so as not to be caught
in the moving parts of the lawn mower
3.12. Always pay attention in lawn of the lawn mower
to avoid obstacles such as corner stones, stubs,
sprinkler heads, etc. When there is an obstacle
that cannot be removed, provide a marker flag
as a warning to keep away from it when mowing.
When approaching the obstacle, slow down the
lawn mower sufficiently to avoid it.
3.13. Never rest a foot on the brake pedal. If so, the
brakes wear rapidly, which may lead to serious
accidents.
3.14. Adjust the cutting height with the gauge wheels
in accordance with the condition of the ground
surface at the working site. Mowing on rough
ground with low cutting height may cause

implement or a trailer. It is not designed to draw a
load.
3.23. Never attempt sudden starting and stopping,
otherwise it causes not only damaged lawn but
deterioration of durability of lawn mower.
4. OPERATION ON A SLOPE
We cannot recommend this lawn mower be operated on
a slope, but advise you to use a lawn mower designed
for slope operation. On a slope, various elements of
operation such as slope angles, ground conditions, way
of operation, grass conditions, etc. may lead to slipping,
or over-turning of the lawn mower, which may result in
bodily injury.
If the lawn mower has to be used on a slope, remember
there is on such thing as a "safe" slope. Never use it on
a slope of more than "12°", and be sure to abide by the

10. ELECTRICAL SYSTEM
10.1. Before servicing the electrical system, be sure
to stop the engine, lower the mower deck on the
ground, draw the starter key, shift the PTO lever
to the OFF position, and apply parking brakes.
10.2. Before inspecting the connections of the electrical
system, be sure to disconnect the negative
terminal of the battery to avoid short circuits and
electric shocks.
(1) Negative cord
10.3. Loose connections, terminals, and damaged
wiring should be repaired as soon as possible.
They will not only deteriorate the performance of
electric parts but also may cause short circuits,
leading to fires.
10.4. The surroundings of the wiring and the battery
should be kept clean, or accumulated grass or
chaff may catch fire.
10.5. Never smoke nor allow any open flames nearby
or sparks, which may be caused by short
circuits during servicing the battery. The battery
generates explosive gases(hydrogen and oxygen)
during charging, so the battery should becharged
in a place well ventilated to let such explosive
gases diffuse smoothly. Otherwise settled gases
may catch fire.

10.6. Battery electrolyte is diluted sulphuric acid, so it
is corrosive and naturally poisonous. Never allow
acid to contact skin or clothing, or it may cause
burns. Always wear a face shield to avoid acid
getting in eyes. If acid contacts skin or clothing,
wash off immediately with clean water. If acid
contacts eyes, flush immediately with clean water
and get medical attention.
10.7. Before servicing and mounting or dismounting
the battery, stop the engine, draw the starter key,
and apply the parking brakes. Otherwise, electric
parts may be damaged.
10.8. When disconnecting the battery, disconnect
the negative(-) cable first, while connect the
positive(+) cable first when connecting the
battery. Wrong order of disconnecting or
connecting the battery will cause sparks, which is
very dangerous.
(1) Negative cord (2) Positive cord
10.9. When using booster cables, observe the following
instructions to avoid accidents:
･ Remove the filler caps of battery cells ahead of
time to lessen explosive power of gases if they
should catch fire.
･ Before connecting booster cables, be sure to stop
the engine.
･ Use booster cables of sufficient capacity, or they
may be heated or burnt out.
11. TYRES AND WHEELS
11.1. Be sure to keep tyre pressures at the levels
specified in this manual. Excessively high tyre
pressure may result in explosion, which may lead
to physical accidents.
11.2. If a cut is found in a tyre and the cut reaches the
cords, do not use it. Such a tyre may explode.
11.3. Before replacing or repairing tyres, tubes, or
rims, consult your dealers ahead of time. Such
operation should be performed by trained
mechanics.
12. BEFORE STORING THE LAWN MOWER
12.1. After opeation, be sure to close the fuel cock
to prevent fuel from spilling, as spilled fuel may
catch fire.
12.2. Never allow grass or leaves to acoumulate
around heated parts such as the engine and the
muffler, or this may cause a fire.
12.3. Be sure to remove the ignition key to prevent
unexpected accidents caused by engine starting
by untrained persons or children.
12.4. When storing the lawn mower with the mower
deck attached, be sure to lower the mower deck
on the ground. Otherwise manipulation of the lift
lever by untrained person or children may cause
unexpected accidents.
12.5. Store the lawn mower in a place provided with

12
sufficient illumination. Inspection and moving
of the lawn mower in a dark place may lead to
unexpected accidents.
12.6. When the lawn mower is to be stored in a closed
place like a garage or a barn, provide sufficient
ventilation for exhaust gases. Exhaust fumes can
be lethal.
12.7. To avoid fire hazard, keep the engine, muffler,
battery, and fuel storage area free of grass,
leaves, or excessive grease.
12.8. Never cover a hot lawn mower just after operation
with a tarpaulin or the like, or the heated engine
and related parts may cause a fire.
13. LONG TERM STORAGE
13.1. Before storing the lawn mower for long period
of time, disconnect the battery cables to prevent
them, in case they are gnawn by rats, from
causing a short circuit, which may lead to a fire.
When disconnecting the battery, disconnect
the negative(-) cable first, while connecting
the positive(+) cable first when connecting
the battery. Wrong order of disconnecting on
connecting the battery will cause sparks, which is
very dangerous.
