3.27. Never attempt to use the front mower to draw an
implement or a trailer. It is not designed to draw a
load.
3.28. Stay alert and stop the front mower if people or
pets enter the area.
3.29. Do not carry passengers
3.30. Never carry children, even when the cutting
means are not moving. Children may fall off
the front mower and become seriously injured
or prevent you from operating the front mower
safely. Children who have been given rides in the
past may suddenly appear in the mowing area for
another ride and be run over or backed over by
the front mower.
3.31. If you use the lawn mower for long time, make
sure to take rest every 2 or 3 hours.
3.32. When you hear thunder, stop the lawn mower
and move indoors immediately. If you cannot
move indoors, get to low place. Otherwise, you
can be struck by lightning.
3.33. Before stopping the engine, be sure to lower the
mower deck onto the ground, apply the parking
brakes and turn the PTO switch to the OFF
position.
3.34. Before leaving the operating position of the front
mower for any reason, always do the following:
- Stop the front mower on level ground.
- Stop the cutting unit(s), disengage PTO, and
lower the attachment(s).
- Disengage the drive(s).
- Apply the parking brake. In order to maximize the
performance of the parking brake, depress the
brake pedal, and then apply the parking brake.
- Stop the engine and wait for all moving parts to
stop.

13. LONG TERM STORAGE
13.1. Never store the mower with fuel in the tank inside
a building where fumes can reach an open flame
or spark
13.2. Lower the cutting unit(s) when you store the front
mower, unless you lock the cutting unit(s) into
position.
13.3 Allow the engine to cool before storing the front
mower in any enclosure.
13.4. Before storing the front mower for a long period
of time, disconnect the battery cables to prevent
them, in case they are gnawed 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 or
connecting the battery will cause sparks, which is
very dangerous.

1.8. FUEL GAUGE
The gauge indicates fuel level in the fuel tank when the
starter switch is in the ON position.
When needle is the closer to “F”, the more fuel is in the
fuel tank. So not let the fuel gauge reach the empty
point, "E".
NOTE: The gauge can not indicate an accurate fuel
level when the front mower is on the slope. It
takes a little time to indicate an accurate level
after the front mower recovers its horizontal
position.

1.9. HOUR METER
The hourmeter counts operation hours of the front
mower and show them in 5-digit number. The least QUARTZ
significant figure shows one tenth hour of operation.

1.10. COOLANT TEMPERATURE WARNING SYSTEM HOURS
(HORN AND LAMP)
UNIDECK
IMPORTANT: When the engine coolant is over-heated,
the warning horn sounds for 2 seconds
and Engine coolant warning lamp illumi-
nates. Rotation of the radiator fan is re- FIG. 36
versed for a few second, and then PTO (8) Hour meter
is stopped automatically.
When the warning horn sounds,
decelerated the engine to idling, and wait
until the warning horn turns off.
When the warning horn turns off, stop
the engine and correct the trouble
(clogged grass or dust around engine,
radiator, etc.). Then re-start operation.
WARNING: When inspecting the radiator,
be sure that the engine cools down
sufficiently. Never release the radiator cap
while the coolant is hot, or boiling water will
gush out.

4. 4WD LEVER
With this lever, 2WD/4WD automatic change-over and
permanent 4WD is selectable.
4WD PERM: Shift(push) the lever to engage permanent
4WD mode.
4WD AUT: Shift(pull) the lever to engage AUTO 4WD
mode.
In AUTO 4WD mode, 2WD and 4WD is selected
automatically during operation on a level ground, so the
lever operation is not required.
FIG. 47
When operating on a slope, shift the changeover lever (1) 4WD Shift Lever
to the 4WD position without fail.
IMPORTANT: Be sure to shift the 4WD lever to the
"AUTO" position when operating on level
ground, as level ground operation with
the 4WD selected leads to a larger turn-
ing radius and may cause turf damage.
IMPORTANT: When shifting the 4WD lever, slow down
the travelling speed below 1 km/h and
make the machine go straight.
WARNING:When operating the front mower
on a slope, be sure the 4WD lever is locked
in the 4WD position from the reasons
mentioned below:
In the AUTO position the mechanism shifts to 2WD
automatically when the peripheral speed of the front
wheels exceeds that of the rear wheels, which means
loss of rear wheel driving power.
For example, when moving uphill if the front wheels
slip, the mechanism stays in 4WD. But moving downhill
if the front wheels slip and lose grip, and begin to slip
down the slope, it shifts to 2WD, that is, braking effect
of the HST unit is lost, which means loss of front mower
control.
From another point of view, when you try to turn the front
mower on a slope, rear wheel driving power is lost and
the front mower may slip down the slope, which is also
very dangerous.

12. WHEEL TIGHTENING BOLTS AND NUTS
Check the wheel tightening bolts and nuts for looseness
All bolts and nuts should be tightened to the specified
torque.
Specified tightening torque (Bolt):
Front wheel: 45.1 N・m 〜 57.9 N・m (460 kgf・cm 〜 590 kgf・cm)
Rear wheel: 127.2 N・m 〜 147.2 N・m (1298 kgf・cm 〜 1502 kgf・cm)
Tighten the bolts near the maximum level and tighten
again so that the groove and hole aligned together,
insert the cotter pin through the hole and groove, sprit
the edge of it.
13. BATTERY
DANGER:
・The battery generates very explosive
gases, so avoid smoking and keep sparks
and open flames away from the battery.
Charging the battery should be done in a
place well ventilated to disperse explosive
gasses as quickly as possible.
・Battery electrolyte is very corrosive and
will cause burns, so if it splashes on skin
or clothes, wash it off immediately. If acid
contacts eyes, flush immediately with
clean water and get medical attention.
・When using booster cables, take FIG. 72
sufficient safety measures. (1) Battery
■ INSPECTION OF BATTERY
The battery,1, is installed on the middle of the left hand
side of the front mower. Check to see if the electrolyte
level is between the upper and lower limits. When the 2
level is near to the lower limit or below, raise the level
with distilled water to the upper limit.
WARNING: Never attempt to keep on using
A
or charging the battery with a electrolyte 1
level lower than the limit, or the battery may
explode or its service life be shortened due
to deterioration inside the casing.
IMPORTANT: The electrolyte level should always be B
kept between the upper and lower limits. A
too high level will cause the electrolyte to
overflow and corrode other parts.

25. WASHING OF THE MACHINE
CAUTION: If you use compressed water, be sure to use in accordance with this operator’s manual
and safety label. In case of irregular use, it may cause personal injury and damage to the machine.
CAUTION: Set the spraying nozzle in ‘spread’ position and keep the distance away from the machine
more than 60 cm in order to avoid damage to the machine. Especially, be care not to hit the
compressed water to electrical parts and label.
Unsuitable washing may cause the following accidents;
1. Fire as a result of short circuit or the damage to the electrical parts.
2. Oil leakage as a result of the damage to the hydraulic hose.
3. Damage to the machine.
(1) Label peeling.
(2) Accident occurs by the damaged electrical parts, engine, radiator, and interior.
(3) Lubber parts (tire, seal) and resin parts are damaged.
(4) Paint peeling.
Keep the distance more
than 60 cm
