SAFETY
• If you drive the machine at high speed continuously for a long time, the tires will overheat and the internal
pressure will become abnormally high. This may cause the tires to burst. If a tire bursts, it produces a large
destructive force, and this may cause serious injury or death.
• Directional lever or directional selector switch (if equipped) must not be set to NEUTRAL position (N) while
traveling or traveling downhill. Set the direction of directional lever or directional selector switch (if equip-
ped) in the traveling direction of the machine.
• It is dangerous that the engine brake is disabled and the steering wheel becomes heavier.
• The transmission and other parts of the power train may be damaged, and it may cause serious per-
sonal injury or death.
PRECAUTIONS WHEN TRAVELING ON SLOPES
To prevent the machine from tipping over or slipping to the side, always observe the following.
• Keep the work equipment at height (A) of approximately 20
to 30 cm above the ground. In case of emergency, lower
the work equipment to the ground immediately to help
stopping the machine.
• Always drive the machine straight up or down a slope.
Driving the machine at an angle or across the slope is ex-
tremely dangerous.
• Do not turn on slopes or drive across slopes. Always go
down to a flat place to change the position of the machine,
then drive it on to the slope again.
• Drive the machine at low speed on the grass or fallen leaves. Even with slight slopes, there is a hazard that
the machine may slip.
• If the engine should stop on a slope, depress the brake pedal immediately, lower the bucket and apply the
parking brake to stop the machine.
• When traveling downhill, never shift gear or place the transmission at neutral.
Engine brake does not work and dangerous. Always set the transmission to a low gear before starting to
travel downhill.
• When driving the machine downhill, drive it slowly at low speed. Depress the brake pedal or use the engine
brake as necessary.
