 Do not turn on slopes or travel across
slopes; always go down to a flat place to
perform these operations.
 When traveling downhill, never shift gears
or shift to neutral. Always shift to a low gear
before starting to travel downhill.
 When traveling downhill, use the engines
braking force and travel slowly. If necessary,
use the brake pedal to reduce the speed.
 At high speeds, do not travel on grass,
fallen leaves, or wet steel plates. Even slight
slopes may cause the machine to slip to the
side, so travel at low speed and make sure that
the machine is always traveling directly up or
down the slope.
 If the engine shuts off when traveling
downhill, using the brake pedal and fully the
apply the brakes. Lower the bucket to the
ground, and then apply the parking brake to
hold the machine in position.
 When traveling up or down hills with a
loaded bucket, always travel with the bucket
facing uphill (travel forward when going uphill
and in reverse when going downhill). When
traveling on a slope with a loaded bucket, if the
machine travels with the bucket facing downhill,
there is danger that the machine may tip over.
High-Voltage Cables
 Do not let the machine touch electric
cables; even getting close to high-voltage
cables can cause electric shock. Always
maintain the safe distance given below
between the machine and the electric cable.

 To prevent accidents, always do as
follows:
1. On the jobsite where there is danger
that the machine may touch the electric
cables, consult the electric company
before starting operations to confirm that
the appropriate precautions are taken and
that the work abides to regulations.
2. Wear rubber shoes and gloves. Lay a
rubber sheet on top of the operator’s seat,
and be careful not to touch the chassis
with any exposed part of your body.
3. Use a signalman to give warning if the
machine approaches the electric cables.
4. If the work tools should touch the
electric cable, the operator should not
leave the operator’s compartment.
5. When carrying out operations near
high voltage cable, do not let anyone come
close to the machine.
6. Check with the electricity company
about the voltage of the cables before
starting operations.
Driving Precaution
 Be careful not to get too close to the edge
of cliffs. When marking embankments, landfills,
or when dropping soil over a cliff, dump one
pile and then use the next pile of soil to push
the first pile.
 The load suddenly becomes lighter when
the soil is pushed over a cliff or when the
machine reaches the top of a slope. When this
happens, there is danger that the travel speed
will suddenly increase, so be sure to reduce
the speed.
 When the bucket is fully loaded, never
start, turn, or stop the machine suddenly.
 When handling unstable loads, such as
