traveling. In both cases, pay special attention to the ground ahead of the
While traveling on a slope, lower the bucket to 20~30cm off the ground. While climbing
up a steep slope, extend the bucket working device to the front position. In event of an
emergency, lower the bucket onto the ground and stop the engine of machine.
When walking on slopes or ramps, drive slowly. Reduce engine speed when going
downhill. Do not reverse the machine down a slope.
Do not change direction on slopes or cross slopes. First return to the flat surface, and
then take another path.
When walking on a gentle slope covered with grass or dead leaves, or when walking on wet
metal plates or frozen ground, the machine may slip. Make sure that the machine does not
stop laterally on a slope.
If the machine stalls on a slope, return the operating levers to the neutral position, and then
restart the engine.
Special Cautions for Operations of Machine on Ice/Snow
While traveling on snowy or icy roads, drive at low speed and avoid the sudden startup, stop, and direction change.
In snowy regions, the road curbs and the roadside objects are buried in the snow to become invisible. In addition, there is a
danger of machine rollover or collision with covered objects. Therefore, always operate with cautions.
There is a danger of rollover or snow entrapment while driving the machine into thick snow. Drive with cautions and do not drive
over road curbs or entrap in the snow.
For frozen soil surface, the ground becomes soft when the temperature rises, which will probably result in rollover of machine
and entrapment of operator in the machine.
While parking the machine on a unstable ground, lower the bulldozing blade.

No Movement of Bucket over Personnel
Moving the bucket over the personnel has a danger of splashing of loaded material
or the sudden falling of bucket.
Guarantee of Driver’s Safety during Loading
Do not load before the driver reaches a safe place.
Do not swing or position bucket above personnel or cab.
Load from the backdoor of trucks.
Keeping a Safe Distance from Overhead
High-Voltage Cables
Never close any part or loaded material of machine to high-voltage cables, unless all
safety measures specified by local and national authorities are already taken. There is
a danger of electric shock and death when any person approaches to the machine that
is discharging electric spark or is near or in contact with power supply.
Always keep a safe spacing between machine and high-voltage cables.
Before starting operations, please verify the relevant operation safety procedures with
local power grid.
Consider all electric cables as high-voltage cables. Even if it’s known or believed that
the power supply is cut off or the cable is clearly grounded, consider such cables also
as live cables.
If the machine is too close to high-voltage cables, set up a signaler to sound warnings.
Keep all personnel within operation zone away from machine and loaded material.
Pay special attention to the underground high- voltage cables.
Close Observation on Dangerous Working Conditions
Never dig on the bottom of any high embankment. It’s really dangerous because such
operation will probably result in surface collapse.
Do not operate in any place with falling stone danger.
Keep a safe spacing between machine and edge of digging site. Do not dig the ground
ahead of machine.
During the operations near a cliff or road curb, to ease the escape in any event, form a
right-angle between tracks and cliff or road curb and place bulldozing blade in the front.
Do not access any soft ground area. This will probably result in inclination of machine
due to dead weight to cause rollover or ground entrapment.

Keep away from unstable ground (Cliffs, road curbs, and deep ditches). If the ground
collapses due to machine weight or vibration, there is a possible danger of machine falling
or rollover. Please bear in mind that the soil turns infirm after heavy rain or explosion.
The ground on the top of embankment and the ground around and on top of the dug
ditches are also infirm.
Do not perform demolition operations beneath the machine. There is a possible falling
danger of machine when the ground becomes unstable.
Before the operations on the top of any building or other structure, check the strength and
structure. It will cause serious harms or destruction if the building or structure collapses.
Do not perform demolition operations above your head. There is a falling damage of
damaged parts or collapse danger of building to cause serious harms or destruction.
Do not perform the demolition operations by the impact force of bucket working
device. The splashed material fragments and the damaged bucket working device
have a danger of serious harms.
Danger during Operations on Slopes
During operations on slopes, slewing or operating the working device can probably
result in instability or rollover of machine.
Avoid operations on slopes whenever possible.
Leveling operation zone
If the bucket is fully loaded with material, avoid slewing towards the down slope
direction. Otherwise, it will deteriorate the machine stability and probably result
in rollover.
No Lateral Slewing (Swing) with Bucket Heavily Loaded
The machine is more vulnerable to rollover in lateral direction than longitudinal
direction.Do not laterally slew (swing) when the bucket working device is heavily
loaded. Especially, do not laterally slew (swing) on a slope. When the machine is
equipped with breaking hammer, grinder, or extended bucket arm, the attachment
end is heavier than that with standard bucket. For machine with such heavy end, do
not face the bucket arm (boom) towards down slope direction for digging or towards
lateral direction for operations.
Landfill

Please pay attention to the objects above your head
During operations under bridges, in tunnels, near cables, or indoors, guard the boom
and bucket arm against impact with any overhead object.
