messages that follow this symbol to avoid possible injury or death.
The signal words used with the safety alert symbol indicate a specific level of severity of the
potential hazard. All are used as attention-getting devices throughout this manual as well as on
labels fixed to the machine to assist in potential hazard recognition and prevention.
This safety alert symbol and signal word indicates an imminently
hazardous situation which, if not avoided, will result in death or serious
injury.
This safety alert symbol and signal word indicates a potentially
hazardous situation which, if not avoided, could result in death or serious
injury.
This safety alert symbol and signal word indicates a potentially
hazardous situation which, if not avoided, could result in minor or
moderate injury or serious damages of the machine.
This signal word indicates a potentially hazardous situation which, if not
avoided, could result in damages of the machine or reduction of the
service life.
We have made every effort for you to prevent accidents during operation; however, we cannot be
held responsible for predicting every kind of danger in all operating conditions.
It is the owner or user of the machine who is responsible for always paying attention to operate
the machine, as well as reading and understanding this manual enough to obtain the essential
knowledge and skills fundamental to correct machine operation.

SAFETY PRECAUTIONS
PRECAUTIONS BEFORE OPERATION
Read and understand the safety signs and labels
xThere are several specific safety signs on your
machine.
Please read and understand the safety signs and
labels.
xYou must replace a label if it is damaged, missing or
cannot be read.
Make a work plan
Start the work only after discussing with the person in
charge at the site.
Wear proper working clothes
For the sake of safety during working, wear clothes that
match your body.
Always wear required protective items such as protective
cap, protective goggles, reflective clothing, safety shoes,
and ear protection as required.
Watch for underground utilities
Mark the location of underground utilities such as gas
lines, sewers, and power lines before any digging
operations. If necessary, the utilities should be
temporarily discontinued.

SAFETY
30V4 • 35V4 ENG 1-3
Perform "walk-around" inspection
Be sure to walk around the machine and inspect it before
starting work. If some defects are found, repair them
without fail.
Prevent a fire
xDo not leave oiled waste cloth, dead leaves, paper
trash or other flammable objects around the engine.
Such matters may cause a fire. Always inspect and
remove such matters.
xStop the engine and do not bring fire close to it while
refilling fuel.
xCheck if fuel, oil or hydraulic oil does not leak. If some
defects are found, repair them and wipe off leaked oil.
xCheck the installation position and usage of the fire
extinguisher.
Install the ROPS canopy
We recommend that the ROPS canopy should be
installed to avoid accidents, which may result in injury, if a
machine with a canopy should fall down.
Carefully mount and dismount the machine
Always use steps and handholds to mount and dismount
the machine.
Hold the handholds with both hands and face the machine
keeping a contact with at least three points of the steps
and handrails.
Never hold control levers at mounting and dismounting.
Start the engine at the operator's seat
If the engine is started from a position other than sitting in
the operator's seat, there is the danger that the machine
starts moving suddenly.
Start the engine only after carrying out checks while
sitting in the operator's seat.

SAFETY
30V4 • 35V4 ENG 1-4
PRECAUTIONS DURING OPERATION
Stay seated while operating
Never attempt to operate the excavator from any position
except the operator's seat. If you operate the machine
from any other position, such as standing by the window
or door, you may operate the machine inaccurately, which
can cause serious injury. Remember that you should not
get on or off the moving machine to be seated or to leave
the machine.
Fasten the seat belt
If the machine falls down, you may be thrown out of the
operator's seat or pressed under the machine. Such an
accident may result in serious injury or death.
Sit on the operator's seat and fasten the seat belt all the
time while operating the machine.
Clear all personnel from the machine and area
Be sure to barricade the job site to prevent entry of the
unauthorized. Confirm that there is no one around the
machine before starting the engine or operating the
machine.
Prevent accidents while moving
Always sound the horn to signal others nearby that you
are moving the machine. Check that no one is within the
working area of the machine before attempting to move it.

SAFETY
30V4 • 35V4 ENG 1-5
Never swing over personnel
Be sure that no personnel are working around the
machine before swinging.
Pay attention to invisible workers in a trench or pit in
particular. Follow the signal person's direction not to
swing over such workers.
Never leave the bucket in the raised position
Never leave the load suspended in mid air, when the
machine is out of service, or you have to leave the
machine. Always put down the bucket of load onto the
ground. Should a malfunction occur, it could fall, striking
equipment or personnel.
Do not swing above the truck cab
If you swing the bucket above the truck cab, the driver
may be injured by dropped soil and sand or the bucket
contacting the truck cab.
Do not swing the bucket above the truck cab when
loading soil and sand.
Provide adequate tailswing clearance
Confirm that there is a sufficient clearance around the
machine for swinging operation.
The operator tends to be unconscious of the area behind
the machine. Before tailswing, make sure that there are
no personnel or objects in such area.
Always observe the bucket and load
Always watch the moving bucket or load carefully.
Moving bucket or load without care may cause injury to
personnel or materials.
If you have to look away from it, stop the machine.

SAFETY
30V4 • 35V4 ENG 1-6
Never allow unauthorized personnel to ride on the
machine
Only operator is authorized to be on the machine during
operation. Never let unauthorized personnel ride on the
machine. Any person riding as a passenger can fall off
and suffer injury.
Danger for electric power line
If the machine should contact with an electric power line,
move the machine apart from the cable.
If it is impossible to move the machine, shout “Never
touch the shovel” to give a warning to the workers around
the machine.
Do not put on the step when you get off the shovel. Jump
down onto the ground.
Do not operate the engine in an enclosed area without
adequate ventilation
Diesel engine exhaust contains products of combustion
which may be harmful to your health. Always start and
operate the engine in a well ventilated area. If in an
enclosed area, vent the exhaust to the outside.
Do not dig near the machine
Do not dig the ground deep near the machine to prevent
falling due to collapse of the ground.
Do not dig at the base of a cliff
If you dig at the base of a cliff, it may collapse or stones
may drop, causing a danger. Do not dig a cliff.

SAFETY
30V4 • 35V4 ENG 1-7
Never exceed the machine performance
If you use a large bucket that exceeds the machine
performance, the machine may be broken or injury or
death may result.
Be sure to use a bucket or attachment that meets the
specifications.
Never lean out of the window
Do not lean out of the window, enter between the
attachment and cylinder or put your hand or arm between
them.
If the attachment moves, you may be caught by the
attachment, resulting in serious injury or death.

SAFETY
30V4 • 35V4 ENG 1-8
PRECAUTIONS FOR TRAVELING
Check the direction
If forward movement and backward movement are
mistaken in operation with the travel lever, serious
accidents may result.
Check the blade position before traveling. If the blade is
behind the machine, operations of the travel levers are
reversed.
Travel up and down the slope
Traveling sideways or parallel to a slope while on it may
cause the machine to slide and fall over.
To prevent such accidents, only travel up and down the
slope at a right angle.
Do not steer on the slope
Avoid changing the direction on a slope, which could
result in tipping or side slipping of the machine.
When it is inevitable to change the direction, carry it out in
a hard ground where the slope is gradual.
Travel on the slope
xKeep the bucket at as low position as 20 to 30 cm from
the ground and travel the machine at low speed when
traveling on a slope.
xLower the bucket onto the ground and stop traveling if
the machine becomes unstable.
