• Travel with the dozer blade raised, the hoe
attachment folded as shown on the figure
above, and the bucket raised 30 to 40 cm
(12 to 16 in.) above the ground.
• Do not slew while traveling. If you must
operate the hoe attachment while traveling,
operate at speeds slow enough so you
have complete control at all times.
• Avoid crossing over obstacles whenever
possible. If you must do so, keep the hoe
attachment close to the ground level and
travel slowly. Never cross obstacles which
will tilt the machine to an angle of 10° or
greater.
• On uneven ground, maintain the low speed
and avoid starting, stopping or changing
directions abruptly. Otherwise, the working
equipment may come in contact with the
ground, causing the machine to lose its
balance and get damaged or to damage
the structures in the surrounding area.
1-15
Safety
PRECAUTIONS WHEN OPERATING
Cautions on traveling on slopes
When traveling on slopes or grades, be
careful that the machine does not tip (roll)
over or slide.
• Never travel on slopes that are too steep
for the machine to maintain its stability
(maximum gradeability: 30°, lateral tipping
angle: 10°). Note that in reality, the
machine’s stability becomes lower than the
above values depending on the working
condition.
• When traveling on slopes or grades, drive
slowly in 1st (low) speed. When
descending a slope, slow down the engine
speed.
• Do not descend slopes in reverse.
• Do not change directions on slopes or
traverse slopes. First return to a flat
surface, and then take an alternative path.
• The machine may slip sideways even on a
slight slope if the ground is covered with
grass or dead leaves, or when traveling on
a wet metal plate or frozen surfaces. Make
sure the machine is never positioned
sideways on slopes.
• If the machine is stalled on the slope,
return each operating lever to the neutral
position before restarting the engine.
• When climbing a hill, keep the operator’s
seat facing the hillside. When descending a
hill, keep the operator’s seat facing the
downhill direction. In either case, travel
must be done while paying attention to the
ground in front of the machine.
• When traveling on slopes, lower the bucket
to a height of 20 to 30 cm (8 to 12 in.)
above the ground. When climbing a steep
slope, extend the hoe attachment to the
front. In emergencies, lower the bucket to
the ground and stop the machine.
1-16
Safety
PRECAUTIONS WHEN OPERATING
Operate the machine on snow or ice with
extra care
• When traveling on snow or on frozen
surfaces, drive at a low speed and avoid
starting, stopping or changing directions
abruptly.
• In the snowy area, the road shoulder and
objects placed beside the road are buried
in the snow and cannot be seen. There is a
hazard of the machine tipping over or
hitting covered objects, so always carry out
operations carefully.
• If the machine enters deep snow, there is a
hazard that it may tip over or become
buried in the snow.
Be careful not to drive beyond the road
shoulder or to get trapped in a snow drift.
• With frozen ground surfaces, the ground
becomes soft when the temperature rises,
and this may cause the machine to tip
over, resulting in an operator trapped inside
the machine.
• When parking the machine on an unstable
ground, lower the dozer blade.
Do not move the bucket over the heads of
people
Ensure driver’s safety when loading
Do not load a truck unless the truck driver is
in a safe place.
• Never swing or position the bucket over a
person or the cab room.
• Load the truck from the rear.
Moving the bucket over the heads of people
entails the danger of the load spilling or the
sudden dropping of the bucket.
1-17
Safety
PRECAUTIONS WHEN OPERATING
Keep a safe distance from the overhead
high-voltage cables
Never bring any part of the machine or
loaded material to near to the high voltage
cables unless all safety precautions required
by the local and national authorities have
been installed. If a person comes near to the
machine that is discharging sparks or
located near to or in contact with the power
source, there is a hazard of electric shock
and death.
• Always maintain a safe distance between
the machine and the high-voltage electric
cable.
• Check with the local power company
about safe operating procedure before
starting operations.
• Consider all cables to be high-voltage
cables and treat all cables as energized
even though it is known or believed that
the power is shut off and the cables are
visibly grounded.
• Use a signal person to give warning if the
machine approaches too close to the
high-voltage electric cables.
• Caution all personnel in the work area not
to come close to the machine or the
loaded material.
• Pay also careful attention to the highvoltage electric cables buried underground.
1-18
Safety
PRECAUTIONS WHEN OPERATING
Watch out for hazardous working
conditions
• Never undercut a high bank. Doing so is
dangerous as it may cause ground
collapse.
• Do not operate in places where there is a
danger of falling rocks.
• Do not enter areas where there is soft
ground. Doing so could cause the machine
to tilt under its own weight, resulting in a
machine tipping over or sinking into the
ground.
• Maintain a safe distance between the
machine and the edge of the digging site.
Do not dig the ground under the front of
the machine.
• When working close to the cliffs or road
shoulders, to make it easier to escape if
there is any problem, set the crawlers at
right angles to the cliff or road shoulder and
the dozer blade to the front when carrying
out operations.
• Do not come close to unstable grounds
(cliffs, road shoulders, deep ditches). If the
ground should collapse under the weight
or vibration of the machine, there is a
hazard that the machine may fall or tip
over.
· Remember that the soil after heavy rain
or blasting is weak.
· The ground of top of the embankment
and of the circumferences of the
excavated ditches are also weak.
1-19
Safety
PRECAUTIONS WHEN OPERATING
• Do not perform demolition work under the
machine. There is a hazard that the
machine may fall down, because the
ground becomes unstable.
• When working on or from the top of
buildings or other structures, check the
strength and the structure before starting
operations. If a building or structure
collapses, serious injury or damage will
result.
• Do not use the impact force of the hoe
attachment for breaking work. There is a
hazard of serious injury being caused by
flying pieces of broken materials and by the
damaged hoe attachment.
• When doing demolition work, do not
perform demolition above your head. There
is a hazard of broken parts falling or of the
building collapsing and causing serious
injury or damage.
1-20
Safety
PRECAUTIONS WHEN OPERATING
Operating on slopes is dangerous
When operating on slopes or grades, slewing
or operation of working equipment may
cause the machine to lose stability and tip
over. Avoid operating on slopes whenever
possible.
• Level off the work area.
Never slew (swing) sideways with a heavy
load
The machine can tip over more easily in the
lateral direction than in the longitudinal
direction.
• Do not slew (swing) sideways with a heavy
load at the tip of the hoe attachment. In
particular, do not slew (swing) sideways on
slopes.
• The tip of the attachment is heavier for
machines equipped with breakers,
crushers or long arms than for machines
equipped with the standard bucket. For
such machines with heavier tips, do not
perform excavation with the digging arm
(boom) facing the downhill direction or
operate toward sideways.
• Avoid slewing to the downhill direction with
the bucket full of loaded material. This will
reduce the stability of the machine and
may result in tipping over.
Be careful with the overhead objects
When operating under bridges, in tunnels,
near electric cables or indoors, be careful not
to let the boom or arm hit overhead objects.
1-21
Safety
PRECAUTIONS WHEN OPERATING

Safety
PRECAUTIONS ON MAINTENANCE
Be careful with hot cooling systems
Do not remove the radiator cap or the drain
plug when the cooling water is hot. Stop the
engine and wait until the engine and the
cooling water cool. Then, slowly loosen the
radiator cap to release the internal pressure
and remove it.
Be careful with oil internal pressure
Pressure is maintained in the hydraulic circuit
long after the engine has been shut down.
• Completely relieve the internal pressure
before performing maintenance work.
Release pressure before working on the
hydraulic system
Oil may spurt out if caps or filters are
removed or pipes are disconnected before
releasing the pressure in the hydraulic
system.
• Gradually loosen the vent plug to relieve
tank pressure.
• When removing plugs or screws, or when
disconnecting hoses, stand to the side and
loosen them slowly to gradually release the
internal pressure before removing.
• Oil or plug may spurt out according to the
pressure in the travel motor case. Loosen
the plug slowly and release the internal
pressure.
Be careful with debris when the hammer
is being used
When using a hammer, pins may fly out or
metal particles may be scattered. This may
lead to serious injury.
• If hard metal parts such as pins, bucket
teeth, side cutter or bearings are hit with a
hammer, wear protective gear such as
safety goggles and gloves.
• When hitting pins or bucket teeth, always
check that there is no one in the
surrounding area.
• The hydraulic oil is high enough pressure to
penetrate the skin or eyes and cause
serious injury, blindness or death.
Remember that the hydraulic oil escaping
from a small hole is almost invisible. When
checking for leaks, wear protective goggle
and thick gloves, and use a paperboard or
plywood to keep your skin from oil
spurting.
If oil penetrates the skin, it must be
surgically removed within a few hours by a
doctor familiar with this type of injury.

Safety
PRECAUTIONS ON MAINTENANCE
Disconnect the battery wiring
Disconnect the battery wiring before working
on the electrical system or doing electric
welding. Disconnect the negative (–) battery
cable first. When reconnecting, connect the
negative (–) battery cable last.
Use caution when handling batteries
• Batteries contain sulfuric acid which will
damage the eyes or skin in case of
contact.
· If eye contact occurs, flush immediately
with clean water and get prompt medical
attention.
· If accidentally swallowed, drink large
quantities of water or milk and call a
physician immediately.
· If acid contacts skin or clothing, wash off
immediately with a lot of water.
• Wear protective goggle and gloves when
working with batteries.
• Batteries generate flammable hydrogen
gas which may explode. Keep away from
flame, sparks, fire or lighted cigarettes.
• When checking the level of the battery
fluid, use a flashlight.
• Be sure to stop the engine by turning off
the starter switch before inspecting or
handling the battery.
• Be careful not to let metal tools or any
metal objects come into contact with the
battery terminals and cause a short circuit.
• Loose battery terminals may result in
sparks. Be sure to fasten terminals tightly.
• Make sure the battery caps are tightened
securely.
• Do not charge a battery or jump-start the
engine if the battery is frozen; otherwise it
may explode. Warm the frozen battery to
15°C (60°F) before use.
• Do not use the battery when the fluid level
is below the lower level limit. Doing so will
hasten the deterioration of the internal
portions of the battery and shorten the
battery life. It also can cause rupturing
(explosion).
• Do not add the distilled water above the
upper level limit. Doing so could cause the
fluid to leak. This fluid can cause skin
damage if contacted, or can cause the
machine components to corrode.
• Use a dampened cloth to clean around the
fluid level line and check the fluid level. Do
not clean with a dry cloth; otherwise it
could cause static electricity to build up,
resulting in ignition or explosion.

Connecting the hydraulic circuits
To connect the attachment hydraulic lines,
observe the following procedures:
1. Release the pressure remaining in the
lines, and then close the stop valve.
Refer to “Releasing the residual pressure”
on page 2-43.
2. Remove the plugs.
3. Connect the attachment hydraulic lines to
ports (a/c) and (b/d). When installing a
hydraulic breaker, connect the supply
circuit to the port (a) and the return circuit
to port (b).
4. Open the stop valves. When installing a
hydraulic breaker, open the selector valve
(1). Refer to “Selector valve (Option)” on
page 2-44.
5. When connecting is complete, purge air
from the hydraulic lines.
a. Start the engine and run it at a low idle
speed with no load for 10 minutes.
b. With the engine running in low idle,
operate the auxiliary hydraulic switches
repeatedly (approx. 10 times) to purge
air from the hydraulic lines.
c. Stop the engine and wait for at least 5
minutes until bubbles escape from the
hydraulic oil in the tank.
IMPORTANT: Follow the procedures for
purging air as instructed by the
attachment manufacturer, if applicable.
6. Check for oil leaks.
Disconnecting the hydraulic circuits
1. Release the pressure remaining in the
lines, and then close the stop valve.
Refer to “Releasing the residual pressure”
on page 2-43.
2. Disconnect the lines from the ports (a/c)
and (b/d).
3. Install the plugs.

Releasing the residual pressure
After the auxiliary hydraulic circuits have
been used, pressure remains in the circuits.
This is called the residual pressure. Release
this residual pressure before disconnecting
the lines.
1. When the engine is stopped, depress the
auxiliary hydraulic pedals from side to side
several times.

attachment (2-way flow)
Change the direction of the hydraulic oil flow
by opening or closing the selector valve (1)

Second auxiliary hydraulic switch
Slider switch
(Proportional control)
Proportional control allows for slow-to-fast/
fast-to-slow movement of attachment.
Example: If you move the slider switch half
way, the attachment will move at
approximately one-half the speed.
Third auxiliary hydraulic switch and
button
The third auxiliary hydraulic lines are normally
used to control the “quick attachment”
installed to connect/disconnect the bucket.
When the safety lock lever is released after
the engine is started, hydraulic oil flows into
the pipe (e). This allows the pressure in the
(e) side to increase and to prevent the pin
inserted on the bucket from coming out. If
the pressure in the (e) side drops, the alert
that the bucket may come out is indicated by
the warning lamp and the alarm. For a safety
reason, the bucket can be disconnected only
when the button (1) and the switch (2) are
pressed at the same time. When they are
pressed, the hydraulic oil flows into the line (f)
to increase the pressure there. As the result,
the pin on the bucket comes out and the
bucket is removed from the machine.
Move this switch to control the flow of the oil
in the second auxiliary hydraulic lines.
(C): .... Hydraulic oil flows to the left auxiliary line (c).
(D): .... Hydraulic oil flows to the right auxiliary line (d).

Adjusting the stroke of auxiliary hydraulic
pedal
When a breaker is used, the pedal stroke
must be adjusted so as not to activate the
right auxiliary hydraulic line even if the B side
of the pedal is accidentally depressed.
When a general attachment is used, the
pedal stroke must be readjusted. Adjust it so
that the right auxiliary hydraulic line is
activated when the B side of the pedal is
depressed.
