INTRODUCTION
Read this manual carefully to learn how to operate and
service your machine correctly. Failure to do so could
result in personal injury and/or machine damage.
This standard specification machine can be operated
under the following conditions without being modified.
Atmospheric Temperature: -20 °C to 50 °C (-4 °F to 122 °F)
Altitude: 0 m to 2000 m (0 ft to 6600 ft)
In case the machine is used under conditions other than
described above, consult your authorized dealer.
This manual should be considered a permanent part of
your machine and should remain with the machine when
you sell it.
This machine is of metric design. Measurements in this
manual are metric. Use only metric hardware and tools as
specified.
• SI Units (International System of Units) are used in
this manual.
For reference MKS system units and English units are
also indicated in parentheses after the SI units.
Example : 24.5 MPa (250 kgf/cm², 3550 psi)
Right-hand and left-hand sides are determined by
facing in the direction of forward travel.
Write product identification numbers in the Machine
Numbers section. Accurately record all the numbers
to help in tracing the machine should it be stolen.
Your dealer also needs these numbers when you order
parts. If this manual is kept on the machine, also file the
identification numbers in a secure place off the machine.
Use only diesel fuel with quality specified in JIS K-2204,
EN-590 or ASTM D-975 which contents 15 ppm or lower
sulfur.
Also use fuel that complies with solid contamination level
of class 18/16/13 of ISO4406-1999 (solid contamination
includes dust). If the fuel specified above is not used,
exhaust gas that exceeds the regulation values may be
discharged, causing serious problem on the engine.
Consult your authorized dealer.

General Precautions for Cab
• Before entering the cab, thoroughly remove all dirt and/or
oil such as mud, grease, soil or stones that may mess up
the cab from the soles of your work boots. If any controls
such as a pedal is operated while with dirt and/or oil on
the soles of the operator’s work boots, the operator’s foot
may slip off the pedal, possibly resulting in a personal
accident.
• Do not mess up around the operator’s seat with parts,
tools, soil, stones, obstacles that may fold up or turn
over, cans or lunch box. The levers or pedals become
inoperable if obstacle jams in operation stroke of the
travel levers/pedals, pilot control shut-off lever or control
levers/pedals, which may result in serious injury or death.
• Avoid storing transparent bottles in the cab. Do not
attach any transparent type window decorations on
the windowpanes as they may focus sunlight, possibly
starting a fire.
• Refrain from listening to the radio, or using music
headphones or mobile telephones in the cab while
operating the machine.
• Keep all flammable materials and/or explosives away
from the machine.
• After using the ashtray, always cover it to extinguish the
match and/or tobacco.
• Do not leave cigarette lighters in the cab. When the
temperature in the cab increases, the lighter may
explode.
• Use proper floor mat dedicated to the machine. If another
floor mat is used, it may be displaced and contact with
the travel pedals or control pedals during operation,
resulting in serious injury or death.

Use Handholds and Steps
•Falling is one of the major causes of personal injury.
• When you get on and off the machine, always face the
machine and maintain a three-point contact with the
steps and handrails.
• Do not use any controls as hand holds.
• Never jump on or off the machine. Never mount or
dismount a moving machine.
• Be careful of slippery conditions on platforms, steps, and
handrails when leaving the machine.
• Never get on and off the machine with tools in your
hands.
Adjust Operator’s Seat
•A poorly adjusted seat for either the operator or the
work at hand may quickly fatigue the operator leading to
misoperations.
• The seat should be adjusted whenever changing the
operator for the machine.
• The operator should be able to fully depress the pedals
and to correctly operate the control levers with his back
against the seat back.
• If not, move the seat forward or backward, and check
again.
• Adjust the rear view mirror position so that the best rear
visibility is obtained from the operator’s seat. If the mirror
is broken, immediately replace it with a new one.
Ensure Safety Before Rising From or Leaving
Operator’s Seat
• Before rising from the operator’s seat to open/close either
side window or to adjust the seat position, be sure to
first lower the front attachment to the ground and then
move the pilot control shut-off lever to the LOCK position.
Failure to do so may allow the machine to unexpectedly
move when a body part unintentionally comes in contact
with control levers/pedals, possibly resulting in serious
personal injury or death.
• Before leaving the machine, be sure to first lower the
front attachment to the ground and then move the pilot
control shut-off lever to the LOCK position. Turn the key
switch OFF to stop the engine.
• Before leaving the machine, close all windows, doors, and
access covers and lock them up.

Fasten Your Seat Belt
•If the machine should overturn, the operator may become
injured and/or thrown from the cab. Additionally the
operator may be crushed by the overturning machine,
resulting in serious injury or death.
• Prior to operating the machine, thoroughly examine
webbing, buckle and attaching hardware. If any item is
damaged or worn, replace the seat belt or component
before operating the machine.
• Be sure to remain seated with the seat belt securely
fastened at all times when the machine is in operation to
minimize the chance of injury from an accident.
• We recommend that the seat belt is replaced every three
years regardless of its apparent condition.
Move and Operate Machine Safely
•Bystanders can be run over.
• Take extra care not to run over bystanders. Confirm the
location of bystanders before moving, swinging, or
operating the machine.
• Always keep the travel alarm and horn in working
condition (if equipped). It warns people when the
machine starts to move.
• Use a signal person when moving, swinging, or operating
the machine in congested areas. Coordinate hand signals
before starting the machine.
• Use appropriate illumination. Check that all lights are
operable before operating the machine. If any faulty
illumination is present, immediately repair it.
• Ensure the cab door, windows, doors and covers are
securely locked.
• Check the mirror and the monitors in the CAB for
problems. If there are, replace the problem parts or clean
the mirror, camera and monitor.
Refer to Back Monitor Settings section on the cleaning of
the camera and monitor.
Handle Starting Aids Safely
Starting fluid:
•Starting fluid is highly flammable.
• Keep all sparks and flame away when using it.
• Keep starting fluid well away from batteries and cables.
• Remove container from machine if engine does not need
starting fluid.
• To prevent accidental discharge when storing a
pressurized container, keep the cap on the container, and
store it in a cool, well-protected location.

• Before starting the engine, confirm the safety around the
machine and sound the horn to alert bystanders.
Jump Starting
•Battery gas can explode, resulting in serious injury.
• If the engine must be jump started, be sure to follow the
instructions shown in the “OPERATING ENGINE”chapter in
the operator’s manual.
• The operator must be in the operator’s seat so that the
machine will be under control when the engine starts.
Jump starting is a two-person operation.
• Never use a frozen battery.
• Failure to follow correct jump starting procedures could
result in a battery explosion or a runaway machine.
Keep Riders off Machine
•Riders on machine are subject to injury such as being struck
by foreign objects and being thrown off the machine.
• Only the operator should be on the machine. Keep riders
off.
• Riders also obstruct the operator’s view, resulting in the
machine being operated in an unsafe manner.
