CHAPTER 1:
SAFETY
SAFETY INTRODUCTION
Always be alert to the safety precautions within this
manual. Safety precautions are crucial to the operator and
service personnel. Safety precautions describe the actions
necessary to prevent accidents when using the crane. All
operators and service personnel must comply with the
safety precautions in the manual.
In actual operation, risks associated with the crane vary
greatly depending on the conditions such as operation
method, environment at the job site and weather. Therefore,
observe the safety precautions described in the manual
and on the safety labels on the crane. Also pay attention
to anticipate potential risks regarding operation to prevent
accidents and damage to the crane.
Your most important duty is to secure safety for yourself,
co-workers and people around the crane.
BASIC SAFETY RULES
The operator should:
• Have sufcient experience in working with cranes
and be trained and qualied as a crane operator.
• Be in good health, emotionally stable and not subject
to physical disability.
• Not be using any medicine or drug that impairs
physical, visual or mental response.
• Ensure that all personnel who are going to enter the
working area wear a hard hat, safety shoes or gloves,
in accordance with local regulations or in-house
rules.
• Be in good physical condition to be prepared for the
job.
• Master the techniques for safe control of the machine
and be completely familiar with the operation and
maintenance instructions given in this manual.
• Keep the cab, the walkways and any other access
areas free of mud, oil, grease or water. (Also keep the
control console clear of any objects that may obstruct
free operation of the controls.)
• Do not climb on the boom or jib; it is very easy to
fall and be injured. (When working at an elevated
position, use a platform to prevent an accident.)
• When on the crane for inspection or other purposes,
beware of the overhead clearance and watch footing;
take care not to slip and walk on the anti-slip strips
provided; worn anti-slip strips should be replaced.
• Never get on or off a moving machine.
SAFETY DEVICES
The rated capacity indicator (RCI) functions properly only
when used exactly as instructed in the manual supplied
with the machine. Failure to follow the instructions given
there could cause the machine to overturn or be damaged,
leading to a serious accident.
Make sure that the safety devices (RCI, A2B hoist limit
switch, winch third wrap shutdown, etc.) and the alarm
devices are always in good working order. Should any device
malfunction, do not use the machine until it is repaired.
Avoid any act that can impair normal operation of the
vehicle.
A safety device is not a substitute for human skill and
judgment. Safety devices are provided only as an aid to
the operator; they themselves cannot control the machine.
For example, the RCI does not provide a warning when
the crane is on soft, loose ground or when the number of
parts-of-line is insufcient. It cannot predict the effect of
wind, improperly adjusted devices, side loads on the boom,
or any other potentially hazardous condition on the crane.
Many safety devices can assist the operator in achieving
safe results, but the operator should not depend solely on
them to prevent accidents. Operating safety requires all
the qualities of a good operator, including skill, experience,
judgment and safety awareness.

WARNING
Do not operate
HOLD PLANNING MEETING BEFORE WORK
Always make detailed arrangements before the start of
the work with the supervisor, rigging workers and signal
people about the following points listed. Make sure that all
decisions are obeyed. An accident can occur if pre-work
planning meetings are not held or are inadequate.
The following are some of the factors for consideration
during the planning meeting:
• Plan the work based on the rated lifting capacity
table, the mass of the load to be lifted, the lifting
height, the place for loading and unloading, the place
for crane setup, work procedures, rigging method,
etc.
• Check of ground conditions where the crane is set
up, and presence of buried objects such as water or
gas pipes
• Methods of preventing overturning, such as extension
of the tracks and use of steel plates on the ground
• Selection of rigging workers and signal people, and
agreement about the signaling method
• Setting of off-limits zone, fencing and installing ropes
• Check of the work positions for workers
• Always have clear communication established
between the crane operator and any ground
personnel.
◊ If using hand signals, both the crane operator
and any ground personnel must decide on the
hand signals that they will be using during the
job before the work begins.
◊ If hand signals are not used, proper radio
communication must be set up and tested before
the job begins.
• Check of emergency communication methods,
contact addresses and safety and health
organizations in charge
CHECK SAFETY AROUND MACHINE BEFORE STARTING
ENGINE
Before starting the engine always sound the horn to alert
anyone around the machine. Make sure there are no people
or obstacles under or around the machine before you start
the engine. If you start the engine without checking safety
surrounding the machine, machine damage, injury or death
may occur.
KEEP ENGINE SURROUNDINGS CLEAN
Always remove dead leaves, trash, oil and other ammable
objects near the engine before operation. Flammable objects
can cause a re.
BE CAREFUL WHEN REFUELING
Always pay attention when handling fuel, oil and grease.
These are highly ammable and can be dangerous.
Always observe the following precautions when you refuel
the machine.
• Stop the engine.
• Refuel the machine in a well-ventilated, open place.

• Lock all the doors, windows and covers.
PRECAUTIONS DURING OPERATION
CHECK WORK SITE CONDITIONS
Always pay close attention to the surrounding conditions
when operating the crane. Watch for any changes in the
surroundings during work. Unexpected accidents can occur.
Before you start work, check the location in which the crane
operates, the passageways, presence of obstacles, how
other machines are set up, etc.
K1450-00EK1450-00E
PROHIBIT UNAUTHORIZED ACCESS TO WORK SITE
Always make sure there are no unauthorized people or
obstacles in the work site area before you start work.
Designate the work site as an off-limits zone. Take
measures to prevent unauthorized people from gaining
access, such as putting up fencing and assigning a guide
person to prevent accidents while working in a site with
heavy trafc. If unauthorized people or vehicles enter the
work site, accidents such as collisions, injuries or deaths
can occur.
ASSIGN SIGNAL PERSON
Always assign a signal person and make sure that the
instructions from the signal person are obeyed. It is
particularly important in the following cases:
• When working near electricity lines
• When the operator cannot see the lifted load
• When moving the machine into a narrow passage or
in a direction where the view is unclear
• While working jointly with two or more machines
Always use portable radio equipment when possible for
communications between the signal person and operator.

USE SUFFICIENT ILLUMINATION AT NIGHT
Always use work lights when working at night so that
you can clearly see the movements of the machine and
lifted load. Install additional lights to illuminate the areas
surrounding the machine. In a dark, unlit area, people and
obstacles around the crane cannot be easily seen, which
increases the risk of accidents.
K01453-000
OBSERVE CONDITIONS FOR WORK
Always strictly observe the conditions for the work specied
in the rated lifting capacity table. If the track position, boom
length, load radius, etc. are outside of the specications in
the rated lifting capacity table, the machine can overturn
even if a load is not lifted.

NEVER OPERATE CRANE WITH LOAD EXCEEDING RATED
LIFTING CAPACITY
Always check the rated lifting capacity before lifting a load.
The rated lifting capacity differs depending on boom length,
load radius and other factors. Never lift a load exceeding the
values specied in the rated lifting capacity chart. If a load
with a mass that exceeds the rated lifting capacity is lifted,
the machine is overloaded and damage to the machine or
an overturning accident can occur.

USE SAFETY DEVICES CORRECTLY
Always correctly use the safety devices such as the load
moment indicator according to the instructions described in
this manual. If safety devices are used incorrectly or their
functions are obstructed, damage to the machine or an
overturning accident can occur.
PROTECT AGAINST NOISE
Always protect yourself from noise-induced hearing loss
by closing the doors and windows of the operator’s cab
during operation. If you work outside the cab, wear hearing
protection such as earplugs as necessary.
CONDUCT INSPECTION AFTER STARTING ENGINE
Always check the devices and instrument readings after
starting the engine. Make sure that no obstacles or people
are around the machine. Then, under a no-load condition,
check the operation of the control systems, lifting systems
and safety systems. Carry out inspections in a sufciently
large space without people and obstacles around the
machine. Neglecting the inspections after engine start-up
will delay detection of machine abnormalities. This can
cause damage to the machine and injury or death.

CHECK BEFORE LIFTING LOAD
Always check the following points before lifting a load:
• The mass of the lifting load does not exceed the
rated lifting capacity.
• The number of parts of line for the wire rope is set
according to the standard number of parts of line
specied in the rated lifting capacity chart.
• Proper lifting devices are used and the load is rigged
securely.
• The hook block is directly over the center of gravity of
the load.
• The load lines are vertical so that the load is lifted
vertically.
• The safety latch of the hook block functions properly.
• The wire ropes are free of intertwining or disorderly
winding.
SECURELY RIG LOAD
Always use the correct rigging method. If the rigging method
is incorrect, the lifted load can fall and cause an accident.
Observe the following precautions to ensure secure rigging.
• Understand the mass and center of gravity of the
load, and use the lifting devices best suited for the
mass and shape of the load.
• The lifting devices such as wire ropes and chains
must have sufcient strength and be in good
condition with no damage or wear.
• Rig a load directly over its center of gravity so that
the lifted load does not overturn or slip out of the
lifting devices when lifted off the ground. Also, rig a
load properly so that the lifting devices never cross
over each other or intertwine.
• Never rig a load with a single rope. The lifted load
can turn and create a hazard, and the turn of the load
untwists the rope and reduces its strength.
• If a load has sharp corners, apply pads to the corners
to protect the rigging wire ropes and loads from
damage.
CAREFULLY LIFT LOAD OFF GROUND
Always be sure to raise the load just clear of the ground
carefully rst by winch operation. Never lift a load just
clear of the ground by raising or extending the boom.
Such operations can damage the machine and cause an
overturning accident. When you lift a load just clear of the
ground, stop winch for a moment with the rigging ropes
tensioned. Check to make sure that the load is hung above
its center of gravity and that the load does not stick to the
ground or touch other loads or structures. Lift load vertically
and stop when the load is raised by several inches above
the ground to stop the sway of the load. Check to make sure
that the state of rigging is satisfactory, the load is securely
held at the position, and the machine is not overloaded.
Then, continue lifting.
K01456-00EK01456-00E
LIFT SINGLE LOAD ONLY
Always lift only a single load. Never lift two or more loads at
once. Even if the total load mass is within the rated lifting
capacity, the loads can lose balance and create a hazard.
Also, the operator cannot fully concentrate on multiple loads.

NEVER LIFT BURIED LOAD
Never lift objects driven into the ground such as poles or
piles, trees, and objects buried in mud or sand. If you pull
up buried objects, an unexpected load can be applied to the
machine. This can damage the machine and/or cause an
overturning accident.

AVOID OVERLOADING (EXCEEDED CAPACITY)
Always operate the machine with extreme care if a load is
close to the rated lifting capacity. An overloading can occur
when the load sways. If an overload occurs, lower the load
to the ground by winch down operation. When extending
or lowering the boom, be careful of overloading due to the
increase in the load radius.
BE CAREFUL OF SIMULTANEOUS OPERATION OF CRANE
FUNCTIONS
Never carry out a simultaneous operation of crane functions
until you are familiar enough with its operation (see the
following image). Before you are sufciently accustomed
to the machine, an operation warning can occur during
simultaneous operation. During simultaneous operation,
machine movement tends to be slower than those of
independent operations. Conversely, when the simultaneous
operation is switched to independent operation, movement
can become faster. When you carry out simultaneous
operation, always avoid a sudden change in speed.

BE CAREFUL TO AVOID COLLISIONS WITH STRUCTURES
NEARBY
When moving a lifted load, always be careful not to allow
the machine or the load to collide with a building or other
structure. In a site with many such obstacles, post a signal
person and follow the instructions from the signal person to
prevent a collision.

CAREFULLY OPERATE WHILE BOOM IS RAISED HIGH
Always operate carefully when the boom is raised close to
its upper limit angle to prevent the load from colliding with
the boom or jib (see the following image). When the boom is
raised close to its upper limit angle, the horizontal clearance
between a lifted load and the boom is small. If the lifted load
sways in this condition, the load can collide with the boom
or jib. This can damage the boom or jib or the load itself.
K01460-000K01460-000
CARRY OUT DEMOLITION WORK CAREFULLY
Always check the mass and center of gravity of the load
before operation, and decide the lifting method accordingly.
Never lift a structure during demolition work if its mass and
center of gravity are not known.
G05053-000G05053-000
LIFT SUBMERGED LOAD CAREFULLY
Always be extremely careful not to allow overloading to
occur when you lift a load submerged under water (see
the following image). The load contains water and can be
several times heavier than the expected mass. Never lift a
load from water in one quick operation. Drain water while
slowly lifting the load. Even if water is completely drained,
a load raised out of water is much heavier than when it is
buoyant.
K01461-000K01461-000
PAY ATTENTION TO A LONG LOAD
Always be careful when lifting a long load. The load can
turn and collide with rigging workers, the crane itself and
structures around the machine. Attach guide ropes to one
end or both ends of the load and keep the position of the
load, and prevent the load from turning or swaying.

PAY ATTENTION TO THE TURNS OF WIRE ROPES ON WINCH
DRUM
Never allow a wire rope to be completely reeled out from the
winch drum. If a wire rope is completely reeled out from the
winch drum, the load is directly applied to the rope end due
to loss of friction. This can damage or break the wire rope.
Make sure that three or more extra turns always remain
on the winch drum. Be especially careful when the load is
lowered below ground level.
K01463-000K01463-000
NEVER SUSPEND LOADS FOR LONG TIME
Always arrange the work procedure to minimize the load-
lifting time. Avoid keeping a load lifted for a long period of
time.
USE CRANE ONLY FOR ITS SPECIFIED PURPOSES
Always use the crane for its specied application of lifting
objects. Never use the crane for other applications, such as
pushing an object with the boom.
NEVER ADD COUNTERWEIGHT
Never install counterweights other than the ones specied,
or objects substituting as counterweights, onto the machine
(see the following image). Addition of counterweights other
than the specied ones can damage the machine. This also
can affect the backward stability and cause the machine to
overturn to the rear.
K01466-00EK01466-00E
NEVER BECOME DISTRACTED
Never look away from the signal person and lifted load.
Always be sure to concentrate on the crane operation.
Inattentive operation is very dangerous.
NEVER PASS A LOAD OVER A PERSON
Always avoid dangerous operations such as passing a hook
block or a lifted load over a person. Never allow anyone to
enter the area under the boom or lifted load.
