4.2 MACHINE TRAVELLING
WARNING
・Check the direction of the track frame
before operating the travel levers.
When the track frame faces backward (i.e.,
when the sprocket is at the front), the
direction of the travel lever operation will
be opposite to the direction of the machine
movement.
・Do not allow anyone near the machine.
・Clear the route of any obstructions.
・Check for safety in the vicinity of the
machine, and sound the horn before
starting to move the machine.
・The rear of the machine body is a blind
spot. Be sure to check your surroundings
visually before reversing. The camera
should be used to complement visual
checking.
・Depressing the accelerator pedal while
travelling is dangerous as it will cause the
machine to move suddenly. Be sure to
operate the pedal cautiously.
・When travelling, check that the travelling
alarm operates normally.
・All crane operations are disabled while the
crane is travelling. Stop the machine before
performing crane operations such as
slewing.
If the machine does not travel at the proper
speed in low temperatures, allow it to warm
up sufficiently. If the machine does not travel
at the proper speed due to sand or mud on
the undercarriage, remove the sand and
mud.
When the hook block is in the simple
stowage position, it may be loosened by
vibration during travelling. If this occurs,
simply stow the hook block in the simple
stowage position again.

4.3 CRANE OPERATION
[HOISTING AND LOWERING]
WARNING
・When hoisting a load, the load will shift
forward slightly due to boom deflection.
Notify slinging operators and other workers
in the vicinity.
・If the hook block is over-hoisted, the
overwinding prevention device detects
overwinding and the warning buzzer
sounds intermittently. When the buzzer
sounds, immediately place the right-hand
control lever in the neutral position to stop
the hoisting operation.
・When lowering the hook a long distance
such as for underground work, be sure to
leave at least three turns of wire rope on
the winch drum.
IMPORTANT
・Take care not to lower the hook block
excessively in order to prevent it from
coming into contact with the ground. Doing
so results in irregular winding on the winch
drum.
・When stopping the winch operation, do not
suddenly return the lever to its neutral
position. Doing so may loosen the wire
rope, resulting in irregular winding on the
winch drum.
Operate the right-hand control lever (1) as
follows:
・Lowering: Push the lever forward.
・Neutral: Release your hand from the lever.
The lever will return to the neutral
position and the hoisting/lowering
of the hook block stops.
・Hoisting: Pull the lever toward you.
Adjust the winch hoisting and lowering
speed by varying the stroke of the right-hand
control lever (1) and the depression of the
accelerator pedal (2).

[BOOM DERRICKING]
WARNING
・Operate the right-hand control lever as
slowly as possible.
Especially avoid sudden lever operations
when a load is hoisted, which may cause
the load to sway and hit the machine,
damaging the crane or causing the machine
to topple.
・Drawing in a load or standing it upright by
derricking is prohibited. Be sure to use
hook hoisting to lift loads.
・Lowering the boom increases the working
radius and reduces the rated total load that
can be hoisted. When derricking the boom,
pay extra attention so that the weight of the
load at the lowermost boom position does
not cause overloading.
Operate the right-hand control lever (1) as
follows:
・Lowering: Push the lever outside (right side).
・Neutral: Release your hand from the lever.
The lever returns to the neutral
position and boom derricking stops.
・Raising: Pull the lever inside (left side).
Adjust the boom derricking speed by varying
the stroke of the right-hand control lever (1)
and the depression of the accelerator pedal
(2).
When the boom length display on the
moment limiter display is "6.0 m" or longer,
lowering stops automatically to prevent the
boom angle falling below a horizontal
position.

6/2020 CC1908S-1 Quick operation guide 17
[BOOM TELESCOPING]
WARNING
・Operate the left-hand control lever as
slowly as possible.
Especially avoid sudden lever operations
when a load is hoisted, which may cause
the load to sway and hit the machine,
damaging the crane or causing the machine
to topple.
・Pulling a load laterally or drawing it in by
extending or retracting the boom is
prohibited. Be sure to use hook hoisting to
lift loads.
・Extending the boom increases the working
radius and reduces the rated total load that
can be hoisted. When extending or
retracting the boom, pay extra attention so
that the weight of the load with the boom
fully extended does not cause overloading.
・The hook block will be raised while the
boom is being extended.
If the warning buzzer of the overwinding
detector sounds while extending the boom,
return the boom telescoping lever
immediately to the neutral position and
stop extending the boom.
IMPORTANT
・The hook block will be raised or lowered
while the boom is being extended or
retracted. Always use the winch operation
simultaneously to adjust the hook block
height.
・When the boom is extended for a long time,
the boom retracts slightly due to the
temperature change in the hydraulic oil. If
this occurs, extend the boom as necessary.
Operate the left-hand control lever (1) as follows:
・Extending: Push the lever forward.
・Neutral: Release your hand from the lever.
The lever returns to the neutral
position and the boom telescoping
stops.
・Retracting: Pull the lever toward you.
Adjust the boom extending/retracting speed
by varying the stroke of the left-hand control
lever (1) and the depression of the
accelerator pedal (2).
When the boom extends, the second stage
extends first, then the third stage and finally
the fourth and fifth stages extend
simultaneously.
When the boom retracts, it retracts in the
reverse order of extension.

[SLEWING OPERATION]
WARNING
・The rear end of the machine protrudes
beyond the crawler width. Check for safety
in the vicinity visually and using the multi-
assist view before slewing.
・Check for safety around the machine and
sound the horn before slewing.
・Perform the slewing operation as slowly as
possible. Be sure to start smoothly, slew at
low speed, and stop gently. Especially
avoid sudden lever operations when a load
is hoisted, which may cause the load to
sway and cause the machine to lose
balance, damaging the crane or tip the
machine.
・Pulling a load laterally, drawing it in, or
standing it upright by slewing is prohibited.
Be sure to use hook hoisting to lift loads.
IMPORTANT
The rated total load is the same in all
directions regardless of the slewing stop
position.
Operate the left-hand control lever (1) as follows:
・Left slewing: Push the lever outside
(left side).
・Neutral: Release your hand from the
lever.
The lever returns to the neutral
position and the slewing stops.
・Right slewing: Pull the lever inside
(right side).
Adjust the crane slewing speed by varying
the stroke of the left-hand control lever (1)
and the depression of the accelerator pedal
(2).
There is a horn switch at the centre of the
knob on the right-hand control lever (3). Use
the switch to signal when slewing.
