1 - GENERAL INFORMATION
Product identification
The CX350C — CX380C is a crawler hydraulic excavator. It consists of an undercarriage fitted with tracks and a
turntable bearing which supports the upperstructure frame. The upperstructure frame supports the attachment, at
the front end of the machine, plus the engine, hydraulics and cab. When the operator works the controls, the en-
gine-driven pump delivers hydraulic fluid to the control valves. The control valves distribute the hydraulic fluid to the
various cylinders and hydraulic motors employed. A cooling system maintains the hydraulic fluid at normal operating
temperature.

Cab internal lighting
The room lamp allows to have internal lighting near to the
operator's station. The room lamp has a control switch
with three operating positions:
• OFF
• DOOR
• ON
When the switch is set in DOOR position, the room lamp
turns on automatically when the door is opened, and turns
off automatically when the door is closed.
NOTE: If the door is left open for more than 30 s, the lamp
is forcedly turned off in order to prevent drain of the battery SMIL14CEX2568AA 1
charge.
The ON position of the switch allows to turn on the room
lamp only if the starter key is set in ACC or ON position.
NOTICE: Never leave the room lamp switch in ON posi-
tion. The battery charge may be drained out. As the need
for lighting ends, set the switch to OFF or DOOR position.
Emergency exit hammer
Located on the left-hand cab, use the hammer (1) to break
the rear window, and then push the window strongly and
escape outside.
Consult your CASE CONSTRUCTION dealer for window
installation.
NOTICE: Do not break the rear window except when it is
absolutely necessary, such as to escape in an emergency.
NOTICE: Do not place anything in front of the window.
Doing so may obstruct an emergency escape.

WARNING
Moving parts!
Make sure the lower panels are properly
closed before driving the machine.
Failure to comply could result in death or se-
rious injury.

Located under the upperstructure frame, these panels
provide access to certain machine components.
NOTICE: Do not run the machine with the panels re-
moved.

Windshield washer reservoir
The windshield washer reservoir is located inside one of
the left-hand compartments behind the cab.
Make sure to check the reservoir level each day in order
not to let the windshield washing fluid run out completely.
NOTICE: Never operate the windshield washer when the
reservoir is empty. This wil cause damage to the electric
pump.
NOTE: In cold weather, add anti-freeze to the windshield
washing fluid.
NOTE: The reservoir can be lifted out of its support in
order to ease the maintenance operations.

4 - OPERATING INSTRUCTIONS
Bringing the machine up to operating temperature
Before starting operation, the main systems of the machine shall be warmed up to their normal operating temperature.
NOTE: The normal operating temperature for the hydraulic fluid is 50 – 80 °C (122 – 176 °F) . This corresponds to
four segments lit on the hydraulic temperature gauge.
NOTE: The normal operating temperature for the engine coolant is 75 – 90 °C (167 – 194 °F). This corresponds to
four segments lit on the coolant temperature gauge.
A warm-up procedure shall thus be carried out in order to grant a proper and safe usage of the machine, and in order
to grant the best machine performance and fuel efficiency.
NOTICE: The warm-up of the machine is mandatory when operating in severe winter climates.
NOTICE: The warm-up of the machine prevents wear and severe damages to the engine, to the fuel system and to
the hydraulic system.
NOTICE: The exhaust pipe becomes extremely hot while the engine is idling. Make sure that there is no flammable
material such as plants, dried grass, paper waste, oil and old tires close to the exhaust pipe before starting warm-up
procedure.
NOTICE: Never cover the grids of the radiators with flammable materials.
Automatic machine warm up
Regardless of the ambient conditions, the machine control system allows to carry out an automatic warm-up proce-
dure that brings the temperature of the main operating fluids to the proper level for machine operation.
Start the engine with the speed throttle in the low idle position and let the machine complete the automatic warm-up
procedure. During the automatic warm-up, the engine speed and the engine load are automatically managed in order
to match the warm-up cycle to the ambient conditions and to optimize the warm-up cycle in respect to the machine
operating parameters.
NOTE: the engine speed and the noise of the hydraulics are supposed to change during the warm-up cycle.
NOTICE: The automatic warm-up procedure is the recommended operating practice. However, the automatic
warm-up procedure can be overridden either by changing the engine speed manually or by operating any operation
lever.
As the procedure starts up, the message AUTO WARM UP is displayed:
The automatic warm-up procedure takes about 5 – 10 min depending on the ambient conditions.
After completion of the automatic warm-up procedure, the AUTO WARM UP message disappears, and the engine
speed gets back to low idle.

4 - OPERATING INSTRUCTIONS
Stopping the unit
Stopping the engine
1. Lower the attachment until it is resting on the ground.
2. Turn the engine throttle (1) to low idle position.
3. Let the engine run for about 5 min.
NOTICE: If the engine is stopped suddenly, the lubri-
cated section on the turbocharger gets dried from the
high heat, leading to a turbocharger failure.
4. Turn the starter key (2) to OFF position.
SMIL15CEXY892AB 1
Emergency stop switch
In the event of an emergency or if it is not possible to stop
the engine using the starter key, press the emergency
stop switch on the left-hand console.
NOTE: This switch should only be used in case of an
emergency. Do not use it on a day-to-day basis to stop
the engine.

5 - TRANSPORT OPERATIONS
Loading the machine on a rear loading type
trailer (without front equipment installed)
WARNING
Tip-over hazard!
The counterweight MUST be removed before
transporting the machine without an attach-
ment. Consult you dealer.
Failure to comply could result in death or se-
rious injury.
W0260A
WARNING
Pressurized system!
Before removing the attachment from the
machine, make sure the air pressure and hy-
draulic oil pressure are at zero.
Failure to comply could result in death or se-
rious injury.
W0284A
If the machine has to be transported without the complete
front equipment (boom and arm), the counterweight shall
be removed from the base machine. Loading the base
machine on the trailer with the counterweight installed af-
fects the stability of the base machine itself, and definitely
compromises its climbing ability.
NOTICE: the use of lifting systems is necessary for re-
moval and installation of the machine front attachment
and of the counterweight. Refer to your CASE CON-
STRUCTION dealer for proper removal and installation
procedure.
Select the H work mode.
SMIL13CEX2721AB 5
Align the machine to the trailer, so as the travel motors
face the trailer ramps.
NOTICE: In this position, traveling and steering control
become opposite to each other.
Slowly climb the trailer ramps. Slowly travel on the trailer
bed to reach the resting position.
Slowly turn the upper structure 180°.

6 - MAINTENANCE
• Check the cylinders are not leaking oil.
• Check the condition of all lines.
• Check the condition of the bucket and its tools.
After starting the engine
• Did the engine start correctly? Are the exhaust fumes normal? Any strange noises?
• Check for abnormal noise on the hydraulic components.
• Check the components for signs of leaking oil or water.
• Check the audible alarm devices, working lights and windshield wipers.
• Check that all circuits (travel, swing and tool) are functioning correctly.
NOTICE: if the slightest defect is found, repair it immediately before using the machine or consult your CASE CON-
STRUCTION Dealer.
