reaches at least 10°C (50°F). It is then recommended
that all crane functions be cycled to remove cold fluid
from all components and cylinders of the hydraulic
system. If there is any unusual sound coming from the
crane’s hydraulic pumps or motors, stop the operation
and engine immediately and contact a Manitowoc
distributor.
• From 10°C to 4°C (50°F to 40°F): Crane operation with
a load is allowed with medium engine RPM and medium
function speed (joystick position) until the fluid reaches
at least 10°C (50°F).
• From 95°C to 10°C (200°F to 50°F): Crane operation
with a load is allowed with no restrictions.
• Above 95°C (200°F): No crane operation is allowed. Let
the crane’s hydraulic oil cool by running the engine at
idle with no functions actuated.
Engine Operation
Start-up and shutdown procedures for most diesel engines
are generally the same. Therefore, the following procedures
can be applied, except where specific differences are noted.
(Refer to the applicable engine manufacturer’s manual for
detailed procedures).
Start-Up Procedure
Make an under-the-hood inspection for fuel, oil, and coolant
leaks, worn drive belts, and trash build-up.
Use the correct grade of oil for the prevailing temperature in
the crankcase to prevent hard cranking. Diesel fuel should
have a pour point of 5°C (10°F) less than the lowest
expected temperature. In case of an emergency, white
kerosene can be added to the fuel to bring the pour point
down to the required temperature. This will prevent clogging
of filters and small passages by wax crystals. The addition of
kerosene is NOT recommended for general use.
Ensure Battery Disconnect Switch handle (1) (Figure 3-7) is
in the ON position (handle shown in the OFF position)
Cold Engine
The engine warning and engine stop indicators will illuminate
and go off in sequence after about two seconds (as a check)
when the key is first turned on. If an indicator comes on and
continues to blink after initial start-up, there is a problem that
needs to be corrected. If the engine warning icon is selected,
a screen will open listing the engine error codes.
An engine block heater and grid heater are provided to aid in
cold-starting.
1. Ensure the emergency stop switch is not pressed.
2. Set the parking brake to ON and position the
transmission shift lever to neutral.
NOTE: The engine will not crank unless the transmission
shift lever is in neutral.
NOTE: The engine “wait to start” indicator located on the
top left side of the front console illuminates amber
for a period of time when the ignition is turned to
the on position. The engine should not be cranked
until the indicator turns off.
3. Turn the key to the first position. The CCS screen will
provide data for the various engine systems and alert
the operator to any detected fault codes. Sound the horn
(left of steering wheel) once.
DANGER
Diesel engine exhaust can be harmful to your health. Only
operate the engine in a well ventilated area or vent
exhaust outside.
CAUTION
Never crank engine for more than 30 seconds during an
attempted start. If engine does not start after 30 seconds,
allow starter motor to cool for two minutes before
attempting another start.
CAUTION
If engine does not start after four attempts, correct
malfunction before attempting another start.
