1400A OPERATORS MANUAL OPERATING CONTROLS & PROCEDURES
Boom Lift Control Lever
The boom lift control lever (16) is located on the right armrest
and is used to raise and lower the boom. Push the lever
forward to lower the boom and pull back to raise the boom.
Boom Lift Control Pedal (Optional)
The boom lift control pedal is located on the cab floor and is
used to raise and lower the boom. Rock the pedal forward to
lower and back to raise the boom.
Foot Throttle
The foot throttle (8) is located on the crane cab floor and is
used to control the engine speed. Depress the foot throttle to
accelerate the engine speed and release to return to idle.
Hand Throttle
The hand throttle (2) is located on the crane cab console.
Pull out and rotate to lock to accelerate engine. Turn to
unlock and push in to return engine to idle speed.
Radio Remote Switch (Optional)
The radio remote switch (11) is used to enable the radio
remote controls. The crane function power switch, crane
ignition, and truck igniton must all be OFF before the crane
can be operated with a radio remote control.
Handheld Outrigger Controls (Optional)
The handheld outrigger controls (Figure 3-1) are stored in
the crane cab and are used for outrigger operation from the
crane cab.
Load Chart
The load chart is stored in a pocket in the crane cab. The
load chart contains lifting capacities of the crane in all
allowable lifting configurations.
Rated Capacity Limiter (RCL)
The RCL provides the crane operator with the information
required for the crane to perform safely within its design
parameters. The RCL console (1) displays information on
length and angle of boom, working radius, rated load, and
total weight being lifted.
The RCL continuously monitors these parameters and
provides the operator with an updated readout of the crane
status. If a nonsafe condition is approached, the RCL warns
the operator with an alarm and locks out the crane functions
that can aggravate the situation.
CRANE CAB CLIMATE CONTROLS
The cab climate controls (15, 18) (Figure 3-3) are used to
adjust the heating and air conditioning for operator comfort.
Diesel Heater Controls
The diesel heater controls (Figure 3-5) are as follows:
• The heat START switch (2) ignites the heater. The start
sequence is:
- The heater ignites and the fan starts at low speed.
- The heater operating temperature is reached and
switches to the boost mode.
- The fan speed increases.
• The red LED (1) is on when the heater is in the heat
mode.
NOTE: It takes about two minutes for the heater to reach
operating temperature when first turned on.
If the heater fails to ignite, check the fuel and the
fuel line stopcock.
• The temperature control knob (6) regulates the cab
comfort level. Turn the knob clockwise to increase the
DANGER
The RCL only aids the operator when properly
programmed with the proper load chart and crane
configuration. To prevent injury or death to personnel, be
sure the RCL is programmed before crane operation.
