1300A OPERATORS MANUAL CONTROLS AND OPERATING PROCEDURES
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
temperature, opposite to decrease. The temperature
range is from 46°F (8°C) to 93°F (34°C). The heater
cycles between High, Medium, and Low modes to keep
the temperature setting.
• The FAN ON switch (5) turns on the fan without heat for
air circulation to ventilate the cab. The blue LED (4) is on
when the heater is in the ventilation mode.
• The OFF switch (3) shuts the heater down. If the heater
is in heat mode, the shutdown cycle is initiated and the
fan continues to run for about four minutes after the
igniter goes out.
NOTE: If the heater is turned off and back on, the heater
completes the shut down cycle before initiating the
start up cycle.
Heater Cold Weather Fuel Mixture
At temperatures below 20° F (-7° C), add a cold weather
additive or mix kerosene with the diesel fuel at a 50/50 ratio.
Air Conditioner Controls (Optional)
The air conditioner (A/C) is controlled by two toggle switches
on the crane cab console (Figure 3-6).
The FAN switch sets the fan speed and the A/C switch
controls the air conditioner. The fan speed can be set to LO
(low), MED (medium), or HI (high). Both the fan and air
conditioner are on when the A/C switch is in the COOL
position. Only the fan runs when the switch is in the FAN
position.
Turn the fan switch to the HI position and the A/C switch to
COOL when the air conditioner is first turned on. When the
cab is comfortable, adjust the temperature by turning the fan
switch to the low or medium position.
If the compressor cycles for only a few seconds at a time
when the unit is first turned on, set the fan switch to the low
position until the compressor continues to run. Then
gradually switch to medium and high.
OPERATING PROCEDURES
You need to be familiar with the safety precautions outlined
in SECTION 2 before operating the crane.
Equipment Familiarization
All members of the crew should become familiar with the
location and operation of the controls, the correct operating
procedure, the maximum lifting capacities, and the Safety
Precautions in Section 2 of this manual. Carefully follow the
operating procedures outlined below and the information in
the load charts located in the crane cab.
Crane Cab Access
Pull the ladder out from under the crane cab door before
entering the crane cab. Do not try to access the crane cab by
other means. Take all precautions not to fall off the crane.
Falling from any elevation can cause serious injury or death.
Equipment Checks
Prior to placing the unit in operation, do a complete walk-
around visual inspection and look for structural damage,
loose components, leaks, or other conditions that requires
immediate correction for safe operation. The following
