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.
Add the mixture to the heater diesel fuel tank (1, Figure 3-11)
located on the outside of the cab.
Heater Coolant
The heater coolant bottle (1, Figure 3-12) is mounted to the
air conditioner. The coolant should contain a minimum 50/50
ratio mixture of water and antifreeze to prevent freezing or
slushing.
Hydraulic Suction Pump Shut-off Valve
The hydraulic suction pump (1, Figure 3-13) is located on the
front of the hydraulic tank. The pump features a safety switch
(2) that determines if the shut-off valve is open or shut. The
valve must be fully open to start and operate the crane.
When the valve is closed, the crane will not start. This safety
switch ensures that there is hydraulic fluid available when
running the crane. For more information about the control
states, see “Crane Ignition and Control States” on page 3-3.
When the suction valve is closed, the ESTOP warning
screen appears in the RCL (Figure 3-13). The ESTOP
screen persists until the suction valve is fully open.
To open the valve, turn the handwheel (3) clockwise.
WARNING
Explosion Hazard!
Do not mix gasoline with diesel fuel. Death or serious
injury can occur due to explosion.
