TMS9000-2 OPERATOR MANUAL OPERATING PROCEDURES
Published 02-21-2019, Control # 611-05
Set the air distribution and ventilation nozzles.
Operation
Adjust the temperature and air flow as preferred by the
operator.
If the truck crane has been exposed to strong sunlight for a
long period of time, for example, the air conditioning system
should initially be operated at the highest blower level with
the engine running.
The door or at least the windows should be left open for a
short while to air thoroughly. The cooling-down procedure
can be accelerated by increasing the engine speed.
If the air-conditioning system is operated continuously, close
the windows and the door to ensure sufficient cooling.
Set the fan to a lower level once the inside temperature has
reached the desired temperature.
Drying the air
You can dry the air in the superstructure Cab.
Switch the air conditioning on – press button (4, Figure 4-13)
– the button will illuminate.
At the heater control panel:
• Press button (2) once, heating on,
• Switch (1) as far as it will go to warm.
• Turn the switch (5) to the required level.
• Button (3) on the Recirculated air symbol – lamp on.
When drying, the air conditioning system and the heating
system work against each other. After drying, switch off the
device that you do not require.
Switching off
Switch the air-conditioning system off:
Press the button (4, Figure 4-13) – button lamp goes out,
If you do not wish air to be circulated, turn the switch (5) to
the off position.
ANTI-LOCK BRAKE SYSTEM (ABS)
The crane has a standard brake system, equipped with an
electronic speed monitoring and control system, Anti-Lock
Brake System (ABS). ABS monitors wheel speed
continuously but is not involved in controlling the wheel
speed unless there is a reduction in traction. In normal
braking applications, the standard air brake system is in
effect.
NOTE: For more information on the ABS/ATC systems
refer to the Service Manual.
There is a sensor installed in each wheel. Due to system
constraints, only axles 2, 3 and 4 are monitored. The first
steer axle has sensors installed but they are not connected.
The sensors transmit information to the EC-60™ Premium
electronic control unit (ECU). The ECU interprets the signals
and calculates wheel speed, wheel retardation and a crane
reference speed. If the calculations indicate a wheel lock-up
situation, a signal is sent from the ECU to the appropriate
ABS modulator valve to reduce braking pressure. During
emergency braking, the modulator valve alternately reduces,
increases or maintains air pressure in the brake chamber to
prevent wheel lock-up.
During emergency or reduced-traction stops, fully depress
the foot brake pedal until the crane comes to a safe stop. DO
NOT PUMP the brake pedal. With the brake pedal fully
depressed, the ABS will control all wheels to provide steering
control and a reduced braking distance.
Although the ABS improves crane control during emergency
braking situations, the operator still has the responsibility to
change driving styles depending on the existing traffic, road
and/or weather conditions. For example, the ABS cannot
WARNING
For proper ABS operation, do not change tire sizes. The
size of the tires installed during production are
programmed into the electronic control unit. Installing
different size tires could result in a reduced brake force,
leading to longer stopping distances, which may cause
serious injury or death.
