NOTE 1:It is the control to recover the DPF function by automatically
or forcibly burning the soot deposit in DPF. (The idle-up and
exhaust brake is operated during DPF control when the vehi-
cle is stopped.)
2: When the idle status continues for a set time, it is automati-
cally operated whether the PTO switch is turned ON or OFF.
(The idle-up and exhaust brake is operated when the idle
control is turned on.)
3: The agitating trucks have no PTO switch. The DPF control
under operation continues operating. However, it becomes
not operated when the accelerator pedal and the accelerator
for operation (external engine control lever) are operated.
4: The engine speed can be controlled by either the accelerator
pedal or the external engine control lever, whichever can
achieve a higher speed.
2. Functions of junctions A and B
1) If junction A is connected
• The characteristic can be switched to All speeds mode by turning on
the PTO switch.
• The engine speed can be controlled by either the accelerator pedal
or the external engine control lever, whichever can achieve a higher
speed.
2) If junction B is connected
• For vehicles without PTO switch (such as the agitating trucks) the
engine speed can be controlled with the external engine control
lever.
3) If both junction A and B are not connected.
• If the PTO switch is turned on, operations can be performed while
keeping the governor characteristic in the driving mode.
• The engine speed can be controlled with the accelerator pedal, but
it cannot be controlled with the engine control lever.
Cautions:
• Do not connect junction A and junction B at the same time.
• When junction A is connected, always turn off the PTO switch
before driving. Failure to turn off the PTO switch will cause
the governor characteristic to remain at All Speeds, so if is very
dangerous.
• The adjusting bolt of the external engine control lever is already
set before shipping. Do not adjust it.
