When Operating the Dump Body
CAUTION
• When operating the dump control lever to raise or lower the dump body, make
sure that there are no persons or objects near or above the vehicle.
• Only raise or lower the dump body with the vehicle positioned on a level
surface. Operating the dump body on an inclined surface can lead to the vehicle
toppling over. Such an operation should never be attempted.
• When operating the dump control lever, the vehicle must have come to a
complete stop, the parking brake lever must be fully pulled and you must keep
the brake pedal fully depressed with your right foot.
• Do not operate the dump body when driving.
ADVICE
• The PTO of the AMT model cannot be engaged when the engine speed is
800 r/min or higher to prevent a failure of the system. However, the PTO can
be engaged at engine speeds of up to 1,200 r/min during diesel particulate
defuser (DPD) regeneration or upon startup of a cold engine (when the quick-
warm system is activated). The PTO cannot be engaged during fast idle control
immediately after cold engine startup or when the engine speed is increased
with the idling control knob. Wait until engine warm up completes or return the
idling control knob to the lowest setting before operating the PTO switch.
• While operating the PTO of the vehicle equipped with DPD, the DPD system
will continue to filter the exhaust and accumulate soot. The engine control
system, depending on the speed and load being applied by the PTO, may
not be able to generate enough energy or adequate heat needed to clean or
regenerate the filter. Continued operation under conditions that do not allow
effective regeneration or cleaning will eventually plug the filter and result in
reduced power. The check engine warning light will be displayed, and dealer
service will be required to return the vehicle to normal operation. To prevent
this from occurring, frequently monitor the vehicle during PTO operation, paying
particular attention to the DPD manual regeneration indicator light (amber) if the
vehicle is not equipped with multi-information display (MID) or the "PUSH DPD
SWITCH" message (amber) if the vehicle is equipped with MID.
NOTE
[Fast idle control]
• A supplementary function to warm up the engine by automatically increasing the
idling speed while the engine is cold.
