To prevent potential damage to the turbochargeryou should:

allow the engine to idle for a period of threeminutes prior to shutting down.This allows the turbo charger to reduce speedand also allows time for the turbine casing tocool down

never rev the engine immediately on start up.Allow a few seconds for oil to reach all parts ofthe engine & turbine bearings

Session 2:

Diesel Particulate Diffuser (DPD)

The DPD is an after treatmentdevice (like an additionalmuffler in the exhaust system)that dramatically reducesParticulate Matter (PM)

The DPD system purifies thecarbon monoxide (CO) andhydrocarbons (HC) dischargedfrom the exhaust and captures

PM in a filter The accumulation of PM is monitored by the engines Electric

Control Module (ECM)

Session 2:

7/29/2019 1_2_4D_Lght_Tnkr_Edn2_1

43/87



The ECM automatically initiates the DPD regenerationprocess which burns the accumulated PM during a 3 to30 minute cycle depending on the internal DPD filtertemperature at the start of the process

The driver is notified that DPD regeneration is inprogress by a green lamp on the dash

Automatic Regeneration

Session 2:

7/29/2019 1_2_4D_Lght_Tnkr_Edn2_1

44/87



If the automatic regeneration process does not occuras a result of abnormal driving conditions, the driver isnotified by a slow flashing orange lamp on the dash

This means the manual regeneration process is

required at your earliest convenience

Session 2:

Manual Regeneration

Session 2:

7/29/2019 1_2_4D_Lght_Tnkr_Edn2_1

45/87



To activate a manual regeneration process:

Pull over in a safe place, apply the hand brake andleave the tanker idling in neutral

Press the DPD switch (mounted on the dash) and wait

for around 20 minutes.

Session 2:

Manual Regeneration

The orange lamp on the dash glows steadily and isextinguished when the regeneration process hasfinished.

Then the tanker can be driven normally.

If the slow flashing orange lamp is ignored it flashesfaster indicating that you are urgently required toperform the manual regeneration process

47/87



Session 2:

Manual Regeneration

If the fast flashing orange lamp is ignored, thenexcessive accumulation of PM will eventually clog thefilter and compromise its operation to reduce emissions

As a result the Engine Control Unit will de-rate theengine to limp mode to reduce the amount of

emissions it can produce and to protect the DPD frompermanent and expensive damage

Limp mode effectively means that only 40-50% of theengines power can be used. That is, your maximumdriving speed would be reduced to somewhere around

40km/h

Session 2:

7/29/2019 1_2_4D_Lght_Tnkr_Edn2_1

48/87



The only way to retain full engine power (remove itfrom limp mode) is to have the truck returned to anIsuzu dealer (on a flat bed tray) so that they canphysically pull apart the DPD, clean it and reset theECM

The manual regeneration process can be interrupted ifthe tanker must be moved

However there is the potential that during low speed,long engine idle periods that a manual regeneration

process will be required. If a manual regeneration process is required during fire

fighting operations, the tanker shall be removed fromthe fire ground and the manual regeneration processactivated

To help mitigate the need to do a manual regenerationprocess on the fire ground, after each shift at thestaging area, and with the engine at normal operatingtemperature, the driver shall try to perform a manualregeneration.

Each time the vehicle is put away, or once per week(whichever occurs first), and with the engine at normaloperating temperature, the driver shall try to perform amanual regeneration.

The engine ECM will only allow a manual regenerationto occur if there is sufficient restriction through theDPD, and therefore may not occur each time it isattempted.

Foam concentrate is storedin 2 x 20 litre carboys

A single foam pick-up tubeis connected to the carboyand supplies foam

concentrate to theproportioning valve

Note:

If the carboy lid is not a vented type, the lid must beunscrewed approx to 1 turn to allow air to enter the carboy.

Failure to loosen the lid will result in a negative pressureforming in the container resulting in reduced concentrate flowto the proportioner

When the Class A foam valve isin the On position water being

used by the branches provides

cooling for the pump by providing

a flow of water through the pump.

During foam production, if branches are turned off, water stops

flowing through the pump and as a result the pump may

overheat.

Note:

When foam is being produced, branches should not be shut offfor more than five minutes while the pump is operating.

Damage to the pump seal is likely to occur after this time due

to an increase of water temperature in the pump.
