In order to meet the stringent euro-6 emission requirements daffy use a combination of selective catalytic reduction SCR an add blue dosing facility along with the diesel particulate filter DPF to keep the soot level low.

The suit will be burned at high temperatures burning the suit is known as regeneration.

There are three types of regeneration passive using the heat of the engine to burn the sort without using extra fuel.

Passive regeneration will take place during normal running operation without intervention of the driver.

Active mobile wear a small addition of fuel is injected into the exhaust manifold to generate extra heat again no driver intervention is required.

Finally stationary forced wear driver intervention is required most of the collected soot in the diesel particulate filter DPF will burn passively therefore you the driver will most likely never realize this process is taking place.

However if the soot level in the DPF becomes too high the system will start an active regeneration which simply means the addition of a small amount of fuel to help burn off the suit again this will not be noticed by you.

You may notice the high exhaust system temperature or hessed warning becoming active the hessed warning is a reminder that the engine after treatment system has increased in temperature and caution is required.

If stopping and parking up make sure there are no people vehicles animals or combustible materials within 2 metres of the exhaust outlet and that the catwalk is clear.

If your operation isn't supportive of passive regeneration primarily urban multi-drop operations you may be requested via a popup message in the instrument panel that a stationary forced regeneration is required.

Driver or operator assistance is required using the dashboard mounted control switch should this happen then you may need to allow between 45 and 60 minutes depending on the suit loading to complete the regeneration successfully and a countdown timer will keep you informed.

The DPF switch has three functions running off and initiate when in the running position and the vehicle is being driven the system will manage the suit levels automatically and efficiently off allows the regeneration system to be inhibited.

For example when working in enclosed spaces or an oil refinery remember to switch back on when commencing your journey simply following any on-screen prompts regarding regeneration allows you to get on with a job.

You do best however if you choose to ignore the information given then you can expect further warnings along with engine power reduction.

There are four warning levels of static forced regeneration level 1 suit level high level to suit level 2 high level 3 suit filter full an engine power reduction and level 4 suit filter full service required.

It is advisable to carry out a static force regeneration when prompted.

However taking a motorway route with a fully loaded combination at warning levels 1 or 2 will reduce the level of suit in the DPF automatically.

Should you experience a level 3 warning you must carry out a static forced regeneration at your earliest opportunity as motorway driving is no longer an option.

Should you ignore this warning for any reason you will need to seek immediate assistance from your deaf dealer.

At level 4 where it's no longer possible to initiate a stationary forced regeneration using the dashboard mounted switch for you as a driver.

To prevent any unnecessary complications during your day it is very important to avoid levels 3 and 4.

For your benefit you should really carry out a static force regeneration at your earliest opportunity when prompted to do.

So when carrying out a stationary forced regeneration you must prepare the vehicle to ensure this process can be carried out safely.

The vehicle is parked in an outside area with a minimum 2 meter clear space around the exhaust diffuser the park brake is applied the engine is running at idle speed and the vehicle is not left unattended once you have prepared.

The vehicle you need to use the DPF switch to start the process remember if carrying out a stationary forced regeneration this will be recorded as other work.

No matter if you drive an LF CF or XF the process will remain the same once you press a switch you will get a reminder of the safety checks.

Then once confirmed as okay press the switch again a pop-up will inform you that the process has started the revs will increase and the hessed warning will also come on additionally.

For your benefit a countdown timer will give you an approximate duration and once the cycle is complete the hest warning will extinguish and the revs will drop back to idle regeneration is necessary with all new vehicles.

But DAF have designed the management of regeneration to keep driver involvement to a minimum and making any instructions that may appear as simple to follow as possible.
