so you’ve got this conventional model Mack truck with 2010 emissions to drive what do you need to do to get this truck from point A to point B without having a problem on the road here’s the basics as compared to many other trucks the main differences you’ll notice are the de f tank and the scr catalyst if you haven’t been in a truck with any exhaust after-treatment before you may also be unfamiliar with the DPF or diesel particulate filter the DPF filters out the fine particulates in diesel exhaust the particulate collected need to be burned off in a process called regeneration or reject this keeps the filter clean enough to continue filtering properly in oh seven emission trucks the driver had to initiate a region when the truck indicated the filter was full for these 2010 conventional models that activity is likely to be a thing of the past so we’re not going into any details here if you want to know more about it refer to the operator’s manual and the visor label SC R stands for selective catalytic reduction the SCR catalyst is added to the exhaust system to reduce the NOx emissions from the vehicle NOx are various combinations of nitrogen and oxygen in the exhaust you don’t have to worry much about the SCR catalyst as long as you don’t plug it up by doing the wrong thing with the de F we’ll cover the mistakes to avoid a bit later for now just remember that this catalyst will get hot in operation and will stay hot for quite a while after the engine stops so avoid touching or standing on it with its blue cap the de F tank is easy to spot de f stands for diesel exhaust fluid and is sometimes called death de F is needed to work with the SCR catalyst to read ooh snots it sprayed into the exhaust stream through an injector after the DPF and before the scr catalyst de f is a refined chemical product that contains about 68 percent purified water and 32 percent urea urea is an organic compound and is used in many ways in industry and agriculture d EF does not contain any diesel fuel and is not a diesel fuel additive he it’s got its own tank and is the only stuff that should go into that tank if there is one important thing to remember about these trucks it’s don’t mess with the death there’s a gauge in the truck to show the d EF level if you don’t want to experience any engine D rates or vehicle speed limitations you can’t let this tank get low you certainly don’t want it empty if you see indications like this on the truck you’re going to have problems this indicator is the symbol for de F if it’s lit steadily then begins flashing your truck is going into de-rate more importantly if you fill with diesel and forget to fill a critically low de F tank your truck is only going to go 5 miles per hour yes that is 5 miles per hour until you put some de F in that tank the visor label in the cab will tell you what all of the de F indicators mean bottom line pay attention to the gauge while driving and fill the tank when needed this will usually be needed about every other fuel tank fill if you’re just starting out check the gauge and the dash to see if the de F indicator is lit if low or the indicator is on or both fill the de F tank if the indicator goes out drive the truck if it stays on the truck has to be serviced when you do fill use only certified de F from an approved dispenser or a sealed container don’t even think about putting

anything else in the tank no straight water no diesel oil gas or any type of petroleum product no homemade farm made or chemistry teacher made mixes no recycled human or animal liquid wastes and no cleaners solvents or soaps in addition don’t use containers funnels pumps or dispensers that were previously used to handle any other liquids oils fuels coolants cleaners or solvents to store or dispense de F keep the de F handling items specific to de F and de f only using anything other than pure certified de F from an approved manufacturer means that you will shorten the life of the SCR catalyst or clog or poison it so that it doesn’t work and petroleum products cleaners and solvents will damage the de F pump and lines in addition when filling you have to keep everything clean clean clean wipe off the cap area if needed and make sure the container or nozzle is clean no dirt paper or cloth fibers or foreign particles of any kind should be allowed in the tank don’t introduce anything into the de F tank that is not de F how can you be sure you’re getting the right stuff look for this symbol on the label or on the dispenser to be on the safe side it’s not a bad idea to carry an extra container in the truck with you note the size of the de F fill hole it won’t accept the dispenser nozzle for diesel or gas it’s too small de F isn’t harmful or even considered a hazardous material treated as you would treat working with household ammonia avoid skin or eye contact don’t drink this stuff don’t breathe the fumes directly or in an enclosed area if some does get on you flush the area with large quantities of water and wash with soap and water be aware of the various locations where de F is flowing on the vehicle all hoses and connection points should be inspected for leakage during a pre-trip inspection when it dries de F leaves a white powdery residue so it’s not just liquid coming out that you should look for here are the areas to check at the connections to the ser pump assembly at the de F injector in the exhaust and at the exhaust clamps between the DPF and the SCR catalyst because de F can freeze at about 12 degrees Fahrenheit or colder the hoses to the injector are electrically heated the tank and the injector are also heated or in the injectors case cooled by engine coolant with this in mind look for coolant leaks as well also the system operates to pull the de F out of the lines when the truck shuts down if you hear a pump running after you turn off the key that’s normal other than your attention to the de F level you won’t find operating an EPA 10 truck to be different than operating other trucks in fact it’ll be easier than running an O 7 emissions vehicle because you are not likely to be bothered by any DPF regeneration requests or indications one indication you may see from time to time is the high exhaust system temperature or hessed lap this is part of normal operation it’s usually a result of the control system developing some extra heat in the exhaust to warm up the scr catalyst or regenerate the filter in the D p.m. to review remember don’t mess with the death pay attention to the de F gauge and indicator lights fill with de F when needed keep all de F related containers caps and dispensers clean know where to check for leaks during the pre trip and realize that the hessed lamp may come on from time to time as part of the normal operation of the vehicle do these things and when someone asks if you like driving a 2010 Mac you’ll be saying most definitely

you you so you’re driving this Mac tariff row with 2010 emissions what do you need to do to get this truck through a day’s work without having a problem on the road here are the basics as compared to previous Mack trucks the main differences you’ll notice are the scr catalyst and the de f tank if you haven’t been in a Mac with any exhaust after treatment before you may also be unfamiliar with the DPF or diesel particulate filter the DPF filters out the fine particulates in diesel exhaust the particulates this unit collects need to be burned off in a process called regeneration or reject this keeps the filter clean enough to continue filtering properly normally this activity doesn’t involve you but in what will be extremely rare instances you might be called upon to initiate a region if so on 2010 Terra pro models you’ll see two indicators the initiate indicator on the dash and the DPF switch light pull over at the next convenient stop set the parking brake and press the top of the switch then let the vehicle complete the park region this should take about 30 minutes you’ll notice the engine idle speed elevated between 1000 to 1200 RPM range during this time once complete you can be on your way if you see the initiate indicators flashing it’s time to pull over immediately and initiate the regen and by the way for twenty ten vehicles these switches may come with or without a regen inhibit function for the lower part of this switch if it does include inhibit the function will either inhibit all regions for a period of time or until the next key cycle or it will lock in the inhibit to prevent regen for as long as the switch is pressed in at the bottom even after a key cycle when the inhibit is locked in you’ll probably find the vehicle speed limited you’ve got an indicator on the dash now to tell you when the DPF inhibit function is active so if inhibiting is not what you really want to do put the switch back into the middle position refer to the visor label and the operator’s manual for more detailed information SC R stands for selective catalytic reduction an SCR catalyst is added to the exhaust system to reduce the NOx emissions from the vehicle this is accomplished through adding diesel exhaust fluid or de F to exhaust the resultant chemical reaction changes oxides of nitrogen into harmless water vapor and nitrogen more on that in a moment you don’t have to worry much about the SCR catalyst as long as you don’t plug it up by doing the wrong thing with the de F will cover the mistakes to avoid with de F a bit later for now just remember that this catalyst will get hot in operation and will stay hot for quite a while after the engine stops avoid touching the de F tank is easy to find it’s got the blue cap by the way de F is also called death de F is needed to work with the SCR catalyst to reduce NOx it is sprayed into the exhaust stream through an injector after the DPF and before the SCR catalyst de F is a refined chemical product that contains 68% purified water and 32 percent urea urea is an organic compound and is used in many ways in industry and agriculture de F does not contain any

diesel fuel and is not a diesel fuel additive never under any circumstances or anything other than de F from approved dispensers into this tank also de F only goes into this tank never in the diesel tank so if there is one important thing to remember about these trucks its don’t mess with the death you’ll find a gauge in the truck to show the de F level if you don’t want to experience any engine D rates or vehicle speed limitations you can’t let this tank get low you certainly don’t want it empty if you start seeing indications like this you’re going to have problems this indicator is the symbol for de F if it is solidly lit then begins flashing your truck is going into de-rate more importantly if you fill with diesel and forget to fill a critically low de F tank your truck is only going to go 5 miles per hour yes that is 5 miles per hour until you put some de F in that tank for reference consult this visor later it will tell you what the de F indications mean bottom line pay attention to the gauge while driving and fill the tank when needed expect to refill the de F about every other fuel tank if you are just starting out check the gauge and the dash to see if the de F indicator is lit if flow or the indicator is on or both fill the de F tank if the indicator goes out drive the truck if it stays on the truck requires service when filling use only certified de F from an approved dispenser or a sealed container again don’t even think about putting anything else in the tank no straight water no diesel oil gas any type of petroleum product no homemade farm made or chemistry teacher made mixes and no recycled human or animal liquid wastes no cleaners solvents or soaps just approved de F in addition don’t use containers funnels pumps or dispensers that were previously used to handle any other liquids oils fuels coolants cleaners or solvents to store or dispense de F keep the de F handling items specific to de F and de f only using anything other than pure certified de F from an approved manufacturer means that you will shorten the life of the SCR catalyst you might clog or poison it so that it doesn’t work remember any petroleum products cleaners and solvents will damage the de F pump and lines in addition when filling keep everything clean clean clean wipe off the cap area if needed and make sure the container or nozzle is clean no dirt paper or cloth fibers or foreign particles of any kind should be allowed in the tank bottom line don’t introduce anything into the de F tank that is not de F how can you be sure you’re getting the right stuff look for this symbol on the label or on the dispenser and just in case you might beware de F isn’t it’s not a bad idea to carry an extra container in the truck with you by the way the size of the fill hold and the de F tank won’t accept the dispenser nozzle for diesel or gas it’s too small de F isn’t harmful or even considered a hazardous material handle it the same way as you would household ammonia avoid skin or eye contact don’t drink this stuff and avoid breathing the fumes directly or in an enclosed area if some does get on you you flush the area with large quantities of water and wash with soap you should be aware of the various locations where de F is flowing on the vehicle all hoses and connection points should be inspected for leakage during a pre-trip inspection when it dries de F leaves a white powdery residue so it’s not just liquid coming out that you should check for here are the areas to check at the connections to the SCR pump

assembly at the de F injector in the exhaust at the exhaust clamps between the DPF and the SCR catalyst because de F can freeze at about 12 degrees Fahrenheit or colder the hoses to the injector are electrically heated the tank and the injector are also heated or in the injectors case cooled by engine coolant look for coolant leaks as well when the truck shuts down the system operates to pull the de F out of the lines it’s normal to hear a pump running after you turn off the key aside from careful attention to the de f level gauge you won’t find operating an EPA ten tariff Pro to be very different from operating other models in fact it will be easier than running an O seven emissions vehicle because you are not likely to be bothered by many DPF regeneration requests or indications one indication you may see from time to time though is the high exhaust system temperature or test lamp this is part of normal operation normally it’s a result of the control system developing some extra heat in the exhaust to warm up the scr catalyst or regenerate the filter in the DPF when driving your EPA 10 tara pro remember don’t mess with the death pay attention to the de f gauge and indicator lights filled with de F when needed about every other fuel fill-up keep all de F related containers caps and dispensers clean know where to check for leaks during the pre trip and realize that the hessed lamp may come on from time to time as part of the normal operation of the vehicle do those things and when someone asks if you like driving a 2010 Mack Terra Pro you’ll be saying most definitely you you
