Operation
Slide 10: Pre Trip Inspection
Pre Trip Inspection Before Starting ▪ Check fluid levels – Oil, Coolant – Level surface, wait 15 minutes for oil to drain to pan – Never remove radiator cap if coolant is hot (>120 degrees) ▪ Air Intake – Check Restriction indicator After Starting – walk around coach ▪ Check gage levels (DEF, fuel,
Slide 11: Operation – Dash Lamps
Operation – Dash Lamps HEST (High Exhaust System Temperature) lamp Elevated exhaust temperature. Don’t drive over leaf pile. DPF (Diesel Particulate Filter) lamp – soot is present in exhaust filter. Increase system temperature by doing a highway drive for 30-40 minutes. Check Engine Lamp – check flu
Slide 12: Do you speak engine?
Do you speak engine? ▪ Cummins Guidanz – 2007 and newer – Read your check engine light from your smart phone – App is free ▪ Inline Mini adapter (part number 5299909) – Bluetooth datalink adapter – Plugs under dash near steering wheel – Can move from vehicle to vehicle ▪ Process – If CEL comes on, p
Slide 13: Operation: What is Regeneration?
Operation: What is Regeneration? ▪ Soot accumulates in the DPF ▪ Without regeneration, DPF can plug ▪ We oxidize the soot by regeneration – Passive – any time exhaust system is hot – Active – extra fuel creates extra heat ▪ All that is left is ash (minerals) Similar to how your self cleaning oven wo
Slide 14: Fuel Economy
Fuel Economy ▪ What consumes horsepower? – Aerodynamics (>50 mph) • Air drag is a function of speed (10 mph = 1 mpg) • Customer control – slow down – Rolling Resistance (<50 mph) • Function of weight, road surface, tires, tire pressure • Customer control – proper inflation and tire selection – Acces
Slide 15: Engine braking
Engine braking ▪ Two types of auxiliary braking – VGT Exhaust brake – restricts exhaust • Switch ON/OFF on dash (B6.7/L9) – Compression brake – releases compression • Switch ON/OFF and SwitchHI/LOW or HI/MED/LOW (L9/X12/X15) ▪ Benefits – Better vehicle control – Eliminates brake fade downhill – Serv
Slide 16: Compression brake usage
6 Compression brake usage – Maximum braking at higher engines speeds – this is why the transmission downshifts – Allison will not force a downshift that will overspeed – Do not use during icy or slick road conditions – Okay to leave switch in on position – Won’t engage unless accelerator pedal is at
Slide 17: Other operating tips
Other operating tips ▪ Warm-up – operate with light throttle until coolant temperature reaches 150 degrees ▪ Cooldown – light load – idle for 3-5 minutes ▪ Monthly engine exercise – You are exercising the generator monthly, why not the engine? – Good – run engine at high idle (use the cruise set swi

Motorhome Maintenance Intervals B6.7 C8.3/L9 ISX12 ISX15/X15 (200-360hp) (330-450hp) (500hp) (550-605hp) Coolant testing 6 months 6 months 6 months 6 months Oil and oil filter* 12-18 months 12-18 months 6 months 12 months 15,000 miles 20,000 miles 25,000 miles 30,000 miles Fuel filter* 12-18 months
Slide 20: Air System
Air System ▪ The most expensive mistake you can make – Only takes a teaspoon of dust to create major damage – Dirt can damage turbo, cylinder head, power cylinders ▪ Maintenance – Follow chassis manufacturer recommendation (12-24 mos) – Check restriction indicator when fueling – Pay attention when i
Slide 21: Fluids – Fuel
Fluids – Fuel ▪ Buy from high volume location (truck stop) ▪ Cummins does NOT require fuel additives – Two special cases where fuel additives can be useful: • Black “slime” in fuel filter – Biocide and fuel filters • Cold weather operation – Fuel can gel at temperatures below 15 degrees – PowerServi
Slide 22: Fluids – Oil
Fluids – Oil ▪ Use a name brand oil ▪ API Classification – Preferred: CK-4 (don’t use FA-4) – Pre2021 – 15w40 – 2021 and later – 10w30; 15w40 acceptable ▪ Synthetic Oils – More expensive than mineral based oils – Do NOT extend oil drain intervals – Main benefit – very low temperatures (-13 deg F) or
Slide 23: Fluids – Coolant
Fluids – Coolant ▪ Coolant has many jobs – Protect against corrosion and liner pitting – Cool engine and transmission, lubricate seals ▪ Know what coolant you have – Top off only with the same brand – Tell your service provider what coolant you want ▪ Test – 2x per year for freeze point (CC2806) – A
Slide 24: Fluids - DEF
Fluids - DEF ▪ Freezes at 11°F (does not degrade) ▪ ISO spec 22241-1 – 32% Urea, 68% deionized water ▪ Shelf life 1 – 2 years depending on temperature – Avoid direct sunlight and temperature above 78°F ▪ Non-toxic, non-polluting, non-flammable ▪ 2-6 gallons DEF for 100 gallons of diesel – Most motor
Slide 25: DEF Lamp Sequence
DEF Lamp Sequence or ▪ Just like your car – There is a DEF level gage on dash, a gage on tank, and warning lamps – Lamp comes on if you don’t pay attention to gage ▪ Lamp sequence 1. Solid 2. DEF Solid 3. DEF Blinking 4. DEF Blinking, CEL Solid CEL Solid CEL Solid and Stop Engine ▪ If you ignore the
Slide 26: Long term storage (6 months) suggestions
Long term storage (6 months) suggestions ▪ Better to change oil/filters before storage than after ▪ Fill fuel tank (prevent condensation) ▪ Don’t store with Biodiesel or use the exercise program ▪ A monthly exercise program is good – Operating temperature, lubricate parts, charge batteries ▪ Tighten
