Set Up Checklist• Lubricate the locomotive• Prime the smoke unit• Check to see whether the battery needs to be charged for full sound effects• Apply power to run as described in the Basic Operating Section of this manualLubricationYou should lubricate the engine to prevent it from squeaking. Uselight household oil and follow the lubrication points marked “L” inFig. 1. Do not over-oil. Use only a drop or two on each pivot point.DO NOTOVER OILLubricate Pick Up Rollers (L)Lubricate Wheel Axles (L)Figure 1. Lubrication Points on the LocomotivePriming The Smoke UnitWhen preparing to run this engine, add 15-20 drops of smoke fluid through thesmokestack (see Fig. 2). We recommend M.T.H. ProtoSmoke, Seuthe, LGB, or LVTSfluids. Do not overfill the unit or the fluid may leak out and coat the interior enginecomponents.If you choose not to add the fluid (or have already added the fluid but choose to runsmoke-free), turn off the smoke unit switch located under the engine (see Fig. 3).Failure either to add fluid to the unit or to turn it off may damage the smoke unitheating element and/or wicking material.Premier SD40-2 Diesel Engine 3

If younotice that the sounds are garbled, test and charge the engine as described in the"Self-Charging Battery Back-Up" on page 15.4 Premier SD40-2 Diesel Engine

Basic OperationThe Throttle knob controls how fast your train will travel.Turn the throttle knob up ½-way, until the engine and caboose lights shine bright.Put the engine into motion by pressing the Direction button on your transformer once.(hold it for approximately 1 second)If the engine does not begin to move as soon as you firmly press the Direction button,you may not have sent enough voltage to the track to make the train move. Turn thethrottle up a bit higher until the train begins to move.Activating FeaturesThrottle To increase or decrease track voltage, and therefore train speed, turn thethrottle control knob. Turning clockwise will increase voltage and speed, while turningcounterclockwise will decrease voltage and speed. The engine will maintain the speedyou set after you release the throttle until you turn it again to change the voltage andspeed.Bell - To sound the bell, in an engine equipped with a bell firmly press and release theBell button. To turn the bell off, press and release the Bell button again. The bell willcontinue to ring from the time you turn it on until you press and release the button againto turn it off.Horn/Whistle - To sound the whistle, firmly press the Horn/Whistle button. The whistlewill sound for as long as you continue to depress the button. It will stop when yourelease the button.Direction Your train is programmed tostart in neutral. The train will alwayscycle neutral-forward-neutral-reverse witheach press and release of the directionbutton. The engine is programmed torestart in neutral each time the trackvoltage is turned off for 25 seconds ormore.Cycle PhasesNeutralReverseNeutralForwardPremier SD40-2 Diesel Engine 5

Manual Volume ControlTo adjust the volume of all sounds made by this engine, turn the master volume controlknob located next to the fuel tank clockwise to increase the volume andcounter-clockwise to decrease the volume.Proto-Sound 2.0Volume Adjustment KnobFigure 4: Manual Volume Adjustment Knob6 Premier SD40-2 Diesel Engine

Tips on Using FYS• You can terminate FYS at any time by turning off power to the track for 15seconds.• You do not have to be in Forward to use FYS. At the conclusion of the fullsequence, the train will pull away from the station in whatever direction youwere going when you activated the feature.• You can use FYS even if you are double-heading with another engine. If thesecond engine is not equipped with Proto-Sound 2.0, you must remembernot to leave the throttle at a high voltage level once you have stopped theengine to run the FYS. Otherwise, the engine without FYS will beginvibrating on the track as its motors strain to move the train, since theycannot be automatically disabled during the FYS cycle (or if an originalProto-Sound engine, FYS are triggered differently and that engine'smotor-disable feature will not be active when you run FYS in Proto-Sound2.0).• FYS can be triggered from Neutral. It will operate the same as if triggeredwhile in motion except that, at the conclusion of the FYS, the engine willdepart in the next direction of travel, as opposed to the direction it wastraveling before entering Neutral.Proto-Coupler® OperationThis locomotive is equipped with one or more coil-wound Proto-Couplers for remoteuncoupling action. Because Proto-Couplers are controlled through the Proto-Sound 2.0microprocessor, they do not require an uncoupling track section or modification to yourlayout to function. You can fire a coupler from neutral or while in motion. Use the codeshown below (and in the chart on p. 7) to fire the coupler(s).Rear Coupler:To fire the rear coupler, quickly tap the Bell button once followed by three quick taps ofthe Horn button, allowing approximately ½ second to lapse between each quick buttonpress. The sound of the liftbar and air line depletion will play, and the knuckle will bereleased.BellHornHornHornFireRear = CouplerPremier SD40-2 Diesel Engine 9

Front Coupler:To fire the front coupler (if your engine has one), quickly tap the Bell button oncefollowed by four quick taps of the Horn button, allowing approximately ½ second tolapse between each quick button press. The sound of the liftbar and air line depletionwill play, and the knuckle will be released.BellHornHornHornHornFireFront = CouplerSpeed ControlM.T.H. engines equipped with Proto-Sound 2.0 have speed control capabilities that allowthe engine to maintain a constant speed up and down grades and around curves, muchlike an automobile cruise control. You can add or drop cars on the run, and the enginewill maintain the speed you set.While the engine is programmed to start with the speed control feature activated, you canopt to turn it off. This means the engine's speed will fall as it labors up a hill and increaseas it travels downward. It is also affected by the addition or releasing of cars while on therun. Because the engine will run more slowly at a given throttle voltage when speedcontrol is on than when it is off, you should adjust the throttle to a lower power level foroperation with speed control off to avoid high-speed derailments. When speed control isoff, the volume will drop to allow for better low voltage operation.To turn speed control on and off, put the engine in neutral, then quickly tap thetransformer's Horn button one time then quickly tap the Bell button two times, allowingapproximately ½ second to lapse between each quick button press. Two horn blasts willindicate that the engine has made the change. Repeat the 1 horn, 2 bells code to return itto the other condition. You will want to do this during the initial neutral upon start-up ifyou ever couple this engine to another engine that is not equipped with speed control toavoid damaging the motors in either engine. Each time you shut down the enginecompletely, it will automatically turn speed control on.PlaceEngine intoNeutralHornBell Bell =Speed ControlTwo Horn Blasts(indicates change is made)Repeat to Returnto Normal Condition10 Premier SD40-2 Diesel Engine

Locking Locomotive Into A DirectionYou can lock your engine into a direction (forward, neutral, or reverse) so that it will notchange directions. To do this, put the engine into the direction you want (or into neutralto lock it into neutral), run it at a very slow crawl (as slowly as it will move withouthalting), and quickly but firmly tap the Horn button once followed by three quick taps ofthe Bell button, allowing approximately ½ second to lapse between each quick buttonpress. Two horn blasts will indicate that the engine has made the change. The engine willnot change direction (including going into neutral) until you repeat the 1 horn, 3 bellscode to return the engine to its normal condition, even if the engine is kept without powerfor extended periods of time.PlaceEngine intoDesired HornDirectionHorn Bell Bell Bell =Direction LockTwo Horn Blasts(indicates change is made)Repeat to Returnto Normal ConditionReset To Factory DefaultTo override the settings you currently have assigned to the engine and reset it to itsfactory defaults, while in Neutral tap the Horn button quickly once, followed by fivequick taps of the Bell button, allowing approximately ½ second to lapse between eachquick button press.

MaintenanceLubricating and Greasing InstructionsThe engine should be well oiled and greased in order to run properly.Regularly lubricate all axles and linkage components and pickup rollers to preventsqueaking. Use light household oil, such as that found in M.T.H.'smaintenance kit. Do not over oil. Use only a drop or two on eachpivot point.DO NOTOVER OILBody Mount ScrewsFigure 5: Body Removal Screw LocationsMotor Mounting ScrewThe locomotive’s internal gearing was greased at the factory and should not needadditional grease until after 50 hours of operation or one year, whichever comes first.Follow the greasing instructions below. Note that in some tightly packed engines youmay need to move internal components temporarily in order to access the gears.1. To access the gear box, remove the cab from the chassis by unscrewing the chassisscrews as seen in Figure 5 and lifting the cab from the chassis.2. Once the cab is removed, remove the trucks by unscrewing the black Phillips motormount screw located on the underside of the drive trucks (see Fig. 5).3. Once the motor mount screw has been removed, pull the motor away from the truckblock and lightly coat the motor worm gear and bronze drive gear (in the truck block)with grease.4. Reassemble the truck and motor, being careful not to pinch any wires between thetruck block and motor mount.12 Premier SD40-2 Diesel Engine

5. After repeating the procedure for the other motor, reassmble the chassis and body,being careful that the wire harnesses are not caught between the chassis and body andreinstall the chassis screws.Lubricate the outside truck blockidler and drive gears with grease.Use the diagram shown in Figure 6below as a guide and add grease tothe points marked with a “G.”Grease Idler Gears (G)Figure 6: Greasing The Idler GearsCleaning The Wheels, Tires and TrackPeriodically check the locomotivewheels and pickups for dirt andbuildup, which can cause poorelectrical contact and traction andprematurely wear out the neoprenetraction tires. Wheels and tires can becleaned using denatured (not rubbing)alcohol applied with a cotton swab.To clean the track, use RailKing TrackCleaning Fluid and a clean rag ordenatured (not rubbing) alcohol.Unplug the transformer and wipe therails of the track, turning the ragfrequently to ensure that you are usingclean cloth on the rails. Thereafter,keep an eye on the track and clean itwhen it gets dirty to ensure good electrical contact and to lengthen the life of the tires.Premier SD40-2 Diesel Engine 13

Traction Tire Replacement InstructionsYour locomotive is equipped with two neoprene rubber traction tires on each poweredtruck block. While these tires are extremely durable, you may need to replace them atsome point.First, remove the trucks from the chassis by unscrewing the body mounting screws asnoted in Figure 5. Next, remove the trucks from the chassis by unscrewing the truckmounting screw also noted in Figure 5. Finally, turn the removed truck over and locateand remove the truckside screws to gain access to the drive wheel traction tires behindthe trucksides.Once the truck sides have been removed:1. Make sure the old tire has been completely removed from the groove in the drivewheel, using a razor blade or small flathead screwdriver to pry away any remains.2. Slip the new tire onto the wheel. You may find it useful to use two small flatheadscrewdrivers to stretch the tire over the wheel.3. If you twist the tire while stretching it over the wheel, you will need to remove andreinstall the tire. Otherwise your engine will wobble while operating.4. Make sure the tire is fully seated inside the groove. Use a razor blade to trim away anyexcess tire that will not seat inside the groove properly.5. Reassemble in the reverse order.One set of replacement tires is packaged with your model. Additional sets are availabledirectly from the M.T.H. Parts Department (order online: www.mth-railking.com,e-mail: parts@mth-railking.com; mail: 7020 Columbia Gateway Drive, Columbia MD21046-1532, FAX: 410-381-6122).14 Premier SD40-2 Diesel Engine

Headlight Replacement InstructionsThe locomotive’s headlight is controlled by a constant voltage circuit in the engine. Theheadlight is easy to remove and replace when it burns out. The bulb has a quickdisconnect plug that attaches the bulb harness to a connector terminal inside the bodyshell. Replacement bulbs are available directly from the M.T.H. Parts Department.Follow the body removal instructions found in the Lubrication and Greasing Instructions.Replaceable LightsFigure 7: Removing The Replaceable LightsGently disconnect the bulb harness from the socket on the constant voltage circuit orconnector terminal and replace the bulb.Self Charging Battery Back-UpThe special NiCad 7-cell 8.4v self-charging battery recharges continuously during trainoperation and should last for up to five years. The battery is a dry battery that should notleak or cause any damage to your engine. Depending upon when your engine was built,it may need to be charged right out of the box. If engine sounds seem distorted orgarbled at low voltages or become silent when power from the transformer is turned off,test the battery to determine whether it should be recharged or replaced.Test: Put the engine in neutral and leave the track voltage at 10-12 volts (high enoughfor the lights to shine brightly and the engine to move steadily) for 15 minutes.Premier SD40-2 Diesel Engine 15

Recharge: If the sounds are improved at the end of the 15-minute test charge, the batterycharge has run down and can be recharged. There are a number of ways you can do this:• Leave the engine in neutral with track voltage at 10-12 volts for 6-7 hours so thebattery can fully recharge(if your engine has aBattery Charger Portsmoke unit, be sure it isturned off).• Use M.T.H.'s batteryrecharger (sold separately)that plugs into a wall outletand a special port under theengine to recharge thebattery overnight withoutleaving it on the track.Figure 8: Battery Charger PortReplace: If the sounds are notimproved at the end of the 15-minute test charge, it is time to replace the battery.Disconnect Battery,And Slide Out Battery In Direction Of ArrowFigure 9: Removing The BatteryProtoSmoke® Unit OperationThis Premier diesel locomotivecontains a Proto-Sound 2.0 controlledsmoke unit that outputs smokethrough the smokestack on the roofof the engine. The smoke unit isessentially a small heating elementand wick that soaks up and then heatsa mineral oil-based fluid that emits aFigure 10: Adding Smoke FluidAdd Smoke Fluid16 Premier SD40-2 Diesel Engine

harmless smoke. The smoke is then forced out of the stack by a small electric fan.Smoke volume is controlled by the Proto-Sound 2.0 system.With a few easy maintenance steps, you should enjoy trouble-free smoke unit operationfor years.When preparing to run this engine, add 15-20 drops of smoke fluid through thesmokestack (see Fig. 10). We recommend M.T.H. ProtoSmoke, Seuthe, LGB, or LVTSfluids. Do not overfill the unit or the fluid may leak out and coat the interior enginecomponents.If you choose not to add the fluid (or have already added the fluid but choose to runsmoke-free), turn off the smoke unit switch located under the engine. Failure either toadd fluid to the unit or to turn it off may damage the smoke unit heating element and/orwicking material.When the smoke output while running the engine begins to diminish, add another 10-15drops of smoke fluid or turn the smoke unit off.When storing the unit for long periods of time, you may want to add about 15 drops offluid to prevent the wick from drying out.After removing the engine from storage, add another 25 drops of fluid, letting the wicksoak up the fluid for 15 minutes prior to operation.If you experience poor or no smokeoutput when the smoke unit is on andhas fluid, check the wick to see if it hasbecome hard, blackened, andunabsorbent around the heating element.After removing the locomotive bodyfrom its chassis (See Figure 5), removethe smoke unit inspection cover (seeFig. 11). After removing the inspectioncover screws, lift the inspection plateaway and inspect the wick. If it isdarkly discolored and hard, it should bereplaced.Figure 11 : Smoke Unit InspectionInspection CoverScrewsReplacement parts and wickreplacement instructions are available directly from the M.T.H.

Do NOTuse oil.The coupler needs to be cleaned.Wipe with denatured alcohol (notrubbing alcohol) and let dry.18 Premier SD40-2 Diesel Engine

Cab ChatterSometimes the Cab Chatter soundsdon’t play.Lock-outI can’t get the engine to run after Ipower up the transformer. It sits stillwith the engine sounds running.The engine won’t lock into forward,neutral, or reverse.VolumeThe sounds seem distorted, especiallywhen the whistle or bell is activated.RemedyCab Chatter plays only in neutral atrandom intervals.RemedyThe engine is locked into the neutralposition. Follow the procedure in the“Lock into a Direction” section.Engine speed must be below 10 scalemph (approx. 10 volts or less inconventional mode).RemedyProto-Sound 2.0 volume is set toohigh. Turn the volume control knob onthe bottom of the chassis counterclockwiseto reduce the volume.BatteryThe engine will not leave the initialneutral setting.I get no sounds when the engine shiftsbetween directions.RemedyCheck to be sure the battery isinstalled and fully charged. See the“Self-Charging Battery Back-Up”section.The battery may be dead or need tobe charged. See the “Self-ChargingBattery Back-Up” section.After I turn off my transformer, myengine continues to make soundsbefore quitting.FYSThe FYS sounds occasionally repeatthemselves.Proto-Sound 2.0 is designed tocontinue to sound for a few secondsafter power to the track has been shutoff.RemedyProto-Sound 2.0 has a built-in randomnumber generator that randomlyselects each sound clip to play.Because there are a limited number ofsound clips available in each FYSsequence, it is probable that some ofthese sound clips will be repeatedfrom time to time.Premier SD40-2 Diesel Engine 19

FYSOnce in FYS, the engine doesn’t gointo reverse.When the FYS enters its lastsequence the bell automaticallycomes on.When FYS is enabled, pressing thewhistle and bell buttons has no effect.RemedySo that FYS effects can be as realisticas possible, Proto-Sound 2.0disables the reversing unitwhenever FYS is enabled. Thisway the engine remains still at itsstop as the operator cyclesthrough the FYS sequences.FYS is programmed to startringing the bell at that point. Afterapproximately 12 rings of the bell,it will automatically turn off.Because FYS must control variouseffects in each sequence, Proto-Sound 2.0 takes control of thesesound effects until you exit FYS.I push the direction button but the nextsound clip in the sequence does notplay or the engine does not come outof FYS after fourth press of thedirection button.Each FYS clip must play for approx.30 seconds before FYS will advanceto the next step in the FYS cycle.Wait at least 30 seconds in each FYSsound clip before pressing thedirection button.20 Premier SD40-2 Diesel Engine

Transformer Compatibility and Wiring ChartProto-Sound 2.0 is designed to work with most standard AC transformers. The chartbelow lists the many compatible transformers. Note that many of the operationalcommands described in these instructions require a bell button, so if your transformerdoes not have its own bell button, you should consider adding one to get the full benefitof the system.
