1. Coal fired steam locomotive NGG16 Garratt Owners Manual Contents Controls Locomotive running tools Running in Preparing to run your locomotive Running your locomotive Once you have finished your running session Maintenance troubleshooting Precautionary instructions The NGG16 Garratt locomotive operates just like its full sized counterpart by using coal to produce steam under pressure Therefore parts of the locomotive will become very hot Provided the locomotive is operated with adequate care and attention no problems should arise The model is intended for outdoor use and should only be used in well ventilated areas The model is unsuitable for children unless they are carefully supervised at all times The locomotive is not a toy Whilst the locomotive is in steam an exhaust will be emitted through the chimney that includes hot steam ash and sparks Therefore any operator or bystander must not lean over the locomotive while it is running Controls Ii 1 Water gauge glass 2 Water gauge glass blow down valve 3 Pressure gauge 4 Lubricator 5 Blower valve 6 Water bypass control Locomotive running tools The following tools are supplied with your new locomotive Battery blower Firing shovel and pricker Flu brush Water top up bottle Bottle of steam oil Bag of coal Preparing your locomotive Your locomotive must be fully prepared before every running session in accordance with2. locomotive fill the firebox level to the door with unlit paraffin soaked charcoal Your locomotive is now ready to be steamed Operating your locomotive Raising steam When you are ready to light your locomotive place the battery blower into the chimney and turn it on Then prepare a shovel of lit paraffin soaked charcoal and shovel this into the firebox to light the fire Soon after shovel three or four more loads onto the fire and shut the firebox door After a couple of minutes or so put another three or four loads into the firebox as to create a nice even spread and again shut the door It is important to keep the firebox door shut as much as possible as the most heat is lost here because the electric blower is pulling cold air across the fire Keep an eye on your fire and if it looks to be fading add some more charcoal With practice you will gain a working knowledge of how your locomotive s fire behaves during the warming up period You will soon have steam pressure and once the pressure gauge reaches 40psi pounds per square inch or above you can then open the locomotive s own steam blower and remove the battery blower from the chimney at the same time The locomotive will now be able to draw its fire harder and therefore generate more heat from the charcoal You will be able to see the fire increase in intensity and hear the increased draw from the locomotive s steam blower if you can t open the blower a little m
3. the operational guidelines below Use light motion oil to lubricate the valve gear Make sure to include all moving parts The water axle pump ram located just above the front axle together with its joint to the eccentric arm are both easy to miss yet require routine lubrication Also there are parts of the eccentric located on the rear axle that will benefit from frequent lubrication Remove the front tank to access the axle pump It is recommended that this is done first before the tank is filled with water Fill the boiler with water using the top up bottle or if the boiler is completely empty remove a safety valve and fill the boiler Distilled water is preferred if available Place the end of the flexible pipe from the bottle into the water top up valve which is located under the dome Fill until the water reading is slightly over the top of the gauge glass Next fill up the front tank with water To do this remove the tank cap located in the middle of the tank N B If distilled water is not available clean soft tap water filtered rainwater or filtered water from a dehumidifier may also be used Next unscrew the top of the lubricator and also unscrew the drain of the lubricator Allow any water to drain then as oil starts to appear retighten the lubricator drain screw finger tighten only Top up the lubricator with steam oil until full and then screw the top on again finger tight Shortly before you re ready to light the
4. If the water level drops too low i e it falls to the very bottom of the gauge glass attach the top up bottle to the water top up valve in the cab and add water to the boiler using the bottle Operators should aspire to run their locomotive efficiently eventually achieving between 10 15 minutes running time between firings while remembering to keep the tank topped up with water N B If you intend running your locomotive for extended periods the lubricator will require oil after about an hour please note it will be hot You will also need to keep the water pump ram and its cam between the locomotive frames well oiled Once you have finished your running session Once you have finished running your locomotive it needs to be disposed of responsibly just like the real thing Firstly ensure that the blower valve and regulator are closed and allow the locomotive to cool slightly Next drop the remnants of your fire The NGG16 s ash pan makes this easy Behind the ash pan located under the firebox is a movable hook and bar Just push the hook to one side out away from the bar which is attached to the ash pan the whole ash pan and grate will fall out with guidance and allow complete and easy removal of the remaining fire and ash Beware this may still be hot so please take extreme caution when removing the ash pan Once the fire has been removed and the grate has cooled locate the ashpan back into the firebox with the
5. ing well you must keep all moving parts well oiled It is worth being aware that well oiled valve gear can very easily attract ash onto itself This ash is abrasive and its presence can increase wear on the valve gear To keep this wear at a minimum we suggest using an old toothbrush to remove ash out of the valve gear As is the case for many new locomotives the seals at certain joints may take time to bed in This can soon be overcome by a gentle tightening of the seal If the axle pump is failing to pump enough water into the boiler there are usually two reasons for this The most likely of which is that small particles of dirt have blocked the pump This dirt can be removed by opening the bypass valve in order to allow the water system to unblock itself after amoment of running The second reason for a lack of water is that water may be leaking out of the gland and avoiding the pump Check the gland over the ram is finger tight If you are still having trouble you can disconnect the rubber tube underneath the loco This pipe runs between the centre driving wheels and supplies water to the pump Put the end of your water top up bottle onto the pipe and pump water around the system this pushes out any dirt Once done reconnect the rubber tube and test the locomotive Remember practice makes perfect We hope that you find great enjoyment in your NGG16 Garratt
6. is stationary Shortly before you open the regulator to move the locomotive you may shut the blower valve Once the locomotive is moving the exhaust from the cylinders creates the necessary draft to draw the fire By this stage you will need to add more coal to your fire with the aim of producing a nice deep orange glow Remember to shut the door in between shovelfuls in an attempt to keep in as much heat as possible The water axle pump should be turned on using the bypass valve in the cab Anti clockwise S Clockwise Axle pump is turned Axle pump is turned ON OFF and is not pumping l and is pumping water into Water into the boiler the boiler The bypass valve controls the axle pump which pumps water from the tank into the boiler while the loco is running and therefore maintains a steady level of water in the gauge glass Setting the water bypass valve so it pumps water at the optimum rate is something that is learnt over time as you become familiar with your locomotive If the gauge glass fills completely you will be able to hear the loco prime as the boiler is full of water At this point you should turn off the axle pump by opening the bypass valve This stops water being pumped into the boiler for the moment Only begin to close it again when the gauge glass indicates that the water level has dropped to a more sensible level Keeping plenty of water in boiler is very important and this is why the top up bottle is included
7. ore to increase the air flow through the fire At this stage you can add some steam coal a little at first and again shut the firebox door between each shovelful This allows the coal to start to burn too much at once could choke the fire and put it out You should be aiming for an even spread of coal across the firebox giving an even glow It is recommended that you practice opening and closing the firebox with the fire pricker whilst the engine is cold This will make your shovelling technique more efficient when the locomotive is in steam When the locomotive has reached the full working pressure of 70psi you will be able to move it under its own steam Running the locomotive Turn on the radio transmitter and then the locomotive The switch is located under the rear tank on the right hand side Move the reverser into the desired gear by moving the right hand stick left or right and then open the regulator by moving the left hand stick up Some priming is to be expected identified by water escaping from the chimney This is normal and will soon clear Following priming the locomotive is ready to start running When operating the locomotive it is important to keep a draft to draw the fire Without one the fire will go out When the loco is stationary the blower valve should be open doing this will create the draft of steam required to draw the fire Teach yourself to automatically open the blower whenever the locomotive
8. two locating pins and push the hook back around the bar It is vital that the boilers flue tubes and smokebox are cleared at the end of every run Access to the smokebox door on the NGG16 is gained by lifting the front tank off its locating pins It is strongly recommended that a cloth is draped over the exposed front chassis at this point so that ash cannot get into the valve gear and axle pump On front of the smoke box completely unscrew the centre dart and remove the smoke box door You will probably be able to see an accumulation of ash built up inside the smoke box the amount depends upon the length of your run Next brush out as much of the ash as possible using a small paintbrush A gentle blow down the chimney will remove the remainder Removing the smoke box ash will reveal the boiler tubes Using the flu brush provided clean out the seven tubes that are accessable These can get blocked with bits of coal and ash limiting the boiler s steaming capability Don t worry if it is difficult to push the brush through keep trying dipping the end of the brush in paraffin is helpful Reattach the smoke box door using the screw dart you removed earlier Tighten until finger tight You can now clean your locomotive removing unwanted ash and dirt We have found that a soft paintbrush can be very effective for removing fresh ash that has covered some of the bodywork Maintenance troubleshooting To keep your locomotive runn
