HOW TO START A GLOWPLUG MODEL ENGINE

WARNING
o Please read and follow these safety instructions and warnings before attempting to operate an engine.
o Get training from an experienced modeler before you operate your model.
o Don't allow loose objects near the prop, don't run the engine in an area of loose gravel or sand.
o Never run your engine in an enclosed place.
o Keep your fuel in a safe place away from naked flame and in a cool, dry area.

Pre Start Instructions

Install the engine and mount the fuel tank closely behind it at approximately carb height or slightly below, fix the propeller firmly to the engine. The propeller should be located on the shaft so that its blades are approximately in the "twenty to two" position with the piston at the top of its stroke. NOTE: If the engine feels "tight" when rotated thru TDC…..DON'T PANIC!!! It's quite normal for a good ABC (A luminium piston, B rass liner, C hromed bore) engine to exhibit this feature as the bore has a slight taper at Top Dead Centre.

Secure the muffler to the engine with the screws provided, and be sure to tighten them firmly.
The muffler is provided with a pressure nipple. Connect this to the vent line on your fuel tank, and the slight positive pressure helps keep a constant fuel head to the engine.

Connect the glow plug to a 1.2 - 1.5 volt battery, or adjust the Power Panel voltage to ensure a bright red or orange glow at the plug element. Screw the glow plug into the cylinder head and tighten it with a light nip.……….DO NOT OVER TIGHTEN!

Take off the fuel line from the needle valve and the pressure fitting on the muffler. Fill the tank thru the needle valve line until it overflows from the vent. Connect the fuel and vent lines once more and close the needle valve all the way by turning clockwise, then open it 2 to 2.5 full turns.

Put your finger over the carburetor intake, turn the propeller to draw fuel from the tank and fill the fuel line then connect the glow plug clip, close the throttle all the way, then open it about one third.

Flip the propeller quickly in a counter-clockwise direction until the engine starts or use a 12 volt starter (makes starting instant). When the engine runs steadily, remove the glow plug clip.

IF ENGINE FAILS TO START:

CHECK
1. Glow Plug,
2. Dirt in Needle valve,
3. Fresh Fuel and if all else fails CALL US! 06 3555 747

ADJUSTING THE NEEDLE VALVE

1. Start the engine.
2. Open the throttle to full, and remove the glow plug clip.
3. If the engine is making a "burbling" sound screw in the needle valve slowly, which leans the fuel mixture, if the engine cuts dead then the mixture is to lean and the needle needs to be screwed out.
4. Once full throttle has been established back the main needle out about 2-3 clicks rich.
5. Set the throttle to idle (the barrel should be slightly open) and ensure a smooth idle (2000-2500RPM)
6. Advance the throttle to full and ensure the engine accelerates cleanly, a spluttery acceleration indicates the mid range mixture needs leaning up and this is done by screwing the small recessed screw in the centre of the throttle arm in a ¼ of a turn at a time until the engine accelerates smoothly, a dead cut means the mixture is over lean and the screw should be rotated slightly anti clockwise until the engine runs smoothly.
7. At full throttle point the nose of the model straight up and listen to the engine, if it slows down, open the needle valve one more click. Repeat until engine does not slow down when the nose is pointed up.
8. On a new engine the idle and transition may take a few tanks to settle down as the engine runs in.

TO STOP THE ENGINE

1. Close the throttle completely by using the trim function on the throttle stick. With the trim full forward the engine should have a fast idle, mid trim normal idle, and trim right down a dead cut. (Ensure the barrel in the carb is allowed to close right off without loading the servo, use EPA end point adjustment on the Tx to set)
2. If this doesn't stop the engine, pinch the fuel line.
3. Do not throw a rag or anything into a running engine to stop it.

NECESSARY ACCESSORIES TO RUN THE ENGINE

(a) FUEL
Please use a good quality commercial fuel containing 5-10% nitro and 18-20% synthetic oil (CoolPower is excellent!) Galtech can supply pre-mixed or components to mix your own.

(b) GLOW PLUG
The type of glow plug used can have a considerable effect on performance and reliability. We recommend by our own experience that an OS #8 is a good starting point. Some of the Chinese engines benefit from a Hot plug (OS#1 or McCoy)

(c) PROPELLER
As the ideal propeller diameter and pitch can vary according to the engine capacity plus size, weight and
type of model, final propeller selection can only be made after practical experiment. For example on a .46 size trainer a Master 10x6 or 7 or 11 x 4 is fine. In comparison on the same motor in an aerobatic, performance model like our "Sukhoi" we run a Bolly or APC 12.6 x 3.6 which gives stunning performance.

(d) STARTING BATTERY
The power source used to start the engine may be a 1.2 volt ni-starter, 1.5 volt heavy duty dry battery, or a
power panel connected to a 12 volt source.

(e) 4-WAY WRENCH
This is needed to install and tighten glow plug and propeller.

(f) GLOW PLUG CLIP
Needed to get the power from the battery to the glow plug. (unless using a ni-starter where this is built in)

(g) FUEL TANK
Purchase the proper one to fit your model, the standard type .46 engine will run around 10-12 minutes on a 10 ozs tank.

(h) FUEL PUMP
Needed to get fuel from your can into fuel tank. Both 12 volt electric and hand operated types are
available.

(i) SILICONE FUEL LINE
Needed to connect the fuel tank to the carburetor and the fuel tank to the pressure fitting on the muffler.

(j) CHICKEN STICK
Used instead of your finger to flip the propeller for starting the engine. (can be as simple as a screw driver handle or piece of 25mm wood dowel)
