- Page 2 Installing devices * When operating your boiler for the first time, do not connect it initially to the engine. There may be foreign matter in the boiler which could damage the engine. First flush out the boiler for about ten minutes and drain hot water through valve port [B] before the initial operation . (1) Place the boiler, burner, and steam engine on a flat surface. Then fix the boiler and steam engine with wood screws. The burner should be fixed by burner binding plates attached to the surface. Binding plates fixed with (2) Connect each section by rubber tubes and metal pipes referring wood screws to the figure. Slide to insert under the plates Preparation for operation ◆1. Boiler (3) Remove the overflow plug [A] and the safety valve [B]. Fill water through the port of [B] till water comes out from the port of [A]. Placing a towel under [A] is recommended so as not to wet the surrounding area. (4) Then fix [A] and [B] back to their original position by fingers. Do not use wrench or pliers. ◆2. (5) Keep both regulators closed until “Steam up” below is completed. Burner *Use only alcohol (methanol) for fuel. DO NOT use other fuels such as gasoline, paint thinner, petroleum, etc. (6) Close the needle valve[D] using the attached handle. If not closed, alcohol will drain out. ◆2. (7) Remove the red safety valve [C] and fill tank with fuel to 250cc (8.5 oz) using a measuring cup and a funnel. Do not exceed 250cc or the boiler may be damaged if the flame continues to burn after there is no water left in the boiler. (8) Then fix [C] back to the original position by fingers. ◆2. (9) Place the pre-heating tray under the nozzle and fill alcohol to about 50% in the tray using the attached squirter. Steam engine *Carefully read the instruction manual which comes with the T2GR steam engine before operation. (10) Fill the oiler with steam oil (Blue liquid). Lubricate metal, crosshead, crankshaft, eccentric, etc. as well as all revolution and movement sections with machine oil or 50 weight automobile engine ...
- Page 3 Ignition of the burner ◆1. (11) Light the alcohol in the pre-heating tray. Just before the alcohol is consumed, open the needle valve slowly to about 15 degrees for burner ignition.*If not preheated sufficiently, the alcohol will not be vaporized. In such cases, close the needle valve and repeat the process (9) above. *The maximum opening of the needle valve is about 60 degrees Full open Burner needle position approx. 60degs from full close. Adjust to the best position after 10 minutesʼ operation. Full close *Usually itʼ s not necessary to open needles of both nozzles. When 0deg you want greater steam for the engine, opening both needles is required. Steam up *Using the pressure gauge (option) is highly recommended. (12) After the burner is ignited, it takes about 8-12 minutes to raise pressure sufficiently. When the pressure gauge shows 1.0~1.5kgf/cm2, open the regulator quickly to full open position and return to full close position to get rid of remaining air inside the boiler. Then pressure drops immediately and rises gradually again. (13) When the pressure gauge shows 1.0~2.0kgf/cm2, Steam up is completed and now you can operate regulators to run the engine or use the whistle. CAUTION Always keep fuel can, containers, and burnable material away from the burner. And keep a wet ◆1. towel nearby for an emergency. Excessive tightening may greatly shorten the life of packings (O-ring, gasket, or gland packing) ◆2. and even strip or break the threaded part of the needle valve, safety valves, and overflow plug. Always use fixed water and fuel levels for the boiler and burners. ◆3. Do not fill up the boiler with hot water. ◆4. If you restart the engine after stopping the burner forcibly by closing needle valve, there may be ◆5. fuel remaining in the burner. In such cases, the burner can be re-lit immediately while the tank is still hot. But then DO NOT add any fuel. Or after it gets cold, drain the remaining fuel from the burner (remove the safety valve [C] and turn the burner upside down), and follow the process outlined in (3) to (13) above to restart. ...
- Page 4 Closing the needle valve will extinguish the flame and shut down the operation. ◇3. Because carbon tends to collect on the nozzles, clean the nozzles after every ten operations using ◇4. the attached wire. *Do not use a wire other than the attached one to clean the nozzles as any thick wire may reduce the heating power by widening the nozzle hole. Also, clean the nozzles from the nozzle end (boiler side). Do not loosen the screws of [E]. About heating power weaknesses, refer to the Causes and Countermeasures listed below ◇5. The wick end should always reach the bottom of the burner to ensure steady fuel flow and flame. ◇6. If the wick does not touch the bottom, heating power will be reduced. In such cases, push the wick down gently using a wire or similar object. Standard burning time is about 25 minutes. If burning time is over 25 minutes, it means that heating power is reduced and the operator must find and fix the cause(s). Possible cause Countermeasure Fuel absorbed moisture Replace remaining fuel with new alcohol. Excessive dust or Clean using wire provided. After removing the gland nut and carbon in nozzle needle, pass the wire through the holes in the nozzle. Foreign matter prevents When gas leakage is caused by something preventing the valve valve from closing from closing completely, clean it completely All specifications and models are subject to change without notice. http://www.saito-mfg.com SAITO SEISAKUSHO CO., LTD. 22-7, 3-chome, Tokagi, Ichikawa-shi, Chiba prefecture 272-0024, Japan Phone: 047-378-4156 FAX: 047-378-4155 - 4 -...
