a) STARTING PREPARATIONS

Fill the fuel tank short of overflowing. If the Swingfire is connected to a fuel supply system, fill it with only 1 quart of fuel.

Tighten the fuel tank cap.

Check the air shut off valve by pushing the pressure pin in. It must bounce back.

Check the position of the diapragm valve. Turn it all the way towards the "+" position.

If the Swingfire is used in connection with a heat exchanger, install the heat exchanger as follows:

Open the wing nut all the way counterclockwise. Check if gasket is in position and of good quality. Insert Swingfire into heat exchanger and set hand pump lever in a vertical position.

Tighten Swingfire well by fastening wing nut clockwise.

A tight fit is most important if a Turboheater is used. In this case the connecting flanges must be absolutely flush. This is assured if the wing nut has been turned 16 times in the tightening process after having been opened completely. If Turboheater is attached, check if overheating switch at turbo heater shows the "operation" position. If not, eliminate reason for trouble at Turboheater, then set overheating switch back to "operation".

Plug cable into the starting cable connector and battery after checking battery voltage for 12 or 24 volt.
CAUTION: Battery voltage must be identical to voltage shown on hand pump lever.
To check actual flow of current you should hear a distinct humming tone.

b) HOW TO START THE SWINGFIRE AT OUTSIDE TEMPERATURES DOWN TO 0 DEGREES F (-18C)

If Swingfire is attached to a heat exchanger, open the cover a bit so that you are able to hear the pulsating sounds better.

Then follow this sequence:

1) close fuel regulator knob.

2) move pump lever forward and backward in a firm and regular manner.

3) after 3 or 4 movements open the fuel regulator knob 1/2 - 1 turn with one hand, while continuing to pump until first pulsating sounds are heard.

4) keep on pumping with one hand, while adjusting the fuel regulator knob with the other hand until the pulsating sounds come in equal intervals. Once this is the case, stop pumping.

5) keep Swingfire running for 3-5 minutes and fine adjust it. Close cover and remove electrical connection cable

Fine adjustment procedure to follow.

STARTING INSTRUCTIONS AT OUTSIDE TEMPERATURES BELOW 0 DEGREES F (-18C)

Start heater as described in section a) with the following 2 exceptions:

1) Pull ignition switch and hold.
for at least 2 minutes at temperatures down to -20F;
for at least 3 minutes at temperatures down to -30F;
for at least 4 minutes at temperatures down to -40F;
for at least 5 minutes at temperatures down to -50F;
before you start pumping the lever ( as explained under section b) line 3)

2) Open the fuel regulator knob to 1-1 1/2 turns at these low temperatures.

c) FINE ADJUSTMENT OF SWINGFIRE

A warm Swingfire heater needs less fuel than a cold one. For this reason the fuel supply has to be fine adjusted. Too much fuel will choke the heater - too little fuel results in irregular pulsations. In both cases the Swingfire might cease to operate.
The heater works properly if the sound of pulsations is regular and strong meaning that the right amount of air coming in through the diapragm valve is mixed with the right amount of fuel. This is achieved by correct adjustment of the fuel regulator knob. The only function of this knob is to achieve the most favourable mixture of fuel and air.
The heat output cannot be adjusted by this knob.

d) COMMON MISTAKES MADE WHEN STARTING THE SWINGFIRE

If you move the pump lever too fast or open the regulator knob too wide, too much fuel is entering into the mixing chamber. The fuel mixture becomes too rich and cannot be ignited anymore. White fuel fog leaves the pulsation pipe but no pulsation takes place.
REMEDY: Close the fuel regulator knob, pump and ignite until surplus fuel has been blown out of the pulsation pipe. Once pulsations have started again, open fuel regulator knob 1/2-2 turns and continue to pump and ignite, at the same time adjust fuel supply with the regulator knob until pulsations come in equal intervals.
If a great deal of fuel has been pumped into the mixing chamber and the fuel has overflown from the diaphragm valve into the chamber, the remedy is as follows;

remove connecting cable, open cover, tilt Swingfire to the left so that fuel can run off. Clean up left over fuel and let it dry out.
When the Swingfire stops operating after a long time of operation,check if it has drowned (flooded?).
Sometimes 10-15 pump movements with simultaneous ignition and closed regulator valve, will bring back regular pulsations.
NOTE: Always empty the fuel tank if Swingfire heater is to be shipped.

e) HOW TO TURN THE SWINGFIRE OFF

Close fuel regulator knob completely.

f) SAFETY MEASURES AND ACCIDENT PREVENTION

As the exhaust fumes of the Swingfire are poisonous, they must not be allowed to enter a closed room inhabited by living beings.

If heaters are used to heat closed rooms from the outside (tents, truck cabins, or the like) the exhaust fumes must be moved a minimum of 7 feet into the air by an air tight pipe.
