LIGHTING AND OPERATION

LEAK TESTING

Whenever the hose or torch is connected to a cylinder and prior to attempting to ignite torch: check all joints and couplings
to ensure against loose connections. With the fuel valve and oxygen valve closed and without lighting, test the connections
between the fuel valve and fuel cylinder and between the oxygen valve and the oxygen cylinder with soapy water. If bubbles
appear, gas is leaking and torch must be repaired. Never use a flame to check for leaks. Conduct this test in a well-ventilated
and spark-free area where there are no open flames.
• Do not ignite the torch while oxygen is flowing to the torch.
• Point he tip of the torch (4) in a safe direction.
• To light with a spark lighter, (5) open fuel valve (1) slowly just before sparking. Hold spark lighter at a 45 degree angle to
the tip of the torch (4).
• Squeeze spark lighter to create sparks and remove once torch is lit.
Note: It is very difficult to light torch with valve fully open.
• Do not light with cigarette lighter or match.
• If ignition does not occur immediately upon opening the fuel valve, close the valve and wait 5 minutes before attempting
to ignite again. Failure to follow this instruction could result in a build up of flammable gas which if ignited could result in
a fireball that could cause injuries and property damage. Do not open the valve and allow gas to flow through the torch
without attempting to ignite the torch.
• After igniting, the flame will appear soft yellow. Adjust flame to be between 4 and 6 inches long.
• Then, slowly open the oxygen valve (2) until the flame has an inner blue flame about ¼ inch long. The outside flame may
be longer. This is the starting flame.
SHUT OFF AND STORAGE
• TURN OFF THE OXYGEN VALVE (2) BEFORE TURNING OFF THE FUEL GAS VALVE (1). Turning off the fuel gas valve while
oxygen is still flowing could result in a flash back and an explosion.
• When the torch is cool, disconnect the cylinders from the hoses and replace the protective caps on the cylinders.
• Disconnect the oxygen cylinder by holding the oxygen hose valve and turning the oxygen cylinder clockwise.
• Disconnect the fuel valve by holding the fuel hose valve and turning the fuel cylinder counterclockwise.
• Store the torch and cylinders separately and out of reach of children.
• Do not store torch and/or cylinders inside a vehicle.
