cartridge valve. Secure the device against tilting and slipping on the loading surface. Store
and transport only with the containers upright. Reusable containers must be filled only by
authorized facilities. Refilling in an unintended manner can cause severe accidents.
4.1 Set-up
Change the gas cartridges in a well-ventilated area, preferably outdoors.
- Make sure that all valves are closed before work begins.
- During set-up, turn the oxygen pressure regulator tight with the wrench.
- Screw the MAXIGAS one-way container rightward into the gas fine regulator valve. Make
sure that the tread begins and moves correctly. Screwing it in on a slant voids the warranty.
- Before igniting, make sure that the connections between the containers and the regulator
valves have no gas leaks. (Use leak detection spray or soapy water.)
A Open the oxygen tank valve.
B Depending on the nozzle and the material thickness, adjust the working pressure to a
setting (see technical data).
C Opening the oxygen pressure regulator valve.
D Now opens the gas regulator valve about a half turn.
E Opening the oxygen valve hand dial and adding oxygen.
F Open the fuel gas valve dial and light the gas flame.
G Setting the gas flame. The flame must already be burning visibly from the nozzle tip.
H Adjust the heating flame by opening or choking the gas and oxygen feed.
I Use only goggles that comply with DIN4646 and 58210/1.
All connections must be tightened or loosen using the wrench included.
After the gas valve has been opened, ignition must occur immediately, because
otherwise escaping gases can detonate.
Shut-down:
Shut the device down in the opposite sequence, but first always turn off the gas. Always close
the tank valve when work is interrupted.
5 Start-up
5.1 Lighting the burner
First open the gas regulator valve and light the gas; then open the oxygen valve and then adjust
the flame. The flame must already be burning visibly from the nozzle tip.
Ignite the gas / oxygen mixture by using one of the appropriate gas lighters at the burner nozzle.
(It can create black soot).
5.2 Setting the flame
With the hand dial marked red on the handle, adjust the size and appearance of the flame. If the
flame cannot be ignited or cuts off, the gas pressure is too high. In that case, choke off the gas at
the torch handle (the dial marked red) by turning it rightward.
The oxygen valve (the dial marked blue) must be completely open at the torch handle.
If the flame looks yellow, there is too much gas. Carefully choke the gas valve (the dial marked
red) at the torch handle by turning it farther leftward.
