1.1 General machine safety precautions

Read and understand the following important safety information:
1.1.1 Machine safety
1. The machine casing is mainly made of aluminum alloy to reduce weight. For this reason,
be careful not to drop a heavy item on the machine, or not drop the machine when carrying
it , since the alloy is not designed to withstand such impact.
2. When mounting hoses to the torch and distributor, tighten the nut with the attached
wrench. After mounting, be sure to check there is no gas leak with a detection liquid. If a gas
leak is found, retighten the nut firmly.
3. When fixing a tip to the torch, tighten the nut with the two wrenches attached. In addition,
avoid damaging the taper part of the tip since this may cause backfire.
4. Never disassemble the machine other than during maintenance and inspection. Otherwise,
malfunction will result.
5. Never remodel the machine. Remodeling is very dangerous.
6. Always turn the power off when not in use.
7. Never use the machine outdoors when the weather is wet. This will cause failure of the
machine and could cause a fatal accident by electric shock.
