1.1 GENERAL MACHINE SAFETY PRECAUTIONS
Read and fully understand the following important safety information:
1.1.1
Machine safety
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.
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.
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.
1. Never disassemble the machine other than during maintenance and inspection. Otherwise,
malfunction will result.
2. Never remodel the machine. Remodeling is very dangerous.
3. When changing the travel direction, make sure that the direction switch is in the neutral (stop)
position, and operate the direction switch after the machine has stopped.
4. Always turn the power off when not used.
5. 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.
