Keep the torch clean. Do not lubricate any of the parts. Oil or grease can cause
an explosion when in contact with oxygen.
• The holes in the cutting nozzle should be cleaned when necessary with
appropriate cleaning needles or with KR21 chemical cleaner. Do not use
drill bits, steel wire or similar objects for cleaning, as the channels inside the
nozzle will be damaged.
• Proper fl ames and an even fl ow of cutting oxygen cannot be obtained un-
less the edges of the nozzle holes are sharp.
• If the outlet end of the welding or cutting nozzle is damaged, it may be
repaired by polishing perpendicularly with a fi ne emery cloth laid on a fl at
