WARNING
IMPROPER HANDLING AND MAINTENANCE OF
COMPRESSED GAS CYLINDERS AND REGULATORS
CAN RESULT IN SERIOUS INJURY OR DEATH! Always
secure gas cylinders to the tank bracket kit, a wall, or other
fixed support to prevent the cylinder from falling over and
rupturing. Read, understand, and follow all the
COMPRESSED GASSES AND EQUIPMENT HAZARDS in
the SAFETY SUMMARY at the front of this manual.
Secure your gas cylinder to the tank bracket kit, a wall, or other
fixed support.
1. Remove the protective cap from the cylinder and inspect
the regulator connecting threads for dust, dirt oil, and
grease. Remove any dust or dirt with a clean cloth. DO
NOT ATTACH THE REGULATOR IF OIL, GREASE, OR
DAMAGE ARE PRESENT.
WARNING
IMPROPER HANDLING AND MAINTENANCE OF
COMPRESSED GAS CYLINDERS AND REGULATORS
CAN RESULT IN SERIOUS INJURY OR DEATH! To
reduce the risk of injury or death, always stand to the side of
the cylinder opposite the regulator when opening the cylinder
valve, keeping the cylinder valve between you and the
regulator. Never aim the open cylinder valve port at yourself
or bystanders. Failure to comply with this warning could
result in serious personal injury.
2. Open the cylinder valve FOR JUST AN INSTANT to blow
out any foreign matter inside the valve port to reduce the
risk of plugging or damaging the regulator.
3. Screw the preset regulator supplied with this welder (see
Figure 3) into the cylinder valve and tighten with a wrench.
