1. Apply a thin layer of silicone lubricant to the four O-rings that are inside of the torch body.
Do not apply silicone to the brass electrical connectors.
Make sure that the O-rings are shiny. However, too much lubricant can prevent gas flow. Remove
unwanted lubricant if found.
2. Install the torch in the torch receptacle:
a. Turn the torch body up with light force until you feel it engage into position in the receptacle.
b. Use your hands to tighten the torch-coupler nut until the coupler nut cannot turn.
Do not use tools.
3. Make sure that the torch body is fully installed in the torch receptacle.
Make sure that there is no space between the torch body and torch receptacle.
