SETTING CUTTING FLAME WEAR GLOVES & #6 LENS GOGGLES HOLD TORCH IN BOTH HANDS USE NEUTRAL FLAME TOO MUCH ACETYLENE SENDS FLAME AWAY FROM TIP TOO LITTLE CAUSES BLACK SMOKE 11/18/2018

OBTAINING NEUTRAL FLAME 1. OPEN ACETYLENE 1/2 TURN 2. USE STRIKER TO LIGHT 3. OPEN OXYGEN SLOWLY UNTIL FLAME IS NEUTRAL Flame Tip 11/18/2018

CUTTING PROCEDURE PREHEAT UNTIL CHERRY RED PRESS OXYGEN LEVER MOVE STEADLY ACROSS METAL IF YOU MOVE TOO FAST CUTTING STOPS AND MUST PREHEAT AGAIN 11/18/2018

TORCH SAFETY #6 FILTER LENS FASTEN CYLINDERS WITH CHAIN KEEP SAFETY CAPS ON CYLINDERS CHECK FOR LEAKS WITH SOAPY WATER NEVER PUT OIL ON EQUIPMENT 11/18/2018

SAFETY CONTINUED OPEN ACETYLENE CYLINDER 1-1/2 TURNS POINT TIP AWAY FROM YOU AND OTHERS USE PROPER PRESSURE (LESS THAN 15 PSI) USE STRIKER NOT MATCHES NEVER LAY LIGTHED TORCH DOWN 11/18/2018

SHUTTING DOWN PROCEDURE TURN OFF ACETYLENE FIRST AT TORCH TURN OFF OXYEN AT TORCH CLOSE CYLINDERS DRAIN HOSES 11/18/2018
