. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed. PERSONAL SAFETY 4. Stay alert. Watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or medication.
TOOL USE AND CARE 14. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. 15. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with a sharp cutting edge are less likely to bind and are easier to control. Do not use a damaged tool. Tag damaged tools “Do not use” until 16.
SPECIFIC SAFETY RULES 1. Maintain labels and nameplates on the Heavy Duty Welding Kit. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 2. Maintain a safe working environment. Keep the work area well lit. Make sure there is adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris. 3. Prevent eye injury and burns.
5. Avoid overexposure to fumes and gases. Always keep your head out of the fumes. Do not breathe the fumes. Use enough ventilation or exhaust, or both, to keep fumes and gases from your breathing zone and general area. Where ventilation is questionable, have a qualified technician take an air sampling to determine the need for corrective measures. Use mechanical ventilation to improve air quality. If engineering controls are not feasible, use an approved respirator.
8. Proper cylinder care. Secure cylinders to a cart, wall, or post, to prevent them from falling. All cylinders should be used and stored in an upright position. Never drop or strike a cylinder. Do not use cylinders that have been dented. Cylinder caps should be used when moving or storing cylinders. Empty cylinders should be kept in specified areas and clearly marked “empty”. 9. Never use oil or grease on any inlet connector, outlet connector, or cylinder valves. 10.
UNPACKING When unpacking, check to make sure all the parts shown on the Parts Lists on pages 15-19 are included. If any parts are missing or broken, please call Harbor Freight Tools at the number shown on the cover of this manual as soon as possible. ASSEMBLY AND OPERATING INSTRUCTIONS For additional information regarding the parts listed in the following pages, refer to the Parts Diagrams on pages 15-19. 1. NOTE! The following instructions are for acetylene gas use only.
5. IMPORTANT! The Pressure Adjusting Screw (18) on the Acetylene Regulator and the Pressure Adjusting Screw (A18) on the Oxygen Regulator should be opened slightly by turning counterclockwise to relieve pressure on the Regulator diaphragms before opening the cylinder valves. If this is not done, pressure from the cylinders may damage the diaphragms and render the Regulators inoperable.

14. Open the Acetylene Control Valve (B8 with AC Label (B10)) about 1/4 turn, and ignite the acetylene gas coming out of the Nozzle (part D4). WARNING! Always point the Nozzle away from other people when lighting. (See Figures L, and M.) 15. Slowly open the Acetylene Control Valve (B8 with AC Label (B10)) further until the smoke subsides and the flame jumps away from the end of the Nozzle (part D4) slightly. (See Figure M.) 16.
INSPECTION, MAINTENANCE, AND CLEANING 1. WARNING! Make sure the Welding Kit is cool to the touch and disconnected from its oxygen and acetylene cylinders before performing any inspection, maintenance, or cleaning procedures. 2. BEFORE EACH USE, inspect the general condition of the Welding Kit. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged Welding Hoses (D1A, or D1B), and any other condition that may affect its safe operation.
