General Safety Information
WARNING! Read and understand all instructions. Failure to follow all instructions listed
below may result in electric shock, fire, and/or serious personal injury.
Work Area Safety
•Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents. Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Tools create sparks which may ignite the dust or fumes.
•Keep bystanders, children, and visitors away while operating a tool. Distractions can
cause you to lose control.
•Keep floors dry and free of slippery materials such as oil. Slippery floors invite accidents.
•Guard or barricade the area when work piece extends beyond machine. A guard or
barricade that provides a minimum of three (3) feet clearance around the work piece will
reduce the risk of entanglement.
Electrical Safety
•Grounded tools must be plugged into an outlet, properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you
are in doubt as to whether the outlet is properly grounded. If the tool should electrically
malfunction or break down, grounding provides a low resistance path to carry electricity
away from the user.
•Avoid body contact with grounded surfaces. There is an increased risk of electrical
shock if your body is grounded.
•Don't expose electrical tools to rain or wet conditions. Water entering a tool will increase
the risk of electrical shock.
•Do not abuse cord. Never use the cord to carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electrical shock.
•Use only three-wire extension cords which have three-prong grounding plugs and three-
pole receptacles which accept the tool's plug. Use of other extension cords will not ground
the tool and increase the risk of electrical shock.
•Keep all electric connections dry and off the ground. Do not touch plugs or tool with wet
hands. Reduces the risk of electrical shock.

Operating Instructions
Installing Pipe In Threader
Relevant parts' name, please refer to the photos within this manual.
Adding threading oil in the oil reservoir, when the machine is switched on, the oil will
automatically cycle.
1. Check to insure the cutter, reamer and die head are swung to UP position.
2. Mark the pipe at the desired length if it is being cut to length.
3. Insert the pipe into the Threading Machine so that the end to be worked or the cutting
mark is located about 12 inches to the front of the speed chuck jaws (Fig 1).
4. Insert workpieces less than 2 feet long from the front of the machine. Insert longer pipes
through either end so that the longer section extends out beyond the rear of the Threading
Machine.
5. Tighten the rear centering device around the pipe by rotation of the handwheel at the
rear of the Threading Machine. This prevents movement of the pipe that can result in poor
thread quality.
6. Secure the pipe by using repeated and forceful counterclockwise spins of the speed
chuck handwheel at the front of the Threading Machine. This action “hammers” the jaws
tightly around the pipe.
