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.
Personal Safety
• Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use tool while tired or under the influence of drugs, alcohol, or medications. A moment
of inattention while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts.
• Avoid accidental starting. Be sure switch is OFF before plugging in. Carrying tools with your
finger on the switch or plugging in tools that have the switch ON invites accidents
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard
hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
• Do not use tool if switch does not turn it ON or OFF. Any tool that cannot be controlled with
the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting
the tool accidentally.
• Store idle tools out of the reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
• Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool's operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended for your tool. Accessories that may be suitable
for one tool may become hazardous when used on another tool.
• Keep handles dry and clean; free from oil and grease. Allows for better control of the tool.
Machine Safety
• Secure machine to bench or stand. Support long heavy pipe with pipe supports. This
practice will prevent tipping.
• Do not wear gloves or loose clothing when operating machine. Keep sleeves and jackets
buttoned. Do not reach across the machine or pipe. Clothing can be caught by the pipe or
machine resulting in entanglement and serious injury.
• Do not use this machine if the switch is broken.
• Keep hands away from rotating pipe and fittings. Stop the machine before wiping pipe
threads or screwing on fittings. Allow the machine to come to a complete stop before touching
the pipe or machine chucks. This practice will prevent entanglement and serious injury.
• Do not use this machine to make or break fittings. This practice is not an intended use of the
machine and can result in serious injury.
• Tighten chuck handwheel and engage rear centering device on the pipe before turning on
the machine. Prevents oscillation of the pipe.
• Keep covers in place. Do not operate the machine with covers removed. Exposure to
moving parts may result in entanglement and serious injury.

Description
The SQ80C1 threader is an electric motor-driven machine which centers and chucks pipe,
conduit and rod (bolt stock) and rotates it while threading, cutting and reaming operations are
performed. Threading dies are mounted in self-opening die heads. An automatic oiling system
is provided to flood the work with thread cutting oil during threading operations.

Operating Instructions
Installing Pipe In Threader
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.
Tighten the rear centering device around the pipe by using a counterclockwise 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.

Installing dies (Fig 2)
1. Place Self-Opening Die Head flat on bench with
numbers UP.
2. Make sure trigger assembly is released.
3. Loosen clamp lever.
4. Pull lock screw out of size bar slot so that roll pin in
lock screw will bypass slot. Position size bar so that
index line on lock screw is all the way to the end of
REMOVE DIES position.
5. Remove dies from die head.
6. Insert new dies to mark. Die numbers 1 through 4
must agree with those on die head.
7. Rotate cam plate until roll pin on lock screw can be
positioned in slot. In this position dies will lock in die
head. Make sure roll pin points toward end of size bar
marked REMOVE DIES.
8. Adjust die head size bar until index line on lock
screw is aligned with proper size mark on size bar.
(For bolt threads, align index line with BOLT line on size bar.)
9. Tighten clamp lever.
10. If oversize or undersize threads are required, set the index line in direction of OVER or
UNDER size mark on size bar.
Threading Pipe
1. Swing cutter and reamer to UP position.
2. Swing die head to DOWN position with throwout lever set to CLOSE position.
3. Switch on to start machine.
4. Turn carriage handle to bring dies against end of pipe. Pressure on handle will start dies.
5. Self-Opening Die Head (Figure 3 & 4) –When die head end of pipe contacts trigger,
throwout lever is automatically opened on tapered threads.
6. Turn off switch and turn carriage handle to back die head off.
