equipment.
Read all these instructions in this manual completely and carefully for your protection against
serious injuries.
Save this manual. Refer to them frequently and use them to instruct other users.
Stay alert, watch what you are doing and use common sense when operating a power tool. Never
operate machine when tired or under the influence of drugs or alcohol. A moment of inattention
while operating machine may result in serious personal injury.
Do not wear gloves, loose clothing or jewelry that can get caught in machine's moving parts and
cause serous injury. Cover up or tie up long hair. Keep sleeves and jackets buttoned for reduction
of risk any accident.
Always wear safety glasses.
Protect your hearing by earmuffs or earplugs. If you use machine daily or in a noisy area.
Protect your lungs by using dust mask when work area is dusty.
Keep your hands and face away from dies, cutter blade, auto-chuck or other moving parts.
Avoid accidental starting. Make sure switch is OFF position before plugging in. Plugging in tools in
that have the switch ON invites accidents.
Keep hands away from rotating die head or any parts. Stop the machine before wiping pipe or
screw. Allow the machine to come to a complete stop before touching the pipe, machine chucks,
or any rotating parts. This practice will prevent serious injury.
Do not over-reach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
Unplug power cord when not in use, before making any adjustments, changing accessories, or
storing the tools. Such prevention safety measures reduce risk of starting tool accidentally.
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a
matching outlet that is properly installed and grounded in accordance with all local codes and

installed by a qualified electrician.
2) Avoid body contact with grounded surfaces. If your body is grounded, There is an increased risk
of electrical shock
3) Never expose electrical tools to rain or wet condition. Water entering a tool will increase the risk of
electrical accident.
4) Do not abuse cord. Never carry machine by the cord or yank the cord to disconnect it from outlet.
Keep cord from heat, oil, sharp edges or moving parts. Replace damaged cords immediately.
Damaged cords will cause the risk of electrical shock.
5) When used outdoors, use only extension cord intended for use outdoors and so marked.
6) Use only three-wire extension cords which have three-prong grounding plugs and three-pole
receptacles which accept the tool’s plug.
7) Use extension cord in good condition. Make sure to use one heavy enough to carry the current the
machine will draw. An undersized cord will cause a drop on line voltage resulting in loss of power
and overheating. The extension cord chart shows the correct sizes to use depending on cord
length and ampere rating.

9) Keep all electric connections dry and off the ground. Do not touch plugs or tool with wet hands.
Reduce the risk of electrical shock.
5. Work Area Safety
1) Keep the work area clean. Cluttered work area invite accident.
2) Do not use machine in dangerous environment. Do not use machine near gasoline or other
flammables or gases, or in damp locations. Do not expose machine to rain or direct sunlight. Keep
work area well lighted.
3) Keep floors dry and free of slippery materials such as oil. Slippery floors invite accidents.
4) Keep children away from work area. All visitors should be kept at a safe distance from the work
area. Guard or barricade for the work area when work piece extends beyond machine will reduce
the risk of accident.
5) When not in use, machine should be stored in a dry and locked-up place out of the reach of
children.
6) Never leave the machine running unattended. Turn off the power and stay there until machine
comes to a complete stop.
6. Machine Safety
1) Threading machine is made to thread and cut pipe or bolt. Follow instruction on proper use of this
machine. Do not use for other purpose such as drilling holes or turning winches. Other uses or
modification this power drive for other applications may increase the risk of serious accident.
2) Secure machine to bench or stand. Support long heavy pipe with supports. This practice will

prevent tipping.
3) Remove hex keys and adjusting wrenches from machine before operation.
4) Do not force machine. It will do the job better and safer at the rate for which it is designed.
5) Maintain the machine with care. Periodically check lubrication and consumables. Replace cutting
oil or dies when necessary. Inspect extension cord periodically and replace if damaged.
6) Use only manufacturer's recommended accessories. Consult this manual for recommended
accessories. Using improper accessories may increase the risk of injury.
7) Do not use machine if switches are broken or switch does not turn it ON or OFF. Any tool that can
not be controlled with the switch is dangerous and must be repaired.
8) Check for broken or damaged parts and alignment of moving parts before using machine. Repair
or replace damaged parts by an authorized dealer to insure proper operation of the machine. Use
only genuine MCC replacement parts. Poorly maintained machine cause risk of accident.
9) Keep handles dry and clean and free from oil and grease for better control of the machine.
7. Electrical Connection
Your MCC Machine is powered by a precision built electric motor.
It should be connected only to a power source that satisfies the power input listed on the machine's
name plates.
If the name plate is marked AC or 60 or 50Hz, the machine must be operated only with alternating
current (normal household current).
Never operate the machine with a direct current (DC), such as a generator. A substantial voltage drop
will cause a loss of power and overheating.
If the machine does not operate when plugged into an outlet, make sure the power supply rating.
WARNING: Keep the cord away from the work area and position the cord so that will not be
caught on the work pieces, tools, or other objects during threading.
