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.
SAVE THESE INSTRUCTIONS!
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.
• 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.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These
cords are rated for outdoor use and reduce 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.
• Use proper extension cords. (See chart.) Insufficient conductor size will cause excessive voltage
drop and loss of power.

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.

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.
Grounding prong
• 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.
2
• Keep all electric connections dry and off the
ground. Do not touch plugs or tool with wet hands.
Reduces the risk of electrical shock.
• 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.
• Remove adjusting keys before turning the tool
ON. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and bal-

300 Power Drive
ance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
• 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.
Service
• Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified repair personnel could result in injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance
Section of this manual. Use of unauthorized parts or
failure to follow maintenance instructions may create a
risk of electrical shock or injury.
Specific Safety Information
WARNING
Read this operator’s manual carefully before using
the 300 Power Driver. Failure to understand and follow the contents of this manual may result in electrical shock, fire and/or serious personal injury.

Department at (800) 519-3456 if you have any questions.
WARNING
Foot Switch Safety
Using a power drive or threading machine without a
foot switch increases the risk of serious injury. A
foot switch provides better control by letting you
shut off the motor by removing your foot. If clothing
should become caught in the machine, it will continue to wind up, pulling you into the machine. Because
the machine has high torque, the clothing itself can
bind around your arm or other body parts with
enough force to crush or break bones.
Machine Safety
• Power Drive is made to thread and cut pipe or
bolt and to power RIDGID roll grooving equipment. Follow instructions on proper use of this
machine. Do not use for other purposes such
as drilling holes or turning winches. Other uses or
modifying this power drive for other applications may
increase the risk of serious injury.
• 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.
• Operate machine from side with REV/OFF/FOR
switch. Eliminates need to reach over the machine.
• Do not use this machine if the foot switch is broken or missing. Foot switch is a safety device to
prevent serious injury.
• 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 RIDGID Model 300 Power Drive 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.
Forward (clockwise) or Reverse (counterclockwise)
rotation can be selected with the FOR/OFF/REV switch
and a foot switch provides ON/OFF control of the motor.
The threading, cutting and reaming operations can be
performed by conventional hand tools or tools designed for
mounting on the Power Drive. A manual oiling system is
available to flood the workpiece with thread cutting oil during the threading operation. Geared Threaders can also be
used with the Power Drive to thread larger diameter pipe.
The RIDGID Model 300 Power Drive can also be used
as a power source for roll grooving equipment. Designed
to attach to the support arms of the Power Drive, the roll
grooving equipment forms standard roll grooves on a
variety of pipe sizes and materials.

your application. The correct tools and accessories
allow you to do the job successfully and safely.
Accessories suitable for use with other equipment
may be hazardous when used with this Power Drive.
9. Clean any oil, grease or dirt from all handles and
controls. This reduces the risk of injury due to a tool or
control slipping from your grip.
Inspect the cutting edges of your tools and dies. If
necessary, have them replaced prior to using the
Power Drive. Dull or damaged cutting tools and
dies can lead to binding, tool breakage and poor
quality threads.
10. Clean metal shavings and other debris from the chip
tray of the 418 Oiler. Check the level and quality of the
thread cutting oil. Replace or add oil if necessary.
NOTE! Thread cutting oil lubricates and cools the threads
during the threading operation. A dirty or poor
grade cutting oil can result in poor thread quality.
To prevent serious injury, inspect your Power
Drive. The following inspection procedures should
be performed on a daily basis:

Machine and Work Area Set-Up
• Stand facing the directional switch.
• Use the foot switch with his left foot.
WARNING
• Have convenient access to the directional switch,
tools and chucks without reaching across the
machine.
To prevent serious injury, proper set-up of the
machine and work area is required. The following
procedures should be followed to set-up the machine:
Machine is designed for one person operation.
1. Locate a work area that has the following:
• Adequate lighting.
• No flammable liquids, vapors or dust that may ignite.
• Grounded electrical outlet.
• Clear path to the electrical outlet that does not
contain any sources of heat or oil, sharp edges or
moving parts that may damage electrical cord.
• Dry place for machine and operator. Do not use
the machine while standing in water.
9. Plug the Power Drive into the electrical outlet making
sure to position the power cord along the clear path
selected earlier. If the power cord does not reach
the outlet, use an extension cord in good condition.
WARNING
To avoid electrical shock and electrical fires, never use
an extension cord that is damaged or does not meet the
following requirements:
• Level ground.
2. Clean up the work area prior to setting up any equipment. Always wipe up any oil that may have splashed
or dripped from the machine or oiler to prevent slips
and falls.
3. Set up the Power Drive on a flat, level surface.
• For a Power Drive mounted on a 1206 Stand,
open legs of stand and push down on the tray.
Legs should be stiff and stand should not wobble.
NOTE! To increase or decrease leg stiffness, refer to
instructions on “Mounting On 1206 Stand”.
• The cord has a three-prong plug similar to shown
in Electrical Safety section.
• The cord is rated as “W” or “W-A” if being used
outdoors.
• The cord has sufficient wire thickness (14 AWG
below 25′/12 AWG 25′ - 50′). If the wire thickness is
too small, the cord may overheat, melting the cord’s
insulation or causing nearby objects to ignite.
WARNING To reduce risk of electrical shock, keep
all electrical connections dry and off the ground. Do
not touch plug with wet hands.
10. Check the Power Drive to insure it is operating properly.
4. If the workpiece extends more than four (4) feet
beyond the Power Drive, use one or more pipe stands
to prevent tipping and the oscillation of the pipe.
5. If the workpiece extends beyond the Power Drive, setup guards or barricades to create a minimum of
three (3) feet of clearance around the Power Drive
and workpiece. This “safety zone” prevents others
from accidentally contacting the machine or workpiece
and either causing the equipment to tip or becoming
entangled in the rotating parts.
6. If necessary, fill the 418 Oiler with RIDGID Thread
Cutting Oil. Position the oiler under the front of the
Power Drive (Figure 3).
7. Make sure FOR/OFF/REV switch is in the OFF position.
