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 flam mable liquids, gases, or dust. Electric motors create sparks which may ignite the dust or fumes.
• Keep by-standers, 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.

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 tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.

Grounding prong Cover of grounded outlet box Grounding prong

• Avoid body contact with grounded surfaces. There is an increased risk of electrical shock if your body is grounded.
• Do not 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 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 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.

• Keep all extension cord connections dry and off the ground. Do not touch plugs with wet hands. This practice reduces 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.

Minimum Wire Gauge for Extension Cord
Nameplate Amps	Total Length (in feet)
	0 – 25 26	-50 51 – 100
0 – 6 18	AWG 16 AWG	16 AWG

10 – 12 16	AWG 16 AWG	14 AWG
12 – 16 14	AWG 12 AWG		NOT RECOMMENDED

Personal Safety

• Stay alert, watch what you are doing and use common sense when operating a tool. Do not use tools 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. Plugging in tools that have the switch ON invites accidents.
• Remove wrenches or 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 over-reach. Keep proper footing and balance 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 tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model. 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 Roll Groover. Failure to understand and follow the contents of this manual may result in electrical shock, fire and/or serious personal injury.

Call the Ridge Tool Company, Technical Service Department at [phone] if you have any questions.

WARNING Foot Switch Safety

Using a threading machine or power drive 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.

Roll Groover Safety

• Roll Groovers are made to groove pipe and tubing. Follow instructions in Operator's Manual on machine uses. Other uses may increase the risk of injury.
• Keep hands away from grooving rolls. Do not wear loose fitting gloves when operating unit. Fingers could get caught between grooving and drive rolls.
• Never groove pipe shorter than what is recommended. Increases risk of fingers being crushed by grooving rolls.
• Set-up groover on a flat, level surface. Be sure the machine, stand and groover are stable. Will prevent tipping of the unit.
• Do not wear loose clothing. Keep sleeves and jackets buttoned. Do not reach across the machine or pipe. Clothing can be caught by the pipe resulting in entanglement and serious injury.
• Do not use this Roll Groover with a Power Drive or Threading Machine that does not have a foot switch. Foot Switch is a safety device to prevent serious injury.
• Be sure groover is properly secured to the power drive or threading machine. Carefully follow the setup procedures. Will prevent tipping of the pipe or grooving unit.
• Properly support pipe with pipe stands. Use two pipe stands to groove pipe over 36" long. Prevents tipping of the unit.
• Use only power drives and threading machines that operate under 58 RPM. Higher speed machines increase the risk of injury.
• When grooving pipe, keep hands away from the end of the pipe. Do not reach inside pipe end. Will prevent being cut on sharp edges and burrs.
• Lock foot switch when not in use. (See Figure 1.) Avoids accidental starting.

Figure 12 – Forming the Roll Groove

⚠ WARNING If pipe begins to "walk off" the drive roll, stop the machine and check "Pipe Set-Up" procedure.

1. To help prevent "walking", apply pressure on pipe with right hand, away from operator when running the power drive or machine in FORWARD mode, toward operator when running the power drive or machine in REVERSE mode.

NOTE! If power source runs in FOR position, push the pipe away from operator. If power source runs in REV, pull the pipe towards operator.

1. With pipe tracking properly and backside of pipe against drive roll flange, step on foot switch and con-

tinue downward pressure until feed handle rests on the base of 916 Roll Groover.

NOTE! Do not overfeed upper groove roll. Maintain constant downward pressure, pausing to allow one pipe revolution before increasing downward pressure.

1. After feed handle comes to rest on base of 916 Roll Groover allow two (2) complete pipe revolutions to even out groove depth.

2. Release foot switch and slip directional switch to OFF.

3. Pull feed handle upward and check groove diameter (See Table I).

NOTE! Two measurements 90 degrees apart should equal the "C" dimension or measure with a PI tape.

1. To decrease groove diameter, tighten depth adjustment screw. To increase groove diameter, loosen depth adjustment screw.

NOTE! Once groove depth is determined, additional grooves will have the same depth.

1. Periodically check groove depth with a "pi" or diameter tape. Coupling should fully seat in the groove without binding or excessive play.

NOTE! Pipe exceeding Fitting Manufacturer's "Maximum Flare Specifications" may prevent assembly of the couplings pad to pad, allowing possible pipe separation that could result in property damage. Also, joint leakage may result due to excessive gasket distortion/damage. Check to Fitting Manufacturer's specifications.

Model No. 916 Roll Grooving Tips

1. If pipe tends to walk off drive roll, increase offset dimension.

2. If drive roll flange shaves pipe end, decrease offset dimensions.

3. If pipe end flare is excessive, lower pipe end to level with roll groover.

4. If pipe wobbles and/or walks off drive roll, raise pipe end to level with groover.

5. Short lengths of pipe (under three feet) may require slight pressure to maintain the 12 degree offset dimension.

NOTE! When grooving pipe longer than 36" on Models 300 Compact or 1822-I Threading Machines that are mounted on folding stands, adjust the pipe to the same angle of the 916's drive shaft (Figure 13).
