General Power Tool Safety Warnings\*

WARNING

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE!

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work Area Safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

- Keep children and by-standers away while operating a power. Distractions can cause you to lose control.

Electrical Safety

• Power tool plugs must match the outlet. Never mod ify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodi fied plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electrical shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

Personal Safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A mo ment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the OFF-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch ON invites accidents.
• Remove any adjusting key or wrench before turning the power tool ON. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, and clothing away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

Power Tool Use and Care

- Do not force power tool. Use the correct power tool for your application. The correct power tool will do the

job better and safer at the rate for which it is designed.

- Do not use power tool if the switch does not turn it ON and OFF. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

- Disconnect the plug from the power source and/or the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

- Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the tool. Power tools are dangerous in the hands of untrained users.

- Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

- Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

- Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

- Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. The use of the power tool for operations different from those intended could result in a hazardous situation.

Description

The RIDGID® 918 Roll Groover is designed to form rolled grooves in steel, stainless steel, aluminum, PVC pipes and copper tubes. The grooves are formed by hydraulically advancing the groove roll into the pipe, which is supported by the drive roll.

The 918 Roll Groover typically includes two groove and drive roll sets for grooving pipe:

• 2"-6" schedule 10 and 40 steel pipe
- 8"-12" schedule 10 and 8" Schedule 40 steel pipe

Other materials can be grooved – see tables in appendix. Other groove and drive shaft sets are required for other sizes and copper tubing.

A two-stage hydraulic hand pump is used to advance the groove roll into the pipe to form grooves. A groove depth gauge is provided to aid in groove set up and an adjustment nut is included to control groove diameter.

An adjustable stabilizer is provided to aid in maintaining tracking and control of the pipe during grooving, especially pipe lengths approaching the 8" minimum pipe length.

The groover can be driven by a variety of RIDGID machines. Different mounting kits are required for each machine.

WARNING ≥ 8" ≥ 200 mm

Keep hands away from grooving rolls. Do not wear loose fitting gloves. Fingers can be crushed between groove rolls, groove roll and pipe or between pipe and stabilizer wheel.

Keep hands away from ends of pipe. Do not reach inside pipe. Do not touch groove while operating. Burrs and sharp edges can catch and cut. Fingers

can be crushed between groove rolls or between groove rolls and pipe.

Keep guards in place. Do not operate the roll groover with the guard removed. Exposure to groove rolls may result in entanglement and serious injury.

Only groove pipe 8" (200 mm) or longer. Grooving shorter than specified pipe can result in entanglement and crushing injuries.

Do not use this roll groover with a power drive or threading machine that does not have a foot switch. Never block a foot switch in the ON position so it does not control the machine. A foot switch provides better control by letting you shut off the machine motor by removing your foot. If entanglement should occur and power is maintained to the motor, you will be pulled into the machine. This machine has high torque and can cause clothing to bind around your am or other body parts with enough force to crush or break bones or cause striking or other injuries.

Be sure that the roll groover, pipe, stands and machine are stable. Be sure the roll groover is properly set up and secured. This will help prevent tipping of the equipment and pipe. Properly support the pipe. This will help to prevent the tipping of the pipe and equipment.

Always wear eye protection. Wear steel toe footwear to help protect from tipping tools and falling pipe.

Set up and operate the roll groover according to these procedures to reduce the risk of injury from machine tipping, entanglement, crushing, striking and other causes, and to help prevent equipment damage.

1. Confirm that the machine and work area is properly set up and that the work area is free of bystanders and other distractions. The operator should be the only person in the area when the machine is operated.
2. Position the foot switch for proper operation as shown in Figure 19.
3. Check the roll groover for proper operation. While keeping your hands clear of moving parts:

- Move the power drive/threading machine REV/O-OFF/FOR switch to the REV position. Press and release the foot switch. Drive roll should rotate clockwise (see Figure 15) matching the pipe rotation decal on the groover. If the groover does not rotate in the correct direction, or the foot switch does not control the machine operation, do not use the machine until it has been repaired.

- Depress and hold the foot switch. Inspect the moving parts for misalignment, binding, odd noises or any other unusual conditions. Confirm that the machine rotates less than 58 rpm. Higher speeds can increase the risk of injury. Remove foot from the

foot switch. If any unusual conditions are found, do not use the machine until it has been repaired.

- Move the REV/O-OFF/FOR switch to the OFF position, and with dry hands unplug the machine.

Pipe Preparation

NOTICE These are generalized instructions. Always follow grooved coupling manufacturer's specific recommendations for pipe end preparation. Failure to follow these recommendations may lead to an improper connection and cause leaks.

1. Be aware of pipe specifications acceptable for grooving. Out of specification pipe can cause leaks and other issues. Pipe out-of-roundness must not exceed total O.D. tolerance listed in the Standard Roll Groove Specifications, Table II.

2. Cut pipe to proper length. Be aware of the minimum pipe lengths for grooving.

3. 5" and smaller diameter pipe should not be shorter than 8" (200 mm) long.

4. 6" to 12" diameter pipe should not be shorter than 10" (250 mm) long.

Grooving shorter pipe increases the risk of injury from crushed fingers and entanglement.

1. Make sure pipe end is cut square and free of burrs. Burrs can catch or cut gloves or fingers during grooving. Cut off method and large burrs can affect the quality of the groove made and tracking of the groover. Do not attempt to groove pipe that has been cut with a torch.
2. Remove all internal/external weld beads, flash, seams, scale, dirt, rust and other contaminants at least 2" back from the end of the pipe. Do not cut flats into gasket seat area, this could cause leaks. Contaminants can clog the drive knurls and prevent proper driving and tracking of the pipe while grooving.

Advance/Retract The Groove Roll

The movement of the groove roll is controlled by the hydraulic pump.

• To advance the groove roll, move the pump lever to the advance position, then move the pump handle up and down.
• To retract the groove roll, move the pump lever to the retract position. See Figure 11.

Advance Retract

Figure 11 – Pump Release Lever Position

Setting Adjustable Guard

1. Confirm the size of the pipe that is going to be grooved.
2. Locate the engraved pipe sizes on the guard face. Find the range of sizes that the pipe falls within.
3. Loosen the wing-screw. Adjust the position of the guard so that the correct range of sizes aligns with the position of the wing-screw. Properly adjust guard to reduce the risk of entanglement and serious injury (Figure 12).
4. Securely tighten the wing screw.

Chart A - Minimum/maximum pipe length to be grooved with one stand (in inches)

For longer pipes at least two stands should be used, with the two stands placed approximately 1/4 of the pipe length from the ends of pipe. Failure to properly support the pipe may allow the pipe or the pipe and machine to tip and fall. Always use a pipe stand – it helps to align the pipe and maintain proper tracking.

Figure 14 – Leveling Pipe

1. Advance the groove roll until it touches and lightly grips the pipe (Do not drive the groove roll into the pipe).

2. Confirm the pipe positioning. If the pipe is not properly positioned, the groove may not track properly.

3. The pipe end should be flush against the driveshaft flange.

4. The centerline of the pipe and the centerline of the drive shaft should be parallel. This can be checked with a level on top of the hydraulic cylinder and on the pipe. See Figure 14.

5. The roll groover/machine should be sitting firmly on the ground. If the machine is lifting off the ground at all, the pipe stand(s) are set improperly and should be adjusted.

6. Preferred Operation - Switch in REV Setting:

Slightly offset the pipe and pipe stands approximately 1/2 degree (about 1" over at 10 feet from the roll groover) towards the operator. Proper alignment of the pipe and roll groover helps to ensure proper tracking of the pipe while grooving (see Figure 15). This is proper offset for grooving with the machine in the REV switch setting, and works with the stabilizer.

Alternate Operation – Switch in FOR Setting: If using the machine in the FOR switch setting (such as with a 535 Auto Chuck Machine not converted to grip in both directions), then offset the pipe and pipe stands approximately 1/2 degree (about 1" over at 10 feet from the roll groover) away from the operator (see Figure 16). The pipe stabilizer cannot be used with the FOR switch setting – it may cause pipe to spiral out of the roll set.

Figure 16 – Offsetting the Pipe 1/2° Away from Operator, (Exaggerated)

1. Restrict access or set up guards or barriers to create a minimum 3' (1m) clearance around the equipment and pipe. This helps prevent non-operators from contacting the equipment or pipe and reduces the risk of tipping or entanglement.
2. With dry hands, plug the power drive/threading machine into a properly grounded outlet.

Setting/Adjusting Groove Diameter

NOTICE Due to differing pipe characteristics, a test groove should always be performed before the first groove of the day or when changing pipe size, schedule, material, or lot to reduce the risk of out of tolerance grooves. Groove diameter must be measured to confirm proper size.

1. Confirm that equipment is properly set up and pipe is

properly prepared and loaded. Improper set up and preparation can affect accuracy of groove diameter settings.

1. Groove roll should be contacting the pipe. If needed, advance the groove roll to just contact the pipe. It should not be gripping or making an indentation in the pipe.

2. Adjust the groove depth gauge so that the correct step of the gauge is under the head of the adjusting screw (Figure 17A). The groove depth gauge is designed for use with pipe. See "Setting The Groove Diameter For Copper Tubing" for use with copper tube.

3. Turn the adjusting nut clockwise until the head touches the step of the depth gauge. Turn the groove depth gauge to the grooving position (Figure 17B). If the gauge is not in the grooving position it will prevent grooving and may be damaged.

Figure 17A – Place Correct Step of Gauge Under Adjusting Head

Close-up of a mechanical clamp or measuring device with circular components and adjustment knobs (no visible text or symbols)

Figure 17B - Gauge in Grooving Position

1. Prepare a test groove (follow the steps for "Grooving Operation").

2. Measure the groove diameter. The best method for measuring the groove diameter is the use of a diameter tape (see Optional Equipment Section). Tightly wrap the diameter tape around the grooved section of the pipe. Make sure that the tape sits flat in the bottom of the groove, and read the groove diameter.

3. Compare the measured groove diameter to the required groove diameter as shown in Table II or III or as specified by the groove fitting manufacturer. If the measured groove is outside of the required groove diameter the adjustment nut can be adjusted to form a correct groove.

- To decrease groove diameter (deeper groove), turn the depth adjustment nut counterclockwise.

- To increase groove diameter (shallower groove), Turn the depth adjustment nut clockwise.

- Each 1/4 turn of the depth adjustment nut changes the groove diameter by approximately 0.025" (0.6 mm). Moving the nut one mark on the circumference changes the groove diameter by approximately 0.002" (0.05 mm).

1. Repeat steps 6-8 until the groove diameter is within specifications. If the groove is too large, the groover can be adjusted and the groove made smaller. If the groove is too small, another groove will need to be made. Proper groove diameter is important to ensure connection performance. Out of specification grooves could cause joint failure.

Stabilizer Operation

The stabilizer is used to apply slight force to 2/2" to 12" pipe to improve tracking. It is especially useful for short pieces of pipe, but can be used on all lengths of pipe. The stabilizer also reduces the swaying of longer, larger diameter pipe.

The stabilizer can only be used with the machine REV/O-OFF/FOR switch in the REV position (pipe rotation marked on groover, Figure 18). If used with the machine REV/O-OFF/FOR switch in the FOR position, the pipe will spiral/track out of the groove rolls.

1. Properly set up equipment and load pipe.

2. Set groove diameter.

3. Rotate the stabilizer crank handle to bring the roller in contact with the pipe. Rotate the crank handle an additional one (1) turn to preload the roller against the pipe (Figure 18). Do not reach across the pipe to adjust the stabilizer.

4. Groove pipe. During use, keep hands away from the groove rolls, stabilizer wheel and end of pipe. Do not groove pipe shorter than specifications and do not

reach inside pipe or touch the groove. This reduces the risk of crushing injuries.

If during grooving the pipe does not track properly, step off foot switch and stop grooving. Set up a new groove and rotate the crank handle an additional one half (1/2) turn to increase preload. Do not use excessive preload. This can damage the roller.

Once the stabilizer is set for a given size and type of material, it generally does not need to be readjusted or backed off when pipe is loaded and unloaded.

Figure 18 – Stabilizer Positioning

Grooving Operation

1. Confirm that equipment is properly set up and pipe is properly prepared and loaded. Properly adjust guard. Do not groove pipe shorter than 8".

2. Set groove diameter.

3. If needed, set the stabilizer position.

4. Assume a proper operating position to help maintain control of the machine and pipe (see Figure 19).

- Stand facing the roll groover on the REV/O-OFF/FOR switch side of the machine with convenient access to the switch, pump handle and pipe. Your left hand will be on the pump handle, and your right hand is clear of the pipe unless applying slight force to the pipe to maintain tracking (see Tracking Tips section).

- Be sure that you can control the foot switch. Do not step on foot switch yet. In case of emergency you must be able to release the foot switch.

- Be sure that you have good footing and balance and do not have to overreach.

Figure 19 – Proper Operating Position

1. Move the REV/O-OFF/FOR to the REV position.

2. Apply approximately a quarter stroke of the pump handle to force the groove roll into the pipe.

3. Depress the foot switch. The pipe will start to turn. Allow one full pipe rotation between quarter strokes of the pump handle. Do not advance the groove roll too aggressively – this can cause the pipe to spiral out of the roll set and poor groove form. Keep your hands clear of the groove set, pipe end and stabilizer wheel. Do not reach inside the pipe or touch groove.

Monitor the pipe as it is grooved. The end of the pipe should stay in contact with the drive shaft flange, and the pipe should stay in position. If the pipe starts to move out of position, step off of the foot switch and stop grooving. Keep your body clear in case the pipe comes out of the grip of the roll set. If the pipe starts to come out of position stop grooving and check set up. If the pipe end is damaged, a new groove will need to be prepared.

Continue applying a quarter stroke of the pump handle every pipe rotation.

When using the 1" roll set, it is especially important to not apply excessive force (improper groove diameter setting, undersized grooves, more than a quarter stroke of pump handle per rotation). This can damage the 1" drive roll.

1. When the depth adjustment nut contacts the top of the groover, allow the pipe to rotate at least two more full rotations to ensure uniform groove depth.
2. Remove foot from the foot switch.
3. Move the REV/O-OFF/FOR switch to the OFF position.
4. Retract the groove roll and remove the pipe from the roll groover.
5. Inspect and measure the groove.

Setting The Groove Diameter For Copper Tubing

When using the 918 Roll Groover for copper tube, the groove depth gauge on the groover cannot be used. It will give incorrect groove diameter.

1. Advance the groove roll just to touch and lightly grip the tube.
2. Make sure the groove depth gauge is in the grooving position. (Figure 17B)
3. Turn the adjustment nut until it is flush with the top plate of the groover.
4. Find the diameter and type of tube to be grooved on Table B and back the adjusting screw off the top plate the corresponding number of turns. For example, for 4" Type L copper, back the adjustment screw 1 turn.

Tracking Tips

A typical issue while roll grooving is the pipe "spiraling" or "walking off" the drive shaft or not "tracking" properly.

For good tracking, it is important that all instructions be followed. If, even after following all instructions, the pipe will not properly track, there are other options to improve tracking.

- Slightly increase the offset of the pipe (increase from 1/2 degree to 1 degree). See Figure 15.

• Tighten the stabilizer crank handle an additional 1/2 turn.
• The operator may need to apply slight force on the pipe while grooving to maintain tracking. This is usually only needed on shorter pieces of pipe when the stabilizer is not used. To do this, the operator should wear a leather glove in good condition and cup their hand around the pipe as shown in Figure 20 to pull the pipe slightly towards them. This may require that the power drive/threading machine stand be fixed to the floor to prevent movement during grooving. To reduce the risk of crushing and cutting injuries, keep hand away from the groove roll and the ends of the pipe, do not groove pipe shorter than recommended and do not reach inside pipe or touch groove.

Figure 20 – Applying Pressure on Pipe with Power Drive in REV direction

If the machine is run in the FOR direction, the stabilizer cannot be used. Move the stabilizer wheel away from the pipe. If the stabilizer is used in FOR, the pipe will spiral out of the groove rolls. If needed, the operator should wear a leather glove in good condition and use their right hand to push pipe slightly away from them as shown in Figure 21.

Inspect/Measure the Groove

1. Inspect the groove.

• Make sure that all features are present and fully formed. See Table II and Figure 31.
• Measure the groove diameter and make sure it is within specification.
- Check any other items required by the fitting manufacturer.
- Test the system in accordance with local codes and normal practice.

If any problems are found, the groove cannot be used. Proper groove diameter is important to ensure connection performance. Out of specification grooves could cause joint failure.

1. Measure the groove diameter with diameter tape (see Optional Equipment Section). Snugly wrap the diameter tape around the pipe in the groove. Make sure that the tape sits flat in the bottom of the groove, and read the groove diameter (see Figure 22). Compare the measured groove diameter to the required groove diameter as shown in Table II or III or as specified by the groove fitting manufacturer.

Preparing Machine for Transport

Before transporting, remove the 918 from the power drive/threading machine. Be aware of the equipment weight. Use appropriate methods when lifting or moving.

Storage

⚠ WARNING The 918 Roll Groover must be kept indoors or well covered in rainy weather. Store the machine in a locked area that is out of reach of children and people unfamiliar with roll groovers. This machine can cause serious injury in the hands of untrained users.

Maintenance Instructions

WARNING

Make sure machine is unplugged from power source before performing maintenance or making any adjustments.

Maintain the 918 Roll Groover according to these procedures to reduce the risk of injury.

Cleaning

Use a soft damp cloth to clean the roll groover.

Clean the drive roll knurls with a wire brush before use and as necessary during operation. When grooving stainless steel pipe, thoroughly clean the entire roll set with a stainless steel wire brush.

Lubrication

On a monthly basis (or more often if needed), lubricate the groover with a lithium based general purpose grease. Always lubricate the roll groover after roll set changes.

- Lubricate the groover at grease fittings (See Figure 23). Add grease until a small amount pushes out.

Figure 23 – Grease Fittings

- Apply a light lubricating oil to pivot points and areas of relative motion, such as the depth adjustment nut and the stabilizer feedscrew. Wipe any excess lubricant from exposed surfaces.

Hydraulic Fluid Level

Remove the reservoir filler cap (Figure 24). The oil level should come to the fill line when the pump is resting on its base and the ram is fully retracted. Use only ISO 15 hydraulic oil.

Close-up of a mechanical assembly with a black circular component and two bolts (no visible text or symbols)

Figure 24 – Reservoir Filler Cap

Once a year, or more often with heavy use or use in dusty conditions, the hydraulic oil should be changed. To drain oil, remove the reservoir filler cap and drain the oil in a container. Properly dispose of the used hydraulic oil per the Safety Data Sheet (SDS) and local requirements.

Hydraulic system may need air bled after changing fluid. To bleed hydraulic system, position ram lower than pump by tipping the machine on its side. Extend and return the cylinder piston several times to permit air to return to the pump reservoir.

Changing Roll Sets

NOTICE When changing roll set, always make sure drive roll and groove roll markings match. Mismatched parts can make improper grooves and cause leaks. Always change rolls as sets – do not mix rolls from different sets.

If installed, remove the roll groover from power drive or threading machine and place on a stable workbench.

Properly support the rolls and shafts while replacing.
