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 your 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 bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified 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.

Description, Specifications, Standard Equipment and Accessories

Description

The RIDGID 918-I Roll Groover forms rolled grooves in steel, stainless steel, aluminum, PVC pipe and copper tubing. The grooves are formed by the hydraulic feeding of a grooving roll into the pipe which is supported by a drive roll.

The 918-I Roll Groover includes two (2) groove and drive shaft sets that can groove the following pipe:

• 2″ – 6″ Schedule 10 and 40
• 8″ – 12″ Schedule 10 and 8″ Schedule 40

With additional roll sets, the groover can also be adapted to groove the following:

• 2″ – 6″ copper tubing (Types K, L, M, DWV)
• 1″ Schedule 10 and 40
• 11/4″ – 11/2″ Schedule 10 and 40

When properly used, the Model 918-I makes grooves that are dimensionally within the specifications of AWWA C606-87. Selection of appropriate materials and joining methods is the responsibility of the system designer and/or installer. Before any installation is attempted, careful evaluation of the specific service environment, including chemical environment and service temperature, should be completed.

Specifications

Roll Grooving Capacity (See Table II for wall thickness)

• 1″ to 12″ Schedule 10
•  1″ to 8″ Schedule 40
• 2″ – 6″ Copper Types K, L, M, DWV
• 2″ – 8″ Schedule 40 PVC

Do not use to groove 8″ Schedule 40 steel pipe harder than 150 BHN. Doing so may result in improperly formed grooves that do not meet required specifications.

• Sound measurements are measured in accordance with a standardized test per Standard EN 62841-1.

  • Sound emissions may vary due to your location and specific use of these tools.
  • Daily exposure levels for sound need to be evaluated for each application and appropriate safety measures taken when needed.

Roll Groover Assembly Instructions

To prevent serious injury, proper assembly of the Roll Groover is required. The following procedures should be followed:

Assembling Roll Groover

1.  To identify the parts for the 918-I Roll Groover, refer to the parts diagram and parts list.

2.  Attach right and left legs to the rear support/handle assembly using 3/8″ – 16 x 21/2″ hex screws and lock washers. Do not tighten screws.

3. Attach the tool tray assembly to the rear and front legs using the four (4) 3/8″ – 16 x 23/4″ hex screws and lock washers. Do not tighten screws.

4. Insert axle into tabs extending from the rear support/ handle assembly and secure using four (4) retaining rings.

5. Mount the roll groover/base assembly to the stand using four (4) 3/8″ – 16 x 21/2″ hex screws, washers and wing nuts. Be careful not to “hook” the switch assembly on the stand rail. Movement of the stand legs may be required to align the base assembly.
   Bolt heads go to top, wing nuts and lock washers to the bottom (stand) side. Installation of the last bolt requires opening of the motor cover.

6. Tighten the six (6) screws and four (4) wing nuts holding the leg and tray assemblies together. Slide the wheels onto the axle and install retaining rings to hold the wheels on the axle.

7. Cut the tie wrap that holds the hydraulic pump in place for shipping. Remove the bolts/wing screws from the bottom of the pump’s mounting plate.

8. Place the pump mounting plate over the hole and slot on the left side of the 918-I (left side as you look at the front of the 918-I). From the bottom of the base plate, insert the 3/8″ – 16 x 1″ bolt with washer into the hole and screw into pump mounting plate. Secure the bolt with the 3/8″ nut.

9. From the bottom of the base plate, insert the wing screw with lock washer into the pump mounting plate (through the slot) and tighten as required.

NOTE! During 918-I operation, the hydraulic pump should be in the outermost position. During transportation, the hydraulic pump should be in the inner most position.

Bolting the 918-I Stand to the Shop Floor

1. Mark the spot where the 918-I is to be bolted.
2.  Align spot with the 918-I stand bolt-down attachment holes (Figure 3).

Machine Inspection

Do not use this Roll Groover without a foot switch.

To prevent serious injury, inspect your Roll Groover.
The following inspection procedures should be performed on a daily basis.

1.  Make sure machine is unplugged and the switch is set to the OFF position.

2.  Make sure the foot switch is present and attached to the machine.

3.  Inspect the power cord and plug for damage. If the plug has been modified, is missing the grounding pin or if the cord is damaged, do not use the machine until the cord has been replaced.

4.  Make sure all bolts holding the Roll Groover and hydraulic pump to the base are tight.

5. Check that guard mounted to the roll groover is in place (Figure 3). Do not operate Roll Groover with guard removed. Exposure to moving grooving rolls may result in fingers being crushed.
   

6. Inspect the Roll Groover for any broken, missing, misaligned or binding parts as well as any other conditions which may affect the safe and normal operation of this equipment. If any of these conditions are present, do not use the Roll Groover until any problem has been repaired.
   

7. Lubricate the Roll Groover if necessary according to the Maintenance Instructions.

8. Use groover rolls and accessories that are designed for your Roll Groover and meet the needs of your application.
   The correct groover 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 Roll Groover.

9.  Clean any oil, grease or dirt from all equipment handles and controls. This reduces the risk of injury due to a tool or control slipping from your grip.

10. Inspect the groove rolls to insure they are not damaged or worn. Worn groover rolls can lead to pipe slippage and poor quality grooves.

Machine and Work Area Set-Up

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:

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.
   • Level ground

2. Clean up the work area prior to setting up any equipment. Always wipe up any oil that may be present.

3. Place machine on a flat, level surface. Be sure the groover and stands are stable. See Assembly Instructions for bolting 918-I stand to shop floor.

4. Properly support the pipe with pipe stands. See Chart “A” for maximum lengths with one (1) stand.                                                                                                                             ****Failure to properly support the pipe can result in the unit tipping or the pipe falling.

5.  Make sure switch is in the OFF position.

6. Position the foot switch so that the operator can safely control the roll groover and workpiece. It should allow the operator to do the following:
   • Stand with left hand on pump handle.
   • Use the foot switch with his left foot.
   • Have convenient access to the groover without reaching across the machine.
   Machine is designed for one person operation.

7. Plug the machine 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.                                                                                                                   To avoid electrical shock and electrical fires, never use an extension cord that is damaged or does not meet the following requirements.
   • 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’/12AWG 25′ – 50′). If the wire thickness is too small, the cord may overheat, melting the cord’s insulation or causing nearby objects to ignite.
   To reduce risk of electrical shock, keep all electrical connections dry and off the ground. Do not touch plug with wet hands.

8. Check the unit to insure it is operating properly.
   • Flip the switch to ON. Press and release the foot switch. Check that the groove roll rotates in a clockwise direction as you are facing the groover. Have the machine serviced if it rotates in the wrong direction or if the foot switch does not control its stopping or starting.
   • Depress and hold the foot switch. Inspect the moving parts for misalignment, binding, odd noises or any other unusual conditions that may affect the safe and normal operation of the machine. If such conditions are present, have the roll groover drive serviced.
   • Release the foot switch and flip the switch to OFF.

9. Check the groove and drive rolls to insure they are the correct size.
    Use of roll sets on both carbon and stainless steel pipe can lead to contamination of the stainless steel material. This contamination could cause corrosion and premature pipe failure. To prevent ferrous contamination, use roll sets dedicated for stainless steel grooving.

Operating the 918-I Roll Groover

Do not wear loose clothing when operating a Roll Groover. Keep sleeves and jackets buttoned. Do not reach across the machine or pipe.

Do not use this Roll Groover if it has a broken or missing foot switch. Always wear eye protection to protect eyes from dirt and other foreign objects.

Keep hands away from grooving rolls. Do not wear loose fitting gloves when operating groover. Use pipe stands to support pipe.

When grooving, keep hands away from end of pipe. Do not reach inside pipe end.

Pipe Preparation

1. Pipe ends must be cut square. Do not use cutting torch.

2. Pipe out-of-roundness must not exceed the total O.D. tolerance listed in groove specifications, Table 1.
   NOTE! Determine out-of-roundness by measuring maximum and minimum O.D. at 90 degrees apart.

3. All internal or external weld beads, flash or seams must be ground flush at least 2 inches back from pipe end.

NOTE! Do not cut flats on gasket seat area.

Pipe/Tubing Length

The following chart lists the minimum length of pipe or tubing to be grooved and the maximum length to be grooved with one (1) pipe stand.

Pipe Set-Up

1.  Pipe or tubing longer than the specified maximum
   lengths listed in Chart A must be supported with two (2) pipe stands. The second pipe support should be located 3/4 of pipe length from roll groover.
   ****Failure to use two stands may result in the unit tipping or the pipe falling.

2. Raise upper groove roll housing by placing pump release lever in RETURN position (away from operator) (Figure 4).

3. Square pipe and pipe support to roll groover making sure pipe is flush against drive roll flange (Figure 5).                    

4. Level pipe by adjusting pipe stand (Figure 6).

5. Slightly offset pipe and pipe stand (approximately 1/2 degree) toward operator (Figure 7).

Adjusting Roll Groove Depth

NOTE! Due to differing pipe characteristics, a test groove should always be performed when setting up or changing pipe sizes. The index depth adjustment knob must be reset for each diameter of pipe/tube.

1. Advance the upper groove roll by placing the pump release lever in ADVANCE position (toward operator) and pump the handle until the upper roll contacts the pipe to be grooved.
   NOTE! Upper roll should only touch the pipe surface. Care must be taken not to penetrate pipe surface with upper roll by applying excessive pressure.

2.  Turn down the indexed depth adjustment knob (clockwise) until it stops against the top of the machine (Figure 8).

3. Back the depth adjustment knob off one turn.

Forming the Roll Groove

Pipe wall thickness cannot exceed the maximum wall thickness specified in the “Pipe Maximum and Minimum Wall Thickness” Table II. Do not use to groove 8″ schedule 40 steel pipe that is harder than 150 BHN.

1.  Flip the switch from OFF and step on machine foot
   switch while applying downward pressure on the
   918-I pump handle. Allow one full pipe rotation between
   quarter strokes of the pump handle.
   ****If pipe begins to “walk off” the drive roll, stop the machine and check “Pipe Set-Up” procedure.

2. To help prevent “walking”, apply pressure on outside of pipe with right hand (Figure 9).
   ****Do not reach inside of pipe. Keep hands away from sharp edges and burrs on end of pipe.
   NOTE! Do not overfeed upper groove roll. Maintain constant even downward pressure, pausing to allow one pipe revolution per quarter stroke of the pump handle.

3. When the depth adjustment knob contacts the machine casting, allow two complete pipe revolutions to even out groove depth.

4. Release foot switch and retract upper groove roll by placing the pump release lever in the RETURN position (toward operator).

5. Check groove diameter before proceeding with additional grooves.

NOTE! Groove diameter should be measured using a diameter tape. To decrease groove diameter (increase groove depth), rotate the index depth adjustment knob one mark counter-clockwise. To increase groove diameter (decrease groove depth), rotate the depth adjustment knob clockwise.

Roll Grooving Tips with Model 918-I

1.  If pipe tends to “walk off” drive roll, increase offset dimension (Figure 7).
2. If drive roll flange shaves pipe end, decrease offset dimension.
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 roll groover.
5. Short lengths of pipe (under three feet) may require slight pressure to maintain the 1/2 degree offset dimension.

Grooving Short Lengths of Pipe

Without Stabilizer

1. Properly set-up pipe to ensure pipe is level and square
   on the shoulder of the drive roll.

2. When grooving, exert pressure on the pipe towards the operator (Figure 9).
   Do not attempt to groove any pieces of pipe shorter than 8″ (See Chart A). Increases risk of fingers being crushed in the grooving rolls.
   Do not reach inside of pipe. Keep hands away from sharp edges and burrs on end of pipe.

With Stabilizer

NOTE! Once stabilizer is adjusted for a selected pipe diameter and wall thickness, it does not have to be readjusted.

1.  Properly set up pipe to ensure pipe is level and square on the shoulder of the drive roll.
2.  Engage hydraulic pump and bring groove roll (upper roll) down until it contacts outside diameter of the pipe.
3. Tighten down stabilizer roll until roll contacts outside diameter of the pipe. Continue to tighten stabilizer one full turn after making contact on outside diameter of pipe (Figure 10).

Do not reach across pipe to adjust stabilizer.
NOTE! If pipe “walks off” of drive shaft during the roll grooving operation, the stabilizer will need to be further tightened 1/2 turn.
Do not use the pipe stabilizer on 8″ or short er workpieces. Increases risk of fingers being crushed in the grooving rolls.

Removing and Installing Groove Roll and Drive Shaft

NOTE! As groove dimensions are determined by the roll set geometry, specific roll sets are required when grooving the following:

•  2″ – 6″ Schedule 10, 40
• 8″ – 12″ Schedule 10, 8″ Schedule 40
• 2″ – 6″ Copper tubing (Types K, L, M, DWV)
• 1″ Schedule 10, 40
