RIDGID 920 Roll Groover Instructional Video

the following is a video presentation on the proper use of the 9:20 roll groover it is designed to make the operation of your 9:20 roll groover easy and efficient the 920 roll groover is designed to form rolled grooves in steel stainless steel aluminum PVC pipe and copper tubing the hydraulic feeding of a grooving roll into the pipe that is supported by a drive roll forms the grooves the 920 roll groover includes three groove and driveshaft sets that can groove the following pipe two to six in schedule ten and forty eight to twelve in schedule ten and forty fourteen to sixteen inch standard 3/8 inch or standard wall with additional roll sets the groover can also be adapted to groove the following two to eight inch copper tubing types klm dwv 18 to 20 and schedule 10 wall 22 to 24 in schedule 10 wall see table tune your operators manual for exact wall thickness caution when properly used the 920 roll groover makes grooves that are dimensionally within the specifications of AWWA see 606 – 87 selection of the 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 temperatures should be completed caution 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 failure of the pipe warning before assembling or operating the 920 roll groover be sure to read the operator’s manual safety instructions including special instructions for electrical safety located in the front of the manual read and understand all the safety and operating instructions before operating the 920 roll groover read all warning labels on the tool for your convenience it is divided into the following segment so you can quickly find what you need installing the roll groover on the 300 power drive machine inspection machine set up operating instructions maintenance technical service installing the roll groover on the 300 power drive warning only use a rigid 300 power drive that operates at 38 rpm warning because of the groovers heavy weight to people are required to lift and set up the unit to remove the groover from the number 32 transport card remove the pin and slide the card from the base remove the hitch pins that lock the legs into the groover and remove the legs use two people to lift the groover onto the power drive slide the roll groover onto the support arms by aligning them with the tubes located on either side of the base warning while the roll groover base is on the power drive without the legs attached it is front heavy and could tip over push back on the tool head until the legs are in place and secure align the drive shaft so that the flats engage the jaws of the Chuck tighten the Chuck jaws securely onto the drive shaft by using repeated and forceful counterclockwise spins of the hand wheel lift each side of the groover and insert the legs into the sockets located in the base install the hitch pins adjust both legs until the unit is level check that the groover is level and the unit is stable warning the machine must be placed on a flat surface the 300 Powerdrive groover and pipe stands must be stable failure to locate the groover on a level surface or properly set up the unit may result in the unit tipping or the pipe falling install the pump handle by screwing it into the elbow machine inspection to prevent serious injury inspect your roll groover and power drive make sure the machine is unplugged and the directional switch is in the off position make sure the foot switch is present and attach to the machine inspect the power cord and plug for damage make sure the bolts holding

the roll groover and stabilizer to the base are tight make sure all screws holding the pump to the roll groover are tight check that the guard mounted to the roll groover is in place and operating properly warning do not operate the roll groover with the guard removed exposure to moving roll grooving rolls may result in fingers being crushed inspect the roll groover and machine for any broken missing or misaligned or binding parts as well as any other conditions which may affect the safe and normal operation of this equipment lubricating the roll groover is necessary according to the maintenance instructions use groover rolls and accessories that are designed for your roll groover and meet the needs of your application clean any oil grease or dirt from all equipment handles and controls inspect the groove rolls to ensure they are not damaged or worn machine setup pipe stands properly support pipe under pipe stands use pipe stands rated for the pipe size to be grooved note 6-inch pipe and smaller should be supported with a V j99 pipe Stan one stand for pipe less than 36 inches and two for greater than 36 inches in length six-inch pipe and larger can be supported on the rj 624 pipe stand one stand can be used for lengths less than eight feet when one stand is used the pipe should be centered on the stand so that the center of gravity of the pipe is over the center of the stand when it is about three feet away from the roll groover stabilizer adjustment the stabilizer has two different positions the position closest to the driveshaft will allow the stabilizer to work for two to sixteen inch pipe the second stabilizer position will work for fourteen to twenty-four inch pipe remove the two 3/8 inch bolts that hold the stabilizer in place with a 9/16 inch wrench or socket move the stabilizer into the desired position tighten the two 3/8 inch bolts that hold the stabilizer in place caution it is recommended that the stabilizer be used for all lengths of pipe setup make sure the machine is off position the foot switch so the operator can safely control the machine roll groover and workpiece plug the machine into the electrical outlet warning to avoid electrical shock and fires never use an extension cord that is damaged the cord must have a three prong plug and add sufficient wire thickness 14 gauge below 25 feet keep all electrical connections dry and off the ground check the unit to ensure it is operating properly by putting the switch to the forward position depress and hold the foot switch the Machine being used should rotate under at 38 rpm release the foot switch and turn the Machine off check that the groove rolls are the correct size roll guards warning do not operate the roll groover with the guards removed make sure the guards are operating properly and are not damaged exposure to moving grooving rolls or stabilize a wheel may result in fingers being crushed check that the upper grooving roll is fully retracted by placing the pump release lever in the return position towards the operator the guard should be in the open position as shown with pressure applied to the hydraulic cylinder and the upper role in the grooving position the guard should be in the closed or operating position the guard on the operators side will move in and out with the adjustment of the stabilizer operating instructions warning you should be thoroughly familiar with the proceeding safety information before attempting to operate this machine do not wear loose clothing or loose-fitting gloves when operating this machine keep sleeves and jackets buttoned always wear eye protection do not use this roll groover with a power drive that has a broken or missing foot switch always groove in the forward position keep hands away from the grooving roles and stabilizer wheel do not reach across the machine or pipe never reach inside the pipe never groove pipe shorter than what is recommended before making a groove the pipe must be properly prepared pipe ends should be cut square do not use a cutting torch pipe out of roundness should not exceed the total OD tolerance listed in the grooves specifications in your operator’s manual

see your operator’s manual for further details all internal or external well bends flash or seams must be ground flush at least two inches back from the pipe end do not cut flats on the gasket seat area the end of the pipe both inside and out must be cleaned of coarse scale dirt and other foreign material chart a in your operators manual list the minimum lengths of pipe or tubing to be grooved and the maximum length to be grooved with one v j99 pipe stand chart B lists the minimum length of the pipe or tubing to be grooved and the maximum length to be grooved with one rj 624 pipes and pipe or tube longer than the specified maximum lengths listed must be supported with two pipe stands warning failure to use two pipe stands may result in the unit tipping or the pipe falling make sure the stands and pipe are stable raise the upper groove roll housing by placing the pump release lever in the return position square the pipe and pipe support to the roll groover making sure the pipe is flush against the drive roll flange verify that the pipe is level or slope slightly upward away from the operator note if the machine cannot be leveled make sure that the slope of the pipe and the machine are the same caution if the pipe is grooved with the back end of the pipe to much higher than the end being grooved the pipe may not track and a pipe end flare may result check that the pipe is square with the drive shaft or tilted slightly away from the operator caution the tracking angle will affect the pipe end flare when the pipe end flare is excessive the left-to-right tracking angle must be kept to a minimum 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 or tube the groove depth gauge is designed to make a first guess of the depth required to achieve the required groove diameter make sure the pump valve is closed actuate the hand pump until the cylinder builds up about 500 psi of pressure put the correct section of the gauge under the adjusting nut tighten the adjusting screw onto the gauge back off the adjusting nut slightly and turn the gauge to the grooving position because of the significant variability in pipe outside diameter the depth setting gauge will not be 100% accurate in achieving the required groove diameter the actual groove diameter should be measured with calipers or a PI tape each turn of the adjusting screw will change the groove diameter by 0.1 hundredths of an inch see your operators manual for more details caution pipe wall thickness cannot exceed the maximum wall thickness specified in the pipe maximum and minimum wall thickness table in the operator’s manual flip the directional switch to forward and step on the power drive or threading machine foot switch while applying downward pressure on the 920 roll groover pump handle make sure that the groove roll has pressure on the pipe tighten the stabilizer until contact is made with the pipe plus 1 to 1 and 1/2 turns step on the foot switch and begin pumping use up to 5,000 psi for thin wall pipe and up to 6200 to 6,500 psi for standard wall pipe allow one full pipe rotation between quarter stroke of the pump handle after the depth of justing nut bottoms out on the unit allow the pipe to make 2 more complete revolutions to even out the groove retract the upper groove roll by placing the pump lever in the release position and release the foot switch note check the groove diameter with pipe tape adjust the depth as needed if flair is excessive use less pressure and slope the pipe downward as it goes away from the machine if the pipe tends to walk off the drive roll check the setup if correct increase the stabilizer pressure make sure the pipe is offset away from the operator make sure the pipe is sloped up away from the operator note as groove dimensions are determined by the roll set geometry specific roll sets are required when grooving the following to the 6-inch schedule 1048 to 12-inch scheduled 1040 14 to 16 inch standard wall 0.375

18 to 20 inch quarter inch wall 22 to 24 inch quarter inch wall 2 to 8 inch copper tubing types klm dwv to change Rolle said unplug the power cord on the 300 power drive loosen the Chuck on the 300 power drive but do not remove the gear set this will allow the drive shaft to spin freely so the stop pin can be engaged back off the number 1024 set screw in the upper roll housing with the long T handled hex wrench provided it may be necessary to lower the upper roll housing slightly by actuating the pump handle this will allow the guard to open enough to remove the upper roll shaft it may also be necessary to retract the stabilizer as much as possible guards should not be removed to change groov rolls lightly tap the upper groove roll shaft out of the upper roll housing until it clears the guards remove the upper groove roll shaft be sure to keep one hand solidly on the upper groove roll the groove upper roll weighs up to 14 pounds and could drop suddenly engage the locking pin in the drive shaft loosen the 5/8 inch draw bolt and remove the drive roll install the desired lower drive roll engage the locking pin in the drive shaft tighten the 5/8 inch draw bolt to approximately 150 foot-pounds install the matching upper groove role and shaft grease if necessary through the zircon the upper roll shaft it may be necessary to lightly tap the upper roll shaft in place make sure to align the set screw hole on the upper roll housing with the groove on the upper roll shaft tighten the number-10 24 set screw in the upper roll housing until it contacts the upper roll shaft tighten the Chuck on the 300 Power Drive removing the roll groover from the 300 power drive warning the cause of the groovers heavy weight to people are required to lift and remove the unit move the stabilizer to the position closest to the drive shaft remove the handle from the pump and set aside turn the lower legs counterclockwise to shorten the legs as much as possible lift up each side of the roll groover and remove each leg set the legs aside warning while the roll groover base is on the power drive without the legs attached it is front heavy and could tip over loosen the Chuck on the 300 power drive use two people to slide the roll groover off of the 300 power drive and place it upright on the ground insert the number 32 transport cart into the base make sure the two alignment lugs on the number 32 transport cart are also inserted into the base insert the hitch pin that holds the number 32 transport cart in place put both legs in the tubes used to support the roll groover when it is on the 300 power drive insert the hitch pins maintenance motor-driven equipment 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 groover equipment this machine can cause serious injury in the hands of untrained users make sure the machine is unplugged from a power source before performing maintenance or making any adjustments adding hydraulic fluid raise the upper groove roll housing by placing the pump release lever in the return position remove the pump handle from the pump assembly remove the pump from the lower roll housing rotate the pump 180 degrees so the filler cap is pointed up raise the pump as much as possible remove the filler cap and fill the reservoir with oil replace the filler cap put the pump back into its position on the lower roll housing tighten all fasteners holding

the pump in place lubrication lubricate with multi-purpose grease at the fittings located on the groove roll shaft and lower roll housing once a month and after every roll change
