Machine Inspection
WARNING
Do not use this Roll Groover without a foot switch.
To prevent serious injury, inspect your Roll Groover.
The following inspection procedures should be per-
formed 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 roover and hy-
draulic pump to the base are tight.
5. Check that guard mounted to the roll groover is in
place (Figure 3).
Do not operate Roll roover with guard
removed. Exposure to moving grooving rolls may result
in fingers being crushed.
6. Inspect the Roll roover for any broken, missing,
misaligned or binding parts as well as any other con-
ditions which may affect the safe and normal oper -
ation of this equipment. If any of these conditions
are present, do not use the Roll roover until any
problem has been repaired.
WARNING

7. Lubricate the Roll roover if necessary according to
the Maintenance Instructions.
8. Use groover rolls and accessories that are designed
for your Roll roover and meet the needs of your ap-
plication. The correct groover tools and accessories
allow you to do the job successfully and safely. Ac -
cessories suitable for use with other equipment may
be hazardous when used with this Roll roover.
9. Clean any oil, grease or dirt from all equipment han-
dles 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 dam-
aged or worn. Worn groover rolls can lead to pipe
slippage and poor quality grooves.
Machine and Work Area Set-Up
WARNING
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.
• rounded 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 equip-
ment. 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 In -
structions 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 out-
doors.
• The cord has sufficient wire thickness (14 AW
below 25'/12AW 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 clock-
wise direction as you are facing the groover. Have
the machine serviced if it rotates in the wrong di-
rection or if the foot switch does not control its
stopping or starting.
• Depress and hold the foot switch. Inspect the mov-
ing 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.

1. Advance the upper groove roll by placing the pump re-
lease 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 (clock-
wise) until it stops against the top of the machine
(Figure 8).
3. Back the depth adjustment knob off one turn.
Figure 8 – Close-up of Depth Adjustment nob Being
Turned Down Against Top Casting
Forming the Roll Groove
Pipe wall thickness cannot exceed the max-
imum 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 be-
tween 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 con-
stant even downward pressure, pausing to allow
one pipe revolution per quarter stroke of the
pump handle.
3. When the depth adjustment knob contacts the ma-
chine 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 posi-
tion (toward operator).
5. Check groove diameter before proceeding with addi-
tional grooves.

Pressure Toward Operator
NOTE! roove diameter should be measured using a di-
ameter tape. To decrease groove diameter (in -
crease groove depth), rotate the index depth ad-
justment knob one mark counter-clockwise. To in -
crease 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 di-
mension (Figure 7).
2. If drive roll flange shaves pipe end, decrease offset di-
mension.
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 1/2degree offset di-
mension.
Grooving Short Lengths of ipe
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 stabi-
lizer.
NOTE! If pipe “walks off” of drive shaft during the roll
grooving operation, the stabilizer will need to be
further tightened 1/2turn.
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
• 11/4" - 11/2" Schedule 10, 40
Make sure machine is unplugged from
power source before changing the roll sets.
