INTRODUCTION
The Grinnell-10A grooving machine is a semi-automatic,
hydraulically operated machine. The machine is equipped for
roll grooving of steel pipe with a diameter between 25 and 200
mm (1" - 8") and a maximum wall thickness of 8 mm. Pipe
grooved with the Grinnell-10A grooving machine, and in
accordance with the specifications as mentioned in this manual,
is then suitable for Grinnell grooved type couplings. Fig 01: Protective cover.
GENERAL WARNING!
Although everything possible has been done to make the
Grinnell-10A as safe and user-friendly as possible, certain Fig 03: Shaft Cover.
areas of potential operator-hazard remain.
Never attempt to reach into the top- and bottom roll area whilst
grooving or whilst the rolls are rotating when the Grinnell-10A is
in operation.

1. Inspect the grooving machine before operating it. Check whether all parts, protective
covers and other safeties are in place, and mounted as described in this manual.
Checklist:
• 4 legs
• Tap out pin for removal of lower roll
• Depth gauge
• Lower roll 1"
• Lower roll 1¼" – 1½"
• Lower roll 2" - 6"
• Lower roll 8"
• Allen Key (4mm)
• Allen Key (5mm)
• Allen Key (10mm)
2. Make sure the machine is switched "OFF" before plugging in the unit. Always use the
foot-switch for operation.
3. Check the electric engine for exact power requirements. The Grinnell-10A comes with a
220V engine as a standard, but can be supplied with different voltages. Make sure a
proper connection is made by a qualified electrical engineer. Check if the machine is
connected to an internally grounded electrical system. Do NOT operate the machine in a
damp or wet environment.
4. Make sure that the machine is bolted down and fixed to the floor so that it can not be
moved while operating the machine, and is able to help support the weight of the pipe.
Warning! If the machine is not bolted down or fixed to the floor, it will cause a hazardous
situation, since the pipe may come loose of the machine during operation!
5. Pipe should be supported by a proper pipe-support. See page
4 for details. Pipe diameters exceeding 4”/100mm should be
supported with the side roll (See Fig 05). Do not attempt to
groove pieces of pipe with a length shorter than 200 mm (8").
Warning! Grooving pipe shorter than 200 mm will cause a
hazardous situation and can cause operational hazards.
6. When servicing the machine, or when changing roll sets,
always switch off the machine and disconnect the power cord.
7. Regularly service the machine and maintain it as described in
this manual, see page 8 and 9.
8. Do not attempt to groove pipe with a diameter of over 8"/200
mm or with a wall thickness exceeding 8 mm.
Warning! Grooving pipe exceeding wall thickness of 8mm will
cause a hazardous situation and can cause operational
hazards. Fig 05: Side Roll.
9. Make sure that clothing, gloves etc. stay well clear of the
rotating rolls when in operation at a minimum distance of 15
cm.
10. Do not operate the machine when not fully aware of its proper functioning, or when
feeling unable to operate the machine.
11. Wear protective gloves and shoes at all time, when operating the machine.
12. Make sure that the operating area is suited for the purpose. It should have proper
illuminations, be tidy and clean, and should not cause any hindrance when operating the
machine.
13. Only authorized and skilled personnel should operate the machine.

For ease of handling, the Grinnell-10A has a hoist point on the back of the machine, see
drawing on page 12. The total weight of the Grinnell-10A is approximately 100 Kg. Only lift the
machine with a hoist on this point.
Warning! Make sure the machine is fastened properly. Failure to do so may cause the
machine to drop from the hoist and cause hazardous situations for the operators. At no time
place yourself under the machine! Place the 4 legs under the grooving-table and secure them
in place. Make sure the bolts are properly tightened (use a torque wrench to reach 85Nm) and
check whether the legs are fixed in position.
Check the local power supply, and compare that with the machine you have just received.
Connect the correct power plug to the cable, and make sure it is suitable for the connection
on site. When connected properly, if switched on, the lower shaft and roll should rotate
counter-clockwise (see the arrow on the shaft cover showing the direction of rotation (Fig
06)).
Warning! All electric connections must be done by a qualified electrical engineer.
Check whether the proper roll set is mounted on the machine. If not, do not attempt to groove
a different pipe-size with a non-corresponding roll set. When needed, change the roll set
according to the steps as described in this manual.
Secure the Grinnell-10A grooving machine to the floor, making sure it is placed level.
Warning! An unstable machine is a potential hazard. It may cause the pipe to drop-off the
lower roll while grooving!
PIPE DETAILS
Make sure that pipe ends are square cut. Weld bead or seams (in- and outside) must be
ground flush with the pipe surface over a distance of 50 mm. Any dirt, scale, debris or other
ΧΡΥΣΑΦΙ∆ΗΣ Α.Ε.
foreign matter should be removed from the pipe ends since this may interfere with proper tool
operation.
PIPE SUPPORT
Any pipe-length exceeding 1.5 m (or shorter if so
required) must be supported by a proper pipe support.
It will prove necessary that large diameter pipe is
supported even when working with shorter lengths. Any
pipe length under 200 mm should not be grooved since
this may cause danger to the operator of the grooving
machine. When in doubt, contact your dealer or your
nearest Grinnell Sales & Distribution office. The pipe-
support must be placed just beyond one-half of the
pipe length from the tool. Pipe should be level with the
tool, or at a maximum of ½ ° below level.
The pipe support should be moved at around ½° to the right, when facing the tool. When
placed like this, the pipe will track properly
and will be held against the back-flange of the
lower roll.
Should the pipe-end start flaring (increasing
outside diameter) whilst grooving, the angle
that is used is too big, and should be reduced
(either the angle towards the machine or
towards the horizontal position). Pipes
exceeding the outside diameter of 4”/100mm
must be supported with the side roll. This
prevents the pipe for jumps and thumps
during the grooving process.
GROOVING OPERATIONS
Checklist before operating
Check whether the protective cover is in place. Always wear Fig 07: Main Switch.
safety-shoes and gloves when operating the Grinnell-10A.
Beware of loose clothing, ties, scarves etc.
ΧΡΥΣΑΦΙ∆ΗΣ Α.Ε.
Open the valve on the hydraulic hand pump. The upper-roll block will now come up. Rotate
and raise the adjustable stop and locking nut into top position. Now close the valve on the
hydraulic hand-pump (Fig 08). Make sure that the upper- and lower rolls are properly aligned.
If not aligned, the roll-set may be damaged. Check whether the proper roll set is mounted.
Whilst the pipe is rotating, apply more pressure by operating the hydraulic pump (Fig 14).
Apply pressure evenly and let the pipe make a full rotation after every stroke of the hydraulic
hand pump. Make sure that the pipe stays in full contact with the back-flange. Groove to full
depth as allowed by the adjustable stop. When this point is reached, stop applying pressure
and release the footswitch.
Open the valve on the hydraulic pump (Fig 08), the upper block and top roll will now be
released from the pipe.
ΧΡΥΣΑΦΙ∆ΗΣ Α.Ε.
Warning! Be careful, unsupported pipe will drop off the lower roll and can create a hazardous
situation.
Now remove the pipe. Carefully check and measure the groove
diameter. If the groove diameter is too big (groove too shallow) raise
the adjustable depth stop. By lowering the adjustable depth stop, the
groove diameter decreases (groove less deep). On the depth-stop,
each point is 0.1 mm. When needed, re-groove another piece of pipe,
until the proper dimensions are obtained.
During grooving, check the Grinnell-10A for proper operation. Check Fig 15: Measure the groove.
whether a possible pipe support is properly positioned, and inspect
the grooving area for possible loose pieces of pipe that may cause an obstruction.
CHANGING ROLL-SETS
SAFETY FIRST
Warning! Before changing a roll on the machine, or before any other handling or
maintenance is done, make sure that the power is disconnected and the main switch is in the
OFF position.
Check the roll-set mounted on the grooving machine. If incorrect, the roll set must be changed
to groove the pipe size needed.
Fig 18: Remove lower roll. Fig 19: Loosen the top roll.
ΧΡΥΣΑΦΙ∆ΗΣ Α.Ε.
Whilst holding the top roll, pull out the upper shaft. If the top roll is not supported it will fall out
the upper block. Now remove the top roll (Fig 21).
Before doing any maintenance or service, or before any other handling is done, make sure
that the power is disconnected and the main switch is in the OFF position.
At regular intervals, service the lubricating points on the grooving machine (Fig 25). Also,
lubricate the drive chain with lightweight grease every 100 hours and before any lengthy
storage. Any commercial/industrial lubricant can be used.
ΧΡΥΣΑΦΙ∆ΗΣ Α.Ε.
If the oil level is sufficient, increase the hydraulic pressure. This can
be done by removing the filler plug and inserting a screwdriver into the Fig 26: Filler plug oil reservoir.
hydraulic container. By turning the set screw the pressure can be
increased or decreased. Normal factory setting of hydraulic power
however, should enable you to groove pipe with a maximum wall
thickness.
When needed, always order original spare parts from your supplier.
Do not use other than original parts. If in doubt, contact Grinnell. For
proper and adequate repairs, always contact Grinnell for instruction.
Do not attempt to alter or adjust the machine without consulting
Grinnell.
