Adjusting Roll Groove Depth
Note: Due to differing pipe characteristics, a test groove should always be
made when setting up or changing pipe sizes. The index depth adjustment
knob must be reset for each diameter of pipe/tube.
915
1. Tighten depth adjustment to fi x groover on pipe. Do not overtighten.
2. Set depth adjustment screw (Fig. 33) to give correct depth (see Fig 34).
916
1. Lift feed handle.
2. Fully loosen depth adjustment screw.
3. Tighten depth adjustment screw as shown in Fig. 16.
4. Back off depth adjustment knob as shown in chart.
918, 918I
1. Advance the upper groove roll by placing the pump release lever in
"ADVANCE" position (away from operator) and pump the handle until the
upper roll contacts the outside diameter of the pipe to be grooved.
2. Turn down the indexed depth adjustment knob (clockwise) until it stops
against the top of the machine (Fig. 17).
3. Back off the depth adjustment knob (Fig. 18).
Forming the Groove Roll
915
1. Rotate depth adjustment by approximately one revolution.
2. Move ratchet to rotation socket and turn to advance 915 around pipe.
3. Stop after one revolution and repeat steps 1 and 2 until depth stop is
reached.
4. Check depth of groove and adjust depth stop as required. Further
grooves with the same pipe will be made to the same depth.
5. Loosen feed screw to open the 915.
916, 918, 918I
1. Press on footswitch to start machine and apply a steady pressure to the
feed handle/hydraulic pump handle.
2. Keep pressure on pipe with right hand to prevent pipe being fed out of
the rolls.
3. Continue applying a steady pressure until groove depth stop is reached.
4. Do not over-feed. Allow one full revolution before increasing pressure on
rolls to prevent overload.
5. Stop machine and check depth of groove. Adjust depth stop as required.
Further grooves with the same pipe will be made to the same depth.
6. Raise handle (916) or release pressure (918) and remove pipe.
Always check the completed groove with a fi tting before installation.
Pipe Stabilizer/Nipple Bracket
This stabiliser is designed to work on 2 1/8"- 12" pipe. It can only be mounted
on 300 power drive and 918I bases that have the 3 mounting holes.
1. Align bracket on mounting holes (Fig. 19 - a, b).
2. Install and tighten bolts.
3. With pipe correctly positioned tighten stabiliser roll until it contacts the
pipe. Tighten one further turn (Fig. 20).
Warning: Do not use for lengths of pipe shorter than 8".

(Fig. 26).
2. Remove groove roll shaft and groove roll (Fig. 27).
3. Lock spindle and remove retaining nut (Fig. 28).
4. Remove drive shaft (Fig. 29).
5. Install new drive shaft.
6. Lock spindle and tighten retaining nut (Fig. 30).
Changing Grooving Roll Sets 1", 1 1/4"-1 1/2"
1. Perform steps 1-6 above with the appropriate drive shaft.
2. Tighten draw bolt (Fig. 31).
