5. Operating Instructions
1. Operating the pump
1) Check that the hydraulic pump valve is in the
ON position. (Fig. 15)
2) Lift the pump handle firmly in one go and
the upper roller will be lowered onto the
pipe. (Instant drop) (Fig. 16)
3) Keep lifting the pump handle up and down
until you have finished processing the pipe.
The upper roller will gradually press deeper
into the pipe to create a groove. (Fig. 16)
4) When you set the hydraulic pump valve to
OFF, the upper roller will return to its resting
position. (Fig. 15)
2. Adjusting Groove Depth
1) Loosen the hydraulic pump valve, and pull
the pump handle up firmly to engage the
upper roller lightly with the pipe. (Fig. 17)
2) Place the spacer on the upper surface of the
cylinder and lightly tighten the adjusting
nut. (Fig. 18)
* Hold the spacer in position so that the
thickness matches the size of the pipe you
are working on. (Fig. 20)
* The spacer is used as a reference when
adjusting groove depth. After an initial trial,
use the adjusting nut to fine-tune to the
appropriate groove depth.
* If the groove is too shallow, turn the adjusting
nut anti-clockwise to increase the depth of
the groove. Conversely, turn the nut
clockwise to make the groove shallower.
* One sub-division of the larger divisions on the
adjusting nut is equivalent to approximately
0.3 mm. (Fig. 19)
3. Loosen the hydraulic valve and remove the
spacer from the cylinder.
