Operation
Securing the Pipe Bender
The JHPB-20 and JHPB-30 Hydraulic Pipe Bender
can be secured to the floor with three bolts through
the holes on the tripod pole bases if desired for
increased stability.
Direction of the Pipe Bender
The direction of the pipe bender can be adjusted by
pulling out the knob on the tripod seat (D
1
, D,
Fig. 3) and rotating the pump unit. When the knob
is released, the pipe bender can still be adjusted.
The machine can only be fixed in one position by
rotating the pipe bender until the position rod resets
into the indent in the base of the tripod seat.
When Using for the First Time
If the pipe bender is being used for the first time, be
sure to change the shipping plug on the top of the
pump unit (see Assembly Step 13) with the oil plug
in the hardware bag, which contains a vent hole on
the top. Failure to remove the shipping plug will
cause improper operation. The shipping plug
comes without the vent hole to prevent oil leakage
during the shipment.
To Bend A Pipe
Figure 5
To Bend a Pip
Referring to Figure 5:
1. Raise the handle (A).
2. Raise the upper wing plate (B).
3. Select the suitable bending die (C) for the pipe
to be bent and slip it on the end of the cylinder
ram (D).
4. Select the positions of the swaging blocks (E)
for the pipe. For shorter pipes, position the
swaging blocks closer together to account for
the pipe shortening during the bending
process.
5. Turn the swaging blocks (E) so the notch that
best fits the diameter of the pipe to be bent
faces in the direction of the bending die.
Note: Lubricating the swaging blocks will
promote ease of movement.
6. Place the pipe you are going to bend.
Note: Keeping the bending die (C) lubricated
will promote easy removal of pipe after the
bend is made.
7. Lower the upper wing plate (B).
8. Close the release valve (G) by turning clock-
wise.
9. Pump the handle (A) to bend the pipe.
Note: Applying heat to the pipe will promote
ease in bending.
When applying heat to the pipe,
the pipe must be free of oil and other flammable
material.
10. When the bend has been made, release the
pressure by opening the release valve (G). The
ram will automatically retreat.
