OPERATION
PURGING OIL TANK
Check the hydraulic oil in the cylinder by loosening the vented oil bolt
(Fig. 1) and visually ensure that the piston inside is covered in oil when
the pipe bender is in the horizontal position.
Purge the tank before operating or if the response is slow after pumping
the handle.
1.
Loosen the vented oil bolt (#46) if air is in the pump.
2.
Raise the cylinder head to make the pipe bending machine tilt at
a 45° position.
3.
Press down the handle (#2) until there is no air in the cylinder.
4.
Once the air is removed, tighten the oil bolt and loosen the
release valve counterclockwise. The cylinder ram will return to
its original position.
5.
Lower the cylinder head back to a horizontal position.
PIPE BENDER OPERATION
1.
Tighten the release valve (#26) by turning clockwise.
2.
Loosen the vented oil bolt (#46).
3.
Grease die cover (#56), swaging blocks (#68) and the pipe to
be bent.
4.
Lift the upper plate (#54) and affix the bending die to the end of
the cylinder ram (Fig. 2). Place two swaging blocks into the
holes of lower plate (#64) and place pipe in front of them. Turn
the swaging blocks so their grooves face toward the pipe die
(Fig. 3).
5.
To account for the pipe shortening during the bending process,
make sure the pipe extends beyond the swaging blocks (Fig. 3).
6.
Set the swaging blocks closer together for short pipes (Fig. 4),
to ensure that the pipe extends beyond the swaging blocks to
account for pipe shortening during the bend.
7.
Return upper plate to original position and use the advance
pump (Fig. 5) to quickly advance the die. Note: Only one handle
is included with the bending machine. The picture below shows a
piece of pipe being used as a handle in the advance pump.
8.
Use the forming pump to apply heavy pressure to bend the pipe to its
desired angle.
9.
When finished bending, release the pressure by opening the release
valve. The ram will automatically retreat. Lift the upper plate to take
out the bent pipe.
