1. Securely tighten the valve. Make sure oil has been applied to the supporting rollers, moulds
and the pipes to be bent.
2. Choose the correct size bending mould for the pipe to be bent and fix to the top of the pump
stem. The slots of the two supporting rollers should face the relevant assembling holes of
the upper and lower plates. This eliminates the possibility of assembling the rollers and
moulds incorrectly and therefore damaging them.
3. When the pipe to be bent is positioned in place, close the upper plate. Operate the
hand pump to bend the pipe. Once complete push the valve and the piston will reset
automatically. Open the upper plate and take out the bent pipe.

1. Before use, make sure to fill the oil tank with oil.
2. Before bending pipes, the valve should be closed tightly, otherwise the pressure will not
increase. Loosen the screw of the oil nozzle so air can circulate in the oil tank.
3. The diameter of the pipe to be bent should be similar to the mould in use, otherwise the
pipe will be deformed and you will damage the mould.
4. Pipes that have welded seams should not be face to the mould directly.
5. During the bending process the two supporting rollers should roll in tandem while the
pipe is moving within the slot of the mould. If only one roller is working, stop operation
immediately
6. Make sure to clean the pipe bender periodically and when adding new oil, an appropriate
filter must be used. Machine oil to be used by the pipe bender is #15.

TROUBLE CAUSES SOLUTIONS
The pushing rod moves
unsteadily after the
piston has extended with
using the handle
The screw of oil nozzle has not been loosened Loosen the screw of the oil nozzle
The oil outlet valve on the pump is not sealed correctly or the
steel ball of the oil outlet valve is not round and smooth
Oil is dirty. Clean the oil and change the steel
ball.
The oil leaks at the ends
of the piston stems of
both large and small
pumps
The seal rings are damaged Replace them with the spare parts in the
bags supplied
Oil leakage at the pump The inner pressure ring has been loosened After dismantling the limit screw and the
valve tighten the pressure ring
Pushing force of the stem
is low
Incorrect sealing of the steel ball within the valve Change the steel ball
The steel ball has not been clamped tightly on the . Tighten the valve or if no steel ball exists
add a steel ball to the .

TROUBLE CAUSES SOLUTIONS
Oil leak appears at the
top side of the pushing
stem
The seal ring at the top side of the pushing stem
has been damaged Replace the O ring 14 x 2.4 (not supplied)
Insucient oil suction
from the large and small
pumps
Lack of oil or grit has gathered in the oil filter Dismantle the oil draining valve and clean it. Fill the
tank with oil
The assembling hole of
the mould is cracked
One side of the mould has a greater load force
while being pushed out.
Check if the positions of the two supporting rollers are
the same. Put some oil on the surfaces of supporting
rollers and the pipe to be bent.
Abnormal rest of the
pump stem The ball at the outlet valve cannot release
Extend the piston( No. 7). When force has been applied
to the piston pump, strike the handle seat with a
hammer several times, the steel ball will be reset.
