Operation
•
Read the entire section of the safety instructions at the beginning of this manual, including all
relevant information.
•
Check the tool for damaged, loose and missing parts before use. If any problems are found,
do not use the tool.
•
Note:
You may want to practice using the tube bending machine on scrap parts first.
IMPORTANT! Check the correct level of hydraulic oil in the jack before using the machine
for the first time. Also check that the unit is functioning properly. If it does not work,
remove air from the hydraulic system according to the instructions.
Remove excess air from the hydraulic system
1. Open the exhaust valve.
2. Remove the oil filler plug and fill the jack with hydraulic oil to the full level.
3. Exert pressure on the saddle and pump the handle several times quickly.
4. Check the oil filling opening and top up the oil filling opening with hydraulic oil if necessary.
5. Replace the oil filler plug and close the drain valve.
The pipe bending machine is designed to bend water pipes and heavily galvanized pipes. With thin-
walled pipes, you may have problems with kinks or folds. To prevent this, fill the pipe with sand and
close both ends before bending.
1. Always use this pipe bending machine only in the upright position. Make sure that there is enough
space on all sides of the pipe bending machine for the length of the pipe you want to bend.
2. Place the machine on a firm, level, even surface that can support the weight of the pipe bending
machine. When used on a workbench, we recommend screwing or clamping the machine.
3. Select the bending die that corresponds to the size of the pipe you want to bend. Place the selected
bending die on the bottle holder.
4. The rollers must be adjusted so that the top of the pipe to be bent presses against the bottom of the
rollers. The pipe can be bent from a flat curve to a 90° angle.
Adjusting the rollers
1. Remove the pins of the two roller rails and slide the roller rails out of the rollers and release
the rollers from the frame.
2. Place the pipe to be bent on the die and determine where to place the pipe at the holes in the
frame.
3. Remove the pipe.
4. Hold one of the rollers over the selected hole and fix it with the pin. Repeat this procedure for
the remaining roller and for the roller rails.
General operation
1. Push the pipe that you want to bend through the pipe bender between the die and the rollers.
2. Tighten the outlet valve on the bottle lifter with the slotted end of the handle clockwise.
3. Insert the handle into the pump sleeve and pump it up and down to lift the jack and bend the
pipe.
4. When the tube has been bent to the desired angle, remove the handle from the jack.
5. Loosen the valve loosening screw one full turn (counter-clockwise). This loosens the pipe and
makes it easy to remove.
