1. BEFORE USING THE EQUIPMENT AND SECURITY.
LARZEP hydraulic benders are designed and manufactured in accordance with internal quality standards, in compliance with the ISO 9001 regulation.
However, improper use may result in serious physical injury to the user, as well as in damage to the machine and the material being treated.
Never use hydraulic equipment that is damaged or suspected to be in poor condition.
The tools are designed for the applications described in this manual. Any other use may pose a risk to the equipment and result in hazardous situations for the
operator. The manufacturer accepts no responsibility for damage resulting from the improper use of the tool.
Do no store or leave the press where is can be accessed by the children.
The operator should be fully aware of the risks inherent in the use of high-pressure hydraulic tools, and should act responsibility in accordance with
that described in this manual, ensuring both his/her own safety as well as the safety of others located in the vicinity of the working zone.
El personal expuesto debe utilizar materiales de protección personal tales como botas, casco, gafas, guantes, ropa... y conocer las normas aplicables sobre prevención
y medioambiente.
Boots Helmet Glasses Gloves Clothes
Never modify the tool or add elements that may affect its safety, without express authorisation from the manufacturer.

1- There are not operators standing around dangerous area.
2- Ensure that the equipment it’s located over firm ground.
3- Do not work around dangerous area.
4- The commands have been operated with the hands.
5- Damaged or dirtied connections or coupler.
6- The flexible hydraulic hoses are not twisted.
7- The commands are in neutral position.
Check that the working pressure is less than the 80% of nominal capacity
Specialist personnel should only carry out repairs and maintenance operations, etc. Always use original LARZEP spare parts.
Carry out maintenance operations on a regular basis, as indicated in this manual.
Once you have finished using the tool, disconnect it, clean it and store it in a clean, safe place.

3. START UP.
The bender is packed in a sturdy wooden box, which protects it from the knock damage throughout the transportation. Once the tool is used, clean it and
keep it into the box, to be stored until next usage.
Unpack the equipment assuring that all the parts indicated in the drawing provided in the manual are found and the material has not been damaged.
The hydraulic part is provided threaded to the structure plate of the grounds. Mount in this plate the lower and upper grounds. (Stick with the tube
measures up faced) with the axles and clips. Checking that the upper ground tilts free.
In model VB1227, assemble the tripod by screwing the coupling into the support plate and inserting it into the tripod shaft.

1. Connect the pump to the cylinder
via the hose and the quick plug. 1. Connect the electric pump to the
cylinder via the hose and the quick plug. 1. This model does not require
any type of hydraulic connection. 1. This model does not require any type
of hydraulic connection.
2. Enable a few pump strokes using
the lever with the screw slightly
loose (turn anticlockwise) in order to
bleed the circuit.
2. Replace the electric pump’s transport
plug with its operating plug. 2. Enable a few pump strokes
using the lever with the screw
slightly loose (turn anticlockwise)
in order to bleed the circuit.
2. Enable a few pump strokes using the

3. Tighten the screw manually (turn
clockwise). 3. Make sure that the voltage in the mains
corresponds to that required by the
machine and that the motor rotates in the
direction indicated by the arrow.
3. Tighten the screw manually
(turn clockwise). 3. Tighten the screw manually (turn

the switch in order to start the motor.
4. When you pump now, the jack
piston will move forward. 4. When you pump now, the jack piston
will move forward.
5. When the screw is loosened once
again, the piston moves back due to
the action of an internal spring.
5. Alter making sure that the working
zone is unoccupied and all the elements
are fixed in place moves the distributor
lever to its open position by turning 90º.
The cylinder piston will move forward.

once again, the piston moves back
due to the action of an internal
spring.
5. When the screw is loosened once
again, the piston moves back due to the
action of an internal spring.
6. When the lever is moved back to its
tank position, the piston will move back
due to the pressure applied by the cylinder
spring.
BENDING OPERATION
Once you know the dimensions of the pipe you need to bend, proceed as follows:
1. Lift the upper template so that it is vertical. (1)
2. Place the shafts in the corresponding holes in accordance with the pipe dimensions, as indicated on the chart.
3. Place the shafts rollers in the position corresponding to the pipe to be bent. See the makings on the rollers.
4. Place the bender corresponding to the pipe on the protruding end of the piston.
5. Close the upper template, thereby fixing all elements in place.
6. Insert the pipe to be bent in one side, between the two templates. Be careful not to rotate the rollers out of their correct position and make sure that the
bender stays on the end of the piston. (2)
7. Activate the hydraulic element as described in the previous section.
8. Move the piston out as far as necessary in order to achieve the desired curve angle, bearing in mind the elasticity of the pipe at all times. (3)
9. Depressurise the hydraulic element, the piston will move back in releasing the pipe.
10. Lift the template and remove the pipe. The bender will normally remain attached to the pipe. Use a plastic mallet to separate them. (4)

4. MAINTENANCE.
1. Depressurise the system and disconnect the hydraulic and electric elements before carrying out any maintenance operations.
2. Always use original LARZEP, S.A. spare parts.
3. Whenever you use the machine, visually check the oil level and inspect for damage to the hydraulic element (piston scratched, threads, leaks, etc.) and
make sure all the accessories are in perfect working order (hose, quick plug, etc.)
4. Clean the machine after every use and lubricate the critical zones: threads, shafts, inside of the rollers, piston, etc. before storing in its wooden box.
5. In event of heavy duty use, change the hoses and plug regularly, even if they appear undamaged to the naked eye.
6. Regularly replace the hydraulic oil in the tank with clean oil (at least once a year). Always use LARZEP, S.A. oil.
7. Maintenance or repair operations that require the disassembly of the machine’s mechanical parts (jack, cylinder or pump) should only be carried out by
specialist personnel.
