1.3. Description of the machine
The MC150B bending machine is a machine specifically designed for bending profiles, the majority of
which are metal, with different thicknesses and configurations, such as solid profiles, pipes, T-profiles, an-
gles...
The bending machine offers a set of standard tools, rollers, to allow the bending of profiles in a range of
shapes and sizes.
Apart from the standard rollers, the manufacturer also offers different types of additional rollers to produce
other types of bending, according to the configuration of the material to be handled, as well as specific roll-
ers for work with stainless steel or aluminium, manufactured with * SUSTARIN for jobs in stainless steel
or aluminum avoiding the material to be damaged or scratched.
* Sustarín: Polyoxymethylene, high resistance and high rigid crystalline thermoplastic, low friction and excellent dimensional stability
PRADA NARGESA S.L. is not liable for any damage that might occur due to misuse
or failure by users to comply with the safety standards.

1.6. Description of the guards
The gear motor and all the gears that allow the operation of the machine are located under the main upper
cover that protects the mechanisms.
Although the major mobile elements are protected by the upper cover, it is necessary to take special
precautions during bending operations in order to avoid entrapment between the rollers and the piece
being bent.

2. TRANSPORT AND STORAGE
2.1. Transport
There are two ways of carrying out the transportation of the machine:
- From the bottom, through the base of the machine, using a pallet jack or forklift as shown in the
illustration. Never raise the machine more than 200 mm from the surface in order to prevent the risk of
tipping
- From the top of the machine, from the anchor point designed for this purpose defined in figure 4, using a
crane or forklift .
Figure 4. Transportation of the machine
The design of the section bending machine MC150B allows the chassis inside the bench to reduce its
volume when transported. Picture 5 shows this arrangement.
Picture 5. Option for transporting the machine
WARNING: Before moving the machine it is essential to check that all screws fasting the chassis
of the section bending machine to the table, are properly tightened to prevent damage to the machine
and users who handle it.

2.2. Storage Conditions
The bending machine shouldn’t be stored in a place that does not meet the following requirements:
- Humidity between 30% and 95%
- Temperature of -25 °C to 55 °C or 75 °C for periods not exceeding 24hrs
(remember that these temperatures are in storage conditions)
- Machines or heavy objects should not be stacked on top

3. MAINTENANCE
3.1. General maintenance
- It is recommended to keep the piston rod clean, whenever possible, to ensure proper operation and to
extend its useful life.
- It is advisable to keep the friction rule lubricated along which the upper roller support slides. It is also
necessary to ensure a minimum lubrication of the inner walls along which the upper roller support slides.
In order to lubricate the moving parts of the machine that require lubrication, it’s recommended to follow the
next instructions:
- Clean the surface to be lubricated with a cotton cloth or a soft rag that does not release any threads. To
remove the accumulated grease and any possible residues that have become stuck to it.
- After cleaning, reapply grease onto the surface with the help of a rag or a spatula.
- Spread the grease evenly without creating excesses or clumps.
- Once the machine is lubricated, using the upper roller adjustment handle that controls the height of the
upper roller, raise this until it reaches its highest point.
- When the upper roller comes to its highest point, reverse the direction of the adjustment handle, to lower
the roller to its lowest point.
- It is recommended to keep the adjustment spindle of the upper roller lubricated as well as the adjustment
nuts to ensure a proper operation, avoid stiffness and extend its useful life.
- You need to at least try minimum greasing on the inner walls through which the support of the upper roller
moves.
- Repeat the operation to ensure proper lubrication of all spindles and guides of the upper roller support.
- Lubricate the machine on a regular basis according to its use.
CAUTION:
The "Emergency Stop" push button must be pressed and the machine brought to a stop in order to lubri-
cate the machine”.
