HYDRAULIC SYSTEM
A 5.5 KW motor drives a hydraulic pump, which supplies the power cylinders on each end of
the machine through regulation valves. The punch cylinder is directly connected to the punching unit,
where the shear cylinder is connected through a turning lever.
Hydraulic oil
For this purpose are advised the oil types indicated in the machine plate. The oil filling and
ventilation supports are located in the tank where access is provided after removal of the protection
having cooling cavities located on machine base.
Absorption filter
The oil filter should be checked every twelve months. Access to the filter can be ensured after
having dismantled the screws of the tank protection. If necessary the filter can be washed in paraffin.
Impurity section
After having taken out the lower machine body protection, the section located under the main
chassis should be checked each year for dirt and impurities.
Cleaning
Under normal operation conditions, all the visible working parts should be regularly cleaned
from foreign substances that can prevent a standard use of the machine.
