12.1 OIL LEVEL CONTROL AND OIL CHANGE
Failure to maintain proper oil level will cause a drop in hydraulic pressure and loss of power cut.
We recommend changing the hydraulic oil at least once a year or immediately in the event that shows traces of oil
contamination. The recommended hydraulic oil and abrasion should be antifoaming and abrasion resistant, viscosity
grade VG46, SHELL TELLUS OIL 46, MOBIL DTE-25 or ESSO UNI POWER SQ-46.
Steps to follow:
1. Make sure the machine is unplugged from the power supply
.
2. Unscrew the oil plug and put the mouth under shear so that the oil falls by gravity. This has prepared a container
for collecting the oil
.
3. Once the oil stop falling out, tilt the machine back so that the remaining oil in the piston can get out too.
4. Now tilt the machine forward so that the oil containing the bomb can be released
.
5. Once the machine is empty completely, slowly fill in with new oil shear from the top hole filling which it was created
for this purpose
.
6. Put the cap slightly clenched.
7. Connect the hydraulic portable shear to the power supply to operate the machine so the piston makes its way about
three times
.
8. Disconnect the shearing machine and empty the oil following the steps 2 to 8.
9. Refill with new oil shear and put the oil plug again back.
.
Note: Dispose of hydraulic oil according to local regulations in your area. Never place in the sea, river, lakes and
sewage systems.
12.2 CHANGE OF BLADES
If any of the blades of the machine is damaged through use, you must change the cutting edge. To change
the cutting edge will have to loosen the screws that secure the blade with the supplied allen wrench, change the
cutting edge and re-tighten. (Remember that the blades have four cutting edges)
12.3 CARBON BRUSHES
Inspect carbon brushes once a month. The normal life of carbon brushes is 200 hours. Proceed to replace if the length
is less than 6mm
ATTENTION: The worn brushes will result in the loss of power, the engine overheat and damage the armour will be
irreparable
.To change carbon brushes proceed as follows:
1.
Unplug the unit from the mains supply.
