2. Before connecting the pressure pipe to the system, start the pump for a few moments so that the air inside the pump is completely drained.
3. The pump shaft can rotate in two directions (left and right).
4. A suitable filter should be installed in the oil return circuit to the tank with a hole of 20 microns and cleaned every 500 working hours.
5. A suitable filter with a 125 micron hole should be installed at the head of the suction pipe inside the tank and cleaned every 500 working hours.
6. Install the air filter on the tank lid and clean it every 200 working hours.
