Step 3: Lift the hand shank of the manual valve, turn on to press. There must be a person when the main engine boosts. When reaching 55Mpa, it stops.
Step 4: When the pressure drops to 45MPa, the electric controlling system will turn on itself and the pressure will rise back. When there is no oil exuding, then finish the pressing.
Step 5: Turn off, press the hank shank downward to make the squeezing tank away 10mm. Then lift the hand shank and open the top plate.
