HK-1｜Hydraulic Oil Replenishment

    Before supplementing hydraulic oil, please read the notes at the end of this article or in the instruction in detail.

    Only when the adjusting screw has been turned clockwise to the end, the distance of the spoon pushing out is still not enough, hydraulic oil replenishment is necessary.

    Adding 46 # Hydraulic Oil

    • 1. Secure the lever and wrap a tissue or cotton cloth around the oil port.

    • 2. Stand the machine on its side with the oil port facing upwards and turn counterclockwise to open the adjustment screw.

    • 3. Fill with a tool with a needle or thin hose, insert the tube into the bottom of the screw hole in the oil port and slowly fill.

    • 4. After adding an appropriate amount of hydraulic oil, rotate the adjusting screw to tighten the sealing ring to the edge of the oil port. lightly close the lever to completely exhaust the air in the oil port, and adjust the spoon to the appropriate pushing distance according to the “Push Spoon Distance Adjustment”

    • 5. If the hydraulic oil is added excessively, the adjusting screw sealing ring can be retracted to the edge of the oil port, and lightly close the lever to to overflow redundant hydraulic oil. Then repeat steps 4 and 5 until the adjusting screw is closed normally and the push distance of the spoon is adjusted to the appropriate distance.

    Note

    • Ensure that the lever is fixed before removing the adjustment screw! Prevent touching the oil cylinder during refilling.
    • Surround the oil port with paper towels or cotton cloth to prevent spilled oil from contaminating the machine
    • There should be no air left in the oil cylinder. It is necessary to lightly close the handle to allow the oil to slightly overflow from the oil port to ensure that the internal air is completely discharged.
    • Be careful to prevent the machine from tipping when adjusting screws are not installed.
    • Excessive pressure on the lever may cause hydraulic oil splashing
