FILL AND VENT PROCEDURES FOR HPS, HPI, HPT and HZ

 HPS HPI AND HPT SERIES FILL ONLY PROCEDURE

  1. Maintain air pressure to B1 and B2 ports. (Cylinder retracted) Air pressure at 60 psi. minimum.
  2. Air pressure on fill unit set at 40 psi.
  3. On the fill unit coupling, depress the inner ring which will open the coupling. Using a catch can, depress the palm button on the fill unit until all the air is removed from the fill unit hose. Pull back on the coupling to close.
  4. Attach the fill unit to the cylinder. (black dust cap is the fill coupling)
  5. Depress the palm button on the fill unit (can use light object to hold down palm button). Watch the level of oil in the fill unit decrease.
  6. When you no longer see the oil depleting in the fill unit, release the palm button on the fill unit and wait until the exhausting air depletes.  If you overfill the cylinder (work rod extended), simply wait for the rod to retract until the level of oil stops rising. Cylinder will purge itself of any extra oil.
  7. Remove the fill unit from the cylinder. Procedure complete.

HPS SERIES FILL AND VENT PROCEDURE

  1. Maintain air pressure to B1 and B2 ports. (cylinder retracted) Air pressure at 60 psi. minimum.
  2. Air pressure on fill unit set at 40 psi.
  3. On the fill unit coupling, depress the inner ring which will open the coupling. Using a catch can, continue pressing the palm button on the fill unit (can use light object to hold down palm button) until all the air is removed from the fill unit. Pull back on the coupling to close.
  4. Attach the fill unit to the cylinder. ( black dust cap is the fill coupling)
  5. Loosen the #2 SAE plug slightly on the top on the work section and booster. Do not remove. Remember, the cylinder has air pressure! You just want to loosen the o-ring.
  6. Continue pressing palm button.
  7. Oil and any air will begin to purge or bubble out of the plugs. When you no longer see air coming out, close the plugs while continuing to press the palm button on the fill unit.
  8. When you no longer see the oil depleting in the fill unit, stop pressing the palm button on the fill unit and wait until the exhausting air dissipates. If you overfill the cylinder (work rod extended), simply wait for the rod to retract and you don’t see any increase in the oil level in the fill unit. It will purge itself of any extra oil.
  9. Remove the fill unit from the cylinder. Procedure complete 

HPT SERIES FILL AND VENT PROCEDURE

  1. Maintain air pressure to B1 and B2 ports. (cylinder retracted) Air pressure at 60 psi. minimum.
  2. Air pressure on fill unit set at 40 psi.
  3. On the fill unit coupling, depress the inner ring which will open the coupling. Using a catch can, press the palm button on the fill unit (can use light object to hold down palm button) until all the air is removed from the fill unit. Pull back on the coupling to close.
  4. Attach the fill unit to the cylinder. ( black dust cap is the fill coupling)
  5. Loosen the #10 SAE plug on the side on the work section cap. (opp. end of the work rod). Do not remove. Remember, the cylinder has air pressure! You just want to loosen the o-ring.
  6. Continue pressing the palm button on the fill unit. 
  7. Oil and any air will begin to purge out of the plug. When you no longer see air or bubbles coming out, close the plug while continuing to press the palm button on the fill unit.
  8. When you no longer see the oil depleting in the fill unit, release the palm button on the fill unit and wait until the exhausting air depletes. If you overfill the cylinder (work rod extended), simply wait for the rod to retract and you don’t see any increase in the oil level in the fill unit. It will purge itself of any extra oil.
  9. Remove the fill unit from the cylinder. Procedure complete 

HPI SERIES FILL AND VENT PROCEDURE

  1. Maintain air pressure to B1 and B2 ports. (cylinder retracted) Air pressure at 60 psi. min.
  2. Air pressure on fill unit set at 40 psi.
  3. Apply air pressure to A1 port, exhausting B1. Cylinder will extend. Hold
  4. Attach the fill unit hose to the cylinder (black dust cap is the fill coupling). The cylinder will push out the extra 30% oil and any air in the cylinder back into the fill unit hose.
  5. When the movement of oil/air stops, cylinder is empty. Remove the fill unit and then retract the cylinder with air pressure to B1, exhausting A1.
  6. On the fill unit coupling, depress the inner ring which will open the coupling. Using a catch can, press the palm button on the fill unit until all the air is removed from the fill unit hose. Pull back on the coupling to close. Attach to the cylinder’s fill coupling, (black rubber cap)  
  7. When you no longer see the oil depleting in the fill unit, stop pressing the palm button and wait until the exhausting air dissipates. If you over-fill the cylinder (work rod extended), simply wait for the rod to retract until there is no increase in the oil level on the fill unit. The cylinder will purge itself of any extra oil.
  8. Remove the fill unit from the cylinder. 
  9. Repeat steps 3 thru. 10 until no air is noticed when purged from the cylinder into the fill unit. When no air left in cylinder, procedure is complete.

HZ SERIES FILL AND VENT PROCEDURE

  1. Apply air to the “B2” port on the Hypercyl, retracting the unit to its home position.
  2. Disconnect the fill unit hose from the fill unit and with one end of the hose in a catch can, attached it to the fill nipple (FC-1). All oil and internal air should exit the unit through the hose.
  3. Reattach the fill unit hose to the fill unit and depress the inner ring on the fill coupler (FC-2). With the end of the hose in a catch can, pump the handle until you have purged all air from the fill unit hose. Once all air has exited the hose, pull back on the coupler sleeve.
  4. Eliminate all air pressure from the port on the Hypercyl. Attach the fill unit hose to the fill nipple and begin pumping the handle unit you have reached the appropriate ‘WF” dimension (distance from bottom of flange to rod end) listed below. (Repeat steps 1 thru 4 until you have purged all air from cylinder.)
  5. Disconnect hose from the Hypercyl and the process is complete!

“WF” Dimension refers to distance from the bottom of the head (black plate with rod protruding) to the bottom of the stock work rod. See HZ Spec sheet for more details.

For 1, 2, 4 and 8 ton units    “WF” = 1.50’’
For 10, 15 and 20 ton units  “WF” = 1.75’’
