The guidelines below apply to all AceCo tools- finger joint, moulder, planer, hydraulic cartridges and saw collars- that are retained with hydraulic clamping.

Verify that the machine has been powered down and is LOCKED OUTand TAGGED OUT anytime a head is to be removed/installed, pressure checked or inspected.

  1. At the beginning of each shift (more often in extreme operating conditions), check head pressure using a calibrated grease gun.
  2. Inspect head for grease seepage around sleeve and inlet/relief fittings when checking head pressure. If any seepage is detected, do not run the head.
  3. Never leave an unpressurized head installed on a spindle.
  4. Do not exceed maximum pressures stamped on the head.
  5. Never install or pressurize a head that is not properly sized for the spindle.
  6. Never install an Ace-Loc head on a keyed spindle that had not been fitted with a specially hardened sleeve. The standard sleeve could deform around the keyway and render the head unusable.
  7. Clean the machine spindle with a shop towel and solvent, alcohol or acetone to remove oil and dirt before removing or installing the head on the spindle. Inspect spindle diameter, in 3 locations, on a regular basis.
  8. Remove any burrs or embedded debris from the spindle with a honing stone. Do not use emery cloth with the spindle running. This will eventually reduce the spindle diameter and could compromise the clamping ability of the hydraulic sleeve in the head. Remove any burrs with a small fine grit honing stone and oil.
  9. Inspect the internal bore of the head for damage, burrs or embedded foreign matter. Any burrs or embedded material can be removed using a small round honing stone. Do not use emery cloth on a split dowel or brake/ball hone and drill to remove burrs. This will remove excessive material and could compromise the clamping ability of the hydraulic sleeve in the head.
  10. Always use a lock collar on hydraulic tooling.
  11. AceCo recommends BLADE CLEAN brand cleaner when cleaning Ace-Loc heads. Using the wrong chemicals can deteriorate the o-rings.
  12. Insure that the pressure relief valve is closed before soaking the head in cleaner.
  13. Use only NLGI 2 rated grease when pressurizing the heads.
  14. Always lift and carry hydraulic heads. Do not slide across any surface. Damage to the bottom of the hydraulic sleeve may result.
  15. Always use anti-seize compound on all bolt threads, washers and nuts before torqueing. Insure that the proper grease fitting is used when being replaced.  There are two industry standards- 1/8”-27 NPT and 10mm. Although the two threads are similar in size and will fit in the opening, they cannot be interchanged. Installation of the wrong fitting will result in a mismatch of the threads, compromising the ability to form the proper seal.
  16. Never sandblast heads or cutters. Damage will result.
