AceCo hydraulic tools (finger joint, moulder, planer and saw collars) are manufactured to very precise tolerances. Although the tools are made from very high quality hardened steel, they         are not indestructible.If the tool will not easily slip onto the spindle – STOP and investigate.   DO NOT force the tool down onto the spindle with a hammer.

Installation

            Machine:

1)     Verify that the machine has been powered down and is LOCKED OUTand TAGGED OUT.

2)     Clean the machine spindle with a shop towel and solvent, alcohol or acetone to remove oil and dirt.

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.

3)     Measure the spindle with a micrometer at the top, the middle and bottom at 90-degree intervals. Record the measurements. Total clearance between the spindle and the bore of the head cannot exceed .003” (.076mm) for keyless spindles. Clearance for keyed shafts cannot exceed .002” (.050mm).

EXAMPLES: If the nominal diameter of the spindle is 1.8125”, the spindle diameter of a keyless shaft should be no less than 1.8095” or 1.8105” for a keyed shaft.

If the nominal diameter of the spindle is 1.5000”, the spindle diameter of a keyless shaft should be no less than 1.4970” or 1.4980” for a keyed shaft.

4)     If the spindle is of proper diameter, wipe off spindle one final time with a clean shop towel.

Head:

1)     Clean the internal bore and the bottom of the head to remove any oil and dirt.

2)     Note the pressure recommendation on the flange of the sleeve.

3)     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.

4)     Clean the internal bore of the head one final time and set the head on a clean surface.

5)     Open the pressure release valve to relieve any residual grease pressure that may be have built up due to an increase in temperature.

6)     Lift the head and gently position on top of the spindle. Slowly lower the head in a rotating motion to help align the internal bore of the head with the spindle. Do not drop the head.If the head does not freely seat on the bottom flange of the spindle, Stopand remove the head from the spindle. Do not force the head downward on the spindle- damage to the head and spindle will result.

7)     If a bottom lock collar is used, rotate the head until the lock collar pins engage in the receptacles on the bottom of the head.

8)     Close the pressure release valve with the correct size allen wrench. Do not over tighten. Using a too small allen wrench will eventually round out the set screw and the valve will become inoperable and need to be replaced.

5)     Clean the inlet fitting on the head and the hydraulic coupling on the end of the grease gun hose before mating the two. Dirt on the fitting or coupling could be pumped into the head, preventing the inlet valve from sealing properly, causing a slow loss of pressure and eventual head failure during operation.

6)     Pressurize the head to the specified value. You will find the correct value stenciled into the flange of the sleeve.

7)      Release the hose pressure and remove the hose from the head.

8)      Clean any excess grease from around the inlet and pressure release valve with a Q-Tip (cotton swab).

9)      Install top lock collar and tighten.

Removal

1)     Verify that the machine has been powered down and is LOCKED OUTand TAGGED OUT.

2)     Clean any exposed spindle area above the head to remove any dirt or foreign matter.

3)     Remove top lock collar.

4)     Release pressure by opening release valve with the correct allen wrench.

5)     Lift head slowly, straight up.

6)     Place on a clean, smooth surface.
