A. 4 AND 6 POINT CRADLE TO SCALE ASSEMBLY
Lifter Models: HML400 & HPL402
Scale Model Number: 59011A
Tools Required (Figure 3):
• 5/16" Allen Wrench
• Needle Nose Pliers
• Screw Driver– Phillips
Assembly Instructions:
1. Disassemble cradle after removing from lifter.
2. Disassemble the scale's hanger post (Figure 4).
a. Using the screw driver and pliers, remove the retainer screw in the load cell.
b. Using the 5/16" allen wrench, remove the sleeve bolt and sleeve from the
scale.
3. Place the scale's sleeve into the lifter cradle (Figure 5).
a. Use the new sleeve bearing washer that is already supplied on the scale
sleeve. Make sure the old sleeve-bearing washer is removed.
b. Place the bolt and lock washer back into sleeve.
4. Connect the scale to cradle.
a. With the sleeve bolt in hand, take the scale in the other hand, and position
the bottom load cell threads over the bolt and start turning in (Figure 6).
Critical: There is a mill slot on the load cell and two smaller slots on the
sleeve. Position the sleeve so it fits into the slot. They MUST mate. Once
aligned, turn in the sleeve bolt with Allen wrench. Completely turn in the
bolt so the lock washer is fully compressed. Sugg
estion: For ease of handling, place cradle with scale on flat surface (i.e. table top) and align lift
holes to scale.
5. Install the retainer bolt. A 1/8" hole has been drilled through the load cell and
the sleeve bolt. The retainer screw must go through both. Look into the load cell
and use the Allen wrench to align the holes. Once aligned, install the retainer
bolt. It should go in cleanly. Tighten the nut accordingly (Figure 7).
6. Do a final inspection.
a. Make sure the sleeve bearing washer was installed.
b. Verify the scale swivels cleanly in the cradle (Figure 8).
