2500KGWA ASSEMBLY (CONTINUED)
Assembling a 2500KGWA Scale (continued):
It is recommended that the assembly be done by two people.
1. Place scale base on a flat, level, dry floor.
2. Locate and pick up the center handrail, then find the load cell cable, untie it and pull it out the bottom.
3. Position the handrail over the platform and feed the cable through the handrail support in the base,
being sure not to pinch the cable.
4. Slide the center handrail over the handrail supports on the base and fasten the handrail to the
handrail supports using four (4) M8 1.25 x ¾ screws (A), four (4) M8 washers (D) and the Allen wrench
(see Figure 1), then tighten the screws. DO NOT OVERTIGHTEN.
5. Pull forward on the handrail to tip the scale and gently place it face down on the floor, with care to
watch the ramp—it may flip open when the scale is tipped forward.
6. Grasp the load cell cable protruding from the bottom of the base and feed it through the protective
metal shield in the base of the scale, then plug it into the load cell port near the center of the base.
7. Pull the excess cable through the top of the scale.
8. Thread the 4 feet into the underside of the base. Each foot should be completely hand tightened and
then backed out 1-½ full turns. This allows for proper load cell operation for accuracy of the scale.
9. Carefully tilt the scale back to an upright position on the floor with care to watch the ramp—it may flip
down when the scale is tipped back. DO NOT DROP THE SCALE. Adjust the feet, to level the scale.
Be certain that the feet are NOT completely tightened into the base (see Step 8, above).
10. Rotate the display support 90˚ then position the Display Assembly close to the Display Support. Plug
the load cell cable connector into the load cell port on the rear of the Display then insert and secure
the cable into the center channel in the display. See Figure 2 for an illustration. Note: Do not attach
the power cord at this point. Wait until Step 14.
11. Slide the display assembly onto the metal display support insuring that the two metal tabs go into the
two slots in the rear of the display. Note: The load cell cable should now be secured in the
channel between the display assembly and the display support.
12. Insert four (4) Phillips pan head M4 screws (C) into the metal display support, and tighten (see
Figure 1).
13. Attach the Adapter Holder to the center rail using two (2) #8 x ½ (B) sheet metal screws, and tighten.
14. Connect the power adapter to the power port in the display, then insert and secure the cable into the
exposed portion of the second channel from the left in the back of the display (see Figure 2, above).
Hold the cord in place through the retaining slot on the rear cover and align the large rear cover tabs
with the slots on the rear of the display assembly. Apply light pressure to snap the cover into place
and secure it with two (2) Phillips pan head M4 screws (C). Do not plug the scale into a power
source until the scale is fully assembled.
15. Rotate the display to align it with the center handrail then attach the front and small rear display
support covers, applying light pressure to snap these covers into place.
16. Secure the power cord to the inside of the center handrail, using the 4 plastic cable clips, arranged
to hold the cord out of the way. The adhesive backing on the clips will peel off then the clips can be
fastened to the scale by applying light pressure.
17. The scale is now assembled. Plug the scale adapter into a power source and / or insert batteries.
