Section 1: Introduction
1.1 INTRODUCTION & GENERAL DESCRIPTION
This manual provides information on installation, adjustment, and parts list for model
1000 Series portable platform scales. Please read carefully while assembling the scale.
The scale is factory calibrated and supplied ready to be assembled and placed into
service. For commercial applications, scale must be installed by a certified scale
technician.
NOTE: Adjustments to the weighing accuracy should only be made by trained scale
personnel. No modifications are to be made to this equipment.
Upon receipt, ensure that no shipping damage has occurred. Damage to the shipping
carton must be noted by the receiving party, and made known to the shipper. Claims for
shipping damage are made by the receiving party to the shipper.
It is the customer's/owner's responsibility to maintain the scale in good operating
condition and to protect the scale from accidental damage.

Section 2: Description
The 1000 Series Portable Beam Scale is constructed with a cast iron base and cast
iron lever system.
The indicating device is a mechanical beam (lbs. or kgs.) or with accessories, an
electronic instrument for displaying the weight.
NOTE
: The 1000/1001’s shipping weight is approximately 185 lbs.
Please use caution to prevent injury, and or damage to the product.

Section 3: Installation
3.1 UNPACKING
Check that all parts are included using the packing list.
Check for component damage that may have occurred during shipping.
3.2 ASSEMBLY
CAUTION: The scale base assembly, as shipped, weighs 185 lbs.,
use caution when lifting.
3.2.1 Wheel and Pillar Assembly
NOTE: The descriptions below refer to Item No to describe parts.
Use the parts list and ItemNo. in the list to identify those parts.
a. Set the scale base assembly (#4) upright on the floor.
b. Starting with an axle (#19), insert a cotter pin (#17) in one end, then place
one (1) washer (#18) & one (1) wheel (#16) over the open end.
c. Insert the axle's other end through BOTH holes in the base.
d. Place a wheel (#16), then 1 washer over the other end and insert a cotter
pin.
e. Repeat steps b-d for the 2nd axle.
f. 'Center' the axles in the base, then insert the locking screws (#15) into the
tapped holes in the bottom of the base (directly under the axle holes).
g. Tighten the locking screws, then secure the lock nuts (#14).
h. Screw the two (2) pillar rods (#1) into the base in the two (2) tapped holes
provided.
i. Place the pillar (#2) over the pillar rods with the cutouts facing to the left
and right of the platform
j. Insert the beam load rod (#35) down through the pillar, with the bent hook
on top, loose swivel hook on the bottom.

Section 3: Installation
03/13 7 51003 –Rev 3
3.2.2 Cap and Beam Assembly for Series 1000 Models
(Beam Installations):
a. Place the beam support (#39) over the pillar rods with the "hook" facing
to the right (when facing the scale platform).
b. Place the beam cap (#45) over the pillar rods, with the beam cap extending
to the right.
c. Place washers then 'acorn' nuts (#44) over the pillar rods, hand tighten only.
d. Locate the loop assembly that will support the beam assembly from
the beam cap. THIS LOOP MUST BE INSTALLED CORRECTLY TO
ALLOW THE POISE TO SLIDE TO ZERO. Orient the open end of the
loop assembly to face the end of the beam assembly when installing.
Refer to section “Parts 1000 –lbs”.
e. Fit the loop over the pivot on the butt END of the beam.
f. Insert the beam into the cutouts in the pillar, then the beam tip through the
beam lock (#43) so that the beam's MIDDLE loop (on top) will go OVER the
'hook' on the beam support (thus hanging from the hook).
g. Put the UPPER end of the beam load rod through the large END loop on the
butt of the beam.
h. From the rear of the scale, locate the BOTTOM end of the beam load rod
(the open part of the 'hook' on the bottom should face the scale base
(inward).
i. Holding the rod's BOTTOM hook, put it UNDER the pivot on the END of the
scale lever by lifting on the long lever end from the bottom.
j. Fit the beam lock (#43) over the beam tip and align with the 2 holes in the
beam cap and use the 2 screws to fasten the beam lock to the beam cap
with the handle facing the scale platform.
k. Hang the counterpoise (#54) from the beam tip loop.
l. Set the sliding poise to zero and hand tighten the screw.
m. Check that the beam is straight and does not touch the sides of the trig lock.
n. Shift the cap if necessary to straighten, then tighten the “acorn” nuts
securely
.

Section 3: Installation
03/13 8 51003 –Rev 3
NOTE
: Check that the weighing platform "floats" on the levers' pivots and bearings
and does not bind or set to one side. The platform should return to a centered
position if moved to any position then released.
o. Unlock the beam lock loop to allow the beam to balance.
p. The beam should move up and down freely coming to rest in the center of
the trig lock opening. Balance the beam by adjusting the balance ball at the
butt end of the beam, using a screwdriver.
Turning the screw CW will RAISE the beam
Turning the screw CCW will LOWER the beam.
q. If the beam will not balance using the balance ball:
Check that the poise is at "0" and the poise screw is snug.
Check that the platform is “free and floating.”
Check that the beam load rod is connected properly on BOTH ends.
Check that there is nothing under the platform inhibiting the levers (floor
debris).
Check that the counterpoise hanger, without any weights, is on the tip
loop.
Check that the beam is hanging from the middle loop.
Check that the beam lock is “open”
Apply a slight pressure to the scale platform and see if the beam tip rises.
If "YES" continue on to balance, if "NO" recheck mechanical assembly.
If the scale beam still does not balance, do the following:
Use a screwdriver to “center”the balance ball at the butt end of the
beam.
If the beam is "UP" apply small amounts of weight (BBs) to the top
of the counterpoise.
If the beam is "LOW" remove the counterpoise hanger, loosen the
hanger rod by turning and holding the bottom nut, and remove a
small amount of lead shot.
Add or remove small amounts of weight until beam balances.
Secure the counterpoise hanger with "added" or "removed" weight.

3.3 OPERATION
3.3.1 Zeroing
Before weighing an object, ensure that the scale is on ZERO with nothing on the
platform. To do this, set the sliding poise to "0" release the beam lock, and observe the
beam within the beam lock loop. (The beam should move from near the top to near the
bottom eventually settling 'balancing' in the center). If not, adjust the zero balance ball
using a flat blade screw driver.
If the beam stays at the top of the beam lock loop, turn the balance ball screw
counter-clock-wise.
If the beam stays at the bottom of the beam lock loop, turn the balance ball
screw clock-wise. Adjust the balance ball until the beam will balance at the center
of the beam lock loop.
3.3.2 Weighing
Check that the beam lock is “ON”(lever flipped to the
left).
Carefully place the object to be weighed in the platform center.
Run the sliding poise to the right end of the beam, and slowly release the beam
lock.
If the beam stays at the bottom of the beam lock loop, slowly slide the poise to
the left (decreasing) until the beam balances in the center. Read the weight on
the beam at the poise's pointer.
If the beam stays at the top of the beam lock loop, add counter poise weights to
the counterpoise until the beam “bottoms out”slowly slide the poise to the left
(decreasing) until the beam balances in the center. Read the weight on the beam
at the poise's pointer, and add the represented weight of all counterpoise weights
used.
