2CLS-M Installation Manual
Introduction
The CLS-M Cargo Lift Scale is designed to fit on most forklifts. However when a forklift has been in use for a
while some of the basic components may become worn or damaged through everyday use and may inhibit the
installation process.
In some cases, if the wear or damage is excessive, the forklift may not be able to accept the scale and your local
Con-way manager should be contacted for review of corrections required for scale installation.
This document will assist you with installation to worn and damaged forklifts and how to determine if the forklift
will require repairs or updates prior to installation.
Take all necessary safety precautions when installing the scale carriage, including wearing safety
shoes and protective eyewear, and keep clear of pinching or crushing points.
Two people are recommended to perform the scale installation.
Before Installation
Before installing the CLS-M on a forklift, the forklift should be in good operating condition in order to get the
optimal amount of weighing accuracy. The following items are things to look for prior to installing the CLS-M
onto a forklift:
• Inspect the forks for any damage.
• Check the locking pin on the forks for proper function.
• Check and adjust the lift chain so the heel of the forks have 1/2” to 1” of clearance from the floor when
the carriage is down and the mast is vertical.
• The slot for the center pin should be clear of grease and debris.
• The top cleats of the forklift rest on the top of the scale and should remain clear of grease and debris that
could alter the scales’ performance.
Installation Preparation
To install the CLS-M Cargo Lift Scale to your existing forklift, follow the guidelines below to prepare the
forklift:
Remove existing weld-on components.
Figure 1. Remove Existing Welded Bar
Remove any components that have been welded to the mast to reduce side shift of previously installed scale to
allow for proper fit of top cleats using CLS-M forklift scale.
Warning
Bar welded to
scale mast to
prevent shift.

Side Shift Components
It is important to provide coverage against side shifting of the scale when it is attached to the forklift mast.
Coverage should extend past the scale enough to stop any shifting.
Check the existing components, if any, to make sure the provide adequate coverage.
Worn washer does not
prevent side shift.
Figure 2. Worn forklift side shift bolt and washer
Welded Washer
provides protection
from side shifting.
More coverage of
the scale would be
preferable.
Note
The side shift bolt and washer that are attached to forklift mast (Figure 2), appears to be worn and does
not have a large enough washer to provide protection from shifting of unit.
• Replace existing components with new components that will provide the appropriate cover to keep it
from side shifting.
• If none currently exist, install appropriate components.
Figure 3. Welded Washer to Prevent Side Shifting
Note
A washer has been welded to the mast of the forklift (Figure 3) to provide protection from side shifting of
unit. More coverage of the scale would be preferred.

Centering Pin
The centering pin is used to align correct placement in the center of the forklift scale. Centering Pin should not
touch the forklift carriage. It is used only as a safety mechanism to reduce side to side shifting of forklift scale.
Grind the centering
pin and/or forklift
carriage slightly for
more clearance.
Figure 4. CSL-M Cargo Lift Scale Centering Pin
• If the forklift carriage does not have enough clearance, slightly grind the scales centering pin and/or
clean up the forklift carriage center slot using a grinder to allow proper installation.
Note
Not all forklift carriages have the same gaps for the centering pin, based on year/model, service work
performed or years of wear from usage.

Top Cleats
Designed to securely hold the CLS-M Cargo Lift Scale on the mast of a Class II forklift with a 16” carriage.
Figure 5. Top View of Rice Lake Weighing Scale Installed
• Check that the installation location of the cleats on the forklift carriage mast is smooth and clear of any
excess material or debris.
Fits securely onto
the forklift mast.
Figure 6. Top Cleat Installation
• It is important that the top cleat fits securely onto the mast of the forklift carriage.
Note
While the top cleat appears to fit correctly in Figure 6, the side shift protection is not in place.

Bottom Cleats
The bottom cleat gap should not be more then 1/8” as shown in Figure 7.
Worn mast causes to much of a gap for
correct installation.
1/8” MAX
Incorrect Installation Correct Installation
Insert a feeler gauge to measure a.020 inch
thickness between bottom cleat and forklift
Figure 7. Bottom Cleat Installation
Note
The forklift carriage in Figure 7 appears to be worn over years of use and may need repair for proper
installation.
Check for proper seeding of top scale cleats onto forklift carriage as indicated in Figure 6. Interference of
material around the scale cleats may cause this gap to be larger.
Bottom cleat gap, should be 0.020”, using thefeeler gauge included with every unit (Figure 7). Adjust the shim
bolts on the scale carriage.
• If forklift carriage is not flat, may cause increased gap and improper installation.
• If bottom cleat and forklift carriage rub, it may cause mechanical interference and inaccurate weighing.
