1.2 Considerations Before Installation
1.2.1 Forklift Derating
1.2.1.1 Capacity Reduction Calculation
The CLS fits most typical forklifts, but there are considerations that must be taken into account prior to installation. Due to the
extra weight of the CLS, the net lifting capacity of the forklift is reduced by approximately 10%. Use the formula below to
calculate the amount to down-rate the lifting capacity and determine the net capacity of the forklift.
Figure 1-1. CLS Capacity Formula
1.2.1.2 CLS Classes and ID Plates
An updated ID plate on the forklift stating the new lifting capacity and center of gravity information is required per OSHA rules
and regulations.
Figure 1-2. Forklift CLS Reference
A = Truck Basic Capacity in pounds B = Inches from front wheel center line to fork face
C = Inches from face to truck rating point (usually 24) D = Weight of scale in pounds
E = Inches from front wheel center line to carriage face F = Inches from carriage face to scale horizontal center of gravity (HCG)
G = J + K (inches from carriage face to rear face of load H = Inches from fork face to new truck rating point
J = Thickness of fork K = Thickness of scale

1.2.2 Forklift Battery and CLS Installation
Take into consideration that the indicator power source is connected directly to the battery of the forklift. Most
typical is 12 volts for propane, gas and diesel forklifts.
12 volt systems must have a negative ground, ensure the forklift has a negative ground electrical system. The
CLS cannot operate on a positive ground forklift. Refer to the forklift manual to verify grounding requirements.
Standard CLS scales use 9-36 V power supply for use on 12 V batteries. Install the following for electric system forklifts:
PN 166162 – DC-DC Converter, CLS
PN 166161 – Power Line Filter, CLS (for static protection)
1.3 Power/Communication Box Introduction
The Power/Communication box transmits data between the scale and the hand-held device. The Mac ID label is used to pair
the CLS Bluetooth® interface with the hand-held device supplied by the customer.

1.4 Power/Communication Connection to Junction Box
The Power/Communication box receives data from the junction box through the Interface Cable.

1.5 iQube2TM CLS Junction Box
The latest CLS Series scales includes an updated version of the iQube2 junction box. This design is built to allow service
technicians to easily service the unit in the field. Below is an overview of the new features and functions.
It also replaces the older style junction boxes, originally used in the CLS Series scales.
Figure 1-5. iQube2 Junction Box
** Allows for connection to Revolution from the front of the forklift, using Type B USB micro connector. A built-in USB driver
allows easy interface capabilities. Simply connect to Revolution and select the new USB COM port generated. This can help
eliminate the coiled cable and communication/power box. If updating firmware, switch to a USB Micro A connector.

2.0 Scale Base Installation
This section describes procedures for installing the Cargo Lift Scale base.
Take all necessary safety precautions when installing the scale carriage, including wearing safety shoes and
protective eyewear, and using the proper tools, which are listed in Section 2.4.
The Cargo Lift scale is shipped from the factory with the scale already calibrated and all settings stored in the junction box.
Minimal adjustments and calibration might be necessary once the scale is installed onto the forklift. Those calibration steps are
contained in Section 5.3 on page 39.
2.1 Before Installation
Before installing the CLS on a forklift, the forklift should be in good operating condition for optimal weighing accuracy. Look for
the following items prior to installing the CLS 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 inch 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
scale’s performance
The power/communication box will be connected directly to the battery of the forklift. The CLS scale works with 9-36 VDC
power source.
All systems must have a negative ground.
2.2 Recommended Tools for Installation
Ensure the forklift meets the qualifications specified in Section 1.2 on page 2. Use the following tools to install onto the forklift:
Tool Size Purpose of Tool
Allen wrench 4 mm For service only, to remove junction box
Crescent wrench 2'' adjustable For adjusting the shim bolts and jam nuts
Tin snips or band cutters NA To cut the plastic banding surrounding the CLS while on the pallet
Torque wrench w/ 1/2" Allen 1/2'' To tighten the cleats to 125 ft-lb
Electric grinder For grinding the center pin if necessary and the mounting bolts
Wrench 7/16'' To connect power/communication box to mounting plates
Wrench & socket 9/16'' To connect mounting plates to forklift carriage
USB Type A to Type B Cable 6' Use with laptop for access to Revolution software for diagnostics, calibration and displayed weight
Level NA To perform angle zero calibration

2.4 Scale Base Installation
Use the following steps to install the scale base to the forklift.
Figure 2-4. Anti-shift Centering Pin, Shim Bolts and Top Cleat Locations (One Scale Configuration Shown)
Verify that the shim bolts are flush with the back plate of the scale. Not doing so places the entire scale out of
alignment when attaching it to the forklift and makes it difficult to make final adjustments once it is mounted.
1. Ensure the forks are removed from the forklift, move the forklift in close to the pallet and scale.
2. Ensure the anti-shift centering pin on the scale assembly is aligned with the center notch on the forklift carriage.
A. Centering pin should not touch the bottom of the notch on the original carriage, this will cause side to side tilting of
the scale.
B. Outside top cleats provide support to the scale assembly and the centering pin helps to position the scale on the
forklift carriage.
C. Centering pin should not bear any weight; if it does, the use of a grinder to grind down the centering pin will help
remedy that.
3. Tilt the mast forward slightly to catch the scale assembly.
4. Slowly raise the scale carriage slightly so the top cleats of the scale hook onto the forklift carriage; if the scale hook
and forklift carriage do not hook push the scale toward the forklift as it is being raised.
5. Tilt the mast back to secure the connection and raise the scale to shoulder height.
6. Attach the bottom cleats to the bottom of the scale assembly, so that the lip of the cleat is behind the scale carriage.
7. Torque the bottom cleat retaining bolts to 125 ft-lb.
Failure to properly torque the bottom plate retaining bolts may result in bodily harm or damage to equipment.
8. Adjust the shim bolts so there is a minimal clearance (0.020'') between the bottom cleats and the scale carriage; use
the provided feeler gauge.
Failure to adjust shim bolts to the clearance of 0.020'' may result in binding, poor accuracy or improper fit of
attachment to forklift.

2.5 Connect the Coiled Interface Cable to Junction Box
Figure 2-6. Connect Interface Cable
1. Loosen the bolt holding the cover to the scale assembly and remove cover.
2. Assemble loop clamp kit to the interface cable.
3. Route the interface cable through clips on backside of carriage toward middle. For proper interface cable routing,
tighten clips; the other end of the cable connects to the power/communication box (Section 3.0 on page 12).
4. Push the interface cable through the hole in the scale and connect it to the junction box.
5. Position the scale cover assembly and the loop clamp assembly on the scale and secure with the bolt and washer.
After successful installation (Section 2.0 on page 5 and Section 3.0 on page 12) and calibration (Section 5.0 on
page 38), replace the cover on the scale assembly and secure with bolt and washer.
2.6 Install Forks onto Scale Assembly
Figure 2-7. Fork Attachment
1. Align a fork to the center of the scale assembly making sure it is over the top of the assembly
2. Lift the carriage slightly to set the fork, and then slide the fork to the side of the scale; let it stop in the second notch
from the end and latch it in place; repeat process for other fork, sliding it the opposite direction on the scale
For accurate weighing it is recommended to leave forks at the second notch from the outside edge of the scale.

3.0 Power/Communication Box Hardware Setup
3.1 Mounting Locations
3.1.1 Mounting Location #1
The first preference for the mounting location of the box is 4-6'' from the top of the cage on the right rear pillar. If an access hole
is available in this location, route the power cable though the roll cage tubing to the battery.
Figure 3-1. Preferred Mounting Location
If there is no access hole available on the right rear pillar, check for an access hole on the left rear pillar. If there is no access
hole available on the rear left pillar, use the closest available access hole on the forklift roll cage.
If unable to mount power/communication box in this location due to items such as fire extinguishers, use Mounting Location 2
as seen in Figure 3-2.
3.1.2 Mounting Location #2
The alternate mounting location for the box is 4-6'' from the top of the cage on the left rear pillar. If an access hole is available in
this location, route the power cable though the roll cage tubing to the battery.
Figure 3-2. Secondary Mounting Position
If there is no access hole available on the left rear pillar, check for an access hole on the right rear pillar. If there is no access
hole available on the right rear pillar, use the closest available access hole on the forklift roll cage.

3.3 Power Cable Connection
Each installation is unique, depends on model and style of the forklift.
Do not connect the power cable to the power/communication box until battery connection and power hook-up is
complete.
The indicator power source is connected directly to the battery of the forklift. 12 volt systems are typical for
propane, gas and diesel forklifts.
12 volt systems must have a negative ground, ensure the forklift has a negative ground electrical system. The
CLS cannot operate on a positive ground forklift.
Refer to the forklift user’s manual for further verification of grounding requirements.
The power/communication box draws its power from the forklift battery. After it is mounted, run the power cable along the
shortest path that provides protection for the cable (away from moving or hot objects and pinch points), to the forklift battery.
Secure the cable at several points with cable ties.
Cable is required to run inside the roll cage tubing, if there are access holes for this purpose, using fish tape. If the cable is run
through a hole in a tube or panel, be sure the cable is protected against chaffing.
Figure 3-6. Route Power Cable (PN 153616)
When routing cables, do not cover any existing labels on the forklift in compliance with OSHA regulations.
Avoid running wires anywhere they could potentially be damaged.
* Do not let the cable touch or run along anything that gets very hot
* Keep the cable away from moving parts, including control linkages and fan blades
* Do not place the cable where it can be pinched by the compartment cover when closed
* Do not run the cable up against, or directly across the ignition wires
* Do not let the cable come in contact with engine fluids
* Secure the cable with cable ties at several points to prevent movement or loosening
* Inspect the cable often to ensure it has suffered no damage
CAUTION
Power cable must run inside
the overhead guard pillar.
