2.2 Before Installation
Before installing the CLS-420 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-420
onto a forklift:
• Inspect the forklift tines 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.
It should be noted that while Rice Lake’s CLS-420 will fit most typical forklifts, some considerations must be
noted. The height of the carriage, width of the carriage inside of the guards, if applicable and voltage of the fork
truck must be taken into consideration.
The indicator will be connected directly to the battery of the fork truck. Ensure the type and style of fork truck and
the type of power it provides will be compatible with the indicator. Most propane, gas, and diesel fueled fork trucks
provide 12 volts of power. Some diesel models also provide 24 volts and electric fork trucks provide 36 to 48 volts
of power. The CLS-series scales work with 12-36 VDC power source.
Important
All systems must have a negative ground.
2.3 Tools Needed to Install the CLS-420 Onto the Fork Truck or Mobile Lift
Once the forklift is deemed in good mechanical and operating condition, you’ll need the following tools to remove
it from its shipping pallet and install onto the forklift.
Table 2-1. Recommended Tools for Unpacking the CLS-420
Tool Size Purpose of Tool
Socket wrench 3/4" To unbolt the fastening bolts holding the scale to the pallet and to
open the top cover plate for wired versions
Allen wrench 1/2" To bolt and unbolt the bottom cleats of the scale
Wrench - 2" adjustable 1-1/2"*
1-5/8"* For adjusting the shim bolts and jam nuts
*Note: Use a 2" adjustable as both the shim bolts and jam nuts are
painted and a smaller wrench wouldn’t fit.
Tin snips or band cutters To cut the metal banding surrounding the CLS while on the pallet
Torque wrench w/ 1/2" Allen 1/2" To tighten the cleats to 125 ft-lbs
Electric Grinder - if necessary For grinding the center pin if necessary
