04/10 11 51191 Rev. 2

Section 2: Operations

2.1. INTRODUCTION

The installing technici a n is res pons ible that all personnel are fully
trained and familiar wit h the equipment's capabilities and
limitations before the installation is considered complete.

The Fairbanks Transport Scale Platform arrives at the user’s site partially
assembled.

The Instrument Pillar must be inserted into the Platform Base, and then fastened.

2.1.1. Unpacking

Follow these guidelines when unpacking all equipment.

• Check in all components and accessories according to the customer's order.

• Remove all components from their packing material, checking against the

invoice that they are accounted for and not damaged.

─ Advise the shipper immediately, if damage has occurred.
─ Order any parts necessary to replace those which have been damaged.
─ Keep the shipping container and packing material for future use.
─ Check the packing list.

• Collect all necessary installation manuals for the equipment and
accessories.

• Open the Indicator box(es), then follow exactly all the accompanying instructions
in the Installation Manual.

The Transport Scale is shipped in a wooden
crate on top of a pallet.

1. Remove the crate lid.

2. Locate the side closest to the wheels,

positioning it like a ramp in the
illustration.

3. Install the pillar to the base asse mbly.

4. Wheel the Scale off of the shipping

crate.

2.1.2. Assembling the Pillar

5. At the Wheel-base side of the

Platform, remove the four (4)
Fastening Bolts of the Cover using

the seven-sixteenths inch
(7/16”) Open-ended Wrench.

6. Pull out and unwrap the cables, set

the instructional CD aside, then open
the bag of assembly hardw ar e.

7. Using the pre-assembled Pull-string, carefully draw the Indicator Cable up

through the Pillar, and then out through the top Access Hole.

Allow extra slack on the cable.

8. Insert the Pillar into its collar on the Base.

9. Pull the cable firmly at the top to remove the slack.

10. Install the rubber boot over the load cell

cable and into the cable exit hole.

11. Use two Open-ended Wrenches.

A 9/16” on the 3/8” x 3-1/2” Bolts

through the Pillar and on the
Fastening Nuts.

12. Tighten the (2) ¼” x .50” Bolts using a

7/16” Open-ended Wriench to

secure the pillar to the base.

13. Wrap up excess Load Cell Cable and

secure in the compartment at the base
of the pillar.

14. Reinstall the Cover on the Platform with

the six (6) Fastening Bolts.

15. Wire the cable to the Indicator.

04/10 13 51191 Rev. 2

2.1.3. Positioning the Equipment

Position the equipment with the following points in mind.

• Rest the Platform on a smooth
surface, within 1/8”, and on a level
plane, within ¼” across both the
length and width of the platform .

• The four corners of the Platfor m must
rest solidly on the surface, and not
rock. Unlevel flooring and foreign
material under the Platform can cause
an “out-of-level” condition, and the
weight readings could be incorrect.

• Platform vibrations may also affect the
weighing accuracy. Wherever
possible, locate the platform as far
away from heavy, low frequency
vibrations as much as poss i ble.

Section 2: User Operations

• Do not load the platform if there is any
evidence of damage to the platform or
supporting structure.

• Ease of access is very important.
Allow plenty of room for maneuvering
a loaded dolly.

• Reading the Indicator is also important to workers, so place it in a very visible
position.

• The scale is to be placed on a flat, solid, level surface, one that fully supports the
weight of the platform plus a full capacity load.

• Whenever moving the scale to another location, it is important to lo cate the
Scale on a level area using the Bubble Level in the center of the Platform

for accurate and consistent weighing.

04/10 14 51191 Rev. 2

Section 2: User Operations

2.1.4. Moving the Scale

1. Remove all objects from the Platform.

2. Remove the AC Power from the Instrument, if applicable.

3. From the back of the scale, hold firmly onto the Handle Bars, place one foo t on
the platform base, then pull down on the Handle Bars until the unit rides only on
the wheels.

4. Transport the scale to its new location.

5. CAREFULLY lower the scale down to the floor.

6. Check the Bubble Level to confirm the scale is level.

7. Reapply AC Power to the Instrument, if applicable.

The Scale is again ready for weighing.

Section 3: Service and Maintenance

3.1. SCALE ASSEMBLY MAINTENANCE

Follow these point s to k eep the Tr ansport Scale well maintained.

• Clear all debris from between the spaces of the platform
sides, ramps, edges, and the surface beneath the platform.

• At the end of each day, wipe all surfaces with antibacterial
cleaner.

• Once a month, shine the Stainless Steel with only high
quality polish.

• Clean the wheels with a strong cleaner, then when
necessary, oil them only with

Motor Oil

.

White Grease or 30 Wt.

─ Spray lubricants are not recommended.

3.1.1. Scale Assembly Troubleshooting

Except for severe structural damages, most Platform Assembly problems can be
traced to the following causes:

• Material under or around the Platform.

• Improperly seated Load Cell Feet.

• Faulty Load Cells.

• Loose or damaged components.

3.1.2. Platform Assembly Testing

1. ZERO the Instrument Display .

2. Apply a test load of 25% of the Scale’s capacity to one corner.
─ The Instrument should display a weight reading within 0.1% o f the a ppl ied

weight, or One Instrument Division, whichever is greater.

3. Repeat Step 3 for all the corners, placi ng the s ame Test Lo ad on each corner.
