SIGNAL WORDS:

This manual uses SIGNAL WORDS to indicate the likelihood of personal injuries, as well as the probable seriousness of those injuries, if the product is misused in the ways described. Other signal words call attention to uses of the product likely cause property damage. The signal words used appear below along with the meaning of each word:

Each person who assembles, installs, uses, or maintains this product should read the entire manual in advance and fully understand the directions. If after reading the manual you do not

understand an instruction, ask your supervisor or employer for clarification, because failure to adhere to the directions in this manual might result in serious personal injury.

Safe Use Recommendations:

We strive to identify all hazards associated with the use of our products. However, material handling is dangerous and no manual can address every risk. The end-user ultimately is responsible for exercising sound judgment at all times.

Material handling is dangerous. Improper or careless operation of this table might result in serious

personal injuries.

 Failure to read and understand the entire manual before assembling, using or servicing the product constitutes misuse. Read the manual whenever necessary to refresh your understanding of proper use and

maintenance procedures.  DO NOT install the table outdoors or in corrosive environments. ONLY install the table on compacted, improved surfaces (e.g. concrete) that are level and even. The surface must be capable of supporting the combined weight of the table and a full capacity load.  DO NOT use the table unless it is in normal operating condition. Inspect the unit as described in the inspection instructions on p. 6. DO NOT use the machine unless it passes every part of the appropriate inspection or until it is restored to normal operating condition.

 DO NOT use the table to lift people. DO NOT stand on the table frame or climb onto the tabletop.  Always watch the table carefully while applying a load to it.  Avoid pinch points. Pinch points are created as the table rises and lowers do to the pivoting motion of the scissor

legs. NEVER reach into or put any part of your body between the scissor legs.

 Always load the table properly (see p. 2). Center and evenly distribute all loads applied to this table.  The tabletop should elevate evenly as weight is removed from it and lower smoothly as weight is applied to it.

Watch for binding or jerky movement and listen for unusual noises. Remove the unit from service if you observe anything abnormal.  DO NOT apply loads to this table on broken or damaged pallets. Examine each pallet to confirm that no nails protrude from the surfaces and that all boards are intact. A damaged/broken pallet might interfere with tabletop rotation. A sudden stop while rotating the tabletop could cause the load to shift or fall.

 Lift a load high enough that it is clearly no longer in contact with the tabletop before backing away from the table.  If the table must be moved, completely unload it first.  DO NOT use this table UNLESS all labels are in place & readable (see “Labeling diagram” on p. 7.)  DO NOT modify this product in any way. Modifying the machine automatically voids the limited warranty (see p. 8).

and might make it unsafe to use.  If repairs are necessary, ONLY install manufacturer-approved replacement parts.

Proper use and maintenance are essential for this product to function properly.

 Always use this product in accordance with the instructions in this manual.  Periodically lubricate moving parts.  Keep the product clean & dry at all times. Always store the unit inside.  Only use approved replacement parts. To order replacement or spare parts for this equipment, contact the factory.

Installing/Removing Springs: Before loading the table, use the “Spring Combinations Table” on p. 2 to determine if more than just the orange spring is required. If the height and weight of a particular load requires adding springs, determine which springs are necessary as well as their proper placement as indicated in the “Spring combinations diagram” on p.

2. To install either the grey or purple spring:

1. Remove the appropriate tabletop plug;

2. Insert the spring through the opening. Make sure that the spring is seated properly;

3. Then, reinsert the plug and turn it as far as possible (the fins of the plug will contact stops) to secure the plug in place.

4. Look underneath the tabletop to confirm that the spring is properly seated as shown in the photograph to the right.

Table Loading Instructions:

Loading -- When using the spring table to load a pallet, always center the pallet on the table and center the load on the pallet. Distribute weight evenly on the pallet. For instance, if you are palletizing boxed items, add boxes in layers. Complete each layer before adding boxes to higher layers. Be careful while removing the loaded pallet from the table. Insert the forks of your lift truck through the pallet and slowly raise the forks. The table will rise at the same time. Continue to raise the forks until the tabletop is several inches below the bottom of the pallet before backing away from the table.

Unloading -- If you use the table to support a pallet while unloading it, apply the loaded pallet to the tabletop by slowly lowering the forks of your lift truck. Continue to slowly lower the forks as the springs compress under the load. Watch the pallet closely. When a gap appears between the top side of the forks and the pallet deck boards, stop lowering the forks. Raise the forks just enough to almost close the gap; then slowly back away from the pallet. Adjust the elevation of the forks if necessary to avoid over-compressing or under-compressing the springs. Unload the pallet evenly. Remove items in layers by completely unloading each layer before removing items from lower layers.

Inspections & Maintenance:

If any of the inspections described below reveal problems, tag the unit “Out of Service”. Restore the machine to normal operating condition BEFORE using it again.

A. Before each use, inspect the following components. Each component must be in normal operating condition. To establish normal operating condition, make a thorough record of the appearance, sound, and function of the various parts of the table when you first assemble it. Compare later observations to the record to determine whether the machine is in normal operating condition.

1. Frame: examine the frame, scissor legs, roller channels, and carousel. Look for damaged welds, warps, cracks, or other deformations.

2. Casters: examine each caster. Confirm that casters are not severely worn, swivel freely, and that the brakes firmly engage the wheels.

3. Springs: apply a test load to the table that is appropriate for each spring combination. The tabletop should move smoothly without binding or jerking. While applying the test loads, listen for unusual sounds.

4. Fasteners: check bolts and nuts. Make sure all fasteners are tightly connected.

5. Roller bearings: rotate the carousel. Watch and listen to the carousel as it rotates. If unusual noise is produced, or if the carousel binds, wobbles, or lurches, remove it and examine the roller bearings. Rotate each bearing to determine it requires lubrication. Replace all bearings that are significantly worn. Clean the underside of the carriage where the bearings make contact with it to remove debris that might interfere with them.

B. At least once per month:

1. Wiring: inspect the electrical system and look for loose connections and damage.

2. Clean the machine: remove dirt and other matter from all surfaces.

3. Labels: refer to the “Labeling Diagram” on p. 7. Make sure that all labels are in place and readable.

4. Batteries: remove corrosion from the posts if present.

Troubleshooting guide: The following table describes the most common issues that occur with these spring tables. If your unit experiences a problem not included in this guide, contact the factory for assistance.

Issue: Explanation Remedy

1) When a load is applied to the table, the carousel rotates on its own.

2) The carousel produces a lot of noise while it rotates

3) The tabletop lowers too much when a load is applied.

4) The tabletop does not lower enough when a load is applied.

5) The tabletop bounces or feels spongy when pressed.

a) Table is not level. a) Determine the state of levelness and

adjust the position of the frame to level

the unit. b) 1 or more carousel bearings need to be lubricated or replaced.

c) The load applied exceeds the weight limit of the spring combination.

d) The load exceeds the maximum capacity of the table (4,400 lb.) e) The spring combination is too strong for the load applied.

f) The shock absorber is malfunctioning. f) Examine the shock absorber. Replace

b) Rotate each of the bearings to

determine which are noisy and/or do not

rotate smoothly. Lubricate bearings. If a

bearing appears to be significantly worn,

replace it.

c) Remove the load and select the proper

spring combination for the load. (See

“Spring Combinations Table”.)

d) Reduce the load until it is within the

capacity of the table.

e) Remove the load and select the proper

spring combination for the load. (See

“Spring Combinations Table”.)
