WARNING: Maximum equipment loading of table assembly in addition to specied top is as follows:

 Maximum Top Weight: 128 lb (58.2 kg)

 Maximum Equipment Load: 300 lb (136.3 kg)

Loading should be evenly distributed over table surfaces.

V = 120 VAC, 60 Hz / 4 A maximum

FLAMMABILITY: All worksurfaces used must meet UL 962 ammability requirements

 Flame Spread Rating maximum 200

 Smoke Developed Index maximum 450

WORKSURFACE MATERIAL: This frameset is designed to accommodate worksurfaces made from Industrial Particle Board with nominal thickness

of 1.125". If the worksurface is not appropriate or not mounted correctly to the table, it could cause the complete table to be unstable, it may collapse,

and for an adjustable table, the electrical components may fail.

Intended for indoor use only.

For commercial use only.

IMPORTANT SAFETY INSTRUCTIONS:

When using an electrical furnishing, basic precautions should always be followed, including the following:

Read all instructions before using this Sierra HX Work Center.

DANGER: To reduce the risk of electric shock, always unplug this Sierra HX Work Center from the electrical outlet before cleaning or servicing.

WARNING: To reduce the risk of burns, re, electric shock, or injury to persons:

1. Unplug from outlet before putting on or taking off parts.

2. Close supervision is necessary when this furnishing is used by, or near children, invalids, or disabled persons.

9. Do not exceed maximum load recommendations.

Polarized Plug Instructions (Only applicable to products having a polarized plug power cord):

Some products include a polarized plug—see Figure A (One A/C plug blade wider than the other)—to reduce the risk of

electrical shock. A polarized plug only ts a polarized power outlet one way. If the polarized plug does not t properly into the

electrical outlet turn the power plug over to see if it then ts properly and fully into the outlet. If the plug does still does not t

the outlet, contact a certied electrician to install the correct matching polarized electrical outlet.

Caution: Never modify the power cord plug in any way

Double-Insulated Products Instructions:

Some products are double-insulated. No means of grounding is required or provided on a double-insulated product; nor is a

means for grounding to be added to the product. The plug in a double insulated system is shown in Figure A. Double-insulated

products are indicated with markings of “double-insulated” or the “double box symbol” or both.

Grounding Instructions (For grounded electric products only):

Products with grounded power cords are for use on a nominal 120 V circuit and has a grounded plug as shown in Figure B

Make sure the product is connected to an electrical outlet having the same conguration as the plug shown in Figure C.

Caution: Never modify, remove, or use adaptors that eliminate the ground connections from the grounded power cord

A/C Power:

Products sold in North America and other regions are 120 V A/C as marked on the power supply/control box of the furnishing

and are to be used on a normal 120 V A/C circuit. Always follow the instructions above for power connection using grounded or

double insulated power cords as supplied.

• Only use power cord(s) supplied with your electric product

• Never modify, alter, use an adaptor, or change the electrical system of this product in any way.

Warning: Doing so may cause risk of electrical shock or re

Illustration Disclaimer—Power Plug and Receptacle Images:

In some cases, the images in this instruction may not match the power cord supplied with your electrical furnishing based on your region.

Plug type, blade size, and shape may change.

For Center Foot, use "Glide Adjuster" as needed (comes in ¼" to ½" spacers).

✓ Cleaning instructions

To clean the Sierra legs, apply cleaner to a so cloth.

Suggested cleaners: Windex or Formula 409.

Do not use solvents and do not saturate or spray cleaners directly to work center base.

You must complete this

initialization step or your

work center will NOT

function properly.

Hold down the down

arrow until work center

moves slightly upwards!

✓ Replacement Parts

Visit http://workriteergo.com/documentation/other/workrite_ergonomics_pricing_specification_guide.pdf for

replacement parts.

Initialize Legs

Aer all legs and the switch are connected, and the power cord has been plugged in, hold the down arrow on

the switch until the legs make a short motion down and then back up. This initializes and synchronizes the work
