Important Safety Instructions
Read and understand all these safety
instructions before using the product.
Do not mount the Desk Base or Wall Mounted Bracket
of the Arm on an unstable surface or any surface that
could not mount the Desk Base rmly.
For safety reasons, the internal gas-strut of the LCD
Arm product was pre-adjusted in the factory to the
lowest force to prevent the Arm body from being re-
coiled during installation.
During installation, beware of the recoil of the Arm
body when attaching or detaching the LCD monitor to
the Arm. To prevent damage or injury when changing
the LCD monitor, always readjust the gas-strut to the
lowest force level to control the recoil of the Arm body
when the LCD monitor is detached.
Do not attempt to disassemble, service or modify the
product by yourself.
Use only a slightly damp cloth to clean the Arm sur-
face. Never apply ammable solvents like alcohol,
benzene, thinner, etc. to the product.
Do not use or mount any unsuitable/oversized/non-
standard monitors on the product.

LCD Monitor Attachment
The combination 75/100mm VESA plate is pre-mounted to the Workrite Poise.

M4 x 6mm (or M4 x 10mm) screws or screws provided by the manufacturer.

Arm Adjustment
Adjust the Monitor Tilt Action
Vertical Movement
Depending on the weight of the monitor, adjustments may be required to the Arm. This can be
done by using the M5 Hex wrench provided.
IMPORTANT
When performing this adjustment, the Arm must be in a HORIZONTAL position as shown
above. To prevent damage to the aluminium Arm body, remove the M5 Hex Wrench before
releasing the Arm from the horizontal adjustment position.
If the Arm tends to drift down or rise up when positioned, it will be necessary to make small
adjustments at the Adjustment Screw. The above shows the adjusting method. The M5 Hex
wrench provided should be used to make this adjustment.
If the Arm tends to rise, the M5 Hex Wrench should be turned clockwise to decrease the tension
until the Arm reaches a stable position.
If the Arm tends to fall, the M5 Hex Wrench should be turned counter-clockwise to increase the
tension until the Arm reaches a stable position.
Depending on the size of your LCD monitor, it may be required to adjust the Tilt Adjustment screw.
If the monitor doesn’t hold its tilt position or is too hard to tilt, adjust the screw directly behind the
LCD screen with the M5 Allen wrench provided (clockwise to tighten, counter-clockwise to loosen
as shown on the graphic near the adjustment screw). Check the monitor, and adjust again as necessary.
