CAUTION:
Your computer is heavy (it has an approximate minimum weight of 55 lbs) and can be difficult to
maneuver. Seek assistance before attempting to lift, move, or tilt it; this computer requires a two-man lift. Always
lift correctly to avoid injury; avoid bending over while lifting. See your
Product Information Guide for other
important safety information.
CAUTION:
The computer stand should be installed at all times to ensure maximum system stability. Failure to
install the stand could result in the computer tipping over, potentially resulting in bodily injury or damage to
the computer.

Carefully, with the help of an assistant, tip the computer back at a very slight angle from the ground.
3
Pull the front of the computer stand down towards the ground, to release it from the front of the
computer.
4
Pull the computer stand toward the front of the computer until the stand is free.
