other overhead objects.
• Do not leave LIFT TOOL machine unattended with an elevated load.
• Watch and keep hands, fingers, and clothing clear when equipment is in motion.
• Turn Winch with hand power only. If winch handle cannot be cranked easily with one hand, it is
probably over-loaded. Do not continue to turn winch past top or bottom of platform travel.
Excessive unwinding will detach handle and damage cable. Always hold handle when lowering,
unwinding. Always assure self that winch is holding load before releasing winch handle.
• A winch accident could cause serious injury. Not for moving humans. Make certain clicking sound
is heard as the equipment is being raised. Be sure winch is locked in position before releasing
handle. Read instruction page before operating this winch. Never allow winch to unwind freely.
Freewheeling will cause uneven cable wrapping around winch drum, damage cable, and may
cause serious injury. (C048, part 2 of 2)
CAUTION: If the System slide rails are installed above EIA location 29U, the [ServerLIFT
other qualified lift tool) must be used as a safety precaution for servicing. Position the lift tool
platform slightly below the bottom of the System drawer to account for the slight downward flex
when the drawer is extended out fully on its slides. Then gently raise the lift tool platform to stably
contact the bottom of the drawer, minding not to over force it as it could put upward stress to the
slide rails. A service-qualified ladder may have to be used to reach or properly work around the
System at such heights. While using a ladder, do not lean on or against the system drawer or lift
tool during service, and follow safe practices. (C051)
