Wood’s Powr-Grip VLGG1011LDC - Manual (Page 15)

Rev 24.0/5-14 13 VLGG10-DC: #35164
In Case of Power Failure
The lifter is equipped with a vacuum reserve tank, designed to maintain vacuum temporarily in
case of a power failure (ie, in battery).
WARNING: Stay clear of any suspended load in the event of a power failure.
Although the lifter is designed to support the load for at least 5 minutes without power, this
depends on many factors, including the condition of the load and the lifter’s vacuum system (see

). If a power failure occurs, keep all personnel clear of the suspended load until it can safely
be placed on the ground or a stable support. Correct any deficiency before resuming normal
operation of the lifter.

WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, turn the apply/release switch to the “RELEASE”
position (counter-clockwise) to force air into the vacuum pads, quickly breaking the vacuum seal.
Continue to hold the apply/release switch in this position until the pads disengage completely
from the load.
When the apply/release switch is no longer held in the “RELEASE” position, it automatically
returns to the neutral position. Do not turn the apply/release switch to the “APPLY” position until
the pads are contacting the next load to be lifted. This conserves battery energy and reduces
the time required to apply the pads to the load, by preventing the vacuum reserve tank from
losing its vacuum.
