In order to be considered clearly audible,
the alarm volume must exceed ambient noise by
at least 15 dBA at the operator position.
6
Since the Maximum Alarm Volume is 103 dBA,
ambient noise must not exceed 88 dBA under any circumstances. Furthermore, if ambient noise
measures 88 dBA, the alarm volume must be set to maximum and the operator must remain
within 2 ft [60 cm] of the warning buzzer, in order for it to be effective.

Each shutoff on the pad frame controls the vacuum line to the adjacent vacuum pad. By
activating or deactivating the vacuum flow at specific pads, the operator can use the lifter to
handle loads of various weights and dimensions (see Load Capacity and Maximum Pad Spread in
SPECIFICATIONS). In addition, certain pads may be deactivated in order to avoid holes in the
load surface. To support the maximum load weight and larger load dimensions, all pads must be
activated; for smaller weights and dimensions, some pads may be deactivated,
provided that
the lifter still has sufficient capacity to support the load
(see INTENDED USE: L

HARACTERISTICS
).
WARNING: Closing any pad shutoff reduces lifting capacity.
To activate a pad, open the pad shutoff (place valve lever
parallel
with
vacuum line); to deactivate a pad, close the pad shutoff (place valve lever
perpendicular
to vacuum line). To calculate the lifting capacity when some
pads are deactivated, consult the Per-Pad Load Capacity rating (see
SPECIFICATIONS) and multiply by the number of pads currently
activated. Always activate pads in a symmetrical configuration, to keep
the lifter balanced while lifting, and use as many pads as possible for
each load being lifted, to maximize lifting capacity and to minimize load
overhang.

Consult CE Standard EN 457 for alternative ways to determine whether the alarm is clearly audible to operators.
