WARNING: Lift bar must be oriented vertically to lift

load.

Load Capacity and the Vacuum Gauge

The lifter's Load Capacity is rated at a vacuum level of 16" Hg [-54 kPa] (see SPECIFICATIONS).

Vacuum higher than this level registers in the green range on the vacuum gauge, to indicate that
the lifter is ready to lift the maximum load weight.

WARNING: Never attempt to lift load unless vacuum level registers higher than

16” Hg [-54 kPa].

Do not attempt to lift the load while vacuum registers lower than 16" Hg [-54 kPa]; such an

attempt could result in a load release and possible injury to the operator.

Monitoring the Vacuum Gauge

The vacuum gauge must remain completely visible to the operator, so that it can be monitored

throughout the entire lift.

WARNING: Vacuum gauge must be visible to operator throughout entire lift.

The lifter’s vacuum pump runs continuously to maintain sufficient vacuum for lifting the

maximum load weight. If the vacuum system experiences leakage while the lifter is attached to

the load, the vacuum gauge signals the reduction in vacuum to the operator. Make sure the
vacuum gauge shows a vacuum level of 16" Hg [-54 kPa] or higher while you are lifting a load.
If not, move away and stay clear of the load until it can be lowered to the ground or a stable

support.

WARNING: Stay clear of any suspended load while vacuum level is lower than

16" Hg [-54 kPa].

Discontinue lifter use until the cause of the vacuum loss can be determined. If the vacuum level

remains lower than 16" Hg [-54 kPa] when the lifter is attached to clean, smooth, nonporous
materials, the leakage is likely to be in the vacuum system. In this event, perform the V

: Inspection). If the vacuum loss cannot be remedied immediately, perform

inspection and maintenance as needed to identify and correct any deficiency before resuming

normal operation of the lifter.
