5) Monitor the vacuum gauge while the load is suspended for 5 minutes:

The lifter must

maintain a minimum vacuum level of 10" Hg [-34 kPa] during this time.

If not, the

load does not possess the characteristics required for using this lifter.

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

(see MAINTENANCE) and inspect the vacuum pads for damage (see MAINTENANCE: 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.

Certain load materials are too rough or porous to allow the lifter to form a seal which can be maintained for 5 minutes without

power. However, in geographical locations where CE Standards do not apply, it may be possible to use the lifter to lift such loads.
