Vacuum Level on Optimal Surfaces

When the lifter is attached to clean, smooth, nonporous load surfaces, it should be able to

maintain a vacuum level in the green range on the vacuum gauge, except when used at high
elevations (see SPECIFICATIONS: Operating Elevation). If not, perform the V

ACUUM

T

EST

(see

MAINTENANCE) to determine whether there is a deficiency in the vacuum generating system.

Vacuum Level on Other Surfaces

When the lifter is attached to contaminated, rough or porous load surfaces, it may not be able to

maintain a vacuum level in the green range on the vacuum gauge, due to leakage in the seal
between the vacuum pads and the load surface. In the case of contamination, thoroughly clean
the contact surfaces of the load and the vacuum pads (see MAINTENANCE: V

: Cleaning), and reapply the lifter to the load. If the load has rough or porous

surfaces,

the operator must conduct a test to determine whether the lifter is designed

to lift the load

, as follows:

1) Make sure the lifter's vacuum generating system is functioning correctly (see MAINTENANCE:

).

2) Apply the vacuum pads to the load as previously directed.
3) When the vacuum level registers above 16" Hg [-54 kPa] on the vacuum gauge (see T

source.

4) Raise the load a minimal distance, to assure that it is supported by the lifter.
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.

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.
