3)

Make sure all vacuum pads will fit on the
load and will be loaded evenly (fig. 3A).
Consult the Per-Pad Load Capacity.
4) Place the vacuum pads in contact with the load surface until they begin to seal.

Reading the Vacuum Gauge
A vacuum gauge shows the current vacuum level in positive inches of Hg and negative kPa:
•
1B 1C
Green range (>16" Hg [-54 kPa]): Vacuum level is
sufficient to lift the maximum load weight (fig.
1B).
• Red range (<16" Hg [-54 kPa]): Vacuum level is not
sufficient to lift the maximum load weight (fig.
1C).
If it takes more than 5 seconds for the vacuum level to
reach 5" Hg [-17 kPa], press on any vacuum pad that has not yet sealed.
Once the pads have sealed, the lifter should be able to maintain sufficient vacuum for lifting,
except when used above the maximum Operating Elevation.

If it does not, perform the
“Vacuum Test” .
1..... Although a vacuum pad may become distorted during shipping or storage, this condition should correct itself with continued use.
2..... If the lifter is used above the maximum Operating Elevation (see “SPECIFICATIONS”), it may not be able to maintain sufficient vacuum for lifting.
