To use the optional Remote Control System, press the
“attach” button (
, fig. 1D) on the radio transmitter.
The vacuum pump will run until the vacuum pads seal
completely. If the lifter takes too long to attach, the
notification buzzer chirps and the LCD screen displays
“Vacuum not increasing normally”, along with a diagnostic
code (see “I
NTELLI
-G

” on page 36). In this
case, press the lifter firmly against the load to help the pads
begin to seal.

Reading the Vacuum Gauges
The 2 vacuum gauges of the dual vacuum system show the current vacuum level in positive
inches of Hg and negative kPa:
•
1A 1B
Green range (> 16" Hg [-54
kPa]): Vacuum level is sufficient
to lift the maximum load weight
(fig. 1A).
• Red range (< 16" Hg [-54 kPa]):
Vacuum level is not sufficient to
lift the maximum load weight
(fig. 1B).
2
If it takes more than 5 seconds for the
vacuum level to reach 5" Hg [-17 kPa]
on either vacuum gauge, 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” on page 30.
1..... Although a vacuum pad may become distorted during shipping or storage, this condition should correct itself with continued use.
2..... The gauge face colors do not correspond with the circuit colors.
3..... If the lifter is used above the maximum Operating Elevation (see “SPECIFICATIONS” on page 3), it may not be able to maintain sufficient vacuum
for lifting. Contact WPG for more information.
