WARNING: Never interrupt vacuum flow while operating hand cup; keep pump
running throughout lift.
The hand cup is designed for the vacuum pump to run continuously. Any interruption of the
vacuum flow during hand cup operation would result in the immediate release of the load and
possible injury to the operator (see ASSEMBLY and T

: In Case of Power
Failure to follow). Make certain that the contact surfaces of the load and vacuum pad are free of
any contaminates that could prevent the pad from sealing against the load (see MAINTENANCE:

).
Position the hand cup on the load so as to maximize stability while lifting the load. For sheet
materials, determine which will be the upper edge of the load when it is lifted, and position the
vacuum pad near that edge, centering the pad from left to right. Make sure that the vacuum pad
will fit entirely on the load’s contact surface (see SPECIFICATIONS: Vacuum Pad / Pad Spread).
Then gently press the hand cup onto the load until the pad seals against the contact surface.
Note: If the vacuum pad has been lying against a hard object, it may be slightly distorted.
Although initially it may be difficult to apply the pad to a load, this condition should correct itself
with continued use.
