CAUTION: Examine each air filter regularly, and empty when necessary.
Two air filters help protect the vacuum generating system from contaminants. However, the
lifter is not intended for use on wet load surfaces because the filters would not prevent liquid
from entering the vacuum system. The operator must examine each filter regularly and remove
any liquid or other contaminants found inside (see MAINTENANCE: A

). To
access the air filters, remove the cover indicated in OPERATING FEATURES.
Preparing to Use the Optional Remote Control System
If the lifter is equipped with a Remote Control System, the operator can engage the lifter's apply
and release functions at distances up to 250 ft [76 m], provided there is a direct and clear view
of the lifter and its status indicators from the operator location (see MAINTENANCE: R

). When lifting a load from a remote location, the operator must monitor
the lifter at all times to make sure that it is functioning as intended. 6 In addition, the operator
must exercise special care to ensure that the load is landed and supported correctly before
releasing the load (see

The radio transmitter is also equipped with an emergency transmitter disconnect that prevents
the transmitter from sending any transmission. This button should not need to be used, but
may have to be reset if accidentally engaged. To reset, twist the button clockwise while
allowing it to spring outward to its normal position.

Be sure to adjust the position of vacuum pads and/or cross members of the pad frame T-arm
assemblies, so as to optimize load support and minimize load overhang for the intended use.
Pads must be arranged symmetrically, to keep the lifter balanced. Note: Use only 2 pads on
each T-arm assembly.
1) Remove the cotterless hitch pin from one sliding / movable pad mount.
2) Reposition the pad mount at the desired position along the cross member of the pad frame T-
arm assembly, and align the holes for the cotterless hitch pin in the pad mount with the
corresponding holes in the cross member.
3) Secure the pad mount by pushing the cotterless hitch pin through the holes until the retaining
ball emerges on the far side of the pad mount.
4) Make sure that the vacuum hose serving the pad is not pinched, kinked, cut or abraded and
that it will not interfere with lifter operations.
5) Repeat steps #1-4 to position other pad mounts as needed. Always position pads so as to
create a symmetrical arrangement of the pad frame, and make sure that all vacuum lines are
functioning correctly.
Note: Depending on the position of pad mounts, the pad frame may extend beyond the edges
of smaller loads. When moving such loads, be careful to avoid any obstacles to the pad frame,
as well as to the load.

The Remote Control System is designed with safeguards to prevent multiple lifters from responding until a clear transmission
is received. Nevertheless, radio controlled lifters should be tested to ensure that each transmitter controls only one lifter. The
buttons located on the lifter function regardless of any radio transmissions in the vicinity.
