). Always use as many pads as possible for each load being lifted, in order to
maximize lifting capacity and minimize load overhang.
To lift loads less than 60" [152 cm] long, remove the cotterless hitch pin from one folding arm.
Fold the arm upward and insert the pin in the lower hole, to secure the arm in the upright
position. Push the pin through the arm until the retaining ball emerges on the far side. Repeat
this procedure for the second arm.
WARNING: Closing pads shutoff reduces lifting capacity to
500 lbs [225 kg].
Deactivate the outer vacuum pads by closing the pads shutoff: Place the
valve lever perpendicular to the vacuum line.
To lift loads greater than 60" [152 cm] long, reverse these
procedures: Secure the pad arms in the horizontal position, and
place the valve lever
parallel with the vacuum line.

After the power switch is placed in the ON position, the vacuum lift light may subsequently turn on, because the lifter is
operating in stand-by mode at this stage. However, this does not indicate that the lifter is ready to lift a load.
