Page 18: T O Attach The Pads To A Load
OPERATION TTACH THE ADS TO A Make sure the contact surfaces of the load and vacuum pads are clean (see “Pad Cleaning” on page 32). Positioning the Lifter on the Load Center the pad frame on the load (fig. 1A). Make sure all vacuum pads will fit on the load and will be loaded evenly (fig. -
Page 19: Powering Up The Lifter
OPERATION Powering up the Lifter Press the lifter's power button ( — fig. 1A). The vacuum pump will run for a few seconds, ® as a normal function of the Intelli-Grip self- diagnostics. The lifter automatically tests the 9-volt battery for the notification buzzer each time the lifter is powered up. -

Page 23: T O Rotate The Load
OPERATION OTATE THE Make sure load is positioned correctly on lifter (as previously directed). Never disengage rotation and tilt latches at the same time, because this could result in load damage or personal injury. Make sure the load has enough clearance to rotate without contacting anyone or anything. -
Page 24: T O Tilt The Load
OPERATION ILT THE Make sure load is positioned correctly on lifter (as previously directed). Never disengage rotation and tilt latches at the same time, because this could result in load damage or personal injury. Make sure the load has enough clearance to tilt without contacting anyone or anything. - Page 25 OPERATION A load with overhang may force you to release the control handle as the load approaches the flat position.
