Page 18: Preparing To Use The Remote Control System
OPERATION Preparing to Use the Remote Control System The optional radio transmitter (fig. 1A) and radio receiver enable you to activate the lifter's “attach” and “release” functions at distances up to 250' [76 m], provided you have a clear and direct view of the lifter and its status indicators. -
Page 19: 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”). 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 20: 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 21: Reading The Vacuum Gauges
OPERATION 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... -

Page 23: Controlling The Lifter And Load
OPERATION 2) Stop using the lifter until the cause of the vacuum loss can be identified: Conduct the “Pad Inspection” and perform the “Vacuum Test”. 3) Correct any faults before resuming normal operation of the lifter. Controlling the Lifter and Load When the lifter is ready, use the hoisting equipment to raise the lifter and load as needed. -
Page 24: 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 25: 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 26 OPERATION A load with overhang may force you to release the control handle as the load approaches the flat position. In this case, use hand cups (circled in fig. 1A) or other appropriate means to control the load. MRT4-DC3: #35068 Rev 7.2/4-21...
