WARNING: Make sure all vacuum hoses are coiled or routed so they cannot
become entangled, kinked or punctured during rotation or tilt.
MRT411LDC shown; see SPECIFICATIONS for other models’ Pad Spread.
Basic Configuration
This configuration provides a small, rectangular pad spread. Remove all 4 extension arms and
mount the vacuum pads directly to the arm sockets on the main pad frame. Note: Keep one set
of cotterless hitch pins with the extension arms at all times.
Linear Configuration
This configuration provides a narrow, rectangular pad spread. Remove 2 extension arms from
opposite sides of the lifter but leave the other 2 extension arms in place, as shown. Mount the
remaining vacuum pads at the arm sockets on the main pad frame. Then adjust the rotation
wear plate to utilize the secondary rotation stops (see discussion to follow).
Extended Configuration
This configuration provides a large, rectangular pad spread. Insert all 4 extension arms in the
main pad frame and secure them with the cotterless hitch pins provided. Mount the vacuum
pads at the outer ends of the arms, using the second set of cotterless hitch pins.
Secondary Rotation Stops
The lifter features a second set of rotation stops rotated 30° from the primary stops. The
secondary stops provide level load positioning when the pad frame is in the Linear Configuration
(see discussion preceding). To use these stops, loosen the two screws that secure the rotation
wear plate. Rotate the plate 30° counter-clockwise, to align the second set of stops with the
holes in the wear plate. Tighten the screws to secure the wear plate. Reverse this procedure to
realign the primary stops for use with the other pad frame configurations.
