5. The Backup and Support Frame are pre-assembled at the manufacturing facility and
therefore should arrive as a complete assembly. Attach the Cartridge to the Backup and
Support Frame Assembly using the 1/2" nuts and washers attached to the Cartridge.
Tighten the nuts until the lock washers are fully compressed (refer to detail drawings).
6. Secure the Jacks on the Cartridge and Backup into the “DOWN” position and “elevate” the
Cartridge to 305 mm ± 5 mm [12” ± 1/4"] at front, 330 mm ± 5 mm [13” ± 1/4"] at rear from
the ground. The Cartridge jack may have been shipped separately from the Cartridge. See
the decal on the rear of the Cartridge for assembly instructions. Torque bolts to no more
than 35 N-m [25 ft–lb].
7. Attach the “Support Frame Attachment Bracket” (2 ea. PN 605399) to the upper holes of the
Support Frame, (PN 615554) using the 1” diameter pins. Lower holes are for height
adjustment if necessary (see Figure 4).
