Unloading the MBM from the Pallet
The MBM pallet consists of four metal angle supports secured to plywood/polyfoam
laminated skids. The skids act as shock absorbers for the MBM during shipment.
WARNING:
Unit is extremely heavy. If unloading instructions are not closely
followed, the unit may tip and cause serious injury.
Turning the jacking bolts unevenly may cause the unit to become
unbalanced. To prevent tipping, raise and lower the jacking bolts
evenly and sequentially. The unit should only be raised approximately
3 mm ( 1/8 in.) above the floor (just enough to remove polyfoam skids).
1. Remove the doors. Remove the retaining screw located inside each door at
the bottom hinge pivot point, then lift off the door. Save the retaining screws
for reinstallation of the doors.
2. Locate the field kit packed inside the unit. Locate the four ½-in. jacking bolts
and install them in the threaded holes in the front and rear supports. Place a
floor protector underneath each jacking bolt, and screw the bolts down until
they contact the floor protectors. The floor protectors prevent the floor from
being damaged by the jacking bolts.
WARNING:
Module may fall. Do not loosen hardware attaching the side or front/rear
shipping supports to the module base. Also, do not loosen the shipping
supports from each other. The module must be lowered using jacking
bolts before the shipping supports can be removed.
3. Loosen, but do not remove the hardware holding the plywood/polyfoam skids
to the front and rear supports (labeled “1” in Figure 4 --- 8 places).
4. Turn each jacking bolt clockwise sequentially, no more than two full turns each,
until the foam cushions clear the floor by approximately 3 mm ( 1/8 in.).
5. After the plywood/polyfoam skids clear the floor, remove the hardware
loosened in step 3. Pull the skids out from under the MBM. Discard or recycle
them in a responsible manner.
