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).

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.

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.

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).

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.).

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.
