7. Remove the ramps ¡ from the shipping carton and set the ramps in the holes
¢
provided at the front of the pallet . Ensure that the arrows on the ramps match the
pallet arrows as shown in Figure 2-2.
_________________________Caution ___________________________
In the next step, the leveler feet must be fully retracted to prevent contact with the
ramp or the floor when the cabinet is unloaded from the pallet.
____________________________________________________________

________________________WARNING __________________________
In the following step, use sufficient personnel to move the cabinet off the
pallet. The cabinet weighs 80.74 kg (178 lb) empty, and can weigh up to
420.94 kg (928 lb) fully configured.
If equipment is installe d in the cabi net, the c a binet may become top heav y
and could accelerate rapidly down the ramps if not restrained. Be prepared
to guide and control the motion of the cabinet.
____________________________________________________________
9. Refer to Figure 2-3 and roll the cabinet down the ramps using sufficient personnel for
safety.
10. Wheel the cabinet to the de si r ed locatio n.
11. Adjust the leveler feet downward so that the cabinet is level and the load is removed
from the casters.
_________________________Caution ___________________________
Ensure that the leveler feet extend enough to carry the load of the cabinet so that
the casters spin freely. If not, damage to the casters will result over an extended
period of time.
