C . Transporting the transformer drawer:
1 . Rotate the lifter winch clockwise (see Figure 23) until the
lifter pan clears the floor a couple of inches .
2 . Release the lifter brake by stepping down on the brake
release (see Figure 27) .
3 . Grasp the lifter handles and push the lifter with the trans-
former drawer to its installation area (see Figure 23) .
D . Installing the transformer drawer into the auxiliary compartment:

It is not necessary to use a lifter to insert a transformer drawer into a
lower auxiliary compartment . The drawer can be rolled directly on the floor
and into the compartment .
1 . Once the lifter with the transformer drawer has been trans-
ported to the auxiliary compartment, maneuver the lifter
inline with the front of the switchgear so that each side of
the lifter pan will clear the switchgear side sheets when the
pan is moved into place .
2 . Refer to Figure 28 . Push the lifter with pan up against the
front of the switchgear section . The pan guide-stops will
guide the pan into the compartment and align the pan rails
into the correct position with the compartment guide rails .
The guide-stops butt up against the switchgear side sheets
and prevent the lifter from moving too far into the compart-
ment . As the pan is moved into place, pan safety latches
bias off the switchgear side sheets and latch to the side
sheet flanges when the pan is fully in place . These safety
latches, along with the lifter brake, prevent the lifter and pan
from backing out of the compartment when the drawer is
moved in and out of the compartment .

3 . Lower the lifter pan by rotating the winch counterclockwise
until the pan rests on the compartment floor sheet . For an
upper compartment, only the front of the pan will rest on the
floor of the compartment . In any case, make sure the lifter
bar remains in the pan bracket (see Figure 24) and the pan is
level with the compartment floor .
4 . Lock the lifter in place by stepping down on the lifter brake
5 . Stand to one side of the lifter (opposite the front switch-
gear door hinges), push down on the drawer safety latch to
release the drawer from the lifter pan (see Figure 29), and
push the transformer drawer into the compartment (see
Figure 30) until the drawer comes to a stop and latches into
place . An audible “clicking” noise can be heard when the
drawer latches in place . Pull back on the drawer to confirm it
is fixed and latched in place .
