extending the tool about 3 inches (76 mm) by hand.
Throughout this travel, an increasing spring resistance
should be felt.
NOTICE
Although the text and figures that follow describe the
operation of the Loadbuster tool with SMD-20 Power
Fuses, the procedure is equally applicable to fuse
cutouts, disconnects, power fuses, and fuse limiters.
STEP 1. Reach across in front of the power fuse with the
Loadbuster tool and hook the anchor, located at
the top of Loadbuster tool over the attachment
hook on the far side of the power fuse. See
Figure 4.
STEP 2. Swing the Loadbuster tool toward the power
fuse and pass the Loadbuster tool pull-ring
hook through the pull-ring on the power fuse.
The pull-ring latch will de ect and, upon com-
plete entry of the pull-ring, will spring back,
locking the Loadbuster tool to the pull-ring. The
Loadbuster tool is now connected across the
upper contact of the power fuse. See Figure 4.
