7. For all fuses except 25-kv Fault Fiter Electronic Power
Fuses, remove the fuse from its hinge as follows:
(a) Grasp the universal pole with both hands (approxi-
mately 2 feet apart), with one hand at the opposite
end of the pole from the Grappler.
(b) Position the Grappler cone in the fuse pull ring
and cradle the fuse in the Grappler prongs. See
Figure 22.
(c) Stand in a normal, upright position facing the uni-
versal pole. Move the pole forward until resistance
between the Grappler and the fuse is felt (approxi-
mately 2 inches). Then remove the fuse from its
hinge with a forward and upward lifting motion.
See Figure 23.

DANGER
Keep the fuse away from the Uni-Rupter contacts
when removing the fuse from its hinge. Touching the
contacts will close the circuit which can cause a
flashover and serious injury. Always place the
dual-purpose front barrier in the "slide-in" position
whenever a fuse is open or is being removed from or
installed into its hinge.

accordance with safe operating procedures and rules,
and then remove the fuse from its mounting by hand

pended position using the Grappler. See Figure 13. Also

Then close and latch the doors, and padlock securely.
