(1) Grasp the wire between the jaws, and apply the
locking sleeve with the thumb.
(2) Pull the knob to twirl the pliers which make
uniform twists in the wire.
(3) If further twisting is required, push the knob
back into the pliers and pull the knob again.
(4) When the wire is twisted as required, squeeze
the handles together to unlock the jaws and release the
wire.
(5) Cut the wire to the desired length with the side
cutter.
b. Care. Lubricate the spiral twister occasionally, and
apply a coat of light oil to all surfaces to prevent rust.
7-12. Deicer Boot Pliers. When a deicer boot is
installed, it usually is pulled on over rivnut studs to hold
it in place while the rivnut screws are started. To
provide a larger gripping surface to prevent tearing the
deicer boot, deicer boot pliers are used. These pliers
have
two
rods,
about
one
inch
long,
welded
perpendicularly to the jaws and wrapped with tape.
Figure 7-17 shows deicer boot pliers being used.

7-13. Leather Punch. The leather punch is used to cut
holes in the deicer boot for rivnut screws, as shown in
figure 7-18.
a. Description. The leather punch is shaped like a
pair of pliers, but has a selection of sharp-edged tubes
(for different sized holes) mounted on one jaw, and a
plate on the other.
CAUTION
Under no circumstances should an
attempt be made to cut holes in metal
with leather punch.
b. Use. To properly locate deicer boot holes, hold
deicer boot and fairing strip together. Punch holes
directly thru holes in fairing strip.
7-14. Deicer Boot Roller. The deicer boot roller is
used to roll the flaps of the deicer boot when cementing
them to the wing, as shown in figure 7-19. Occasionally
lubricate the roller axle to allow smooth rolling.
7-15. Crowfoot Wrenches. The crowfoot wrench is an
open-end wrench head which is turned with a socket
handle. It is used to remove and install bolts or nuts
where an obstruction would prevent the use of a regular
socket. A typical crowfoot wrench is shown in figure 7-
20.
