1. Remove all corrosion.
2. Wipe off the surface with clean rags and wet with
petroleum spirits GE–D5B8.
3. Follow with a clean rag wet with methanol, then
wipe dry. DO NOT touch the cleaned surface
with bare hands.
4. Slush immediately after cleaning with
GE–D6C6A1 slushing compound.
SKIDDING
Use yellow pine timbers large enough to support the
weight of the machine. The recommended size is illus-
trated in Fig. 44.
PROTECTION
When any apparatus is shipped in the open, it should
be fully protected from rain, snow, dirt, etc., by covering
with some suitable weatherproof material.
ARMATURES
To prepare drilling motor armatures for shipment or
storage, clean, slush and wrap the armature. Then, se-

curely support and enclose the armature in a totally en-
closed wooden box of sufficient strength to protect the it
from damage.
1. Clean the armature by removing dirt, oil or
grease from its surface.
2. Treat all unpainted, exposed finished surfaces
as follows:
a. Remove any corrosion.
b. Wipe off the surface with a clean cloth dipped
in petroleum spirits, GE–D5B8.
c. Wipe off the surface with a clean rag, dipped
in methanol, and wipe dry. DO NOT touch the
cleaned surfaces with bare hands.
d. Immediately after cleaning, slush the cleaned
surface with GE–D6C6A1 shushing com-
pound.
3. Wrap heavy paper or cardboard around the com-
mutator for protection.
4. Wrap and secure waterproof paper around ar-
mature punchings. This will prevent saddle tim-
ber moisture from condensing on the core
punchings.
5. Wrap both ends of the shaft with Grade C, Type
1, wax treated cloth and tape it securely into
place.
NOTE: Wherever metal parts come in contact
with the wood, insert a good grade of water-
proof paper between metal and wood. This will
prevent rust formation from the condensation
of moisture on the metal.
PREPARATION OF BOX
1. Make a suitable box from yellow–pine lumber us-
ing timbers of proper size to support the weight of
each armature. See Fig. 45.
2. Make 4 saddle blocks of 3 by 6 in. timber cut out
to fit circumference of armature core. Nail two to
the bottom of the box in the proper position to
