Proper maintenance of the bombsight equip-
ment is necessary if that equipment is to funct-
ion properly, and if the desired objectives are
reached.
Maintenance may be defined as the proper
care of tools and equipment to insure maximum
efficiency and long life.
Three important items in maintenance are to
keep the units 1. dry; 2. clean; 3. lub-
ricated.
Bombsight equipment is very delicate, and it
must be protected from blows and rough handling.
Great care must be exercised so as not to drop the
equipment. Such an occurrence will ruin a sight
or stabilizer or in any case will require exten-
sive repairs at high cost and will necessitate
withdrawal of the unit from service until such
repairs can be made. The following precautions
regarding handling of bombsights and stabilizers
must be rigorously adhered to:
a. No man will carry more than one piece,
bombsight, or stabilizer, at any one time.
b. There is always some danger in trans-
ferring the equipment in and out of planes, where
footing is precarious. Here special care must
be taken and the man receiving the unit must have
a firm hold before the other lets go.
Special caution must be taken when the gyro
is turning up.
c. Any undo shock or jar may damage the
bearings thereby upsetting the delicate balance
of these instruments.
