the
words

LOCK/U³LOCK have been painted
over on some howitzers.
So remember, the UNLOCK posi-
tion is with the detent handle ´nob
turned as far outboard as it will goµ
The LOCK position is 90° from the
UNLOCK position with the handle
_uprigHt and pressed against its in¶
board stopµ
To make this easier to remember,
have your organizationa· maintenance
stencil ¸OCK and ¹NLOCK in the
right places with º»inc¼ stenci· ·etters.
½ere's another jewel to ´eep inside
your head: Both handles haVe to be in
stepµ If one ¼andle is in ¸OCK and t¼e
6
other in U³LOCK, you¾re going to
have problems if you raise the spade,
lower the spade or fire the howitzer.

Handles should be in ¹N¿
LOCK when you raise or lower the
spade.
When Àou have the spade cÁmpleteÂ
