40. Improper acceleration or deceleration. - Faulty
starting and stopping action may be caused to a limi ted degree
for the same reasons as are cited in paragraph 39. Such improper
action may also be due to one of the replenishing check
valves being stuck in a partly open position.
41. Rotation cycle i.mc omp t e t:e . - An incompleted cycle
can be caused by the same conditions cited in paragraph 40 or
by incorrect adjustment of the control valve. Check the latter
against the prescribed adjustment of paragraph 26.
42. Failure to stop at station. - If the linkage is
properly adjusted the proj ectile ring will stop whenever operation
lever is moved to neutral regardless of the position of
valves. However if operation lever is held in position for
rotation the ring will not stop automatically, as intended,
when the ring station is reached because of any or all of the
following conditions:
(a) Control valve stuck in depres sed position.
Inspect and clean.
(b) By-pass valve stuck in depressed position.
Inspect and clean.
(C) Interlock valve stuck in starting position.
Inspect and clean.
43. St opp i ng aut of phase. - If the proj ectile ring
operates through 30 degree arcs of movementand stops but does
not stop at ring stations, the equipment has been coupled out
of phase. To correct this condition refer to the instructions
of paragraph 34-
