2-33. Ramp
a. Lowering Ramp.
(1) If engines are not operating, start at least one engine to build up the hydraulic oil pressure.
(2) Move pilot air valve (5, fig. 2-8) control lever full aft to RAISE position.
NOTE
If one or both engines are operating on one side only, use the control lever on the engine operating side. Either
control lever may be used if at least one port and one starboard engine is operating.
WARNING
If the ramp is not held fully closed by the ramp cables, the force of the 7,000-lb ramp will cause the ramp latch
to swing sharply forward. This can cause injury or DEATH to the ramp latch operator by either striking or
throwing him overboard. Do not place thumb over the ramp latch. See figure 2-16 for proper method of
grasping ramp latch.
(3) Unlock ramp latch lever (1, fig. 2-8) on port and starboard side of ramp and lift ramp latch hooks from the ramp.
(4) Move pilot air valve (5) control lever full forward to LOWER position until ramp is down. After ramp is down, move control
lever to NEUTRAL position.
NOTE
The ramp may be stopped in any position by moving the control lever to NEUTRAL.
Figure 2-16. Proper method of holding the ramp latch.
b. Raising Ramp.
(1) Check that ramp latches are in the clear and that towing shackles, if mounted in tow bars, are not turned inboard since it is
possible for either or both swing inboard sufficiently to prevent complete raising or lowering of the ramp.
CAUTION
Remove dirt and foreign material from ramp seal area before raising ramp.
(2) Raise the ramp into full closed position by moving the pilot air valve control lever (5, fig. 2-8) full aft to RAISE position.
