3-9.1. CONTROL STATION - MAINTENANCE INSTRUCTIONS.
a. General.
(1) The control station provides remote control for the propulsion engine clutch and throttle.
(2) One handle (red knob) operates the clutch and reverse gear.
The other handle (black knob)
operates the throttle.
(3) The transmission of the operating force from the control station to the engine room is by means of
two mechanical push-pull cables, one for the reverse gear and one for the throttle.
b. Operation of the reverse gear.
The engagement of the clutch into the AHEAD position is accom- plished by moving the reverse gear
operating handle (red knob) 45 degrees in AHEAD direction. The opposite procedure is followed in REVERSE.
To put the reverse gear into NEUTRAL, the lever is brought to the vertical position. A spring-loaded plunger
detent is provided for readily locating the neutral position by feel, without having to rely on sight or guess work.
c.
Operation of throttle.
(1) The opening of the throttle is accomplished by moving the throttle (black knob) from the AFT
position (maneuvering speed) to the FORWARD position (full speed).
(2) The total stroke of the clutch or throttle operating cable is three (3) inches. The cable connection
on the control may be arranged so that the cable either pulls or pushes the engine lever.
(3) The control unit contains an electrical interlock switch to prevent energizing the starter when the
clutch is in the AHEAD or ASTERN positions.
