TM 9-2350-261-10 THEORY OF OPERATION — Continued 0003 00 HAND THROTTLE CONTROL The hand throttle control is used to set the engine speed for various reasons. To set the engine speed, while pushing down the accelerator pedal, pull hand throttle control out until desired RPM is indicated by tachometer. Turn the hand throttle control clockwise to lock the control and counterclockwise to release the control. Once the hand throttle control is set, the engine will maintain the set speed without holding down the accelerator pedal. MAIN LIGHT SWITCH The main light switch is used to control all of the exterior lights and the instrument panel lights. To select lights, push up and hold the UNLOCK lever before moving desired lever to the position wanted. Refer to Operate Carrier Lights (WP 0039 00). AIR CLEANER INDICATOR The air cleaner indicator indicates if the air cleaner is operating properly or is plugged. When the air cleaner indicator is red, the air cleaner is plugged and needs cleaning. Press rubber dome to reset air cleaner indicator after air cleaner has been replaced or cleaned. FIXED FIRE EXTINGUISHER Refer to WP 0040 00 for operation of the fixed fire extinguisher. BATTERY GENERATOR GAUGE The battery generator gauge has the color red repeated. The first (left to right) red position indicates the batteries are dead (no power). The second red position indicates the batteries are being overcharged and could possibly blow up. During normal operation, the gauge should be in the green position. Refer to WP 0004 00 for other colors. TACHOMETER GAUGE The tachometer indicates engine speed and hours of operation. To read engine speed (RPM), multiply the large numbers on the gauge by 100, or add two zeros to number. 0003 00-2
