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.

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).

the air cleaner is plugged and needs cleaning. Press rubber dome to reset air cleaner indicator after air cleaner has been

replaced or cleaned.

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.
