OURGP11,0000076 –19–27JUL06–3/3
RG13280 –UN–30OCT03
Start And Idle Engine On Earlier Panel (Left) or Later Panel
(Right)
A—Key Start Switch
B—High-Low Speed Select Rocker Switch
C—Bump Speed Enable Rocker Switch
D—Speed Select Rocker Switch
E—Analog Throttle Control (Optional)
5. Turn the key start switch (A) clockwise to crank the
engine. When the engine starts, release the key switch
so that it returns to the “ON” position.
IMPORTANT: If the key switch is released before the
engine starts, wait until the starter and
the engine stop turning before trying
again. This will prevent possible
damage to the starter and/or flywheel.
6. After engine starts, idle engine at not more than 1200
rpm until warm. (See WARMING ENGINE later in this
section).
Panels with high-low speed select rocker switch
(B) only: Set rpm using bump speed enable switch (C)
with speed select rocker switch (D).
Panels with optional analog throttle (E): Set either
high-low speed select switch (B) or analog throttle (E)
to slow speed, and set desired speed with remaining
control.
NOTE: Engine control unit (ECU) reads the higher of the
high-low speed select rocker switch or the analog
throttle speed settings.
7. Check all gauges for normal engine operation. If
operation is not normal, stop the engine and determine
the cause. (For normal gauge pressures and
temperatures, see BREAK-IN SERVICE earlier in this
section.)
NOTE: Hand throttle may have an analog potentiometer
(E) for changing engine speeds (See “Changing
Engine Speeds” later in this section).
