f. Before starting engine, operate hand primer pump control handle (11) until primer
pressure gage (2) gives a reading of 80 psi (551.6 kPa). and turn ignition switch (12) to
START position. Primer pressure gage (2) should maintain a reading of 30-60 psi
(206.8-413.7 kPa) while cranking engine.
g. Release ignition switch (12) after engine starts. Switch (12) will return automatically
to RUN position. Release clutch pedal (13) slowly.
h. Continue using hand primer pump control handle (11) until a constant reading of
30-60 psi (206.8-413.7 kPa) is shown on primer pressure gage (2). Engine should be
running smoothly in approximately 3 minutes. If vehicle engine does not start, go to
troubleshooting.
i. Push primer pump control handle (11) in and turn handle left or right to lock it in

j. Place preheater switch (4) in OFF position.
k. Adjust hand throttle control (1) until tachometer (7) indicates 800-1000 rpm.
l. Allow engine to run until temperature gage (8) indicates 120°F (49°C). Unlock hand
throttle control (1). Push it in until engine speed drops to normal idle (600-650 rpm).
m. Check your instruments! Refer to step q in paragraph 2-12.
n. Pull out emergency engine stop control (6) if the following conditions exist:
(1) Noisy engine and/or excessive engine vibration.
(2) Oil pressure does not register or suddenly drops to less than 15 psi (103.4 kPa).
(3) Sudden increase in coolant temperature beyond normal operating temperature of
175°F to 195°F (79°C to 91°C).
(4) Engine continues to run after ignition switch (12) and battery switch (5) are
turned to OFF positions.
