f.
Starting. Instructions (1) for starting, running, and stopping the engine are located on control panel
assembly (2). Instructions for automatic mode and manual speed control mode are provided. Manual speed control
mode is used when the retrofit kit has been installed. Refer to paragraph 2-15 for operating instructions with retrofit kit
installed.
(1)
Set PANEL LIGHTS switch (3) to the BRIGHT or DIM position to turn on panel lights.
(2)
Turn SET POINT switch (4) to middle of the START RANGE.
(3)
Set MODE SELECT switch (5) to MANUAL position.
(4)
Set START/STOP switch (6) to START position.
(5)
Press OIL BYPASS switch (7) located above START/STOP switch (6) and hold in while engaging
starter (8). This switch bypasses the low oil pressure circuit. When oil pressure is below 40 psi (276
kPa), the low oil pressure circuit stops the engine. Oil pressure is normally low when starting the
engine. This switch bypasses the circuit until the oil pressure reaches approximately 40 psi (276 kPa).
If engine fails to start within 10 seconds, release STARTER switch; do not attempt starting again
until starter motor stops turning. Failure to comply with this rule may result in serious damage
to the starter motor.
(6)
Hold STARTER switch (8) in UP position until engine starts. If the engine fails to start after four
periods of cranking, see troubleshooting procedures in Chapter 3.
(7)
Continue pressing OIL BYPASS switch (7) and observe oil pressure gage (9). After oil pressure builds
up over 40 psi (276 kPa), release the OIL BYPASS switch (7).
