10. For a diesel engine: If engine is at cold
ambient temperature, hold the Choke/Cold
Start switch (11) up for 10 seconds just

Gasoline engines have automatic chokes.
They do not use the Choke/Cold Start switch.
11. Turn the key (12) to START and hold it there
until the engine starts, or for 20 seconds,
whichever comes first. When the engine

NOTE
If you pause 30 seconds or more, after turning
the Master Key Switch to ON, an automatic
protection feature will prevent the ATB 42/50
from starting. If that happens, turn the key to
OFF, then try again.
A
CAUTION
If the engine does not start in 20 seconds, turn
the key (12) to OFF. Wait 60 seconds before
trying to start the engine again.
The engine should now be running, and the
ATB 42/50 is ready to begin work.
