Glow Plug Chart
Ambient Temperature Hold Glow Plugs On
Above 50°F (10°C) NO NEED
50°F (10°C) to 23°F (-5°C) Approximately 5 seconds
Below 23°F (-5°C) Approximately 10 seconds
Limit of continuous use 20 seconds
The glow plug light, located near the glow
plug switch, will illuminate when the switch is
depressed. The glow plug light indicates the glow
plugs are preheating the combustion chamber.
Important: Do Not crank the engine
continuously for more then ten seconds at a
time. If the engine does not start, allow a 30
second cool-down period between starting
attempts. Failure to follow these guidelines
can burn out the starter motor and/or fuel
solenoid.
7. Move the throttle to the “SLOW” (if in
“MIDWAY”) and let the engine warm up a few
minutes before moving the throttle to the “FAST”
position.
