• When the engine is warmed up or the ambient tem-
perature is above 10°C (50°F), it is not necessary to
operate the glow plugs before starting the engine.
• When the ambient temperature range is 10°C (50°F)
to -5°C (23°F), press and hold the preheat button for
five seconds before starting the engine.
• When the ambient temperature is below 2-5°C (23°F),
press and hold the preheat button for ten seconds
before starting the engine.

Start Switch

The start switch (refer to Figure 3) works like an automo-
bile ignition switch.
• Hold the switch in the start position until the engine
starts, then release it to on.
• If the engine dies, the switch must be turned to off
before it can be turned back to start.
An alarm sounds, when the switch is turned on, to warn
others that the machine engine is being started.
Note
On some machines it may be necessary to pause about
three seconds in the on position before going to start so
the starter can engage.
