OPERATION

IMPORTANT:

• Do NOT operate starter for longer than 15 seconds at a time.

• If engine does not start, wait at least two minutes before trying again.

• After the third 15 second crank attempt, allow solenoid to cool for 10 minutes before further

cranking attempts. If engine still does not start, refer to

6.1 Engine Troubleshooting, page 387

.

Cold Start

WARNING

If starter engages with steering wheel unlocked, ground speed lever out of NEUTRAL, or header clutch
engaged, DO NOT START ENGINE. See your Dealer.

IMPORTANT:

Do NOT operate engine above 1500 rpm until engine temperature gauge is above 100°F (40°C).

When the engine temperature is below 40°F (5°C), follow the procedure for a normal start. Refer to

Normal Start,

page 107

. The engine will cycle through a period where it appears to labor until the engine warms up. The throttle

is nonresponsive during this time as the engine is in “WARM UP” mode. This mode will last from 30 seconds
to 3 minutes depending on the temperature. After the engine has stabilized and is idling normally, the throttle
becomes active.

Engine Warm-Up

Allow engine to run with throttle lever (A) at or near
low idle position until temperature gauge (B) reaches
approximately 100°F (40°C).

NOTE:

Scroll through cab display module (CDM) for
engine temperature.

Figure 4.10: Operator Console

Engine Intermediate Speed Control (ISC)

The engine operating speed can be programmed to enable the windrower to operate at reduced engine rpm (that
is, 1800, 2000, or 2200 rpm) without significantly affecting the ground or header speeds. The default setting is 2200
rpm or the last selected rpm.

NOTE:

Previous M-Series windrower models included an OFF (full throttle) option which is NOT available
on the M155.
