continuously for more than 10 seconds at a time.
If the Engine does not start, allow a 60-second
cool-down  period  between  starting  attempts.
Failure to follow these guidelines can burn out the
starter motor.

C A U T I O N

:  If  the  Engine  develops

sufficient speed to disengage the starter

but does not keep running (a "false start"), the
Engine rotation must be allowed to come to a
complete stop before attempting to restart the
Engine.

If the starter is engaged while the flywheel is
rotating, the starter pinion and flywheel ring gear
may  clash, resulting in damage to the starter.

If the starter does not turn the Engine over, shut
off starter immediately.  Do not make further
attempts to start the Engine until the condition is
corrected.

If the battery charge is not sufficient to turn over
the Engine, recharge the battery.

CAUTION

:  Do not attempt to jump start the

Engine  with  another  battery.    Starting  with
batteries larger than those recommended can
burn out the starter motor.

WARM-UP PERIOD

Run Engine at half speed for 5 minutes.

Do not run Engine at fast, or slow idle.

Operate Crawler at less-than-normal loads and
speeds for the first 15 minutes.

WARNING

:  Lethal Exhaust Gases

Engine exhaust gases contain poisonous carbon
monoxide.  Avoid inhaling fumes, and never run
the Engine in a closed building or confined area.

NOTE

:

Assembled Crawlers are "run in"

under no load at the factory for 15 minutes to
properly break-in their drive train.

TRAVELING
