Shutdown Procedure

IF AN ENGINE MALFUNCTION CAUSES AN UNSCHEDULED SHUTDOWN, DETERMINE
THE CAUSE AND CORRECT IT BEFORE RESTARTING THE ENGINE.
1. Remove all load and allow engine to operate at low speed
for 3-5 minutes; this allows further reduction of internal
engine temperature.
2. Push Power/Emergency Stop switch in.
3. Turn Platform/Ground Select switch to Off.
Refer to Engine Manufacturer's manual for detailed
information.

Fuel Reserve / Shut-Off System (Diesel Engines Only)
The Fuel Shutoff System senses when the fuel level is getting low
and automatically shuts the engine down before the fuel tank is
emptied.
Depending upon machine setup, the machine will either keep
the engine shut down until the fuel tank is refilled or the operator
will be able to restart and run the engine for an additional min-
ute. After 1 minute, the engine will shut off for a second time and
the machine will return to the engine shutdown mode until the
fuel tank is refilled.
