DOWN, DETERMINE THE CAUSE AND CORRECT IT BEFORE RESTART-
ING THE ENGINE.

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.

Fuel Reserve / Shut-Off System (Gas or 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 minute. After 1 minute, the engine will shut off for a
second time and the machine will return to the engine shut-
down mode until the fuel tank is refilled.
