To Start Engine
1. Depress the clutch-brake pedal and set the park-
ing brake.
2. Place the lift lever in the DISENGAGED position.
3. Set the throttle control in the FAST position.
4. Pull choke knob out to choke engine.
NOTE: A warm engine requires less choking than a
cold engine.
5. Turn the ignition key to the START position. When
the engine is running, let the key return to the ON
position.
NOTE: The best starter life is provided by using short
starting cycles of several seconds. Prolonged crank-
ing can damage the starter motor if cranked more than
15 seconds per minute.
6. Push choke knob in gradually. Move the throttle
control to desired engine speed.
To Stop Engine-Turn ignition key to OFF position.
CAUTION: Always remove key from switch when leav-
ing equipment unattended or when equipment is not
in use.
Cold Weather Starting Tips
1. Be sure to use the proper oil for the temperature
expected.
2. Declutch all possible external loads.
3. Set throttle control at part-throttle position.
4. A slightly richer fuel mixture, obtained by turning
carburetor needle valve 1/8 turn counterclockwise,
will usually improve cold starting.
5. A warm battery has much more starting capacity
than a cold battery.
6. Use fresh winter grade fuel. (Winter grade gasoline
has higher volatility to improve starting. Do not use
gasoline left over from summer.)
