Reset all of the shutoffs or alarm components.
Check the engine lubrication oil level. Maintain the oil level between the “ADD” mark and the “FULL” mark on the oil level
gauge.
Check the coolant level. Observe the coolant level in the coolant recovery tank (if equipped). Maintain the coolant level to
the “FULL” mark on the coolant recovery tank.
If the engine is not equipped with a coolant recovery tank maintain the coolant level within 13 mm (.5 inch) of the bottom
of the fi ller pipe.
Observe the air cleaner service indicator (if equipped). Service the air cleaner when the yellow diaphragm enters the red
zone, or when the red piston locks in the visible position.
Ensure that any driven equipment has been disengaged. Remove any electrical loads.

in engine damage and/or personal injury.
When using starting fl uid, follow the manufacturer’s instructions carefully. Use starting fl uid sparingly and spray
it ONLY WHILE CRANKING THE ENGINE. Excessive ether can cause piston and ring damage. Use ether for cold
weather starting purposes only.

If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the
starting motor to cool before attempting to start the engine again.
NOTICE: Oil pressure should rise within 15 seconds after the engine starts. Do not increase engine speed until
the oil pressure gauge indicates normal. If oil pressure is not indicated in the gauge within 15 seconds. DO NOT
operate the engine. STOP the engine, investigate and correct the cause.
