Glow Plug Chart

Ambient Temperature	Hold Glow Plugs On
Above 50°F (10°C)	NO NEED
50°F (10°C) to 23°F (-5°C)	Approximately 5 seconds

The glow plug light, located near the glow plug switch, will illuminate when the switch is depressed. The glow plug light indicates the glow plugs are preheating the combustion chamber.

Important: Do Not crank the engine continuously for more then ten seconds at a time. If the engine does not start, allow a 30 second cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motor and/or fuel solenoid.

8.Move the throttle to the “SLOW” (if in “MIDWAY”) and let the engine warm up a few minutes before moving the throttle to the “FAST” position.

Engaging the PTO

DANGER

The rotating blades under the mower deck are dangerous. Blade contact can cause serious injury or kill you.

Do Not put hands or feet under the mower or mower deck when the blades are engaged.

DANGER

An uncovered discharge opening will allow objects to be thrown in an operator’s or bystander’s direction. Also, contact with the blade could occur. Thrown objects or blade contact can cause serious injury or death.

Never operate the mower with the discharge deflector raised, removed, or altered unless there is a grass collection system or mulch kit in place and working properly.

The PTO push-pull switch engages the cutting blades. Be sure that all persons are clear of the mower deck and discharge area before engaging PTO.

Important: Operator must be in seat before the PTO can be engaged.

1.Set the throttle midway between the “SLOW” and “FAST” positions.

2.Pull the PTO switch outward to engage the blades.

3.Place the throttle in the “FAST” position to begin mowing.

Disengaging the PTO
