1. Disconnect Battery: Before starting, disconnect the negative (-) battery cable from the battery to prevent accidental starting or electrical shorts.
2. Locate Old Switch: Identify the existing ignition switch on your Scag equipment. Note the position and wiring connections of each terminal. It is recommended to take a photo for reference.
3. Remove Old Switch: Carefully disconnect all wires from the terminals of the old switch. Use a wrench to loosen and remove the retaining nut, then pull the old switch out from the dashboard or control panel.
4. Install New Switch: Insert the new Scag Ignition Switch Part #48798 into the opening. Ensure the switch is oriented correctly.
5. Secure Switch: Place the star washer over the threaded shaft of the switch, followed by the hexagonal nut. Tighten the nut securely with a wrench, but do not overtighten.
6. Reconnect Wiring: Reconnect the wires to the corresponding terminals on the new switch. Refer to your previously taken photo or the equipment's wiring diagram if necessary. Ensure all connections are secure and free from corrosion.
7. Reconnect Battery: Reconnect the negative (-) battery cable to the battery.
8. Test Functionality: Test the ignition switch by turning the key to different positions (OFF, ON, START) to ensure proper operation before full use of the equipment.

Operating

The Scag Ignition Switch Part #48798 functions as the primary control for starting and stopping your equipment's engine. It typically has multiple positions:

1. OFF Position: In this position, the engine is off, and all electrical circuits related to ignition are de-energized. The key can usually be removed in this position.
2. ON/RUN Position: Turning the key to this position energizes the ignition system and other necessary electrical components, allowing the engine to run once started.
3. START Position: This is a momentary position. Turning the key to START engages the starter motor to crank the engine. Release the key once the engine starts, and it will return to the ON/RUN position.

Always ensure the equipment is in neutral and all safety interlocks are engaged before attempting to start the engine.

Maintenance

The Scag Ignition Switch Part #48798 is designed for durability and requires minimal maintenance. However, periodic checks can help ensure its longevity and reliable performance:

• Inspect Wiring: Periodically check the wiring connections to the switch for looseness, corrosion, or damage. Secure any loose connections and clean any corrosion with a wire brush and electrical contact cleaner.
• Keep Clean: Keep the area around the ignition switch clean and free of dirt, debris, and moisture.
• Avoid Force: Do not force the key when turning the switch. If the key is stiff, check for obstructions or wear in the keyway.
• Terminal Condition: Ensure the electrical terminals on the back of the switch are clean and free of oxidation.
