Setup (Installation)
The ACTIVLIFE ignition key is a direct replacement part. No complex installation is required. Follow these steps:
- Verify Compatibility: Before use, ensure that your Scag Turf Tiger II mower is one of the specified models (STTII-61V-37BV-EFI or STTII-72V-37BV-EFI).
- Inspect the Key: Visually inspect the new key for any manufacturing defects or damage.
- Insert into Ignition: Gently insert the key into the ignition switch of your mower. Do not force the key if it does not slide in smoothly.
If the key does not fit, double-check the mower model and contact the seller for assistance.
Operating Instructions
To operate your Scag Turf Tiger II mower using the ACTIVLIFE ignition key:
- Safety First: Always ensure the mower is in neutral, the parking brake is engaged, and all safety precautions outlined in your mower's primary user manual are followed before attempting to start the engine.
- Insert Key: Insert the ACTIVLIFE ignition key fully into the ignition switch.
- Turn to START: Turn the key clockwise to the 'START' position. Hold it there until the engine starts, then release it. The key will spring back to the 'ON' position.
- To Stop Engine: Turn the key counter-clockwise to the 'OFF' position. Remove the key when the mower is not in use to prevent unauthorized operation.
Maintenance
Proper care of your ignition key will ensure its longevity and reliable performance:
- Keep Clean: Periodically wipe the key with a dry cloth to remove dirt, dust, or debris. Avoid using harsh chemicals or abrasive materials.
- Avoid Damage: Do not bend, scratch, or modify the key. Store it in a safe place where it will not be exposed to excessive force or extreme temperatures.
- Lubrication: Do not lubricate the key itself. If the ignition switch feels stiff, consult your mower's manual for recommended maintenance of the ignition switch.
Troubleshooting
If you encounter issues with your ACTIVLIFE ignition key, consider the following:
- Key Does Not Turn: Ensure the key is fully inserted. Check for any obstructions in the ignition switch. Do not force the key.
- Engine Does Not Start: If the key turns but the engine does not start, this may indicate an issue with the mower's ignition system, battery, or fuel supply, not necessarily the key itself. Refer to your Scag Turf Tiger II mower's primary user manual for engine starting troubleshooting.
- Key Appears Damaged: If the key is bent, broken, or shows signs of wear that prevent it from functioning, it should be replaced.
For persistent issues, consult a qualified service technician or contact the seller.
