 Application: petrol lawn mowers — walk-behind and ride-on
 Electrode configuration: single center electrode with ground electrode
 Heat range: suitable for standard mower operating temperatures
How to use
Ensure the engine is switched off, cooled down, and the ignition system is disabled before replacing the spark plug. Remove the spark plug cap and use a spark plug socket to unscrew the old plug. Check the new NAC spark plug for correct electrode condition and set the gap if required to the engine manufacturer's specification. Hand-thread the new plug to avoid cross-threading, then tighten to the recommended torque. Reconnect the spark plug cap securely and test-start the engine to confirm proper ignition and running.
Usage recommendations
Replace the spark plug at regular intervals as specified by the mower manufacturer or when signs of poor starting, misfiring, or excessive fuel consumption occur. Use the correct gap and torque settings, and inspect the ignition lead and boot for wear when servicing. For best results, pair replacement spark plugs with clean air filters, fresh fuel, and routine carburetor checks.
