Why my Spear & Jackson S4042X2CR Lawn Mower won't start?

If your Spear & Jackson Lawn Mower fails to operate, several factors could be the cause. The mower might be clogged; check underneath and clear any obstructions, wearing gardening gloves for protection. The battery could be the issue; ensure it's fully charged and correctly inserted. If the grass is too long, increase the cutting height and tilt the mower to reduce the initial load. Extreme temperatures can also affect battery performance, so allow it to reach room temperature. Finally, make sure the isolator key is properly fitted. Note that a short delay when starting is normal; hold the On/Off switch for 1-3 seconds.
