What should I do if the lawnmower stops due to overload?

If the overload protector is actuated, the motor must be allowed to cool down for 5 to 10 minutes. Turn off the power and remove the plug from the supply, then ensure the blade can rotate freely and is not jammed. When the motor is cool, reconnect, press the Start button and then the On-off button to restart — if it still will not start, return it to an authorised service centre. (Page 4)
