Operating Instructions

Starting and Stopping (D)
Make sure the blade stopped rotating before switching “on” again. Do not rapidly switch on and off.

Starting:

Press and hold the safety button 2. Squeeze the switch lever 10 towards the handle (D).
Release the safety button 8.

Stopping:
Release the switch lever 10.

Mowing (E)
For cutting convenience, it may be best to start mowing at a point close to the power supply and to work your way away from the supply. Mow the lawn at a right angle from the power supply and place the power cable to side which has already been cut(E).

Warning: When mowing do not allow the motor to labour particularly in heavy conditions. When the motor labours the speed of the motor drops and you will hear a change in the motor sound, when this occurs stop mowing, release the switch lever and raise the height of cut. Failure to do so could damage the machine.

NOTE: the motor is protected by a safety cut out which is activated when the blade becomes jammed or if the motor is overloaded. When this occurs, stop the machine and remove the plug from the power supply. The safety cut out will only reset when the switch lever 10 is released. Clear any obstruction and wait for a few minutes for the safety cut out to reset before continuing to mow At this time do not operate the switch lever 10 as this will prolong the reset time of the safety cut out. If the mower cuts out again, increase the height of cut to reduce the load on the motor.
