TROUBLESHOOTING
Electric machines prefer to run at a constant speed� If you encounter some heavy / thick grass that slows the motor down, slow down the forward
motion to allow the motor to run back up to its normal operating speed�
The electronic speed controller within the Masport smart lawn mower has been design to protect itself from damage by only operating within a safe
operating zone� If you cut some particularly long / dense grass (first cut of the season etc�) the controller may get warm to the point that it will protect
itself by switching off the motor� No worries, it will allow the motor to operate again after it has cooled down� This is not a fault; it is by design to provide
you with a long term reliable product�
The same is true of a separate electronic controller built into the Lithium Ion Battery pack and coupled with another one built into the smart charger� They
have been designed to work in unison to protect the high performance Lithium Ion Battery, resulting in a long trouble free operating life and providing
the optimum charge every time� In achieving this, the controller may sometimes prevent the battery from being charged if the previous run resulted in an
overly warm battery pack� Waiting a brief period after cutting the grass before putting the machine on charge will allow the battery pack to cool down
to enable it to receive a full fresh charge� These smarts have been incorporated to protect the various items from damage and provide the user with a
reliable long term product�
To allow the free running of the motor, do not cut with an excessively low cut height� Two light cuts are better than one heavy cut especially when not
using the catcher�
