Electronic motor

Use the "Speed" selection keys to set the speed of the electronic motor to its maximum. With the 1:1 Contra

The electronic motor is designed for an intermittent duty operation at maximum speed of "1 min ON/3
min OFF" at 4 cycles. Brake after 15 min. Otherwise the electronic motor can be damaged by excessive
heat generation, and by touching the motors hull it could cause serious burnings.
The motor ventilation slots must be kept clear in order to prevent the motor temperature from
becoming excessive.
