2.Motor can be operated continuously for the 1st run-time (120 ± 10sec.).

3.The continuous operation of motor stops after the 1st Run-time (120 ± 10sec.).

4.Then Motor is not operated for the 1st Cool-time (18 ± 2sec.).

5.Motor is operated for the 2nd Run-time (10 ± 2sec.) at the continued motor operation after 1st Cool-time (18 ± 2sec.)

6.The continuous operation of motor stops operating after the 2nd Run-time (10 ± 2sec.)

7.Motor is not operated for the 2nd Cool-time (18 ± 2sec.).

8.Motor repeats the 2nd run-time and 2nd cool-time at the continued motor operation.

– In case that motor is not operated continuously, the run-time is increased.

– The Run-Time of motor is initialized to "0" if the battery or fuse is reconnected after being disconnected, discharged or blown.
