  12. Continuous motor operation stops after the 2nd operating time (10 ± 2 sec.).
  13. The motor does not operate for the 2nd cooling time (18 ± 2 sec.).
  14. The motor repeats the 2nd operating time and 2nd cooling time while motor operation continues.
    A. If the motor does not operate continuously, the operating time is increased.
    B. The motor operating time resets to "0" if the battery or fuse is reconnected after being disconnected, discharged, or blown.
