Caution: While the receiver is in the
opened position, DO NOT pull the
trigger. If a battery is installed and the
fire-selector is not set at “Safe”, the
gears will “dry-spin” and potentially mis-
aligning the sector gear. The upper
receiver will not close when the sector
gear is in the wrong position, and major
hardware damages can occur if the
upper receiver is forced to close in this
situation. If you accidentally dry-spin the
gears, tap the trigger lightly until all of the sector gear’s teeth rotates inside the
lower receiver (as shown), before you attempt to close the upper receiver.
