CAUTION!
While the receiver is opened, DO NOT touch any of the electrical connectors or the circuit board,
especially when the battery is connected as this may damage the electrical components.
CAUTION
While the receiver is opened, 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 misalign the sector gear. The
upper receiver will not close when the sector gear is in the wrong position, and major hardware
damage can occur if the upper receiver is forced to close. If you accidentally dry-spin the gears,
tap the trigger lightly until all of the sector gear’s teeth rotates inside the lower receiver.
If the fuse need to be replaced, first make sure the battery has been removed from the stock,
and the stock is in fully retracted position. Then unscrew the fuse holder compartment door as
shown to access the fuse holder.
