Possible causes
• Arrow light turns off after 3 minutes of motor inactivity.
Press momentary button to turn light back on
8 HARD TO UNLATCH MOUNT FROM THE RUN OR
STOW POSITION WHEN USING PULL ROPE.
• Your bow mount is designed to easily release with a quick
pull of the rope handle. If it does not, it is almost always
due to the improper installation of your bracket. What
usually happens is that your bracket does not rest evenly
on the isolators before you tighten it down. Once
tightened, the bracket binds up, causing the latch to not
function properly. You can test this by loosening the screws
slightly (start with the two forward screws) and latching the
bracket. You will usually find the problem area by
alternately trying each screw until the bracket releases
easily. The final step is to install additional shim washers
(provided) and then re-tighten the screws.
Apply a general purpose grease to the latch pins and
grooves periodically.
