4) Apply silicon to the thread of the screw removed in (1), and then put the screw back into its original place.
Caution: x Do not use spray oil when applying grease. Be sure to use spray grease instead. Keep the
spraying time to within 1 second, and do not spray continuously for more than 1 second or spray
more than twice repeatedly. Also note that if an excess amount of grease is supplied, oil may
flow into the electronic components and cause malfunction.
x In case the grease got into your eye, immediately go see the doctor to get appropriate care.
After finishing the grease supply work, wash your hands carefully with water and soap to rinse
the grease off.
