Note for screwing

The screws in the kit are 

the type of screws that 

carve a slot in the plastic 

when driven in.  A #1 Philips 

screwdriver is the right size 

to use.  When screwing, 

press a screwdriver to a 

screw vertically and turn 

firmly.  The right proportion 

of the power is 70 % for 

press and 30% for turn.  A 

precision screwdriver is 

difficult to turn, so use a 

small screwdriver that has a 

grip with a diameter of 

about 2cm.
