Assembling the body
(1) Mount a rubber pin 4 to housing R, and another rubber pin 4 to housing L. See Fig. 12A
(2) When securing housing R and L with 8 pcs. of tapping screw bind PT3x16, fasten the screws with the fastening
torque of 1.1 - 1.3N.m (11 - 13 kgf.cm).
(3) When securing hammer case with 4 pcs. of tapping screw 4x25, fasten the screws with the fastening
torque of 1.76 - 2.16N.m (18 - 22 kgf.cm). The 4 pcs. of tapping screw 4x25 have to be fasened diagonally.
See Fig. 12C.
(4) When securing FET and FET spacer with tapping screw ST3x8, fasten the screw with the fastening
torque of 1.1 - 1.5N.m (11 - 15 kgf.cm). See Fig. 12B
