(4) Other Precautions on Reassembly
(a) On completion of reassembly, set the Shift Knob [16] to the "H" position, and confirm that the spindle
rotates smoothly when the Drill Chuck [8] is moved by hand. Also, before turning the switch ON, confirm
that the Cap [9] can be properly aligned with the clutch number positions, marked on the Housing (A),(B)
Set [3].
Confirm that the Drill Chuck [8] rotation conforms with the setting position of the reversing switch. When
the reversing switch is set to the (R) side, the Drill Chuck [8] must rotate to the right (clockwise) when
viewed from the rear (the end opposite from the drill chuck).
Also, confirm that the rotation speed of the Drill Chuck [8] changes properly between high and low speeds
when the Shift Knob [16] position is changed.
Check the run-out of the Drill Chuck [8]. With a 6 mm test bar (Special Repair Tool J-223-2, Code No.
305713) mounted in the Drill Chuck [8], ensure that run-out is not more than 0.5 mm when measured at a
distance of 50 mm from the end of the chuck.
