After reassembly as shown in Fig. 26, ensure that the Change Lever [21] is adjusted to the "hammering only"
position. Engage the claws of the Clutch [51] and the Reciprocating Bearing [53] each other. Align the wing
portion of the Lock Plate [48] horizontally and reinstall the Gear Cover Ass'y [10] so that the wing portion of
the Lock Plate [48] is contained in the rail inside of the Gear Cover Ass'y [10] . When the Second Shaft [52]
contacts the Pinion Sleeve [47] inside the Gear Cover Ass'y [10] , move the Change Lever [21] to the "rotation
and hammering" mode and rotate the Grip [3] . Then the Second Shaft [52] and the Pinion Sleeve [47] are
engaged and the end surface of the Gear Cover Ass'y [10] contacts that of the Housing [68] . At this time,
rotate the Grip [3] to check that the rotation of the Cylinder [24] is transmitted to the armature shaft.
