Pushing Button [39] is pressed from the (R)-marked side, the Drill Chuck 13VLRF-N (W/O Chuck Wrench)
[2] should turn clockwise when viewed from the rear (opposite side of the Drill Chuck 13VLRF-N (W/O
Chuck Wrench) [2]). Also make sure that the turning speed of the Drill Chuck 13VLRF-N (W/O Chuck
Wrench) [2] switches between "HIGH" and "LOW" by switching over the Shift Knob [41]. Make sure that
the run-out of the Drill Chuck 13VLRF-N (W/O Chuck Wrench) [2] holding a 12 mm dia. test bar is below
0.8 mm at a distance of 110 mm from the chuck end.
