(5) Full sequential action mechanism
Press Pushing Lever (A) [82] against
the workpiece and move the Chamber
[16] to the uppermost position. The
nailer will then operate only when you
hold down the Trigger [71]. The nailer
will not operate if you press Pushing
Lever (A) [82] insufficiently or press it
after holding down the Trigger [71].
• When holding down the Trigger [71]
after pressing Pushing Lever (A) [82]
The convex portion of the Pushing
Lever Arm [77] pushes up the Trigger
Stopper [75] and moves when the
Chamber [16] reaches the uppermost
position.
The tip of the Trigger Stopper [75]
does not prevent the Trigger [71] from
rotating (Fig. 9). Holding down the
Trigger [71] turns on the spark switch
and drives nails.
• When pressing the Pushing Lever (A)
[82] after depressing the Trigger [71]
When depressing the Trigger [71], the
tip of the Trigger Stopper [75] prevents
the Trigger [71] from rotating. Thus the
spark switch is not turned on.
