Checking proper action before
operation
Before operation, always check following points.
— Make sure that the tool does not operate only by
connecting the air hose.
— Make sure that the tool does not operate only by
pulling the trigger.
— Make sure that the tool does not operate only by
placing the contact element against the workpiece
without pulling the trigger.
— In single sequential actuation mode, make sure
that the tool does not operate when pulling the
trigger first and then placing the contact element
against the workpiece.

Single sequential actuation
CAUTION:
Do not place the contact element
against the workpiece with excessive force. Also,
pull the trigger fully and hold it on for 1-2 seconds
after nailing.
Even in the "Single sequential actuation" mode, half-
pulled trigger causes an unexpected nailing, when the
contact element re-contacts the workpiece.
Place the contact element against the workpiece and
pull the trigger fully.
After nailing, release the contact element, and then
release the trigger.
