on the surface of workpiece. Holding it too upright
tends to cause a breakage of workpiece.
Inflation or breakage on the stapled spot of
•
workpiece of workpiece may occur depending on
many stapling conditions, even when stapling
holding the tool at the specified angle. Try on
some test samples before actually stapling.

In stapling requiring accuracy, such as flooring, use in
the "Intermittent stapling" mode
When stapling, hold the tool tilting it at the angles 50° -
55°shown in the figure.
