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.

Nailing on steel plate
WARNING:
When nailing on the C-shaped
steel, limit the thickness to 2.3 mm (3/32") or
thinner. Otherwise the tool will bounce severely and
a nail struck back, causing serious injuries.
WARNING:
Use hardened nails only for steel
plate. Using other purposed nails may cause serious
injuries.
When nailing, hold the tool so that
WARNING:
it stands upright to the driving surface. Slanted
nailing may cause nails to strike back, causing seri-
ous injuries.
WARNING:
Do not use the tool for fastening
a corrugated plate or the C-shaped steel directly.
It may cause nails to strike back, causing serious
injuries.
WARNING:
Do not use the tool for nailing on
ceiling or roof.
Choose and use nails 10 mm (3/8") or much longer than
total thickness of all workpiece to be fastened. Refer to
the table below.
