6. WHEN USING THE METAL PLATE NAILS
●
Carry out construction work based on the Construction Standards.
●
When there are no construction criteria specified, see a reference construction example.
●
Never use for the ceiling (ceiling groundwork included) and roof (roof groundwork
included).
●
Be sure to apply the nose of the ejection port to the member at a right angle.
●
Do not drive 38- to 50-mm nails directly.
This machine is specially designed for 1.6- to 3.2-mm-thick light gage steel. When using it, consider
the member material and field conditions to comply with the Construction Standards.
WARNING:
CRITERIA FOR SELECTING THE NAIL LENGTH FOR METAL PLATES
q
Select the nail length at least 10 mm longer than the total thickness of each member.
w
The groundwork material used for the light gage steel should be 3.2 mm or less, and
the exterior members such as sheet zinc should be 0.7 mm or less.
e
Never drive 38- to 50-mm nails directly to the light gage steel, because they will fly
off, endangering you very much.
r
Be sure to apply the nose of the ejection port to the member at a right angle. If
applied obliquely, the nails will fly off, endangering you very much.
t
Never use for the roof (roof groundwork included) or ceiling (ceiling groundwork
included).

WHEN USING THE CONCRETE NAILS
This apparatus is specially designed for the concrete which has been just placed.
When using it, consider the member material and field conditions to comply with the
Construction Standards.
●
Select the nail length so that its penetration depth into the concrete will be 10 to 15
mm.
※
If the penetration depth into the concrete is 15 mm or deeper or the concrete is hard,
the nails may not be driven.
Wood
y
Too much driving to the metal plate reduces a holding force extremely. Check the
driving circumstances fully prior to work.
※
The nails may not be driven depending on the combination of the hardness and
thickness of the members.
