FLEX Tri-Glide Foot Adjustment:
Wood varies from one manufacturer to the next. The
different wood profiles may be due to height and
length of the flooring tongue and whether or not there
is a nail pocket.
To use the Powernail 50P Flex, adjust the nailer FLEX foot to a sample of your flooring (see instructions below).
When the nailer foot is adjusted to your flooring, simply place the nailer on the floor and pull nailer back so the
triangles (Figure 2) catch the edge of the floor above the tongue. Hit the plunger with the rubber-capped mallet-end
to let the Nailer drive and set the nail at the correct 45 degree angle.
First, loosen the two hex bolts under the FLEX foot with
the Allen Wrench supplied with the nailer. (Figure. 1.)
Next, set the nailer on a sample of your flooring
Use the adjustment lever at the back of the nailer foot to
raise or lower the nailer to the wood.
Match the Adapter Foot Triangles so that it is pointing
into the 90° angle created
by the tongue and the top of the wood (see Figure 2).
For wood with a nail pocket, line up the Triangles at the
top of the nail pocket.
When the adjustment lever is in the correct position
for your wood sample, tighten the two hex bolts to
lock the FLEX foot into place.
Always check your adjustment with a sample to
ensure the nail is driving into the nail pocket.
