Position the frame so that it is against the “mechanical stops”, the short tab of metal about
1/8” high (these stops also facilitate alignment during the stretch). Loosen the (4) screws
on each of the slotted stretcher plates.
Apply air to your machine and verify that the clamping bar is open. Move the assembled
frame and the plates
together
in and out until the face of the wooden frame is
approximately
½
” behind the angle bar. In other words, create a gap so the canvas will
“waterfall” down into the opening when the clamp is closed. This step (above and below)
is simulated without the canvas present.
Tighten all of the screws. This setting will not change for any stretcher bar that is this
width. This procedure would only need to be done again if you change to a different
width of stretcher bar.
This is referred to as the “Loaded Position”
