9. Once the canvas is clamped and you are satisfied with the alignment move the
entire assembly forward and
off
of the plates. This is referred to as the
“un-loaded”
position. The stretcher frame should be in front of the plates and the canvas should be
held fast beneath the clamp. It is now ready to be stretched.
10. Depress the left foot pedal (
stretching pedal
). Be sure to maintain control of the
stretcher frame with your free hand. It should rest on the outside rail applying only
light pressure. The stretching pressure should be no more than 15-20 psi to start a
stretch. Increase the pressure slowly using the regulator on the right side of the
machine and let the frame rise no more than 3-4”. Do not push the frame flat against
the deck. Pushing down on the frame during a stretch will promote slipping.
“Small art tends to flip off the stretcher plates. Always keep a free hand on the rail.”
