11. The pressure gauge on the right side of your stretching machine indicates

regulated air pressure to the "stretching plates". It is a safe practice to always

start a stretch at around 15 – 20 psi this is accomplished with the

Stretcher Bar Regulator.

12. If you need more pressure you can always increase stretching pressure. Do not

"overstretch", a tight stretch can be obtained with only 20-30 psi provide you

have a stretcher bar with a nice radius. Stretcher bars should always have a

pronounced radius, the harder the edge the harder it is to get the canvas to

stretch.

13. When you are satisfied with the tension you can staple the canvas to the frame

with a long-nosed pneumatic staple gun. The staple gun is operated upside down

and the trigger is depressed with the thumb. Slide the nose of the staple gun

along the angle bar beneath the stretcher frame. Place a staple at least 1 every

inch.

14. Release the stretch by stepping on the stretching pedal. Depress the clamping

foot pedal again to open the clamp and remove the artwork. Rotate the artwork

90 degrees; use the deck of your machine and the work surface to support the

artwork. This is how you stretch each end.

15. You are now faced with the decision to fold the corners and continue stretching

or cutout the excess canvas and then stretch. Removing the excess canvas is the

recommended method and provides the best results.
