Hanging the Shade at the Window
Roll the shade tightly by hand.
Turn the shade so the spring end of the roller is at the
left and hang it on the window.
If the spring is weak, draw the shade down about two
feet; take it from the window and roll it up by hand.
Replace it on the window and draw it down to test the
spring. Repeat if necessary until the shade runs
properly.
If the spring is too strong, roll the shade to the top of
the window; remove it and unroll the shade about two feet
by hand. Replace the shade at the window and draw it down
to test the spring.
