Notations and Conventions
Call-Outs
Tools Required:
• open-blade hand saw, such as a keyhole saw or mini
hacksaw, with an exposed blade length of at least
3 inches (7.6 cm);
• basic hand tools including groove-joint or similar
wide-jaw pliers for closing ratchet ties; and,
• a knife or similar tool for de-burring the inside edges of
the cut tubes.
Read the installation manual entirely. When you see
this symbol, the subsequent instructions and warnings
are serious - follow without exception. Your life and
the lives of others depend on it
a. The 2012+ screen is conical, rather than cylindrical. This improves resistance to seed bridging in the screen.
