Tensioning Blade - Grizzly G0887 Owner's Manual

Tensioning Blade

Proper blade tension is essential to avoid blade
vibration, twist, or slippage on the wheels. A cor-
rectly tensioned blade provides long blade life,
straight cuts, and efficient cutting.
The three major signs of incorrect blade tension
are: 1) The blade stalls in the cut and slips on the
wheels, 2) the blade frequently breaks, and 3) the
bandsaw does not make straight cuts.
The blade tension failure indicator light will illu-
minate and the control panel will beep (see
Identifying Failures on Page 40) if the bandsaw
is turned ON and the tension is not set correctly.
Loosen blade tension at the end of each day
to prolong blade life.
