Tensioning Blade - Grizzly T31681 Owner's Manual

Tensioning Blade

A properly tensioned blade is essential for mak-
ing accurate cuts and maximizing the blade
life. However, a properly tensioned blade will
not compensate for cutting problems caused by
excessive feed rate, hardness variations between
workpieces, and improper blade selection.
Over-tensioning the blade increases the chance
of the blade breaking or wheel misalignment.
Under-tensioned blades wander excessively
while cutting and will not track properly during
operation.
Saw blades are very sharp
and can quickly cause cut-
ting injuries. Always wear
heavy-leather gloves when
handling saw blades.
To prevent blade falling off wheels and
causing injury or property damage, DO NOT
rotate blade tensioning knob when saw is
operating. Always disconnect machine from
power before adjusting blade tension.
