CUTT,A'G DEPTH ADJUSTMENT

T H I S O R A N Y O T H E R A D J U S T M E N T .
For the most efficient cutting action, set the Depth Adjustment
so that one tooth of the blade will project below the material to
be cut. This distance is from the tip of the tooth to the bottom
of the gullet in front of it. This keeps blade friction at a mini'
mum, removes sawdust from the cut, and results in cooler,
faster sawing.
NOTE: When using Carbide-Tipped Blades, make an exception
to the above rule and allow only one'half of a tooth to proiect

for sawing thin plywood.
