BLACK & DECKER CIRCULAR SAW BLADES
A dull blade will cause slow, inefficient cutting and will overload the saw motor. It is a
good practice to keep extra blades on hand so that sharp blades are available while the dull
ones are being sharpened (See "SAWS—SHARPENING" in Yellow Pages). In fact, many lower
priced blades can be replaced with new ones at very little cost over the sharpening price. USE

", 7%" or 7" BLADES, WITH %" ARBOR HOLE, ON YOUR SAW.
Hardened gum on the blade will slow down the cutting. This gum can best be removed with
trichlorethylene, kerosene or turpentine. Remove blade before cleaning to prevent solvent from
damaging plastic parts of saw.
Black & Decker manufactures a complete line of saw blades and the following types are
available.
Standard; Outstanding value for the price. These blades are also available in bulk quantities.
Ask for quantity prices. (When sold in bulk, "-01" is added to catalog number).
Premium: Industrial chrome plating gives twice the cutting life of unplated blades.
