DeWalt 140 - Page 5

This saw has been carefully tested and inspected at the
factory. Do not change adjustments until careful inspec-
tion indicates this is necessary.
Occasionally in shipment . . . or after the saw has been
used for some time . . . or if the mitre gauge or fence has
been dropped ... the settings may come out of alignment
and inaccuracies will occur in the work. When this hap-
pens it's easy to make the proper adjustments by following
the i nstructions as outlined below.
I. Keep the Blade Sharp and Properly Set -
A sharp blade is essential for fast free cutting. When blade
pounds; when stock burns, is hard to push grabs or
creeps, it 's an indication the blade is dull or has lost Jts
set. A dull blade may damage the saw or motor an<i in-
jure the operator. Figures 21 and 22 show the properly
sharpened blade and the blade that is dull or improperly
set. KEEP THE BLADE SHARP for all around efficiency.

The illustrations above show the cutting tooth form for a
crosscut and a combination blade - a rip blade differs only
in that the teeth are flat on top with no bevel.
NOTE: The raker teeth on a combination blade (see
drawing in insert above, le/ t) are fiat on top with no set .
2. Adjusting Fence Parallel to Saw Blade -
