Changing Blades
TO INSTALL THE BLADE (FIG. 1–4)
CAUTION (DWE550 ONLY): The
inner flange has a 20 mm diameter on
one side and a 19 mm diameter on
the other. The 19 mm diameter side is
marked 19, and the 20 mm diameter
side is marked 20. Use the correct side
for the hole diameter of the blade you
intend to use. Mounting the blade on
the wrong side may result in dangerous
vibration.
1. Using the lower guard lever (k), retract the lower
blade guard (i) and place blade on saw spindle
against the inner clamp washer (o), making
sure that the blade will rotate in the proper
direction (the direction of the rotation arrow
on the saw blade and the teeth must point in
the same direction as the direction of rotation
arrow on the saw). Do not assume that the
printing on the blade will always be facing you
when properly installed. When retracting the
lower blade guard to install the blade, check
the condition and operation of the lower blade
guard to assure that it is working properly. Make
sure it moves freely and does not touch the
blade or any other part, in all angles and depths
of cut.
2. Place outer clamp washer (n) on saw spindle
with the large flat surface against the blade and
the wording on the outer clamp washer facing
you.
3. Thread blade clamping screw (j) into saw
spindle by hand (screw has right-hand threads
and must be turned clockwise to tighten).
4. Depress the blade lock (c) while turning the saw
spindle with the blade wrench until the blade
lock engages and the blade stops rotating.
5. Tighten the blade clamping screw firmly with the
blade wrench.
NOTE: Never engage the blade lock while saw
is running, or engage in an effort to stop the tool.
Never turn the saw on while the blade lock is
engaged. Serious damage to your saw will result.
TO REPLACE THE BLADE (FIG. 2–4)
1. To loosen the blade clamping screw (j), depress
the blade lock (c) and turn the saw spindle
with the blade wrench (s) until the blade lock
engages and the blade stops rotating. With the
blade lock engaged, turn the blade clamping
screw counterclockwise with the blade wrench
(screw has right-hand threads and must be
turned counterclockwise to loosen).
2. Remove the blade clamping screw (j) and outer
clamp washer (n). Remove old blade.
3. Clean any sawdust that may have accumulated
in the guard or clamp washer area and check
the condition and operation of the lower blade
guard as previously outlined. Do not lubricate
this area.
4. Always use blades that are the correct size
(diameter) with the proper size and shape center
hole for mounting on the saw spindle. Always
