Installing Or Removing The Blade - RIDGID MS1250 Manual Del Operador

Installing or Removing the Blade

WARNING: To reduce the risk of
injury from a thrown workpiece
or thrown pieces of blade, do not
use a blade larger or smaller than
12" diameter.
WARNING: To reduce the risk of
injury from unexpected starting,
unplug the saw whenever you
are removing or installing the
blade.
1. Unplug the saw from the outlet.
2. Rotate the lower plastic guard by
hand. Loosen, but do not remove, the
cover plate stop screw using the Phil-
lips end of combination wrench.
3. Lift the lower guard up and tilt the
lower guard assembly back so the
arbor screw is exposed.
4. Find the arbor lock between the upper
guard and the miter saw handle. Fit 1/
4" hex end of combination tool in arbor
screw or use 1/2" box end wrench.
5. Press the arbor lock and hold it in
firmly while turning the wrench clock-
wise. The arbor lock will engage after
some turning of the wrench.
NOTE: The arbor screw has a left hand
thread. This helps prevent unwanted
loosening of the arbor screw during nor-
mal operation.
6. Remove the arbor screw, arbor washer,
outer blade collar, and the blade.
NOTE: Pay attention to pieces removed,
noting their position and direction they
face (see illustration). Wipe the blade col-
lars clean of any sawdust before installing
the new blades.
CAUTION: To reduce the risk of
cuts from extremely sharp teeth:
Wear gloves when installing or
removing sawblade.
See cautions in "Using Carbide Tipped
Blades" section concerning inspection,
use, and selection of carbide tipped and
other sawblades.
