Assembly; Removing Or Installing The Blade - RIDGID MS1050 Owner's Manual

Assembly

WARNING: For your own safety, never connect
plug to power source outlet until all assembly
steps are complete, and you have read and under-
stood the safety and operational instructions.

Removing or Installing 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 10" diameter.
WARNING: To reduce the risk of injury from unex-
pected starting, unplug the saw whenever you are
removing or installing the blade.
1. Unplug the saw from the outlet.
2. Loosen the cover plate stop screw with phillips end of
the supplied combination wrench.
3. Lift the lower guard up and rotate the cover plate back
so the arbor screw is exposed.
4. Find the arbor lock between the upper guard and the
miter saw handle. Press the arbor lock and hold it in
firmly while turning the arbor screw. The arbor lock will
engage within one half revolution of the blade.
NOTE: For an alternate locking means, you may lower
the blade down onto a scrap piece of wood positioned
against the fence.
5. Place the 1/4" hex end of combination wrench supplied
into the arbor screw. Turn the "L" wrench clockwise to
loosen the arbor screw. Remove the arbor screw, outer
blade collar, and the blade.
NOTE: Pay attention to pieces removed, noting their
position and direction they face (see illustration). Wipe
the blade collars clean of any sawdust before installing a
new blade.
6. Install the new 10" blade (see "Basic Blade Require-
ments" and "Using Carbide Tipped Blades" section).
Make sure the rotation arrow on the blade matches the
clockwise rotation arrow on the upper guard.
7. Install the outer blade collar and arbor screw. Turn the
allen wrench counter clockwise to secure the blade.
Tighten arbor screw securely.
8. Lower the lower blade guard until the slot in cover plate
rests all the way down on the coverplate stop screw.
Tighten the screw.
DANGER: Never use saw without cover plate
securely in place. It keeps the arbor screw from
falling out if it accidentally loosens, and prevents
the spinning blade from coming off the machine.
9. Be sure the arbor lock is released so the blade turns freely.
NOTE: The arbor lock can be damaged by improper use.
WARNING: Make sure the collars are clean and
properly arranged. After installing a new blade,
make sure the blade clears the table slot at the 0°
and 45° bevel positions. Lower the blade into the
lower table and check for any contact with the
base or turn table structure.
10. After changing the blade place the 1/4" hex wrench in
the handle/storage area.
