Install/Remove The Blade - RIDGID R4251 Operator's Manual

INSTALL/REMOVE BLADE
A 12 inch Blade is the maximum Blade
capacity of the Saw. Larger Blades will come in contact with
the Blade Guards.
See Figure 8.
1.
Make sure the Saw is unplugged.
2.
Raise the Saw Arm to the full upright position.
3.
Rotate the Lower Blade Guard (F13) up to expose the
Blade Bolt (A). Hold the Lower Blade Guard with the
Right thumb, and press the Spindle Lock Button (F15)
with the Right index finger at the same time.
4.
If replacing the Blade, carefully rotate the blade until
the spindle locks in place.
See Figure 9.
NOTE: To aid blade change, raise the lower guard and loosen
the blade bolt cover screw a few turns to hold the lower guard
up.
NOTE: Securely tighten the screw back in place when
completing the blade change.
5.
Using the supplied Blade Wrench, remove the Blade Bolt
(A) by turning it clockwise.
NOTE: The Blade Bolt has left-hand threads.
6.
Remove ONLY the Outer Blade Washer (B) and the
Blade (F12), leaving the Inner Blade Washer on the
Spindle. See Figure 9.
7.
Carefully fit Saw Blade inside the Blade Guard and guide
it onto the Spindle, ensuring the Teeth of the Blade are
facing down at the front of the Saw.
8.
Align the double "D" Flats on the Blade Washer (B) with
the flats on the Spindle and fit the Washer onto the
Spindle.
9.
Lock the Spindle by depressing the Spindle Lock Button.
Screw in the Blade Bolt (A), remembering to thread it
counterclockwise. Tighten Blade Bolt securely using the
provided Blade Wrench.
ALWAYS install the Blade with the Blade
Teeth and the arrow on the side of the Blade pointing down at
the front of the Saw. The direction of the Blade rotation is also
stamped with an arrow on the Upper Blade Guard.
10.
Raise and lower the Saw Arm to ensure that the Arm
and Blade Guard move freely.
Make sure the Spindle Lock Button (F15),
see Figure 8, is not engaged before reconnecting Saw to
power source. NEVER engage Spindle Lock button when Blade
is rotating.
NOTE:
Some illustrations in this manual indicate ONLY
portions of the Saw. This is done in order to more clearly show
key areas and components of the Saw. NEVER operate the
Saw without all Guards securely in place and in good operating
condition.
