INSTALLING OR REMOVING THE BLADE

■

Unplug the saw from the outlet. Cutting head is up.

■

Rotate the lower blade guard (2) by hand. Loosen,
but do not remove, the cover plate screw (4) using
the Phillips end of combination wrench.

■

Lift the lower guard up and tilt the lower guard
assembly back so the arbor screw (27) is exposed.

■

Fit 6.35 mm hex end of combination tool in arbor
screw or use 12.7 mm box end wrench.

Note:

The arbor screw (27) has a left hand thread.

This helps prevent unwanted loosening of the arbor
screw during normal operation.

■

Remove the arbor screw, arbor washer (31), outer
blade flange (30), 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 the new blades.

CAUTION

To reduce the risk of cuts from extremely
sharp teeth: Wear gloves when installing or
removing sawblade.

■

Install the new 305 mm blade. Make sure the rotation
arrow on the blade matches the clockwise rotation
arrow on the upper guard. The blade teeth should
always point downward at the front of the saw.

■

Install the outer blade flange, arbor washer and
arbor screw. Press the arbor lock and turn the
combination wrench or the 12.7 mm wrench counter
clockwise to secure the blade. Tighten arbor screw
using moderate force, but do not overtighten.

■

Lower the lower blade guard until the slot in cover
plate rests all the way down on the cover plate stop
screw. Tighten the screw with the Phillips end of the
combination wrench.

DANGER

Never use saw without guard 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.

■

Be sure the arbor lock is released so the blade
turns freely.

Note:

The arbor lock can be damaged by improper use.

If the arbor lock will not hold, lower the blade down on
to a scrap piece of wood positioned against the fence.
This will serve as an alternate lock-ing means.

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 table
slot and check for any contact with the base or
turn table structure. If blade contacts table, seek
authorized service.

If blade contacts insert, refer to “Alignment“ section for
adjustment.

WORKPIECE CLAMP INSTALLATION (FIG. 3)

The workpiece clamp (23) is used to help hold the
workpiece in the correct cutting position. It may be used
on either the left side of the miter saw or the right side.
Before turning the saw on make sure the workpiece clamp
does not interfere with the cutting action of the saw.

■

Align clamp shaft (32) with hole in base. Insert
clamp shaft.

FOUR BASIC SAW CONTROLS

In order to properly adjust and align the Sliding
Compound Miter Saw there are four basic controls that
must be understood.

■

Miter lock lever and miter index wheel (Fig.4)
to change the miter setting of the blade:

- Raise the miter lock lever (15).

- Rotate the miter index wheel (34) partially

downward to disengage the current index and
engage the next index.

- Rotate the miter index wheel completely downward

to bypass all miter indexes.

- Turn the table (6) to the desired miter setting and
