ASSEMBLY
Installing Blade (Fig. H, I, J, K)
Unplug the miter saw before changing/installing the blade.
1. Install a 10 in. blade, making sure the rotation arrow on the
blade matches the clockwise rotation arrow on the upper
guard and the blade teeth are pointing downward. (Fig. K).
2. Place the outer blade collar (6) against the blade (7) and
on the arbor. Thread the arbor bolt (4) onto the arbor in a
counterclockwise direction. (Fig. K)
IMPORTANT: Make sure the flats of the blade collars are
engaged with the flats on the arbor shaft.
3. Place the blade wrench on the arbor bolt (4).
4. Press the arbor lock (5), holding it in firmly while turning
the blade counterclockwise. When arbor lock engages,
continue to press it in while tightening the arbor bolt
securely. (Fig. J)
5. Lower the blade guard (1) and rotate the cover plate (3)
back to its original position until the slot in the cover plate
engages with the cover plate screw (2). (Fig. H)
6. Tighten the screw (2) with a Phillips screwdriver.
7. Verify that the operation of the blade guard (1) does not
bind or stick. (Fig. H)
8. Be sure the arbor lock (5) is released so the blade turns
freely. (Fig. J)
WARNING
• To avoid injury, never use the saw
without the cover plate secure in place. It keeps the
arbor bolt from falling out if it accidentally loosens, and
helps prevent the spinning blade from coming off the
saw.
• Make sure the collars are clean and properly arranged.
Lower the blade into the lower table and check for any
contact with the base or the miter table by spinning the
blade manually.
MOUNTING THE MITER SAW (FIG. L, M, N)
WARNING
To avoid injury from unexpected saw
movement:
• Before moving the saw, disconnect the power cord
from the outlet, and lock the cutting arm in the lower
position using the head lock down knob.
NOTE: The head lock down knob is for carrying or storing the
tool. It is not to be used for holding the saw while cutting.
Lower blade and press in head lock down knob to secure saw
for transport or storage.
• Never carry the miter saw by the power cord or by the
switch handle. Carrying the tool by the power cord could
cause damage to the insulation or wire connections
resulting in electric shock or fire.
• To avoid injury from flying debris, do not allow visitors to
stand behind the saw.
• Place the saw on a firm, level worksurface where there is
room for handling and properly supporting the workpiece.
• Support the saw on a level work surface.
• Bolt or clamp the saw to its support.
Place the saw in the desired location, either on a work bench
or recommended leg set. The base of the saw has
four mounting holes (10). (Fig. M)
Mounting instructions:
1. For stationary use, place the saw in the desired location,
directly on a workbench where there is room for handling
and proper support of the workpiece. The base of the saw
has three mounting holes. Bolt the base of the miter saw
(1) to the work surface (5), using the fastening method as
shown in Fig. L.
1. Miter saw base
2. Hex head bolt
3. Rubber washer
4. Flat washer
5. Work surface
6. Flat washer
