PIN-END BLADE INSTALLATION ( FIG. M, N )
NOTE: Do not tighten the lock knobs when using Pin-
end blades.
WARNING
In order to avoid uncontrollable lifting of the
workpiece, the teeth of blade should always point
downward.
1. Install the blade (1) by inserting one end of it through
the access hole (6) or throat plate in the table. Hook
the lower blade pin in the pin recess in the lower
blade holder (5) and then the upper blade pin in the
upper blade holder (4). (Fig. M)
Fig. M
2. Make sure the pins are properly located in the upper
(4) and the lower (5) blade holders.
3. To tension the blade (1-Fig. M), lower the quick
release tension lever (1). Check the tension on
the blade. If tension is too tight, turn the knob (2)
counterclockwise. If tension is too loose, turn the
knob (2) clockwise (Fig. N).
NOTE: If the blade is over-tightened, the lever will be
difficult to lower and could result in damage to the
blade holder or arm assembly.

PIN-END BLADE REMOVAL AND INSTALLATION
WARNING
To prevent personal injury, always turn the saw OFF
(O) and disconnect the plug from the power outlet
before changing blades or making adjustments.
Pin-end type blades are thicker for stability and faster
assembly. These blades are used whenever faster
cutting on a variety of materials and 3/4 in. thickness or
greater are required. Use whenever less precision or
thicker kerf cutting is acceptable.
NOTE: When installing Pin-end blades, the set screws
located on the upper and lower blade holders should
not be over or under tightened. The slot must be slightly
wider than the thickness of the blade. After the blade
is installed, the blade tension mechanism will keep the
Pin-end in place.
PIN-END BLADE REMOVAL (FIG. K, L)
1. To remove the blade, loosen the tension by lifting the
quick release tension lever (2). (Fig. K)
Fig. K
2. Remove the blade (1) from the upper (4) and lower
(5) blade holder by pulling forward to release, and lift
the blade through the access hole. (Fig. L)

3. Tilt the table to a 45° angle and lock the bevel lock
knob to view lower blade holder (5) for removing the
