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.

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.
