Assembly and adjustments (continued)
Blade removal and installation (Fig. 13-15)
WARNING: To prevent personal injury, always turn saw OFF and disconnect the plug
from the power source before changing blades or making adjustments.
This saw uses pin-end and pinless blades. Pin-end blades
are thicker for stability and for faster assembly. They
provide faster cutting on a variety of materials.
Note: When installing pin-end blades, the slot on the blade
holder must be slightly wider than the thickness of the blade.
After the blade is installed, the blade tension mechanism
will keep it in place.
1. To remove the blade, loosen the tension on it by
lifting up and turning the blade tension lever (1)
counterclockwise.
2. Remove the table insert. Carefully pry up on the table
insert and remover.
3. Loosen the upper blade holder knob (2) and lower
blade holder knob (3). Push down on the upper blade
holder to remove the blade from the holder. Remove
the blade from the lower blade holder.
CAUTION: Install the blade with the teeth pointing
downward.
4. To install the blade, hook the blade in the recess of the
lower blade holder.
5. While pushing down on the upper blade holder, insert
the blade into the slot of the holder.
6. Tighten the upper and lower blade holder screws.
7. Move the blade tension lever down and turn the blade
tension lever (1) clockwise until you feel the slack in
the blade removed. Make sure the blade is properly
located in the blade holders. Turn the blade tension knob an additional one full turn
clockwise. This amount of blade pressure should do well for most cutting operations.
8. Snap the table insert back into place.
