A WARNING: To prevent accidental starting that could cause possible serious personal injury, turn off the saw, remove the switch key, and unplug the saw before installing or removing blade.

From the back of the saw, push the lock lever counterclockwise or to the left 1/4 turn to unlock

the blade guide assembly. Use the blade guide knob to position the blade guide assembly about half way between the table and the frame.

Return the lock lever to its upright locked posi- tion. See Figures 11 and 12.

Turn the quick release knob to the left to release blade tension. Turn the tension adjusting knob to the left to lower the upper _'heal.See page 15.

Carefully remove the old blade. The spring on the upper wheel allows it to be pulled down slightly to remove the saw blade from the wheel.

Slide the new blade into the slot of the table with the teeth of the blade toward the front of the saw and facing down toward the table.

Note: The blade may need to be tumed inside out if the teeth are pointing in the wrong direction. Hold the blade with both hands and rotate it inward.

Place the blade through the lower blade guides located under the table and around the lower wheel. Pull down on the upper wheel slightly to place the saw blade on the wheel. Slowly turn the upper wheel to the right or clockwise by hand to center the blade on the rubber tires.

Adjust the blade tension and check or adjust the blade tracking. See pages 15 and 16.

Adjust both upper and lower blade guides and thrust bearings. See pages 16 and 17.

Replace the truss head screw and wing nut. Tighten securely.

Close the cover of the band saw.

_i, WARNING: Always wear safety goggles or safety glasses with side shields to protect your

eyes while uncoiling band saw blades. Failure to heed this warning could result in a serious eye injury.

Wearing gloves, carefully uncoil the blade at arms length. If the new blade was oiled to prevent rusting, it may need to be wiped to keep the oil from your workplace. Carefully wipe in the

same direction the teeth are pointing so the rag does not catch on the teeth of the saw blade.
