INSTALLING AND ADJUSTING THE
BLADE
See Figures 13 and 14.
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.
■ Open the front cover of the saw by pushing both
the upper and tower cover tabs. See Figure 6.
■ Loosen and remove the wing nut and truss head
screw from the table. See Figure 13.
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 workpiece. Carefully wipe in the
same direction the teeth are pointing so the rag
does not catch on the teeth of the saw blade.
■ Turn the quick release knob to the left to release
blade tension. Turn the tension adjusting knob to
the left to lower the upper wheel. 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 turned 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.
