◊ BLADe TrACKInG
1. Turn the upper wheel by hand to check blade tracking
on the wheel tires. Blade should be relatively centered
on both upper and lower wheels.
2. To adjust blade tracking, loosen the lock nut behind the
tracking adjustment knob, located behind the upper
panel.

◊ BLADe rePLACeMenT
1. Release blade tension by lifting blade tension handle.
It might be necessary to turn the handle counterclock-
wise for the blade to be loose enough to be removed
easily. Do not over loosen blade tension mechanism
to avoid disconnecting the tension.
2. Remove the table alignment pin from the table slot.
3. Remove the table insert and open both access doors.
4. Move the upper and lower guide blocks and thrust
bearings away from the blade.
5. Remove the blade by pulling the left side first and then
slide the right side through the table slot. Be careful not
to have the teeth rubbing against metallic surfaces.
Wearing safety glasses and gloves is
recommended .
6. Working the reverse steps, install the replacement blade.
Make sure the teeth are facing down on the right side of
the wheel. Reinstall the alignment pin in the table slot.
◊ BLADe TensIon
1. With the blade positioned in the center of the wheels,
lower the tension handle. The handle is excentrically
mounted to generate blade pull effect and compresses
the tension spring.
To increase the tension, turn the lever (in vertical
position) in clockwise direction. To reduce tension, turn
in counterclockwise direction. Lower handle to apply
tension and check if setting is appropriate. Never turn
the tension handle while it is in downward position,
as you may break the tension spring.

To prolong the life of the blade and the spring, if the
bandsaw is not in use for an extended period of time
(over 24 hrs), release the blade tension by lifting the
handle and disconnect power.
ADJUsTMenTs
We will do a blade replacement to show the various
adjustments required.
2. Move the upper guide block assembly to its highest
point.
3. With the saw turned off, check tension by pressing
against the side of the blade, halfway between the guide
block and the table. The blade should not flex more than
about 2 mm (5/64’’).
NOTE : Too much tension will make the blade break
prematurely and will be more difficult to use for tight radius
cuts. With insufficient tension, the blade will have tendency
to drift when cutting, might slip on the lower wheel so blade
stops cutting and will give poor cut quality.
To move the blade toward the inside, turn the knob
clockwise. To move the blade toward the outside, turn the
knob counter clockwise. Turn the wheel by hand to move
the blade and confirm the tracking. Lock the knob in
position by tightening the lock nut.
Make sure the switch is in the off position and
the machine is unplugged.
