2. Remove the blade from the saw. See Blade
Changing Procedure.
3. Loosen the machine screws that secure the
blade wipers, remove the wipers and install
a new one.
One set of the blade wipers is located next to the
lower band wheel.
4. Install a new blade. See Blade Changing
Procedure.
5. Make sure the blade wipers are in full
contact with the blade but not contacting the
blade teeth. Adjust as required.
CHIP BRUSH REPLACEMENT
The main electrical disconnect
switch must always be turned
to the "Off" position and
locked before adjusting,
servicing or cleaning the saw.
Failure to do so can result in
serious injury or death.
The chip brush removes saw chips from the
blade to prevent them from being carried into
the band wheels and blade guides where they
can cause significant wear. It is important to
always have a functioning chip brush on the
machine.
To replace a worn chip brush:
1.
Move the saw column to the full retract
position.
2. Turn off the saw's main electrical disconnect
switch.
3. Open the lower band wheel covers.
4. Remove the nut that holds the chip brush on
the drive shaft and remove the brush.
The chip brush is held in place by a single hex
nut as shown above.
5. Install a new chip brush and secure it with
the nut.
6. Close the band wheel covers.
BLADE TRACKING ADJUSTMENT
Accurate band wheel alignment is necessary for
the blade to track correctly. If the blade does not
track correctly, blade tension will be unevenly
distributed causing the blade to crack and break.
The blade should track no more than 1/16" (1.6
mm) from the band wheel flanges.
The upper band wheel has four (4) blade
tracking adjustment screws. The screws (socket
head cap screws locked in place with hex nuts)
are positioned 90
o
apart on the upper band
wheel shaft housing. The lower band wheel is
fixed and no adjustment is needed.
To adjust the blade tracking:
1.
Make sure the blade is properly tensioned.
2. Lower the blade guard to its lowest position.
3. Open the upper band wheel doors.
