OPERATION (CONTINUED)
4. Loosen the blade tension by turning the blade tension knob on
the top of the upper wheel housing counterclockwise until the
saw blade has slackened (viewed from above). See Figure 12.
5. Remove the saw blade from the upper and lower wheels.
When fitting the new saw blade ensure the blade teeth are pointing
downwards and towards you at the position where the saw blade
passes through the table.
6. Re-tension the new saw blade and check the saw blade tracking
by turning the upper wheel by hand.
The saw blade should run in the center of the band saw wheels. If
needed adjust the tracking of the saw blade, follow procedures for
"Tracking the Saw Blade".
7. Tighten the tracking lock knob.
8. Replace the rip fence, the guide rail, the wing nut and screw to
the table.
9. Close the upper and lower doors by turning the door locking
knobs before reconnecting the power supply.
TRACKING THE SAW BLADE
Refer to Figure 13.
Set the tracking of the saw blade before setting the blade guides.
1. Once the saw blade is installed and tensioned, track the saw
blade by adjusting the tracking knob by hand.
2. The saw blade should run in the center of the band saw wheels.
3. When the correct adjustment is achieved lock the tracking knob
with the tracking lock knob.
SETTING THE CUTTING HEIGHT
Refer to Figure 13.
The upper blade guide should be set as close as practical against
the workpiece.
1. To adjust this height, loosen the guide post lock knob at the side
of the upper wheel housing.
2. Set the blade guide to the required height by turning the guide
post adjusting knob.
3. Tighten guide post locking knob after setting.
ALIGNING THE UPPER BLADE GUIDE
The upper blade guide consists of:
• A thrust bearing (supporting the band saw blade from the rear).
• Two guide bearings (providing lateral support).
All bearings need to be readjusted after every band saw blade
change and/or tracking adjustment.
NOTE:
Periodically check all bearings for wear, if necessary replace
both guide bearings at the same time.
ADJUSTING THE THRUST BEARING
Refer to Figure 14.
1. If necessary, align and tighten the band saw blade.
2. Loosen fixing screw of the upper blade guide.
3. Align upper blade guide
4. Tighten the upper blade guide's fixing screw.
5. Loosen the thrust bearing's lock screw.
6. Adjust thrust bearing position (distance thrust bearing - band
saw blade = 0.5 mm – if the band saw blade is turned by hand, it
must not touch the thrust bearing).
7. Tighten the thrust bearing lock screw.
ADJUSTING THE GUIDE BEARINGS
Refer to Figure 15.
1. Loosen the bearing’s lock screw.
2. Set guide bearings with the screws against the band saw blade.
3. Turn band saw wheel by hand in a clockwise direction several
times to bring the guide bearings in correct position – both
guide bearings should just touch the band saw blade.
4. Tighten the bearing’s lock screw.
