Align the lower blade guide
The lower blade guide consists of:
- a thrust bearing (supporting the band saw blade from the rear).
- two guide bearings (providing lateral support).
These parts need to be readjusted after every band saw blade change or tracking
adjustment:
Note:
Periodically check thrust bearings and guide bearings for wear, if necessary replace
both guide bearings at the same time.
Open lower cover door and the lower blade guard.
Loosen hex bolt, move the entire lower blade guide, and adjust the guide bearing
to a position of 1 or 2 mm from bottom of individual blade.
Adjusting the thrust bearing
1. Loosen bolt A.
2. 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).
3. Tighten bolt A.
Adjusting the guide bearings
1. Loosen bolt B.
2. Set guide bearing against the band saw blade.
3. Turn the band saw wheel by hand in a clockwise direction several times to bring
the guide bearings in correct position. Loosen bolt A, and adjust thrust bearing to
a position of 0.5 mm from rear of blade. Both guide bearings should JUST
TOUCH the band saw blade.
4. Tighten bolt B again.
5. Close lower blade guard.
6. Close the lower cover door.
Aligning the saw table at right angles to the band saw blade
1. Raise upper blade guide fully (see “Operation”).
2. Check band saw blade tension (see “FUNCTIONAL DESCRIPTION”).
Turn the handle clockwise to tilt the table in an anticlockwise direction, and turn
the handle anticlockwise to tilt the table in a clockwise direction.
3. Loosen lock lever.
4. Using a try square, set the table at right angles to the blade by turning the handle
to adjust the table, and tighten the lock lever again.
5. Adjust limit stop screw until it touches the saw housing.
