Lower blade guide adjustment
WARNING. Always ensure that the saw is switched
off and unplugged from the power supply before making
any adjustments.
1. The lower blade guide adjustments consist of a thrust
bearing that supports the band saw blade from the rear
and two guide pins that provide lateral support, these
need to be readjusted after every band saw blade
change or tracking adjustment.
2. The work table needs to be tilted 45° and the door needs
to be open before the thrust bearing locking screw and
guide pins can be adjusted. This helps give better access
to the adjustment screws.

loosen the thrust bearing
locking screw using the 3mm
hex key supplied. It is easier
to access the thrust bearing
screw if the work table is
placed on a 45° angle.
2. Adjust the thrust bearing
position until it is 0.5mm away
from the band saw blade.
When the band saw blade
is turned by hand it should
not make contact with the
thrust bearing.
3. Tighten the thrust bearing
locking screw.
