Adjust Blade Guide Support:
Adjust the position of the blade guide assembly. Loosen the
bottom screw on the right side of the blade guide assembly
using the 4 mm hex key.
Slide the upper blade guide support on the shaft until the
front edge of the blade guides are about

Repeat this procedure for the lower blade guide support.
Replace the blade guard if no additional adjustments are
to be made.

The lower blade guide support screw (37) is the top screw
located on the right of the saw housing under the table (Fig. 11).
Never operate saw without blade guard secured in place.
To do so could result in possible serious personal injury.
To Adjust Blade Guides:
The blade guides help keep the blade from twisting and
binding. The blade will be ruined if the blade teeth hit the
blade guides while using the band saw. The set of teeth and
the sharpened edge of teeth will be damaged by hitting the
blade guides. Proper adjustment of the upper and lower blade
guides will prevent this from happening.
Turn the lock knob counterclockwise to unlock the blade
guide assembly. Turning the blade guide knob clockwise,

Tighten all screws securely.
Replace the blade guard once the saw table has been
squared.
ADJUSTING THRUST BEARINGS, BLADE GUIDE
SUPPORT, AND BLADE GUIDES (Fig. 10, 11, 12)

and lower thrust bearings be adjusted equally.
Adjust the thrust bearings first. Using the 4 mm hex key,
loosen the thrust bearing screw.
