ADJUSTING THE UPPER GUIDES AND THRUST BEARING
Note: Before adjusting the upper and lower blade guides and thrust bearings, make sure the blade is tensioned and track-
ing properly. Adjust the upper and lower blade guides and thrust bearings after each blade tension and tracking adjust-
ment. Whenever the upper blade guide and thrust bearing are adjusted, the lower blade guide and thrust bearing should
also be adjusted.
The blade guides keep the blade from moving from side to side during cutting and must be snug but not touching
the blade in order to ensure accurate cuts. The space between each bearing and the blade must not exceed 0.02"
(the thickness of a sheet of paper). If less space is left, the blade will get stuck or jammed between both bearings. Too
much friction will cause blade to overheat and break. Also, the guides must remain at least 1/32” behind the blade
teeth to prevent damage to the blade.
The thrust bearing keeps the blade from moving back and out of position when the work is being fed into the blade
and must be very close to the back of the blade to prevent damage to the blade during cutting.
ADJUSTING THE BLADE GUARD FOR DEPTH OF CUT
1/8” - 1/4”
The blade guard can be moved up or down to accommodate the height of the work to be cut. To prevent the
blade (which is flexible and which would not otherwise be supported) from slipping out of position during cutting,
and to reduce risks of injuries, a minimum amount of blade should be exposed.
The blade guard should be set 1/8” - 1/4” above the work-
piece to prevent the blade from flexing out of position or
off-line during cutting.
Adjust the height of the blade guard to suit the thick-
ness of the workpiece as follows:
1. Make sure the bandsaw is turned off and the power
cord is disconnected from the power source.
2. Loosen the smaller lock knob .
3. Move the blade guide assembly up or down by turn-
ing the adjustment knob
. Then re-tighten the lock
knob .
Note: The depth gauge on the front of the blade guard
can be used as a reference but it is not intended for high
precision measurements.
workpiece
Adjust the positioning of the upper blade guides as follows:
1. Loosen the two Allen bolts with the 5 mm Allen key
provided and slide the two blade guides along the
elongated hole in the mounting bracket
, toward
the blade.
To avoid injury, make sure that the switch is in
the “OFF” position and that the power cord is
unplugged before performing any adjustments
on the bandsaw.
