CHANGING SPEED SETTINGS
This model 90-170B has 2 different speed settings; low and high.
-
Low speed is to be used for cutting soft woods over 4"
in height or hard woods over 2" in height.
-
High speed is best for cutting soft woods under 4" in
height or hard woods under 2" in height.
Note: If wood starts to burn at high speed, stop and change to the
lower speed setting.
At the back of the bandsaw, just next to the motor, there is a
ratchet lever
A
for loosening the tension on the drive belt. When
you pull it out as shown in
B
, it disengages for resetting. When you
release it, it engages the bolt for screwing or unscrewing
C
.
1.
Unscrew the bolt a few turns counterclockwise then lift the
motor by hand
D
and tighten ratchet lever
A
to lock the
motor in position. This will loosen the drive belt enough to
move it between one set of pulleys and the other.
2.
Open the lower wheel cover door.
3.
To set the bandsaw speed to the slower setting; 2300 Lin.
FPM (690 MPM), place the belt on the frontmost set of pul-
leys as in
E
.
4.
To set the bandsaw speed to the faster setting; 3250 Lin.
FPM (975 MPM), place the belt on the rearmost set of pul-
leys as in
F
.
5.
Having repositioned the belt, set the motor back to it’s initial
position to tighten the belt around the pulleys, then turn the
ratchet lever clockwise until it is tight and the motor does
not move.

ADJUSTING THE BLADE GUARD FOR DEPTH OF CUT
The blade guard can be moved up or down to accommo-
date the height of the work to be cut
A
. To prevent the bla-
de (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
B
to prevent the blade from flexing out of position or off-
line during cutting.
Adjust the height of the blade guard to suit the thickness 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 lock knob
C
.
3.
Move the blade guide assembly up or down by turning
the handwheel
D
. Then re-tighten the lock knob
C
.
Note: The depth gauge
E
on the blade guard can be used as a
reference but it is not intended for high precision measurements.
