CHANGING SPEED SETTINGS
This model 90-140 14" wood cutting bandsaw 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.
To change the speed setting:
1.
Turn off power and disconnect the bandsaw from the po-
wer source to avoid unintentional start-up of the bandsaw.
2.
Open the lower wheel cover door.
3.
At the back of the bandsaw, just above the motor, there is
a ratchet lever
A
for loosening the tension on the drive
belt. When you pull it out, as in
A
, it disengages for resetting.
When you release it as in
B
, it engages the bolt for screwing
or unscrewing. (You can tell when it is engaged by the
orange indicater button

showing).
To loosen the drive belt, unscrew the bolt a few turns counter-
clockwise then pull up on the capacitor cover of the motor
C
pivot the motor to the left. This loosens the belt enough to move
it between one set of pulleys and the other.
4.
To set the bandsaw speed to the slower setting; 1630 FPM
(495MPM), place the belt on the frontmost set of pulleys
as in
D
.
5.
To set the bandsaw speed to the faster setting; 2730 FPM
(832MPM), place the belt on the rearmost set of pulleys
as in
E
.
6.
Having repositioned the belt, push down firmly on the mo-
tor capacitor cover to tighten the belt, then turn the ratch-
et lever clockwise until it is tight and the motor does not
move.

OPERATING INSTRUCTIONS
NOTE: Now that you have completed the four adjustment steps which are an essential part of safe, accurate bandsaw
operation, it would be a good idea to make yourself a checklist as follows to ensure that each adjustment to the bandsaw
is made in the proper order starting with the general safety precaution:
1.
Turn off the bandsaw and unplug the power cord.
2.
Adjust blade tension.
3.
Adjust blade tracking.
4.
Adjust upper blade guides and thrust bearing.
5.
Adjust lower blade guides and thrust bearing.
CHECKLIST BEFORE STARTING
These additional safety measures should be be included in your checklist:
6.
Make sure all the blade guards are in place.
7.
Make sure the bandsaw table and work area in general are clean and free of sawdust and debris.
These steps should always be followed when any adjustment is performed, the blade is changed, or periodically as vibra-
tion and normal wear and tear on the machine could throw these parts out of alignment.
