INCREASE BLADE TENSION
2. Loosen the hex head screw BEFORE adjusting
the setscrew.
3. Turn the setscrew simultaneously with the
adjustment knob making the blade track
properly against the shoulder of the pulley.
4. After adjusting the setscrew, tighten the hex
head screw.
DECREASE BLADE TENSION
5. Set the adjustable blade seat according to
material size. The arrow on the front side of
the band saw indicates the direction of blade
movement.
6. Adjust the guide assembly so the blade just
barely touches the back-up bearing.
CHANGING BLADE SPEED
Turn the metal cutting band saw power
switch to the OFF position. Disconnect the
band saw from the AC power source before
make any adjustments or changing blade
speed.
Whenever using the metal cutting band
saw, the blade speed should be changed to
match the material that is being cut. Refer
to Table 1 , Metal Cutting Speeds.
1. Open the pulley guard cover. See Figure 11.
2. Loosen the adjustment screw on the
motor mounting plate.
3. Pivot the mounting plate towards the front of the band saw until the drive belt
can be easily removed from the pulley.
4. Using the “Speeds in FPM” table, adjust the belt for the speed needed to cut the
material desired.

To set the blade tension, proceed with the following
steps. See Figure 8.
1. Press the blade lightly with the left hand.
2. Make sure the rear portion of the blade is against
the flange of the blade wheel.
3. Test the blade tension. The blade should press
inward approximately 0.04" (1mm).
4. While pressing on the blade with the left hand,
turn the blade tension adjustment knob until the
proper blade tension is achieved.
ADJUSTING BLADE TRACKING
The blade tracking has been set and tested at the factory. The adjustment of the
blade tracking is relatively rare if the band saw is used correctly and properly main-
tained.
Should the blade tracking go out of adjustment, the
blade will leave the wheel and cause severe damage to
the band saw. If the blade breaks, damage to band saw
and possible several injuries to the operator could occur.
The following steps should be used to adjust the blade
tracking. See Figure 9 and 10.
1. Turn adjustment knob on front end of band saw simul-
taneously adjusting the setscrew making the blade
track properly against the shoulder of the pulley.
