PREPARATION & ADJUSTMENTS
CONTROLLING THE HYDRAULIC SYSTEM
The hydraulic system is used to control the blade’s feed
rate and to lock the saw arm in the raised position. The
hydraulic lever (Fig. 8 - 1) controls whether the cylinder
is ON or OFF. The adjustment knob (Fig. 8 - 2) con-
trols the how fast the saw arm comes down.
1. To turn OFF the flow of hydraulic fluid, turn the
hydraulic lever (Fig. 8 - 1) clockwise (pointing upwards,
perpendicular to the cylinder axis). This will lock the
saw arm in the raised position.
2. To turn ON the flow of hydraulic fluid, turn the hy-
draulic lever (Fig. 8 - 1) counterclockwise. This will al-
low the saw arm to come down from the raised position.
3. To DECREASE the feed rate, turn the adjustment
knob (Fig. 8 - 2) clockwise (towards SLOW).
To INCREASE the feed rate, turn the adjustment knob
(Fig. 8 - 2) counterclockwise (towards FAST).
WARNING:
To prevent injury from accidental operation, switch OFF and unplug the tool before making
any adjustments.

CHANGING THE BLADE SPEED
The band saw is capable of running the blade at 135,
160, 240 and 390 FPM. Adjust the blade speed by
changing the v-belt placement.
1. Loosen the motor lock screw on the rightmost side
of the machine (Fig. 9 - 1). Loosen the motor slide
screw (Fig. 9 - 2) underneath the motor plate enough to
permit the motor to slide.
2. Slide the motor plate (Fig. 9 - 3) to reduce belt ten-
sion and enable belt changing. You may need to tap the
plate with a rubber mallet.
3. Remove the Phillips head screw (Fig. 10 - 1) and
washer to open the belt cover, located above the motor.
4. Referring to the speed label (Fig. 11), position the
belt into the desired pulley combination for your se-
lected speed. Close the cover and reinstall the washer
and screw.
5. Slide the motor plate back into position. Then tight-
en the slide screw and lock screw.
