This manual provides critical safety instructions on the proper setup,
operation, maintenance, and service of this machine/tool. Save this
document, refer to it often, and use it to instruct other operators.
Failure to read, understand and follow the instructions in this manual
may result in fire or serious personal injury—including amputation,
electrocution, or death.
The owner of this machine/tool is solely responsible for its safe use.
This responsibility includes but is not limited to proper installation in
a safe environment, personnel training and usage authorization,
proper inspection and maintenance, manual availability and compre-
hension, application of safety devices, cutting/sanding/grinding tool
integrity, and the usage of personal protective equipment.
The manufacturer will not be held liable for injury or property damage
from negligence, improper training, machine modifications or misuse.
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.

M. Blade Guide Arm: Holds blade guide that
supports bandsaw blade. Arm is placed as
close to workpiece as possible during cutting
to prevent blade from twisting.
N. Blade Guide Scale: Displays position of
blade guide arm relative to workpiece.
O. Blade Speed Adjustment Knob: Controls
bandsaw blade speed. Rotate knob clockwise
to decrease blade speed or counterclockwise
to increase blade speed. IMPORTANT: To
avoid damaging machine, ONLY change
blade speeds while the motor is running.
P. Work Stop: Can be positioned on either
side of vise base to support repetitive cutting
operations. The stop is placed on same side
of machine where cut is made.
Q. Auto-Stop Adjustment Lever: Sets maxi-
mum headstock height. Adjust by changing
position of lower limit switch. This feature
is useful for speeding up repetitive cuts by
eliminating unnecessary headstock travel.
R. Blade Tension Handwheel: Increases or
decreases blade tension.

S. Movable Vise Jaw: Features quick release
that allows jaw width to be adjusted when
changing from one workpiece size to another.
T. Vise Handwheel: Rotate to manually position
movable vise jaw close to workpiece.
