9. do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
10. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect tool
cords periodically and, if damaged, have them repaired by an authorized technician.
The handles must be kept clean, dry, and free from oil and grease at all times.
11. disconnect power. Unplug tool when not in use.
12. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before plugging it in.
13. Avoid unintentional starting. Be sure the switch is in the Off position when not
in use and before plugging in. Do not carry any tool with your finger on the trigger,
whether it is plugged in or not.
14. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When cutting these materials extra care should
be taken to avoid inhalation and minimize skin contact.
16. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified technician.
Do not use the tool if any switch does not turn On and Off properly.
17. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
18. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
19. do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
20. Use proper size and type extension cord. If an extension cord is required, it must be
of the proper size and type to supply the correct current to the tool without heating up.
Otherwise, the extension cord could melt and catch fire, or cause electrical damage
to the tool. This tool requires use of an extension cord of 0 to 10 amps capability (up
to 50 feet), with wire size rated at 18 AWG. Longer extension cords require larger size
wire. If you are using the tool outdoors, use an extension cord rated for outdoor use
(signified by “WA” on the jacket).
21. Maintenance. For your safety, maintenance should be performed regularly by a
qualified technician.

22. never leave the Bandsaw unattended while it is running. Do not put the Bandsaw
down until the blade comes to a complete stop.
23. Cutting Material. Make sure cutting material is securely fastened down before
operating the Bandsaw. Work slowly and carefully when cutting corners, sharp edges,
ragged welds, etc., to avoid snagging.
Caution: Cutting material and the motor housing can get very hot during operation.
Stop work until unit cools down to safe temperature.
Spray on a coolant or water onto the blade.
note:Performance of this tool (if powered by line voltage) may vary depending on varia-
tions in local line voltage. Extension cord usage may also affect tool performance.
Warning:The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur.It must be understood
by the operator that common sense and caution are factors which cannot be built into
this product, but must be supplied by the operator.

Operation
Warning: Never use a blade which is not in accordance with the sizes approved for
this Bandsaw. If you are unsure of the blade, do not use it and contact a Harbor Freight
technician at the number on the cover of this manual.
Select the proper blade according to the cutting material and the diameter of the workpiece.
This bandsaw comes with a 14 teeth-per-inch blade which is suitable for most applications
(see below).
14 TPI - Soft/ Thick Material( aluminum, lead, rubber-like material, wood )
Other applications for 24 teeth-per-inch blades (not included) are shown below:
24 TPI - Hard/Thin Material ( cast iron, soft steel, hard steel )
Switch Operation
Warning: Before plugging in the Bandsaw make sure the trigger switch on the inside upper
portion of the U-shaped handle returns to it’s original position after being depressed. Test it
by depressing it with your index finger and letting go. It should spring back into position if it
is in working order.
1. When the trigger is pulled, the saw motor will switch on.
2. When the trigger is released, the motor stops.
3. Adjacent to the trigger is the lock button. This enables you to lock on the motor without
continually depressing the trigger. To activate the lock switch, turn on the motor as ex-
plained in Step 1. While continuing to depress the trigger, engage the lock button with
your other hand. Release the trigger and the motor will stay locked on. To disengage the
lock button, pull the trigger again.

How to Cut
1. Secure your work piece to a workbench or other solid surface.
2. Make sure the cord is out of the way.
3. Set the Guide Bar (63) against the work piece.
4. Turn on the Bandsaw and allow it to come up to full speed before starting the cut.
5. Tilt the unit so that the blade is vertical as shown in Figure B. Cut objects from the flattest
side, where the most teeth of the bandsaw will contact the workpiece at the beginning of
the cut.
T
Work-
piece
Figure A
6. When the motor turns on, the blade will begin turning in a counterclockwise direction and
begin cutting.
Figure B
7. Do not apply force to the tool by exerting too much hand pressure or leaning into it. The
weight of the tool itself creates enough force to make a clean cut. Be patient. Forcing or
leaning on the tool may twist or break the blade, damaging the saw and possibly causing
injury.
8. As you reach the end of your workpiece, finish off the cut by slightly raising the unit slowly,
bringing the blade up.
