Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lit. Do not use electrically powered
tools in the presence of flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, extension cords, or air hoses.
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to
do the work of a larger industrial tool. There are certain applications for which this
tool was designed. It will do the job better and more safely at the rate for which it was
intended. Do not modify this tool and do not use this tool for a purpose for which it was
not intended.
6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.
7. Use eye and ear protection. Always wear ANSI approved impact safety goggles. Wear
a full face shield if you are producing metal filings or wood chips.Wear an ANSI approved
dust mask or respirator when working around metal, wood, and chemical dusts and
mists. REV 08c, 09f

8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines or air hoses.
9. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air hoses
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.
10. Disconnect air supply. Disconnect air hose when not in use or when changing
blades.
11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are
removed from the tool or machine work surface before plugging it in.
12. Avoid unintentional starting. Be sure the Throttle Lever (13) is in the Off position and
the safety engaged when not in use and before plugging in. Do not carry any tool with
your finger on the Throttle Lever (13), whether it is plugged in or not.
13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when
you are tired.
14. 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 the Throttle Lever does not turn On and Off properly.
15. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
16. 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.
17. Do not operate tool if under the influence of alcohol or drugs. Read warning labels
if taking prescription medicine to determine if your judgement or reflexes are impaired
while taking drugs. If there is any doubt, do not operate the tool.
18. 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 compressor without heating
up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage
to the tool. Check your air compressor’s manual for the appropriate size cord.
19. Maintenance. For your safety, maintenance should be performed regularly by a qualified
technician.
20. Compressed air only. Never use combustible gas as a power source.
21. Never use this Air Body Saw without the Blade Guard being in place.
Note: Performance of the compressor (if powered by line voltage) may vary depending
on variations in local line voltage. Extension cord usage may also affect tool perfor-
mance.

Warning:The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be under-
stood 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
For best service you should incorporate an oiler, regulator, and inline filter,
as shown in the diagram above. Hoses, couplers, oilers, regulators, and filters
are all available at Harbor Freight Tools.
1. You will need to prepare a 1/4” - 18 air connector (sold separately) to connect to the air
inlet on the Saw. First, wrap the 1/4” air connector (not included) with pipe thread seal
tape before threading it into the Air Inlet (9). Connect the 3/8” ID Air Source Hose to the
Saw.
Note: If you are not using an automatic oiler system, before operation, add a few drops of
Pneumatic Tool Oil to the airline connection. Add a few drops more after each hour of
continual use.
2. Set the air pressure on your compressor to 90 PSI. Do not exceed the maximum air
pressure of 90 PSI.
3. Check the air connection for leaks. Disconnect the tool from the air source.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities, contain 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 and cement or 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
equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Adding or Changing Blades
Warning! Always disconnect the Saw from the air source before adding or changing
blades. After disconnecting the Saw from the air compressor, there could still
be enough air pressure to activate the Saw. Always position the Saw safely
and activate the Throttle Lever (13) repeatedly to make sure all of the air is
expended.
Refer to FIGURES 2 and 3below, and the Assembly Drawing on page 8.
1. The Blade Guard (34) may be removed when replacing blades, but it must always be on
during operation. Using the Saw without the Blade Guard (34) can result in severe
injury. To remove the Blade Guard (34), loosen and remove the two Set Screws (24).
When replacing the Blade Guard (34), place it in the slots and tighten the Set Screws
(24).
2. To change blades, first remove the Chuck Cover (26) by removing the Screw (38). Swing
the Chuck Cover (26) back on its hinge.
3. Loosen the two Set Screws (30) inside, until the blade can be removed. Replace with a
new blade and tighten the Set Screws (30). Replace the Chuck Cover (26) and carefully
tighten the Screw (38). Do not overtighten the Screw (38) or you may break the plastic
Chuck Cover (26).
Note: Never use a dull, bent, or cracked blade.
Check that the blade and blade guard are tight before each use.
