7. 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.
8. Use eye and ear protection. Always wear ANSI approved impact safety
goggles.
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. 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. 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.
16. Guard against electric shock. Prevent body contact with grounded
surfaces such as pipes, radiators, ranges, and refrigerator enclosures.
17. 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.
18. 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.
19. Use proper size and type extension cord. If an extension cord is required

SKU 46365 Page 4
for the Air Compressor, 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. 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, service and maintenance should be
performed regularly by a qualified technician.
Note: Performance of this tool (if powered by line voltage) may vary depending on
variations in local line voltage. Extension cord usage may also affect tool perfor-
mance.
Special Warnings for this Tool
It is especially important that you read and comply with the following safety
precautions.
1. Never, under any circumstances, press the tip of this tool against another
person or yourself.
2. Excess air may remain in the tool even after the tool is disconnected from
the air supply. For this reason, be especially careful never to carry this tool
with your finger on the trigger, and do not press the tip against any surface
even when the tool is not connected to an air supply.
3. While using this tool, be sure to keep fingers, hands and all other body parts
away from the tip of the tool.
4. Never use combustible gas as a power source.
5. Never use gasoline or other flammable liquids to clean the Stapler.
6. Do not exceed the maximum operating pressure of 95 PSI as stated in the
Specifications Chart and warning label.
7. Ear protection is required for the operator and others in the work area.
8. Never attempt to drive staples on top of other staples.
9. Never attempt to keep the Trigger depressed with tape or wire.
10. Never leave the tool unattended or connected to the air supply when not in
use.
11. Do not throw the tool or use it as a hammer to knock material into place.
12. Avoid prolonged use of the Stapler, and do not use this tool if you have back,
neck or other bodily injuries that might be aggravated by the jerking motion
of the tool. Stop using this tool if you experience pain in your arms or hands.

SKU 46365 Page 5
13. Do not use this tool if it is not loaded, as this will accelerate wear on the tool.
14. Be sure all hoses and fittings are free from damage and dirt. Replace any
part that does not appear to be operating properly.
Warning: People with pacemakers should consult with their physician(s)
before using this product; operation of equipment in close proximity to a heart
pacemaker could cause interference or failure of the pacemaker.
Warning: The warnings, cautions, and instructions discussed in this instruc-
tion manual cannot cover all possible conditions and situations that may oc-
cur. 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.
Unpacking
When unpacking, check to make sure all parts listed on Page 7 are included.
If any parts are missing or broken, please call Harbor Freight Tools at the number
on the cover of this manual.
Maintenance
1. Do not store the Stapler in cold or freezing temperatures. If you are
operating the Stapler in cold weather, use a permanent antifreeze as
lubricant. Certain drying agents may damage o-rings and seals, so be sure
to check these periodically.
2. It is recommended that you use an Oiler with this tool, especially if you use
this tool regularly. Be sure the check the oil level in the Oiler before each
use, and during prolonged periods of use.
3. If you are not using an Oiler, you must lubricate the Stapler before and after
each use. Be sure to disconnect the tool from the air supply if you are
lubricating it by hand. To lubricate this tool: add 5-6 drops of air tool
lubrication to the Air Inlet. Do not use detergent oil or oil adhesives. Run the
Stapler for a short time after lubrication and wipe off all excess oil.
4. A filter (not included) can be used to remove liquid and solid impurities which
may rust or block internal parts and mechanisms. Periodically check the
Filter and drain any water.

SKU 46365 Page 6
Air Connection
Note: Air Compressor is not supplied.
You may use Quick-Couplers and Quick-Connectors (not supplied) as shown in the
diagram above. Do not connect Couplers directly to the Air Inlet. Doing so will
increase the overall bulk of the tool and strain the inlet threads.
1. Read and follow all safety precautions as listed on Pages 2-5 of this manual.
2. Acquire a Union Fitting (not supplied) and screw into the Air Plug [32, see
Assembly Diagram on Page 8]. Tighten with a wrench.
3. Attach a Quick-Connector (not supplied) to the Union Fitting if desired. This
allows quick exchange of the Air Hose to other air tools.
4. If staples do not drive down tightly, adjust to a higher pressure setting until
satisfactory. Reduce air pressure if the staples are being driven too deep.
This air tool requires lubrication during operation. For best results, it is recom-
mended to have an Oiler and Water Filter in line with the Air Supply as shown.
This will extend the life of the tool.
Loading the Stapler
When loading, the Stapler must be discon-
nected from the Air Compressor Hose.
1. Only use the proper size and type of staple
with this tool, as specified in the chart on
Page 2.
2. Disconnect tool from the air supply.
3. Depress the Click Lever [34] to release the
spring-loaded Magazine Assembly [51]
from the Upper Magazine [47]. Slide the Magazine Assembly out as far as it
will go. See Figure A, right.
4. Turn the Stapler upside down. Place a full clip of staples inside the Upper
Magazine so the pointed ends of the staples are directed away from the tool.

5. Slide the Magazine Assembly back into place until it clicks.
Operation
1. Grip the Body [18] of the Stapler with both hands and press the Nozzle [19]
against the surface you wish to staple. Be sure to keep your hands, fingers
and other body parts away from the Nozzle.
2. Depress the Trigger [28] to activate the Stapler.
Your 1/2” Crown Air Stapler is easy to load and fun to use. With its comfortable
grip and lightweight body, your Stapler is an ideal tool for working with upholstery,
insulation, picture frames and more.
