Use the right tool for the job.5. 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 pur-
pose for which it was not intended.
Dress properly.6. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid foot-
wear are recommended when working. Wear restrictive hair covering to contain
long hair.
Do not overreach.7. Keep proper footing and balance at all times. Do not reach
over or across running machines or air hoses.
8. Use eye and ear protection. Always wear ANSI approved impact
safety goggles and appropriate hearing protection. Wear a full face
shield if you are producing metal lings or wood chips. Wear an ANSI
approved dust mask or respirator when working around metal, wood,
and chemical dusts and mists. Other people in the work area must also wear ANSI
approved impact safety goggles.
Maintain tools with care.9. 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 handle must be kept clean, dry, and free from oil and grease at all
times. Do not operate a tool if any portion of the tool’s operating controls are inop-
erable, disconnected, altered or not working properly.
Disconnect Air Hose and release any built-up air pressure.10. Never service the
Nailer, clear jams, or disassemble with the air hose attached. Always release any
built-up air even after disconnecting hose. Disconnect the Nailer when not in use.
Remove adjusting keys and wrenches.11. Check that keys and adjusting wrench-
es are removed from the tool or machine work surface before attaching to an air
source.
Avoid unintentional starting.12. Be sure the trigger is in the Off position when not
in use and before plugging in. Do not carry any tool with your nger on the trigger,
whether it is attached to an air source or not. Do not point the tool towards your-
self or anyone whether it contains fasteners or not.
Stay alert.13. Watch what you are doing, use common sense. Do not operate any
tool when you are tired.
Check for damaged parts.14. 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 xtures; and any other condition that may affect proper opera-

Page 4SKU 47612 For technical questions, please call 1-800-444-3353.
tion. Any part that is damaged should be properly repaired or replaced by a quali-
ed technician. Do not use the tool if the trigger does not operate properly.
Guard against electric shock.15. Prevent body contact with grounded surfaces
such as pipes, radiators, ranges, and refrigerator enclosures.
Replacement parts and accessories.16. This product is to be repaired and ser-
viced only by a qualied technician. When this product is serviced, only identical
replacement parts should be used. 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.
Do not operate tool if under the inuence of alcohol or drugs. 17. Read warning
labels if taking prescription medicine to determine if your judgement or reexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.
Use proper size and type extension cord.18. If an extension cord is required, it
must be of the proper size and type to supply the correct current to the compres-
sor without heating up. Otherwise, the extension cord could melt and catch re,
or cause electrical damage to the tool. Check your air compressor’s manual for
the appropriate size cord. It is also possible that the use of an extension cord
may cause your circuit breaker to trip or your panel fuse to break. If this happens,
either use the compressor without an extension cord or nd a larger amperage
circuit to use.
Maintenance.19. The maintenance outlined in the maintenance section should be
performed regularly. For your safety, this product should be serviced or repaired
regularly only by a qualied technician.
Compressed air only.20. Never use combustible gas as a power source.
21. Do not load nails with the trigger or safety depressed.
Unintentional ring may occur. Do not load nails when the air hose is
connected to the tool. Always assume the tool contains fasteners.
Disconnect air supply before loading the Nailer.22. Before reloading (or making
any adjustments to) the Nailer, make sure the compressed air is disconnected.
Fire fasteners into an appropriate work surface only.23. Do not attempt to re
fasteners into surfaces too hard to penetrate. Do not drive fasteners on top of
other fasteners, or at too steep an angle. Fasteners can ricochet causing personal
injury. Never re the Nailer into the air, or point it toward yourself or another per-
son. Always wear ANSI approved safety goggles during use, maintenance, and
reloading.
Do not re fasteners too close to the edge of a workpiece. 24. They may split the
workpiece and y free, causing personal injury.

the tool res, stop immediately and have it repaired by a qualied service techni-
cian.
Depress the nose against the workpiece and squeeze the Trigger (47).8. The tool
must cycle (re) only once. Release the Trigger and squeeze it again. The tool
must not cycle (re). With the Trigger held, carefully lift the nailer and press it
against the workpiece again. The tool must not cycle (re). If it fails to perform
in the manner explained in bold, have it repaired by a qualied service technician.
Loading Nails
ALWAYS WEAR ANSI APPROVED IMPACT SAFETY GOGGLES WHEN
RELOADING OR DOING ANY OTHER MAINTENANCE ON THIS TOOL.
Other people in the work area must also wear ANSI approved impact safety
goggles.
Warning! Make sure the Nailer is not attached to the air hose whenever loading
the tool.
1. Insert the Nails into the opening in the End Plate (81) and into the Magazine (69),
letting the heads of the Nails ride in the Magazine T-Slot until they are past the
Nail Stop (78) (small pin inside Magazine). Bring the Pusher (71) to the rear of
the Magazine, and release it to apply pressure on the Nails.

Operating the Nailer
ALWAYS WEAR ANSI APPROVED IMPACT SAFETY GOGGLES WHEN
RELOADING OR DOING ANY OTHER MAINTENANCE ON THIS TOOL.
Other people in the work area must also wear ANSI approved impact safety
goggles.
Attach the Nailer to the air supply at the Air Inlet (57). Start your compressor and1. check the pressure making sure it is set at the recommended 70-120 PSI.
Rotate the Deector (6) so that the exhaust air blast will be directed away from the 2. operator.
To re, place the Nose Cushion (89) of the Nailer on the workpiece. With the 3. Trigger (47), Nails can only be driven one way. First, depress the Nose Cushion
against the workpiece. Then, pull the Trigger. The Nailer should not re if the
Nose Cushion is not depressed. This feature is helpful when precise fastener
placement is required. Also, it may reduce the possibility of injury to you or to oth-
ers working with you.
Do not press the Nose Cushion (89) against the work surface with extra force. Al-4. low the tool to do the work. Always allow the tool to recoil off the work surface.
When nished using the Nailer, always disconnect the tool from its compressed 5.
air supply. Empty the Magazine (69) completely of nails. Attempt to re the Nailer
into a piece of scrap wood to ensure it is disconnected and is incapable of ring
any nails.
Make sure to store the Nailer in its accessory Carrying Case and in a clean, dry,6. safe location out of reach of children.

Clearing Jams
ALWAYS WEAR ANSI APPROVED IMPACT SAFETY GOGGLES WHEN
CLEARING JAMS OR DOINGANY OTHER MAINTENANCE ON THIS TOOL.
Other people in the work area must also wear ANSI approved impact safety
goggles.
1. Occasionally a Nail may become jammed in the ring mechanism of the Nailer,
making the tool inoperable. To remove a jammed nail, disconnect the Nailer
from its compressed air supply. Attempt to re the Nailer into a piece of scrap
wood to ensure it is disconnected and is incapable of ring any nails.
2. Have an assistant carefully pull and hold the Pusher (71) back. IF THE
PUSHER (71) IS SUDDENLY ALLOWED TO COME FORWARD, FASTENERS
OR DEBRIS MAY FLY OUT OF THE NAILER, POTENTIALLY CAUSING
SERIOUS PERSONAL INJURY.
3. Open the Lock Handle Unit (91), and remove the Driver Guide Cover A (67).
While keeping the Nailer from being pointed at any person or delicate object,
have your assistant slowly slide the pusher forward in a controlled manner.
If the pusher cannot eject all the nails, including the jammed nail(s), then have
the assistant hold the pusher back while you use a pair of needle nose pliers
(not included) to remove the jammed nail(s) (usually from the Driver Guide (59)
area). Then, slowly bring the Pusher forward to empty the magazine, ensuring no
jams remain.
4. Replace the Driver Guide Cover A, close the Lock Handle Unit, and reload the
Magazine (69) with Nails. Then, reconnect the air supply hose to the tool.
5. Press the Nose Cushion (89) against a scrap piece of wood, and test re
the Nailer several times while checking for proper operation. If the Nailer is
properly ring, you may continue using the Nailer. If the tool fails to perform
properly, immediately discontinue use and have it repaired by a qualied service
technician.
6. When nished working, disconnect the air supply. Remove the Nails. Then,
store the Nailer out of reach of children.
Anytime any maintenance or repairs are done (including clearing jams), FIRST:
Disconnect the Nailer from the air hose.1.
Empty the Magazine (69) completely.2.
Attempt to re the Nailer into a piece of scrap wood to ensure that it is discon-3.
nected and is incapable of ring any nails.

Page 10SKU 47612 For technical questions, please call 1-800-444-3353.
Inspection, Maintenance, and Cleaning
1. Inspect the Nailer frequently and lubricate periodically with Pneumatic tool oil,
then wipe dry. Do not use detergent oil or additives as these lubricants will cause
accelerated wear to the internal seals.
2. Inspect the air supply lter, if present, before each use and clean or replace as
necessary. Dirt and water in the air supply lter are major causes of pneumatic
tool wear. Use a lter/oiler for better performance and longer tool life. The lter
must have adequate ow capacity for the specic application.
3. Clean the external parts of the Nailer with a clean cloth and mild detergent or
nonammable solvent. Then, dry.
4. Store the unit in a safe, clean, dry location out of reach of children and other un-
authorized people.
5. All maintenance, service, or repairs not listed in this manual are only to be
attempted by a qualied technician.
