SAFETY WARNING & CAUTIONS
WARNING: When using pneumatic equipment, basic safety precautions should always be fol-
lowed to reduce the risk of personal injury and hazards due to over pressurization. READ ALL
INSTRUCTIONS BEFORE USING THIS TOOL!
1. KEEP WORK AREA CLEAN. Cluttered areas invite injuries.
2. OBSERVE WORK AREA CONDITIONS. Do not use tools in damp, wet, or poorly
lit locations. Don’t expose to rain. Keep work area well lit. Do not use electrically
powered air compressors in the presence of ammable gases or liquids.
3. KEEP CHILDREN AWAY. Children must never be allowed in the work area. Do not
let them handle machines, tools, or hoses.
4. STORE IDLE EQUIPMENT. When not in use, tools must be locked up 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. Do not use a 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. Nonskid footwear is recommended. Wear restrictive hair covering
to contain long hair.
7. USE EYE AND EAR PROTECTION. Always wear ANSI approved impact safety
goggles when working. Wear an ANSI approved dust mask or respirator when
working around metal, wood, and chemical dusts and mists.
8. DO NOT ABUSE THE COMPRESSOR’S CORD. Do not yank compressor’s cord
to disconnect it from the receptacle. Do not carry tools by the cord.
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 clean for better and safer perfor-
mance. Follow instructions for lubricating and changing accessories. Inspect hoses

SKU 98898 For technical questions, please call 1-800-444-3353. Page 3
for leaks prior to use. The handle must be kept clean, dry, and free from oil and
grease at all times.
11. AVOID UNINTENTIONAL STARTING. Do not carry any tool with your nger on the
trigger, whether it is connected to the compressor or not.
12. STAY ALERT. Watch what you are doing, use common sense. Do not operate any
tool when you are tired.
13. CHECK DAMAGED PARTS. Before using any tool, any part that appears dam-
aged 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 operation. Any part that is damaged should be properly repaired or replaced
by a qualied technician. Do not use the tool if any switch does not turn on and off
properly.
14. REPLACEMENT PARTS AND ACCESSORIES. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accesso-
ries intended for use with this tool. Approved accessories are available from Harbor
Freight Tools.
15. DO NOT OPERATE TOOL IF UNDER THE INFLUENCE OF ALCOHOL OR
DRUGS. Read warning labels on prescriptions to determine if your judgment or
reexes are impaired while taking drugs. If there is any doubt, do not operate the
tool.
16. DRAIN COMPRESSOR EVERY DAY. Do not allow moisture to build up inside the
compressor.
17. MAKE SURE ALL EQUIPMENT IS RATED TO THE APPROPRIATE CAPACITY.
Make sure that regulator is set at least 10 PSI lower than the lowest rated piece of
equipment you are using.
18. DO NOT POINT AT PEOPLE OR ANIMALS. Whether the Riveter is loaded or not,
do not point at anything but what you plan on riveting.
19. BE CAREFUL WHEN LOADING RIVETER. Do not point at yourself. Never hold
the Trigger when loading.
20. NEVER OPERATE WITHOUT THE SAFETY CAP IN PLACE.
21. COMPRESSED AIR ONLY. Never use combustible gas as a power source.
22. WARNING: The brass components of this product contain lead, a chemical known
to the State of California to cause birth defects (or other reproductive harm). (Cali-
fornia Health & Safety code § 25249.5, et seq.)

UNPACKING
When unpacking, check to make sure the following parts are included. All sizes
listed below are approximate. If any parts are missing or broken, please call Harbor
Freight Tools at: 1-800-444-3353. There should be one Air Hydraulic Riveter, two combi-
nation wrenches, an extra set of jaws, and a three Nose Pieces threaded into the base
of the riveter. A fourth Nose Piece comes installed in the Riveter.
SET UP
It is advisable to use an in-line oiler. If you are not using an in-line oiler, put a few
drops of pneumatic oil into the Air Inlet (35) prior to every operation.
To Install A Nosepiece:
1.
NOSEPIECE (1)
OUTER CYLINDER (2)
TRIGGER (25)
FIGURE B
RIVET
(not included)
The Riveter comes with a set of four Nosepieces (1). The sizes of the Nosepieces
are 1/4”, 1/8”, 5/32”, and 3/16” and must be matched with the size of the rivet pin
(1/4”, 1/8”, 5/32”, or 3/16”) you intend to use. (See Figure B.)
2. Use the accessory Spanner when changing Nosepieces (1). Also, use care when
unscrewing a Nosepiece as the spring action in the Outer Cylinder (2) will cause
the Nosepiece to “pop out”. (See Figure B.)
Note: Nosepieces are stored underneath the Base Cover (34).

OPERATION
1. Depending on the size of rivet pin used, attach the corresponding Nosepiece size
(1/4”, 1/8”, 5/32”, or 3/16”) with the accessory Spanner Wrench (36).
2. IMPORTANT: When drilling rivet holes in a workpiece, make sure to use the same
diameter drill bit as the outer diameter of rivet sleeve you will be using.
3. Turn on the air compressor, and set its regulator between 90-120 PSI.
Do not exceed 120 PSI.
4. Insert the pin (long, thin end) of a rivet fully into the Nosepiece (1). Insert the
sleeve (short, thick end) of the rivet through the pre-drilled hole in the workpiece.
Do not touch the Trigger (25) when you are inserting rivets.
5. Hold the Riveter rmly with both hands, and squeeze the Trigger (25) to activate
the Riveter. Repeat as necessary. Then, release pressure on the Trigger. See
Figure B.
6. When nished using the Riveter, turn off the air compressor. Squeeze the Trigger
(25) again to release any compressed air in the Riveter. Then, disconnect the air
hose from the tool.

INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Always wear ANSI-approved safety impact goggles when per-
forming any inspection, maintenance, or cleaning procedures.
WARNING! Prior to performing any inspection, maintenance, or cleaning of the Riveter,
make sure to disconnect the air hose from the tool. Then, squeeze the Trigger (25)
again to release any compressed air in the Riveter.
1. To clean the exterior of the Riveter, wipe with a clean, damp cloth using a mild
detergent or mild solvent. Do not immerse the tool in liquids.
2. To clean and change the Jaws:
a. Unscrew and remove the Outer Cylinder (2), using the accessory Spanner.
b. Use the Spanner to unscrew and remove the Jaw Cylinder (7). Use care as there
is a Jaw Pusher Spring (6) behind the Jaw Cylinder (7) which may y out.
c. Remove the Jaws (4) from between the Jaw Cylinder (7).
d. If you are going to clean the Jaws (4), use a steel brush and mild solvent. Apply a
light coat of machine oil to the Jaws (4).

FIGURE C
OUTER
CYLINDER
(2)
If you are going to replace the Jaws: Insert the new Jaws (4) into the Jaw Cylinder
(7). (See Figure C.)
f. When re-assembling the Jaw Cylinder (7), make sure the Jaw Pusher’s (5) head
lines up with the Jaws. (See Figure C.)
g. Check the distance from the head of the Jaw Cylinder (7) to the mounting threads
of the Outer Cylinder (2) using the gauge on the 3-Way Spanner Wrench. With
the gauge at a slight incline, the back of the gauge should rest on the beginning
of the Frame Head threads, while the front of the gauge should rest on the front
edge of the Jaw Carrier (3). If it does not, have a qualied service technician re-
pair the Riveter. (See Figure C.)

To Prime The Riveter:
Note: If the riveter’s performance declines, it may be due to insufcient hydraulic oil.
Rell the hydraulic oil using the procedure below.

bottom of the Riveter. See Figure D.
2. Use a pair of pliers (not included) to remove the Piston Head (22) from the Air
Cylinder (19). See Figure D.
3. Hold the Air Cylinder (19) upside down, and pour in hydraulic oil (not included).
The ll level should only reach the top of the Frame.
4. Insert the Piston Assembly back into the Air Cylinder (19). See Figure D.
5. Use the Spanner to rmly screw the Air Cylinder Lid (24) back onto the Air Cylinder
(19). See Figure D.
