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.
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 the Air Grease Gun and the grease, in a location that is 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

7. Use eye and ear protection. Always wear ANSI approved impact safety goggles. Wear
an ANSI approved dust mask or respirator when working around chemical dusts and
mists.
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 and turn off the compressor when not in
use.
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. Do not carry any tool with your finger on the trigger,
whether it is connected to the air compressor 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 any switch 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. This product is to be repaired and serviced only
by a qualified 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.
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 Grease Gun.
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 air 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. 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 qualified technician.
20. Compressed air only. Never use combustible gas as a power source.

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. If desired, for quick tool connection, you will need to prepare a 1/4” quick air connector
(not included) to connect to the air source hose. First, wrap the 1/4” quick air connec-
tor (not included) with pipe thread seal tape (not included) before threading it onto the
3/8” air source hose. Then, connect the 1/4” quick air connector to the Air Inlet (2) on
the Grease Gun.
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. To check your air system, set the air pressure on your compressor to 90 PSI. Do not
exceed the testing air pressure of 90 PSI.
3. Check the air connection for leaks. After test is complete, disconnect from the air supply
until grease is loaded into the Air Grease Gun.
Unpacking
When unpacking, check to make sure the parts listed on page 9 are included. If any
parts are missing or broken, please call Harbor Freight Tools at the number on the cover of
this manual as soon as possible.
21. Check hoses carefully. Never use the Grease Gun if the hoses are cracked, frayed, or
kinked. Avoid problems by not severely bending the hoses. If hoses appear damaged,
have them replaced.
22. This Grease Gun is designed only to hold and dispense grease. Never use it to hold
and dispense any other material.
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
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.

Operating the Grease Gun
Note: If your application requires the Flexible Hose (9b), attach it to the Rigid
Coupler (9).
Note: If your Grease Gun fails to work, it is usually because air pockets have formed
in the Gun. To remove them, disconnect the Grease gun from the air supply. Pull back
and fully extend the Handle (21). Now push the Handle forward into the Grease Tube
while depressing the Air Vent Valve (11). Reconnect the air supply to the Grease gun
and then squeeze and release the Trigger (3) several times until the trapped air is ex-
pelled. Repeat as needed.
See FIGURE C on page 5.
Before every use, prime the Grease Gun by operating the Gun (see below) until
grease flows from the tip. If it does not prime properly, follow the directions
above for venting trapped air.
1. Attach the Grease Gun to the air source hose following the directions on page four.
Set the air compressor to 30 - 100 PSI.
2. Squeeze the Trigger (3) to inject a small amount of grease. Release and squeeze the
trigger repeatedly to inject more grease.
3. Disconnect from the air source hose before refilling the Grease Gun. Turn off the air
compressor.
Warning!! The Grease Gun may still have air pressure after disconnected from the
air source. Point the Grease Gun into a suitable receptacle and fire it until all of the
air is expended.

Troubleshooting
If the Grease Gun does not operate:
1. Check that gun is properly connected to the air source and the air compressor is set
to 30 - 100 PSI.
2. If it still doesn’t operate, take it to an qualified service technician to check the Springs
(6 and 17), and the Piston Assembly (5).
If the Grease Gun cycles and does not pump grease:
1. Repeat priming operation on page 7.
2. Check to see if you are out of grease.
3. Disconnect any extensions and prime until grease flows.
If the Grease Gun continues to lose prime:
1. Release trapped air.
2. Refill the Grease Gun and repeat priming.
3. Have an qualified service technician check the position on the Follower Assembly.
If the Grease Gun still doesn’t operate, contact a qualified service technician.
Maintenance
Always disconnect from the air source hose before attempting any maintenance.
