Inspect Compressor, engine, pump and equipment looking for damaged, loose, and missing parts
before set up and starting. If any problems are found, do not use equipment until fixed properly.
>&$*- At the beginning of the day’s first use of the Air Compressor, check for air leaks by applying soapy water to
connections while the Air Compressor is pumping and after pressure cut-out. Look for air bubbles. If air bubbles
are present at connections, tighten connections. Do not use the air compressor unless all connections are air tight.
The extra air leaking out will cause the compressor to operate too often, increasing wear on the compressor.

Premium quality 30-weight, non-detergent air
compressor oil (sold separately) is recommended
for use with this compressor. Start compressor in
heated area if outdoor temperatures drop below
32° F. If this is not practical, drain out the old
pump oil and use L-PAB100-150 Non-detergent
Air Compressor Oil in the pump crankcase instead
whenever the compressor’s temperature will fall
below 40°. Do not use multi-viscosity oil (such
as 10W-30), they leave carbon deposits on pump
components and lead to accelerated failure. Heavy
operation may require heavier viscosity oil.
3. If uncertain which oil to use for this compressor,
please call Harbor Freight Tools customer
service at 1-888-866-5797 for assistance.
[=J>@>Gk To prevent serious injury from burns:
Do not add or change the oil while
the compressor is in operation.
Allow the compressor to cool before replacing oil.

Follow instructions in a well-ventilated area away from ignition sources.
If the engine is hot from use, shut the engine off and wait for it to cool before proceeding. Do not smoke.
>CE@<6- Warranty void if necessary adjustments are not made for high altitude use.
At high altitudes, the engine’s carburetor, governor (if so equipped), and any other parts that control the fuel-air
ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude use and to prevent damage
to the engine and any other devices used with this product. The fuel system on this engine may be influenced by
operation at higher altitudes. Proper operation can be ensured by installing an altitude kit at altitudes higher than
3000 ft. above sea level. At elevations above 8000 ft, the engine may experience decreased performance, even
with the proper main jet. Operating this engine without the proper altitude kit installed may increase the engine’s
emissions and decrease fuel economy and performance. The kit should be installed by a qualified mechanic.
1. Turn off the engine.
2. Close the fuel valve.
3. Place a bowl under the fuel cup to catch any spilled fuel.
<=;E@C>\ Carburetor bowl may have gas in it which will leak upon removing the bolt.
4. Unthread the bolt holding the fuel cup.
5. Remove the bolt, Bolt Seal, fuel cup, Fuel Cup Seal and Main Jet from the body of the carburetor assembly.
A carburetor screwdriver (not included) is needed to remove and install the Main Jet.
>&$*- The mixing tube is held in place by the Main Jet and might fall out when it is removed.
If it falls out, replace it in the same orientation before replacing the Main Jet.
6. Replace the Main Jet with the replacement Main Jet needed for your altitude range (part 1a or 2a).
>&$*- The Fuel Cup Seal and Bolt Seal may be damaged during removal
and should be replaced with the new ones from the kit.
7. Replace the Fuel Cup Seal (4a), fuel cup, Bolt Seal (3a), and bolt. Tighten in place.
>CE@<6- Do not cross thread bolt when tightening.
Finger tighten first and then use a wrench to make sure the bolt is properly threaded.
8. Wipe up any spilled fuel and allow excess to evaporate
before starting engine. To prevent FIRE, do not start the
engine while the smell of fuel hangs in the air.

The California Air Resources Board and Harbor Freight Tools (HFT) are pleased to explain the emissions
control system warranty on your 2017 Small Off-Road Engine. In California, new equipment that uses small off-
road engines must be designed, built, and equipped to meet the State’s stringent anti-smog standards. HFT must
warrant that the emissions control system on your engine will be free from defects in material and workmanship
for two (2) years, provided there has been no abuse, neglect, or improper maintenance of your engine. HFT also
warrants that the emissions control system on your engine is designed, built, and equipped so that it conforms to the
United States Environmental Protection Agency’s (EPA) emissions requirements in effect at the time of manufacture.
Your emissions control system may include parts such as the carburetor or fuel-injection system, the ignition
system, catalytic converter, fuel lines, fuel caps, valves, canisters, vapor hoses, clamps, connectors, and other
emissions-related assemblies.
Where a warrantable condition exists, HFT will repair or replace, at our option, your engine if at no cost to you,
including diagnosis, parts and labor.

This emissions control system is warranted for two years. If any emission-related part on your engine is
defective, the part will be repaired or replaced by HFT.

a part has failed due to abuse (including failure to follow the fuel use instructions contained in this manual), neglect,
improper maintenance, or unapproved modifications.

a) The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser. The
warranty period is two years.
b) HFT warrants to the initial owner and each subsequent owner that the engine is:
1. Designed, built, and equipped so as to conform with all applicable regulations adopted by the Air Resources
Board; and
2. Free from defects in materials and workmanship that causes the failure of a warranted part for a period of
two years.
c) The warranty on emissions-related parts is as follows:
1. Any warranted part that is not scheduled for replacement as required maintenance in the written instructions
provided, is warranted for the warranty period stated above. If any such part fails during the period of
warranty coverage, it will be repaired or replaced HFT. Any such part repaired or replaced under the
warranty will be warranted for the remaining warranty period.
2. Any warranted part that is scheduled only for regular inspection in the written instructions is warranted for
the warranty period stated above. A statement in the written instructions to the effect of “repair or replace
as necessary” does not reduce the period of warranty coverage. Any such part repaired or replaced under
warranty will be warranted for the remaining warranty period.
3. Any warranted part that is scheduled for replacement as required maintenance in the written instructions will
be warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails
prior to the first scheduled replacement, the part will be repaired or replaced by HFT. Any such part repaired
or replaced under warranty will be warranted for the remainder of the period prior to the first scheduled
replacement point for the part.
4. Repair or replacement of any warranted part under the warranty will be performed at no charge to the owner
at a retail store or by HFT paying for shipping the product for repair.
5. Notwithstanding the provisions herein, warranty services or repairs will be provided at all retail stores or by
contacting HFT product support at 1-888-866-5797 or predator@harborfreight.com.
6. The owner will not be charged for diagnostic labor that leads to the determination that a warranted part is in
fact defective, provided that such diagnostic work is performed at a retail store.
7. HFT is liable for damages to other engine components proximately caused by a failure under warranty of any
warranted part.
8. Throughout the emissions warranty period stated above, HFT will maintain a supply of warranted parts
sufficient to meet the expected demand for such parts.
9. Any replacement part may be used in the performance of any warranty maintenance or repairs and will be
provided without charge to the owner. Such use will not reduce the warranty obligations of HFT.
10. Add-on or modified parts that are not approved by HFT may not be used. The use of any non-exempted add-
on or modified parts will be grounds for disallowing a warranty claim. HFT is not liable to warrant failures of
warranted parts caused by the use of a non-exempted add-on or modified part.
