IMPORTANT: Allow the engine to run for five minutes with no load after each start‑up so that the engine can stabilize.
Maintenance Break-in Period:
Breaking-in the engine will help to ensure proper equipment and engine operation.
The maintenance break‑in period will last about 20 hours of use. After this period, change the engine oil.
SETUP
Under normal operating conditions, subsequent maintenance follows the schedule
explained in the MAINTENANCE AND SERVICING section.
Note: When maximum tank pressure is reached, the compressor automatically disengages, and the engine
RPM drops down to idle speed. The engine remains at idle until Air Tank pressure falls to a preset level.
The Gas Engine will then accelerate and air pressure once again begins to build up in the Air Tank.
Note: As long as the engine is running, the operation of the Air Compressor
is automatic, controlled by an internal pressure switch.
IMPORTANT: The internal pressure switch is not user adjustable; do not make changes to the
air pressure settings of the internal pressure switch. Any change to the automatic pressure
levels may cause excess pressure to accumulate, causing a hazardous situation.

Many maintenance procedures, including any not detailed in this manual, will need to be performed by a
qualified technician for safety. If you have any doubts about your ability to safely service the equipment
or engine, have a qualified technician service the equipment instead.
SETUP
Compressor Pump Oil Maintenance
Check oil periodically for clarity. Replace oil if it appears milky or if debris is present, or every
6 months, or 100 hours of runtime, whichever comes first. In harsh environments such as
high heat or high humidity, you will need to replace the oil more frequently.
Change the compressor oil after the first hour of use to remove any debris.
Adding Oil
OIL LEVEL
OVERFILL
FULL
LOW
1. The oil level should be at the center of the “full” level
on the Oil Sight Glass, as shown above. Add oil as
needed to maintain this level. Do not let the oil level
go below the center dot (LOW as shown above) and
do not overfill the oil so that it is above the center dot
(OVERFILL as shown above) on the Oil Sight Glass.
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 SAE 10W 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 1-800‑444-3353 for assistance.
WARNING! 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.
2. To add oil:

the FULL level on the Oil Sight Glass.
6. Replace and tighten the Oil Plug.
7. Discard the old oil according to local,
state and federal regulations.
Draining Moisture from the Tank
The Drain Valve is located under the Tank. It must be
accessed daily to release all trapped air and moisture
from the Tank. This will eliminate condensation which can
cause tank corrosion. To empty the air and condensation:
1. Make sure the compressor engine is off.
2. Place a collection pan under the Drain Valve.
3. Open the Drain Valve by pivoting the lever
on the bottom of the Compressor so the
lever is in line with the Drain Valve.

4. When all the pressure is released, close
the Drain Valve by pivoting the lever on the
bottom of the compressor so that the lever
is perpendicular to the Drain Valve.
Air Filter Maintenance
Check the Air Filter weekly to see if it needs replacement.
If working in dirty environments, you may need to
replace the filter more often. To replace the Air Filter:
1. Unthread the Wing Nut holding the
Air Filter Assembly in place.
2. Remove the Air Filter Assembly.
3. Replace with a new Air Filter.
4. Secure in place with the Wing Nut.

Air Filter Element Maintenance
Spark Plug Maintenance
1. Remove the air filter cover and the air filter elements
and check for dirt. Clean or replace as described below.
SAFETY
2. Cleaning:
• For “paper” filter elements:
To prevent injury from dust and debris, wear ANSIapproved safety goggles, NIOSH‑approved dust
mask/respirator, and heavy-duty work gloves. In
a well-ventilated area away from bystanders, use
pressurized air to blow dust out of the air filter.
If this does not get the filter clean, replace it.
• For foam filter elements:
Wash the element in warm water and mild
detergent several times. Rinse. Squeeze out
excess water and allow it to dry completely.
Soak the filter in lightweight oil briefly,
then squeeze out the excess oil.
SETUP
3. Install the new filter or the cleaned filter.
Secure the Air Cleaner Cover before use.
Spark
Plug
Cap
1. Disconnect spark plug cap from end of plug.
Clean out debris from around spark plug.
2. Using a spark plug wrench, remove the spark plug.
3. Inspect the spark plug:
If the electrode is oily, clean it using a clean, dry
rag. If the electrode has deposits on it, polish it
using emery paper. If the white insulator is cracked
or chipped, the spark plug needs to be replaced.
Use only NHSP®/Torch® F6TC spark plug.
NOTICE: Using an incorrect spark
plug may damage the engine.
4. When installing a new spark plug, adjust the
plug’s gap to the specification on the Technical
Specifications chart. Do not pry against the
electrode, the spark plug can be damaged.
OPERATION
5. Install the new spark plug or the cleaned spark plug
into the engine. Gasket-style: Finger-tighten until the
gasket contacts the cylinder head, then tighten about
1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until the plug contacts
the head, then tighten about 1/16 turn more.
NOTICE: Tighten the spark plug properly.
If loose, the spark plug will cause the engine
to overheat. If overtightened, the threads
in the engine block will be damaged.

Harbor Freight Tools Emission Control Defects
Warranty Coverage
The California Air Resources Board (herein CARB), the United
States Environmental Protection Agency (herein EPA), and Harbor Freight
Tools (herein HFT) are pleased to explain the emission control system
warranty on your 1995 and later Small Off-Road Engine (herein engine).
In California, the engine must be designed, built and equipped to meet
the State’s stringent anti-smog standards. Elsewhere within the United
States, new off-road, spark-ignition engines certified for model year 1997
and later, must meet similar standards set forth by the EPA. HFT must
warrant the emission control system on your engine for the periods of time
described below, provided there has been no abuse, neglect or improper
maintenance of your engine.
Engines are warranted for a period of two (2) years relative to
emission control parts defects, subject to the provisions set forth below.
If any emission related part on your engine is defective, the part will be
repaired or replaced by HFT.
Your emission control system may include parts such as the
carburetor or fuel-injection system, and the ignition system. Also included
may be hoses, belts, connectors and other emission-related assemblies.
Where a warrantable condition exists, HFT will repair your engine at
no cost to you including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage
The 1995 and later engines are warranted for two (2) years. If any
emission-related part on your engine is defective, the part will be repaired
or replaced by HFT.

Owner’s Warranty Responsibilities
• As the engine owner, you are responsible for the performance
of the required maintenance listed in your Owner’s Manual. HFT
recommends that you retain all receipts covering maintenance on
your engine, but HFT cannot deny warranty solely for the lack of
receipts or for your failure to ensure the performance of all scheduled
maintenance.
• As the engine owner, you should, however, be aware that HFT may
deny you warranty coverage if your engine or a part has failed due to
abuse, neglect, improper maintenance, or unapproved modifications.
• You are responsible for shipping your engine to a HFT warranty
station as soon as a problem exists. Contact the HFT Customer
Service department at the number below to make shipping
arrangements. The warranty repairs should be completed in a
reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and
responsibilities, you should contact the Harbor Freight Tools Customer
Service Department at 1-800-520-0882.
