servIce precautIons
1. Before service, maintenance, or
cleaning:
a. turn the engine switch to its
“oFF” position.
b. allow the engine to completely
cool.
14. Do not operate the equipment with
known leaks in the engine’s fuel sys-
tem.
c. then, remove the spark plug
wire(s) from the spark plug(s).
2. Keep all safety guards in place and in
proper working order. Safety guards
include muffler, air cleaner, mechani-
cal guards, and heat shields, among
other guards.
15. This product contains or, when used,
produces a chemical known to the
State of California to cause cancer
and birth defects or other reproduc-
tive harm. (California Health & Safety
Code § 25249.5, et seq.)
3. do not alter or adjust any part of
the equipment or its engine that is
sealed by the manufacturer or dis-
tributor. Only a qualified service
technician may adjust parts that
may increase or decrease gov-
erned engine speed.
16. When spills of fuel or oil occur, they
must be cleaned up immediately. Do
not leave fuel, or oil soaked rags sit-
ting around, even for short periods
of time. Dispose of (or store) any
fuel, or oil soaked rags in a bottom-
ventilated, covered, metal container.
Dispose of fluids and cleaning materi-
als as per any local, state, or federal
codes and regulations.
4. Wear ANSI-approved safety goggles,
heavy-duty work gloves, and dust

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.
a. Do not smoke, or allow sparks,
flames, or other sources of ignition
around the equipment, especially
when refuelling.
b. Do not refill the fuel tank while the
engine is running or hot.
c. Do not fill fuel tank to the top. Leave
a little room for the fuel to expand as
needed.
d. Refuel in an exterior, well-ventilated
area only.

1. Wait for engine to cool, then clean
engine with clean cloth.
2. When the equipment is to remain idle
for longer than 20 days, prepare the
engine for storage as follows:
a. Change engine oil and empty fuel
tank.
b. Either leave fuel tank empty or
refill fuel tank with fresh unleaded
gasoline. After filling, run engine
for about 5-10 minutes to circulate
the gasoline through the carburetor.
Wait for engine to cool before pro-
ceeding.
c. Clean out area around spark plug.
Remove spark plug and pour one
tablespoon of engine oil into cylinder
through spark plug hole.
d. Reinstall spark plug, but leave spark
plug wire disconnected.
e. Pull recoil starter to distribute oil in
cylinder. Stop after one or two revo-
lutions when you feel the piston start

start to feel resistance).
f. Disconnect battery cables (if
equipped).
3. Cover and store in a dry, well-ventilat-
ed area out of reach of children.
4. Before starting the engine after stor-
age, keep in mind that untreated gas-
oline will deteriorate quickly. Drain
the fuel tank and filter, and change
to fresh fuel if untreated gasoline has
been sitting for a month, if treated
gasoline has been sitting beyond the
fuel stabilizer’s recommended time
period, or if the engine does not start

HfT warrants to a first retail purchaser and each subsequent

first retail purchaser.
The CaliforniaAir Resources Board (herein CARB), the United
States Environmental ProtectionAgency (herein EPA), and Harbor
Freight Tools (herein HFT) are pleased to explain the emission con-
trol 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.
2. no charge repair or replacement
Repair or replacement of any warranted part will be performed
at no charge to the owner if the work is performed through a

service, contact the HFT Customer Service Department at
1-800-444-3353.
3. consequential damages coverage
Coverage under this warranty shall also extend to the failure
of any engine components caused by the failure of any war-

included may be hoses, belts, connectors and other emission-
related assemblies.
4. coverage exclusions
Warranty claims shall be filed in accordance with the provi-
sions of the HFT warranty policy explained in the box at the
top of the previous page. HFT shall not be liable for any loss
of use of the engine, for any alternative usage, for any damage
to goods, loss of time, or inconvenience. Warranty coverage
shall also be excluded for any part which fails, malfunctions,
or is damaged due to failure to follow the maintenance and
operating instructions set forth in the Owner’s Manual includ-
ing, but not limited to:

are warranted for the warranty period. Any warranted part
which is scheduled for replacement as required maintenance
is warranted for the period of time up to the first scheduled
replacement point for that part. Any replacement part, pro-
vided it is equivalent in durability and performance, may be
used in performance of maintenance or repairs. The owner
is responsible for commissioning a qualified technician/me-
chanic to perform all required maintenance, as outlined in
the Inspection, Cleaning, and Maintenance section in this
manual.
• As the engine owner, you should, however, be aware that
HFT may deny you warranty coverage if your engine or a part

ranty station as soon as a problem exists. Contact the HFT
