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.

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.
