BEFORE OPERATION IS YOUR ENGINE READY TO GO? For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the engine to check its condition. Be sure to take care of any problem you find, or have your servicing dealer correct it, before you operate the engine.
BEFORE OPERATION Check the Engine Check the engine oil level (see page 21). Running the engine with a low oil level can cause engine damage. Check the air filter (see page 26). A dirty air filter will restrict air flow to the carburetor, reducing engine performance.
SAFE OPERATING PRECAUTIONS the lMPORTANT Before operating the engine for the first time, please review SAFETY INFORMATION on page 5 and the chapter titled BEFORE OPERA- TION.

SERVICING YOUR HONDA ENGINE MAINTENANCE SAFETY Some of the most important safety precautions follow. However, we cannot warn you of every conceivable hazard that can arise in performing mainte- nance. Only you can decide whether or not you should perform a given task.
Service more frequently when used in dusty areas. (2) These items should be serviced by your servicing dealer, unless you have the proper tools and are mechanically proficient. Refer to the Honda shop manual for service procedures. (3) For commercial use, hours of operation to determine proper mainte- nance intervals.
SERVICING YOUR HONDA ENGINE FUEL RECOMMENDATIONS Use LPG with a propane content 95% or higher. This engine is certified to operate on LPG only. Occasionally you may hear a light “spark knock” or “pinging” (metallic rapping noise) while operating under heavy loads. This is no cause for concern.
SERVICING YOUR HONDA ENGINE ENGINE OIL LEVEL CHECK Check the engine oil level with the engine stopped and in a level position. 1. Remove the oil filler cap/dipstick and wipe it clean. 2. Insert and remove the dipstick without screwing it into the filler neck. Check the oil level shown on the dipstick.
SERVICING YOUR HONDA ENGINE ENGINE OIL CHANGE Drain the used oil while the engine is warm. Warm oil drains quickly and completely. 1. Place a suitable container below the engine to catch the used oil, then remove the oil filler cap/dipstick and the drain bolt.
Discard the used oil filter. SEAL NOTICE Use only a genuine Honda oil filter or a filter of equivalent quality specified for your model. Using the wrong filter, or a non-Honda filter which is not of equivalent quality, may cause engine damage.
SERVICING YOUR HONDA ENGINE 4. Screw on the new oil filter by hand until the seal contacts the filter mounting base, then use an oil filter wrench to tighten the filter an additional 718 turn. Oil filter tightening torque: 16 ft-lb (22 Nom, 2.2 kg-m).
Oil is a major factor affecting performance and service life. Use 4-stroke automotive detergent oil that is designed for engines operating on LPG. SAE 30 (API service classification SG minimum) is recommended for general use. The following are examples of oils that meet Honda's requirements for LPG-fueled engines: Pennzoil HD 30...
SERVICING YOUR HONDA ENGINE AIR FILTER INSPECTION Remove the air cleaner cover and inspect the filter elements. Clean or replace dirty filter elements. Always replace damaged filter elements. Refer to page 27 for instructions that apply to the air cleaner and filter.
SERVICING YOUR HONDA ENGINE AIR CLEANER SERVICE A dirty air filter will restrict air flow to the carburetor, reducing engine performance. If you operate the engine in very dusty areas, clean the air filter more often than specified in the MAINTENANCE SCHEDULE (see page 19).
SERVICING YOUR HONDA ENGINE 5. Clean the air filter elements if they are to be reused. Paper filter element: Tap the filter element several times on a hard surface to remove dirt, or blow compressed air [not exceeding 30 psi (207 kPa, 2.1 kg/cm2)] through the filter element from the air cleaner cover side.
SERVICING YOUR HONDA ENGINE SPARK PLUG SERVICE Recommended spark plugs: BPR5ES (NGK) WIGEPR-U (DENSO) NOTICE Incorrect spark plugs can cause engine damage. 1. Disconnect the spark plug caps, and remove any dirt from around the spark plug area. 2. Remove the spark plugs with a 13/1 &inch spark plug wrench.
SERVICING YOUR HONDA ENGINE 6. After the spark plug seats, tighten with a 13/16-inch spark plug wrench to compress the washer. If reinstalling the used spark plug, tighten 1/8-1/4 turn after the spark plug seats. If installing a new spark plug, tighten 112 turn after the spark plug seats.
Your engine is not factory-equipped with a spark arrester. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. A spark arrester is available from authorized Honda servicing dealers. The spark arrester must be serviced every 100 hours to keep it functioning as designed.
SERVICING YOUR HONDA ENGINE 3. Use a brush to remove carbon deposits from the spark arrester screen. Be careful to avoid damaging the screen. The spark arrester must be free of breaks and holes. Replace the spark arrester if it is damaged.
HELPFULTIPS SUGGESTIONS STORING YOUR ENGINE Storage Preparation Proper storage preparation is essential for keeping your engine troublefree and looking good. The following steps will help to keep rust and corrosion from impairing your engine’s function and appearance, and will make the engine easier to start when you use it again.
HELPFULTIPS & SUGGESTIONS Engine Oil 1. Change the engine oil (see page 22). 2. Remove the spark plugs (see page 29). 3. Pour a tablespoon (5-10 cc) of clean engine oil into the cylinders. 4. Pull the starter rope several times to distribute the oil in the cylinders. 5.
HELPFULTIPS & SUGGESTIONS Position the equipment so the engine is level. Tilting can cause oil leakage. With the engine and exhaust system cool, cover the engine to keep out dust. A hot engine and exhaust system can ignite or melt some materials. Do not use sheet plastic as a dust cover.

TECHNICAL & CONSUMER INFORMATION Battery Connections Use a 12-volt battery with an ampere-hour rating of at least 35 Ah. Be careful not to connect the battery in reverse polarity, as this will short circuit the battery charging system. Always connect the positive (+) battery cable to the battery terminal before connecting the negative (-) battery cable, so your tools cannot cause a short circuit if they touch a grounded part while tightening the positive (+) battery cable end.
TECHNICAL & CONSUMER INFORMATION Remote Control Linkage The throttle and choke control levers are provided with holes for optional cable attachment. Remove the two 6 mm special bolts from the control cover and remove the control cover. 6 mm SPECIAL BOLTS TROL COVER The following illustrations show installation examples for asolid wire cable.
Carbon monoxide does not react in the same way, but it is toxic. Honda utilizes systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons. The California Clean Air Act California regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emission control systems.
The emission control systems on your Hondaengine were designed, built, and certified to conform with California emission regulations. We recommend the use of genuine Honda parts whenever you have maintenance done. These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance.
