KAWASAKI FS730V (02) PDF DOCUMENT

For your safety, please adhere to the following warnings when operating your KAWASAKI FS730V engine:

Exhaust Fumes: DO NOT run the engine in a closed area. Exhaust gas contains carbon monoxide, an odorless and deadly poison.

Fuel Handling: Gasoline is extremely flammable and can be explosive. Stop the engine and allow it to cool before refueling. DO NOT smoke. Refuel in a well-ventilated area free from flames or sparks. DO NOT overfill the tank. Wipe off any spilled gasoline immediately.

Fire Prevention: Keep the engine at least 1 m (3.3 ft) away from buildings and other burnable objects. DO NOT place flammable objects close to the engine or expose combustible materials to the exhaust.

Electric Shock: To avoid electric shock, DO NOT touch spark plugs, plug caps, or spark plug leads while the engine is running.

Burn Prevention: DO NOT touch a hot engine or muffler. Allow the engine to cool before servicing or removing parts.

Moving Parts: DO NOT place hands or feet near moving or rotating parts. Ensure a protective cover is over the pulley, V belt, or coupling.

Engine Speed: DO NOT run the engine at excessive speeds, as this may result in injury.

Servicing: Always remove the spark plug caps from the spark plugs when servicing the engine to prevent accidental starting.

The KAWASAKI FS730V engine is certified to operate on unleaded regular grade gasoline only. Use clean, fresh gasoline with a minimum of 87 octane (antiknock index). If “knocking or pinging” occurs, use a different brand of gasoline or a higher octane rating.

Oxygenated Fuel:

If you use oxygenated fuel, ensure it is unleaded and meets the minimum octane requirement.

ETHANOL (Ethyl or Grain Alcohol): You may use gasoline containing up to 10% ethanol by volume.

MTBE (Methyl Tertiary Butyl Ether): You may use gasoline containing up to 15% MTBE by volume.

METHANOL (Methyl or Wood Alcohol): You may use gasoline containing up to 5% methanol by volume, as long as it also contains cosolvents and corrosion inhibitors. Gasoline with more than 5% methanol may cause starting/performance problems and damage fuel system parts.

For the KAWASAKI FS730V engine, use oil with an API Service Classification of SF, SG, SH, SJ, or SL. The viscosity should be chosen based on the ambient temperature.

Oil Viscosity Chart:

Although 10W-40 is recommended for most conditions, the viscosity may need to be changed to accommodate atmospheric conditions. Using 20W-50 oil in higher ambient temperatures may reduce oil consumption.

Check the engine oil daily before starting the engine to prevent serious damage like seizure. The engine is shipped without oil.

1. Place the engine on a level surface. Clean the area around the oil gauge before removing it.

2. Remove the oil gauge (A) and wipe it with a clean cloth.

3. If adding oil, pour it slowly to the “FULL” mark on the oil gauge.

4. Insert the oil gauge into its tube (B) WITHOUT SCREWING IT IN.

5. Remove the oil gauge again to check the oil level. The level should be between the “ADD” and “FULL” marks.

6. Do not overfill. Excess oil can cause a smoking condition and may cause the engine to overheat.

7. Install and tighten the oil gauge (A).

1. Before starting, disconnect all possible external loads.

2. Open the fuel valve on the equipment.

3. Move the throttle lever to the half throttle position.

4. Use full choke if the engine is cold. If the engine is warm or in hot weather, use half choke or leave the choke fully open.

5. Insert the key into the engine switch.

6. Turn the switch key to the START position. The engine will usually start within 3 seconds.

CAUTION: Do not run the electric starter continuously for more than 5 seconds, or the battery may discharge quickly. If the engine does not start right away, wait 15 seconds and try again.

7. If the engine is very warm and does not start immediately, DO NOT keep trying with the choke closed as this will cause flooding. Instead, fully open the choke and try to start the engine.

8. After the engine starts, gradually return the choke lever to the fully open position.

After the engine starts, move the throttle lever on the equipment to a position halfway between “FAST” and “SLOW”. To warm up the engine, run it for 3 to 5 minutes in this halfway position before putting the equipment under load. This allows oil to reach all engine parts and for piston clearance to reach design specifications. After warming up, move the throttle lever to its “FAST” position for operation.

Ordinary Stop:

1. Move the throttle lever to the “slow” position.

2. Lower the engine speed to idle and keep it running at idle for about one minute. This prevents engine damage from run-on or after-burning that can occur if the engine is stopped suddenly from a high speed loaded operation.

3. Turn the engine switch or switch key to the “OFF” position.

Emergency Stop:

1. Immediately turn the engine switch or the switch key to the “OFF” position.

2. Close the fuel valve on the equipment.

Throttle Cable Installation and Adjustment:

1. Link the throttle cable (G) to the speed control lever (C) and loosely clamp the throttle cable outer housing (F) with the cable clamp bolt (A).

2. Move the equipment’s throttle lever to the “FAST” position.

3. Pull up the outer housing (F) of the throttle cable until the inner wire (G) has almost no slack, then tighten the cable clamp bolt (A).

4. Move the throttle lever to the “SLOW” position. Make sure that the carburetor throttle valve (H) moves smoothly.

Choke Cable Installation and Adjustment:

1. Link the choke cable (K) to the choke control lever (D), and loosely clamp the choke cable outer housing (L) with the cable clamp bolt (B).

2. Move the equipment choke control to the “OPEN” position. Make sure that the carburetor choke valve (I) is fully opened.

3. Pull up the outer housing (L) of the choke cable until the inner wire (K) has almost no slack, then tighten the cable clamp bolt (B).

4. Move the equipment choke control to the “CHOKE” position. Make sure that the carburetor choke valve (I) is completely closed.

5. Ensure the choke valve turns smoothly from the fully closed to the fully opened position when the equipment choke control is actuated.

Service intervals are a guide. Service more frequently as necessary based on operating conditions, especially in dusty environments. Always remove spark plug caps before servicing to prevent accidental starting.

◆: Service more frequently under dusty conditions.

◇: Service to be performed by an authorized Kawasaki dealer or equally qualified service facility.

Engine Oil Change (Every 100 hours):

1. Run the engine to warm the oil. Ensure the engine is on a level surface.

2. Stop the engine. Allow the engine temperature to drop from hot to warm before draining to avoid burns.

3. Remove the oil drain plugs (A) and drain the oil into a suitable container (B).

4. Install the oil drain plugs.

5. Remove the oil gauge and refill with fresh oil as per recommendations.

6. Check the oil level as described in the “PREPARATION” chapter.

Oil Filter Change (Every 200 hours):

1. Drain the engine oil into a suitable container (C).

2. Place a suitable pan under the filter connection before removing the oil filter.

3. Rotate the oil filter (A) counterclockwise to remove it.

4. Coat the seal of the new filter with a film of clean engine oil.

5. Install the new filter by rotating it clockwise until the seal contacts the mounting surface (B). Then, rotate the filter an additional 3/4 turn by hand.

6. Supply engine oil as specified.

7. Run the engine for about 3 minutes, stop it, and check for any oil leakage around the filter.

8. Add oil to compensate for the oil level drop due to the filter’s capacity, then re-check the oil level.

Engine oil is a toxic substance. Dispose of used oil properly by contacting your local authorities for approved disposal methods.

To prevent excessive engine wear, do not run the engine with the air cleaner removed.

Foam Element (Clean every 25 hours):

Wash the foam element (A) in detergent and water, and then dry it thoroughly.

Paper Element (Clean every 100 hours, Replace yearly or every 200 hours):

Clean the paper element (B) by tapping it gently to remove dust. If it is very dirty, replace it with a new one. Replace the paper element yearly or after 200 hours of use, whichever comes first. Operating in dusty conditions may require more frequent maintenance.

CAUTION:

Do not wash the paper element.

Do not oil the foam or paper element.

Do not use pressurized air to clean the paper element.

Clean or replace the spark plugs and reset the gap every 100 hours of operation. WARNING: Hot engine components can cause severe burns. Stop the engine and allow it to cool before checking spark plugs.

1. Disconnect the spark plug caps from the spark plugs.

2. Remove the spark plugs.

3. Clean the electrodes (B) by scraping with a wire brush to remove carbon deposits.

4. Inspect for cracked porcelain or other wear and damage. Replace the spark plug with a new one if necessary.

5. Check the spark plug gap (A). It must be 0.75 mm (0.030 in). To adjust, bend only the side-electrode using a spark plug tool.

6. Install and tighten the spark plugs to 22 N·m (2.2 kgf·m, 16 ft·lb).

7. Connect the spark plug caps.

Recommended Spark Plug: NGK BPR4ES

Before each use: Check that the air inlet (rotary) screen is free from grass and debris. Clean if necessary.

Every 25 hours (Inspection Port Model): Detach the air cleaner cover and check inside the shroud through the inspection ports. Clean or blow out any debris or dust.

Every 100 hours: Check and clean the cooling fins and the inside of the engine shrouds to remove grass, chaff, or dirt that can clog the cooling system and cause overheating. To perform this cleaning, remove the air cleaner, loosen bolts (C) and (D), and then remove the fan housing (B).

CAUTION: Do not run the engine before all cooling system parts are reinstalled.

Bolts Size and Tightening Torque:

If not operating the engine for more than 30 days, follow these steps:

1. Add fuel stabilizer to the fuel tank and run the engine for 5 minutes.

2. Drain the fuel tank. Afterward, run the engine at low idle until it stalls to empty the carburetor.

3. Fuel System Draining: Clean every part of the engine. Ensure the engine switch is “OFF”. Close the fuel valve, remove the sediment bowl, and place a pan underneath. Open the fuel valve to drain the remaining fuel completely. Then, install the sediment bowl and open the fuel valve.

4. Engine Internals: Remove the spark plugs and pour approx. 1-2 mL (0.06-0.1 cu. in.) of engine oil through the spark plug holes (A). Screw the spark plugs back in after turning the engine a few times. Slowly turn the engine until you feel compression and then leave it there. This blocks air inside the cylinder and prevents rust.

5. Wipe the engine body with an oily cloth.

6. Wrap the engine with plastic sheeting and store it in a dry place.

7. Change the engine oil before the next use.

Note: Specifications are subject to change. Dry weight excludes the fuel tank and muffler.
