Kohler SV530 Generator Set

⚠ Drehzahlreglereinstellungen nicht verändern; Überdrehen ist gefährlich.

Tools: Zange, Schraubenschlüssel

1. Gasgestänge von Reglerhebel und Gashebel am Vergaser angeschlossen prüfen.
2. Befestigungsmutter des Drehzahlhebels an der Reglerwelle lösen.
3. Drehzahlhebel so weit wie möglich in Richtung Vergaser (Vollgas) bewegen und halten.
4. Reglerwelle mit einer Zange greifen und so weit wie möglich gegen den Uhrzeigersinn drehen.
5. Mutter mit 7,0-8,5 Nm (60-75 in. lb.) festziehen.

⚠ Do not tamper with governor setting. Overspeed is hazardous and could cause personal injury.

Tools: Pliers, Torque wrench

1. Make sure throttle linkage is connected to governor arm and throttle lever on carburetor.
2. Loosen nut holding governor lever to cross shaft.
3. Move governor lever toward carburetor as far as it will go (wide open throttle) and hold in this position.
4. Grasp cross shaft with pliers, and turn shaft counterclockwise as far as it will go. Torque nut to 7.0-8.5 N·m (60-75 in. lb.).

Tools: Tachometer, Screwdriver

1. Make sure throttle cable is adjusted properly.
2. Start engine and allow it to warm up. Place throttle control lever into fast or high speed position.
3. Turn choke adjusting screw out/counterclockwise so there is clearance from choke lever.
4. Loosen speed control bracket mounting screws. Slide bracket forward or backward until desired high speed (RPM) is reached.
5. To increase RPM, move bracket toward carburetor; to decrease, move bracket away from carburetor.
6. Tighten speed control bracket mounting screws. Recheck speed with a tachometer and readjust if necessary.
7. Adjust choke.

⚠ Torque Torx screw only to prevent damage to nut.

Tools: Feeler gauge, T15 Torx, Torque wrench, Wrench

1. Position push rod guide plates on cylinder head with extruded edges down over push rod bores. Secure by installing rocker arm pivot studs. Torque studs to 13.5 N·m (120 in. lb.).
2. Apply grease to contact surfaces of rocker arms and adjusting nuts and install them onto pivot studs.
3. Apply grease to ends of push rods. Insert push rods into push rod bores and seat lower end into dimpled recess of cam levers.
4. With engine at TDC of compression stroke, insert correct size flat feeler gauge between appropriate valve stem and rocker arm.
5. Tighten adjustment nut with a wrench until a slight drag is felt on feeler gauge.
6. Hold nut in position and torque set screw (T15 Torx drive) to 5.5 N·m (50 in. lb.).
7. Perform adjustment procedure on other valve.

⚠ Carburetor adjustments should be made only after engine has warmed up.

Tools: Tachometer

1. Place throttle control into idle or slow position.
2. Turn low idle speed adjusting screw in or out to obtain idle speed of 1200 RPM (± 75 RPM).

⚠ Nur die Torx-Schraube anziehen, um die Mutter nicht zu beschädigen.

Tools: Fühlerlehre, T15 Torx, Schraubenschlüssel

1. Motor auf oberen Totpunkt des Kompressionshubs bringen.
2. Fühlerlehre passender Dicke zwischen Ventilschaft und Kipphebel einsetzen.
3. Einstellmutter mit Schraubenschlüssel festziehen, bis leichter Widerstand an der Fühlerlehre spürbar ist.
4. Mutter in dieser Stellung halten und Stellschraube (T15 Torx) mit 5,5 Nm (50 in. lb.) festziehen.
5. Einstellung am anderen Ventil wiederholen.

⚠ Avoid inhaling exhaust fumes; carbon monoxide can cause death. Stay away while engine is in operation.

Tools: Water manometer or vacuum/pressure gauge, Rubber stopper

1. Insert rubber stopper into oil fill hole. Connect hose between stopper and one manometer tube; leave other tube open to atmosphere.
2. Check water level in manometer is at 0 line. Make sure pinch clamp is closed.
3. Start engine and run no-load high speed.
4. Open clamp and note water level in tube. Engine side should be a minimum of 10.2 cm (4 in.) above open side.
5. Close pinch clamp before stopping engine.

Tools: Cylinder leakdown tester, Adapter, Holding tool

1. Run engine for 3-5 minutes to warm it up.
2. Remove spark plug(s) and air filter from engine.
3. Rotate crankshaft until piston is at TDC of compression stroke. Hold engine in this position while testing.
4. Install adapter into spark plug hole, but do not attach it to tester at this time.
5. Turn regulator knob completely counterclockwise.
6. Connect an air source of at least 50 psi to tester.
7. Turn regulator knob clockwise until gauge needle is in yellow set area at low end of scale.
8. Connect tester quick-connect to adapter hose. Firmly hold engine at TDC and gradually open tester valve.
9. Note gauge reading and listen for escaping air at combustion air intake, exhaust outlet, and crankcase breather.

⚠ Gasoline will leak out of carburetor when solenoid is loosened and removed.

Tools: 12 volt switched power source

1. Shut off fuel and remove solenoid from carburetor. Have container ready to catch fuel.
2. Wipe tip of solenoid to remove any remaining fuel. Work in a well ventilated area with no fuel vapors.
3. Connect positive power source lead to red lead of solenoid; connect negative lead to solenoid body.
4. Turn power source ON. Pin should retract with power ON and return to original position with power OFF. Test several times.

⚠ Explosive Fuel can cause fires and severe burns.

1. Check for fuel in combustion chamber: disconnect and ground spark plug lead, close choke, crank engine several times, remove spark plug and check for fuel at tip.
2. Check fuel flow from tank to fuel pump: remove fuel line from inlet fitting of fuel pump; hold line below bottom of tank; open shut-off valve and observe flow.
3. Check operation of fuel pump: remove fuel line from inlet fitting of carburetor; crank engine several times and observe flow.

1. Check for fuel in combustion chamber. Disconnect and ground spark plug lead. Close choke on carburetor. Crank engine several times. Remove spark plug and check for fuel at tip.
2. Check for fuel flow from tank to fuel pump. Remove fuel line from inlet fitting of fuel pump. Hold line below bottom of tank. Open shut-off valve (if equipped) and observe flow.
3. Check operation of fuel pump. Remove fuel line from inlet fitting of carburetor. Crank engine several times and observe flow.

Tools: Rohrmanometer, Gummistopfen, Schlauchquetschvorrichtung

1. Gummistopfen in Öleinfüllöffnung einsetzen; Rohrmanometer anschließen; Wasserfüllung auf Nulllinie prüfen.
2. Motor starten und mit erhöhter Leerlaufdrehzahl laufen lassen.
3. Klemme öffnen und Wasserstand im Rohr ablesen.
4. Mindestens 10,2 cm (4 in.) höher als auf der offenen Seite erforderlich.
5. Bei zu niedrigem Unterdruck oder Überdruck Fehlersuchtabelle prüfen.
6. Schlauchquetschvorrichtung schließen, bevor der Motor abgestellt wird.
