3. Setup

3.1 Unpacking and Inspection:

• Carefully remove the generator from its packaging.
• Inspect for any shipping damage. Contact your dealer immediately if damage is found.
• Ensure all accessories listed in the packing list are present.

3.2 Adding Engine Oil:

The generator is shipped without engine oil. It is crucial to add the correct type and amount of oil before first use.

1. Place the generator on a level surface.
2. Locate and remove the oil fill cap/dipstick.
3. Add recommended engine oil (e.g., SAE 10W-30) to the crankcase until it reaches the upper mark on the dipstick. Do not overfill.
4. Securely replace the oil fill cap/dipstick.

3.3 Adding Fuel:

Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 fuel or oil/gasoline mixtures.

1. Ensure the generator is off and cool.
2. Open the fuel tank cap.
3. Slowly add gasoline to the fuel tank, being careful not to overfill. The tank capacity is 3.2 gallons.
4. Securely replace the fuel tank cap. Wipe up any spilled fuel immediately.

3.4 Battery Connection:

The PG4500iSR includes a lithium-ion battery for electric start. Ensure it is properly connected before use.

• Locate the battery compartment.
• Connect the positive (+) terminal (red cable) and negative (-) terminal (black cable) securely.
• Ensure the battery switch is in the "ON" position for electric and remote start functionality.

4. Operating Instructions

4.1 Starting the Generator:

Before starting, ensure the generator is on a level surface, away from any obstructions, and all electrical devices are disconnected from the outlets.

1. Turn the fuel valve to the "ON" position.
2. Ensure the engine switch is in the "ON" position.
3. For Electric Start: Press and hold the "START" button on the control panel until the engine starts.
4. For Remote Start: Use the wireless remote control. Press the "START" button on the remote. The generator can be started from up to 80 feet away.
5. For Manual (Recoil) Start: If electric or remote start is unavailable, pull the recoil starter handle firmly and smoothly until the engine starts.
6. Allow the engine to warm up for a few minutes before connecting electrical loads.

4.2 Parallel Operation:

The Pulsar PG4500iSR is equipped with parallel capability, allowing you to connect two identical units to double your power output. A parallel kit (sold separately) is required for this function.

1. Ensure both generators are off and cool.
2. Connect the parallel kit cables to the designated parallel operation outlets on both generators.
3. Start both generators according to the instructions in Section 4.1.
4. Once both generators are running stably, you can connect your electrical loads to the outlets on the parallel kit.

4.3 Economy Mode:

The Economy Mode switch, when activated, allows the engine speed to automatically adjust to the load. This feature improves fuel efficiency and reduces noise levels during periods of low power demand.

• Turn the Economy Mode switch to "ON" for fuel efficiency and quieter operation.
• Turn the Economy Mode switch to "OFF" when maximum power is required or when operating sensitive electronics that require a constant engine speed.

4.4 Stopping the Generator:

1. Disconnect all electrical loads from the generator outlets.
2. Allow the generator to run for a few minutes without load to cool down.
3. Turn the engine switch to the "OFF" position.
4. Turn the fuel valve to the "OFF" position.

5. Maintenance

Regular maintenance is essential for the longevity and optimal performance of your generator. Always refer to the detailed maintenance schedule in the complete owner's manual.

5.1 Routine Checks (Before Each Use):

• Check engine oil level and add if necessary.
• Inspect the air filter for dirt or debris; clean or replace if needed.
• Check fuel level.
• Inspect for any loose fasteners or damaged components.

5.2 Storage:

For extended storage (more than 30 days), proper preparation is necessary to prevent fuel degradation and engine damage.

1. Add a fuel stabilizer to the fuel tank and run the engine for a few minutes to circulate it.
2. Drain the carburetor bowl (refer to the full manual for specific instructions).
3. Change the engine oil.
4. Remove the spark plug and pour a small amount of engine oil into the cylinder. Pull the recoil starter a few times to distribute the oil, then reinstall the spark plug.
5. Clean the exterior of the generator.
6. Store in a clean, dry, well-ventilated area.
