Master Your Power: The Ultimate Pro User G850 Generator Guide

Whether you’re facing a sudden blackout or powering a remote job site, the Pro User G850 Generator is a compact, reliable workhorse designed for portability and efficiency. This guide serves as your comprehensive manual, covering everything from initial setup to long-term maintenance. 1. Technical Specifications at a Glance

Before pulling the starter cord, it’s essential to understand what your G850 can handle. Engine Type: 2-Stroke, Air-cooled. Peak Output: 850 Watts. Continuous Output: 650–700 Watts.

Fuel Type: Unleaded Gasoline + 2-Stroke Oil Mix (typically 50:1 ratio).

Run Time: Approximately 5–6 hours on a full tank (at 50% load). 2. Pre-Operation: The Perfect Fuel Mix

The G850 uses a 2-stroke engine, meaning you cannot pour straight petrol into the tank. You must pre-mix gasoline with high-quality 2-stroke engine oil. The Ratio: Most Pro User models require a 50:1 ratio. 5 Litres of Gasoline + 100ml of 2-Stroke Oil.

Tip: Always mix the fuel in a dedicated container before pouring it into the generator tank to ensure even distribution. 3. Starting Your G850 Generator Follow these steps to ensure a smooth start every time: Check Fuel: Ensure the tank is filled with the correct mix.

Vent the Cap: Ensure the fuel cap vent is open (if applicable). Turn on Fuel Tap: Move the fuel lever to the "ON" position.

Engage the Choke: Slide the choke lever to the "CLOSE" or "START" position. Power Switch: Flip the engine switch to "ON."

The Pull: Gently pull the starter cord until you feel resistance, then give it a sharp, steady tug.

Warm Up: Once the engine starts, gradually move the choke lever to "RUN" or "OPEN" as the engine stabilizes. 4. Connecting Your Devices

The G850 is ideal for small appliances, lights, and power tools. However, it is not an inverter generator.

Sensitive Electronics: Exercise caution when plugging in laptops or smartphones. Use a high-quality surge protector to shield against voltage fluctuations.

Wattage Calculation: Ensure the "Starting Watts" of your appliances don't exceed 850W. Items with motors (like small fridges) often need 2–3 times their running wattage just to start up. 5. Maintenance Schedule

To keep your Pro User G850 running for years, follow this simple checklist:

Spark Plug: Inspect every 50 hours of use. Clean off carbon deposits and ensure the gap is set correctly (refer to your physical manual for exact gap specs, usually around 0.6mm–0.7mm).

Air Filter: Clean the foam element every 20 hours. Wash with soapy water, dry thoroughly, and add a few drops of engine oil. pro user g850 generator manual

Storage: If you aren't using the generator for more than 30 days, drain the fuel tank. 2-stroke mix can "gum up" the carburetor if left sitting. 6. Common Troubleshooting

Engine won’t start? Check if the spark plug is "wet" (flooded). Remove it, wipe it dry, and try again.

Engine runs rough? Your fuel mix might be old or the air filter might be clogged.

No electrical output? Check the DC or AC circuit breaker on the front panel; it may have tripped due to an overload. Safety First

Carbon Monoxide Kills: Never run your G850 indoors, in a garage, or near open windows. Always operate it outdoors in a well-ventilated area.

Grounding: Use the grounding terminal on the faceplate to properly ground the unit before use.

By following this manual, you’ll ensure your Pro User G850 remains a dependable source of power whenever you need it most.

Mixture Ratio: Use a 50:1 ratio of unleaded petrol to high-quality 2-stroke engine oil.

Preparation: Always mix the fuel and oil in a separate, clean container before pouring it into the generator's tank. Do not mix them inside the generator tank, as this can lead to an uneven mixture and engine damage. Starting Procedure

Safety Check: Place the generator on a flat surface in a well-ventilated outdoor area. Never run it indoors or in a garage due to carbon monoxide risks.

Fuel Valve: Turn the fuel petcock (fuel lever) to the ON position. Choke: Move the choke lever to the START (closed) position. Power Switch: Turn the engine's main power switch to ON.
