1. Introduction
This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your Wolf PowerKing PKB4000LR portable petrol generator. Please read this manual thoroughly before operating the generator to ensure proper use and to prevent injury or damage.
The PowerKing PKB4000LR is a robust 2.8KW (3.5KVA) petrol generator equipped with a 7HP 4-stroke engine, designed to provide a reliable source of electricity. It features two 230V 13Amp outlets and a 12V charging system, an automatic voltage regulator, and a low oil level shut-off system for enhanced safety and durability.
2. Safety Information
WARNING: Failure to follow these safety instructions could result in serious injury or death.
- Carbon Monoxide Hazard: Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operate generators outdoors only, far away from windows, doors, and vents. Never operate in an enclosed space.
- Fire Hazard: Fuel is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator.
- Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded. Never connect the generator directly to a building's electrical system without a transfer switch installed by a qualified electrician.
- Hot Surfaces: The engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact to prevent burns.
- Moving Parts: Keep hands, feet, and clothing away from moving parts.
- Children and Pets: Keep children and pets away from the generator at all times.
- Read Manual: Always read and understand the entire instruction manual before operating the generator.
3. Setup and Initial Preparation
Before starting the generator for the first time, perform the following steps:
- Unpacking and Inspection:
Carefully remove the generator from its packaging. Inspect for any shipping damage. Report any damage to your dealer immediately.
- Add Engine Oil:
The generator is shipped without engine oil. Fill the engine crankcase with the recommended oil (e.g., SAE 10W-30) to the upper mark on the dipstick. Do not overfill. The low oil level shut-off system will prevent the engine from starting or running if the oil level is too low.
Image 1: Low Oil Level System. This image shows a close-up of the generator's engine area, highlighting a yellow warning sticker that indicates the presence of a low oil level shut-off system. This system is crucial for protecting the engine from damage by automatically stopping operation if oil levels are insufficient. Ensure proper oil filling before use.
- Add Fuel:
Fill the fuel tank with fresh, unleaded petrol (gasoline). Do not use old or contaminated fuel. Do not overfill; leave space for fuel expansion. The fuel tank capacity is 15 liters.
WARNING: Do not refuel while the engine is running or hot. Avoid spilling fuel.
- Positioning:
Place the generator on a firm, level surface outdoors in a well-ventilated area, away from combustible materials and at least 1 meter (3 feet) from buildings or other equipment.
4. Operating Instructions
4.1 Starting the Generator (Recoil Start)
- Ensure the generator is on a level surface and has sufficient oil and fuel.
- Turn the engine switch to the "ON" position.
- Open the fuel valve.
- Move the choke lever to the "CHOKE" position (if the engine is cold).
- Grasp the recoil starter handle firmly and pull it slowly until resistance is felt, then pull quickly and smoothly to start the engine. Repeat if necessary.
- Once the engine starts, gradually move the choke lever to the "RUN" position.
- Allow the engine to warm up for a few minutes before connecting electrical loads.
4.2 Connecting Electrical Loads
The generator is equipped with two 230V 13Amp outlets and a 12V DC battery charging output.
Image 2: Control Panel and Outlets. This image displays the front control panel of the generator, featuring two 230V AC 13Amp outlets, a circuit breaker for overload protection, and a 12V DC battery charging output. These are the primary connection points for electrical devices.
- Ensure the total wattage of connected appliances does not exceed the generator's rated output of 2500 watts (maximum 2800 watts).
- Plug appliances directly into the 230V outlets.
- For 12V charging, connect the appropriate cable to the 12V DC output.
- The generator features an Automatic Voltage Regulator (AVR) for stable output.

4.3 Stopping the Generator
- Disconnect all electrical loads from the generator.
- Turn the engine switch to the "OFF" position.
- Close the fuel valve.
5. Maintenance
Regular maintenance is crucial for the longevity and reliable operation of your generator. Always ensure the engine is off and cool before performing any maintenance.
- Engine Oil: Check oil level before each use. Change oil after the first 20 hours of operation, then every 50-100 hours or annually.
- Air Filter: Clean the air filter every 50 hours or more frequently in dusty conditions. Replace if damaged.
- Spark Plug: Inspect and clean the spark plug every 100 hours. Replace if worn or fouled.
- Fuel Filter: Inspect the fuel filter periodically and replace if clogged.
- General Cleaning: Keep the generator clean and free of debris. Ensure cooling fins are clear for proper heat dissipation.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel Low oil level Engine switch OFF Choke not set correctly Spark plug fouled | Add fuel Add oil to correct level Turn engine switch ON Adjust choke Clean or replace spark plug |
| No power output | Circuit breaker tripped Overload Faulty connection | Reset circuit breaker Reduce connected load Check all connections |
| Engine runs rough | Stale fuel Clogged air filter Spark plug issue | Drain and refill with fresh fuel Clean or replace air filter Inspect/replace spark plug |
If problems persist after attempting these solutions, contact qualified service personnel.
