3. Setup and Assembly
3.1 Fuel Preparation
The GBV 322 uses a 2-stroke petrol engine. It requires a mixture of unleaded petrol and 2-stroke engine oil. Refer to the engine unit for the correct mixing ratio, typically 50:1 (petrol:oil). Always mix fuel in a separate, approved container and shake well before filling the fuel tank. Avoid spilling fuel.
3.2 Blower Mode Assembly
- Ensure the engine is off and cool.
- Attach the blower tube securely to the outlet port of the engine unit. Ensure it clicks into place or is fastened according to the mechanism (e.g., twist-lock, screw).
3.3 Vacuum/Mulcher Mode Assembly
- Ensure the engine is off and cool.
- Remove the blower tube if attached.
- Attach the vacuum tube to the intake port of the engine unit.
- Connect the collection bag to the exhaust port. Ensure all connections are tight to prevent debris leakage and maintain suction efficiency.
- Attach the shoulder strap to the designated points on the engine unit and collection bag for comfortable use.
4. Operating Instructions
4.1 Starting the Engine (Soft Start)
- Place the machine on a flat, stable surface.
- Ensure the fuel tank is filled with the correct fuel mixture.
- Set the ON/OFF switch to the "ON" position.
- Engage the choke (if cold start).
- Press the primer bulb several times until fuel is visible in the return line.
- Pull the starter cord firmly and smoothly until the engine attempts to start. The Soft Start system reduces resistance for easier pulling.
- Once the engine fires, disengage the choke.
- Allow the engine to warm up for a few moments before applying full throttle.
4.2 Blower Operation
Hold the blower firmly with both hands. Direct the blower tube towards the debris you wish to move. Use a sweeping motion to gather leaves and other light garden waste into piles. The adjustable blower speed allows for control over air velocity (up to 322 km/h).

4.3 Vacuum and Mulcher Operation
With the vacuum tube and collection bag attached, guide the vacuum tube over the debris. The machine will suck up leaves and light garden waste, which will then be mulched by internal blades before being deposited into the 45-liter collection bag. This mulching action reduces the volume of debris, allowing for longer operation before emptying the bag.

4.4 Stopping the Engine
To stop the engine, move the ON/OFF switch to the "OFF" position. Allow the engine to cool down before storing or performing any maintenance.
5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your GBV 322.
- Air Filter: Check and clean the air filter regularly, especially after prolonged use in dusty conditions. A dirty air filter can reduce engine performance.
- Spark Plug: Inspect the spark plug periodically. Clean or replace it if it is fouled or worn. Use the provided spark plug wrench.
- Collection Bag: Empty the collection bag frequently to prevent blockages and maintain vacuum efficiency. Clean the bag as needed.
- General Cleaning: Keep the machine clean from debris, especially around air intakes and cooling fins, to prevent overheating.
- Storage: When storing for extended periods, drain the fuel tank or use a fuel stabilizer. Store the machine in a dry, well-ventilated area, out of reach of children.
