How can we help?

If you’re having difficulties starting your RYOBI Petrol Blower Vacuum or if it’s running roughly, try the following troubleshooting steps:

Follow the correct starting process:

1. Before starting the Blower Vacuum, attach the Blower tube first.
2. Press the primer bulb 10 times.
3. Pull the choke out to full.
4. Pull the starter cord until the engine sounds like it is about to start but no more than 5 times.
5. Push the choke in to half.
6. Pull the starter cord until the unit starts.
7. Squeeze and release the trigger a few times.
8. Let the unit sit on idle for 15-30 seconds before use.

Flooded Engine

• A flooded engine can cause a Blower Vacuum not to start.
• A flooded engine means there is excessive fuel pumped into the engine which has displaced the oxygen needed to start the Blower Vacuum.
• If you’ve attempted to start the engine unsuccessfully there is a chance your engine is flooded.
• Let your blower vacuum sit for 15-20 minutes before starting it again following the correct starting procedure.

Stale Fuel

• A common cause is stale fuel as fuel starts to lose its volatility after 30 days - this will affect the ignition of an engine.
• Replace your fuel with some fresh fuel and see if this helps.
• You can also buy fuel stabiliser that will keep fuel fresh for 12 months. You can purchase this from your local Bunnings store. 

Dirty air filter/spark plug

• Another common cause of a hard to start motor or a roughly running motor is a dirty air filter or spark plug.
• These parts should be inspected regularly and do require replacement throughout the life of a Blower Vacuum.
• To find and order the correct replacement filters and spark plugs for your unit please contact your local Bunnings Special Orders desk and quote them your Blower Vacuum model number.

Incorrect fuel mixture

• Incorrect fuel mixture can cause the Blower Vacuum to not start or run, make sure you are using the correct fuel mixture with your Blower Vacuum.
• RYOBI Blower Vacuums run off a 50:1 ratio - this means 50 parts unleaded fuel to 1 part 2-stroke oil.

​​​​​​​

Choke left on

• The choke being left on can cause your RYOBI Blower Vacuum to not run correctly and shut off.
• Once your Blower Vacuum has started, make sure it’s in the run position.
• Make sure to follow the correct blower vacuum starting procedure.

Spark plug lead disconnected

• The spark plug lead can sometimes disconnect
• Make sure the spark plug lead is connected properly.
