Starting Procedure

The PR48BT uses a 2-cycle engine, requiring a mixed gas fuel. Always use the correct fuel mixture as specified in the full manual.

1. Fill Fuel Tank: Ensure the fuel tank is filled with the proper gas-oil mixture.
2. Prime the Engine: Locate the primer bulb (often positioned in a less accessible area) and press it several times until fuel is visible.
3. Set Choke: Move the choke lever to the 'Full Choke' position.
4. Pull Starter Cord: Pull the starter cord firmly and smoothly until the engine attempts to start (usually 1-3 pulls).
5. Adjust Choke: Once the engine 'pops' or briefly starts, move the choke lever to the 'Half Choke' or 'Run' position.
6. Restart Engine: Pull the starter cord again until the engine starts and runs smoothly.
7. Warm-up: Allow the engine to warm up for 30 seconds to a minute before full operation.

Controls

The blower features a comfortable handle with integrated controls:

• Variable Speed Trigger: Allows you to control the air flow speed by varying pressure on the trigger.
• Cruise Control: A slide mechanism allows you to lock the throttle at a desired speed, reducing hand fatigue during extended use.
• On/Off Switch: A clearly marked switch to power the unit on or off.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your Poulan Pro PR48BT.

• Air Filter: The air filter is easily accessible. Regularly check and clean it by vacuuming or blowing out debris. Due to the backpack design, the air filter tends to stay cleaner than on ground-level blowers.
• Fuel System: Use fresh, properly mixed 2-cycle fuel. For seasonal storage, drain the fuel system or use a fuel stabilizer.
• Spark Plug: Inspect and clean or replace the spark plug as needed to ensure reliable starting and engine performance.
• General Cleaning: Keep the exterior of the blower clean and free of debris.

6. Troubleshooting

If you encounter issues with your Poulan Pro PR48BT, consider the following common troubleshooting steps:

• Engine Not Starting:
  • Ensure the fuel tank has the correct gas-oil mixture.
  • Verify the primer bulb has been pressed sufficiently.
  • Check the choke setting.
  • Inspect the spark plug for fouling or damage.
• Loss of Power:
  • Clean or replace the air filter.
  • Ensure the fuel mixture is correct and fresh.
• Excessive Noise/Vibration:
