OPERATION PB-250LN
Use reduced speed only when performing light-duty tasks or to
comply with local noise regulations. Continuous low speed
operation may allow fuel/oil residue to build-up on the piston
and cause rapid build-up of carbon on the spark arrestor
screen, resulting in overheating and engine damage. To reduce
harmful build-up, run engine at wide open throttle for at least 5
minutes every hour, and inspect/clean the spark arrestor screen
after approximately 40 hours of operation.
Read the Safety Section carefully.
To avoid engine damage due to over-revving, do not block blower pipe.
1. Use only during appropriate hours.
2. Allow the engine to warm up at a fast idle for a few minutes.
3. Control engine speed with throttle trigger (F), or for continuous use, set engine speed with throttle
position lever (B). Rotate throttle position lever forward for lower speed, back for higher speed.
4. Use lower speed to blow debris from hard surfaces.
5. Additional speed may be necessary to clean debris, snow, etc. from lawns and flowerbeds.
Note: Never use a higher speed setting than necessary to perform a task. Remember, the higher the engine
speed, the louder the blower noise. Minimize dust by using blower at lower speeds. Keep debris on
your property. Be Smart - be a good neighbor.
