Echo PB-2520 Operator's Manual page 24

OPERATION
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 (A), 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.
