IMPORTANT
Use reduced speed only when performing light-duty tasks or to
comply with local noise regulations. Continuous low speed opera-
tion 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.

WARNING
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a
poison gas. Breathing CO can cause unconsciousness, serious in-
jury, or death. Exhaust can cause serious burns. ALWAYS position
unit so that exhaust is directed away from your face and body.
WARNING
Always wear safety glasses, hearing protection, a face filter mask,
and take all safety precautions, or serious personal injury may
result.
Do not point the blower pipe in the direction of people or pets.
Read the Safety Section carefully.
IMPORTANT
To avoid engine damage due to over-revving, do not block blower
pipe opening.
1. Use only during appropriate hours.
2. Allow the engine to warm up at a fast idle for a few minutes.
3. Control blower speed with Throttle Trigger (B), or for continuous
use, set engine speed with Combination Throttle Position /Stop
Switch Button (A).
4. Use lower speed to blow dry leaves from walks, patios and drives.
5. Additional speed may be necessary to clean grass and leaves from
a lawn or flower bed.
6. Higher speed may be necessary to move gravel, dirt, snow, bottles
or cans from a driveway, street, parking lot or stadium.
7. Always stop unit using stop engine procedure.
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 and by
dampening material with water/mist when necessary. Keep debris
on your property.
