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.
◆ Use rakes and brooms to loosen debris before blowing.
◆ In dusty conditions, slightly dampen surfaces when water 
is available.
◆ Conserve water by using blowers instead of hoses for 
many lawn and garden applications, including areas such 
as gutters, screens, patios, grills, porches, and gardens.
◆ Use the full blower nozzle extension when blowing.
◆ After using blowers and other equipment, CLEAN UP! 
Dispose of debris in trash receptacles.
To avoid engine damage due to over-revving, do not block blower 
pipe.
1. Use only during appropriate hours.
2. To reduce sound levels, limit the number of pieces of equipment used at 
any one time.
3. Allow the engine to warm up at a fast idle for a few minutes.
