6-1. BLOWER OPERATIONS
WARNING
Because of flying debris, always wear American National
Standards Institute approved shielded safety glasses or
face shield when operating blower.
WARNING
Before using your blower, review Safety Precautions in your
User Manual, and all regulations for operation of the unit.
These precautions and regulations are for your protection.
WARNING
DO NOT operate the blower with other people or animals in
the immediate vicinity. Allow a minimum of 50 feet (15
meters) between operator and other people or animals.
1. Use the blower for trees, shrubs, flower beds, and
hard-to-clean areas.
2. Use the unit around buildings and for other normal
cleaning procedures.
3. Use the blower around walls, overhangs, fences, and
screens.
4. We recommend that a face mask be worn when oper-
ating blower in dusty areas.
5. Stand away from the debris, at a distance that will
easily allow you to control the direction of blown
debris. Never blow debris in direction of bystanders.
6. To control velocity of airstream, blower can be operat-
ed at any speed between idle and full throttle.
Experience with the unit will help you determine the
amount of airflow necessary for each application.
7. Operate power equipment only at reasonable hours--
not early in the morning or late at night when people
might be disturbed. Comply with times listed in local
ordinances.
8. To reduce sound levels, limit the number of pieces of
equipment used at any one time.
9. Operate power blowers at the lowest possible throttle
speed to do the job.
10. Check your equipment before operation, especially
the muffler, air intakes and air filters.
11. Use rakes and brooms to loosen debris before blow-
ing.In dusty conditions, slightly dampen surfaces
when water is available.
12. Conserve water by using power blowers instead of
hoses for many lawn and garden applications, includ-
ing areas such as gutters, screens, patios, grills,
porches and gardens.
13. Watch out for children, pets, open windows or freshly
washed cars, and blow debris safely away.
14. Use intermediate tube plus nozzle of your choice so
the airstream can work close to the ground.
15. After using blowers and other equipment, CLEAN UP!
Dispose of debris in trash receptacles.
