HOLDING THE BLOWER
Before operating the unit, stand in the operating position (Fig. 21).
Check for the following:
• Operator is wearing proper clothing, such as boots, safety
glasses or goggles, ear/hearing protection, gloves, long pants
and long sleeve shirt.
• If the conditions are dusty, the operator is wearing a dust mask
or face mask.
WARNING:
To avoid serious personal injury, wear
goggles or safety glasses at all times when operating
this unit. Wear a face mask or dust mask in dusty
locations.
• The unit is in good working condition.
• The tubes are in place and secure.
OPERATING TIPS
• Assure the unit is not directed at anybody or any loose debris
before starting the unit.
• Verify that the unit is in good working condition. Make sure the
tubes are in place and secure.
• Always hold the unit securely when operating.
• To reduce the risk of hearing loss associated with sound level(s),
hearing protection is required.
• 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. Usual recommendations are 9:00
am to 5:00 pm, Monday through Saturday.
• To reduce noise levels, limit the number of pieces of equipment
used at any one time.
• To reduce noise levels, operate power blowers at the lowest
possible speed to do the job.
• Check your equipment before operation, especially the muffler,
air intakes and air filters.
• Use rakes and brooms to loosen debris before blowing.
• In dusty conditions, slightly dampen surfaces or use a mister
attachment when water is available.
• Conserve water by using power blowers instead of hoses for
many lawn and garden applications, including areas such as
screens, patios, grills, porches, and gardens.
• Watch out for children, pets, open windows or freshly washed
cars, and blow debris safely away.
• Use the full blower nozzle extension so the air stream can work
close to the ground.
• Clean up after using blowers and other equipment. Dispose of
debris appropriately.
• Use the trigger lock (Fig. 16) to keep the trigger depressed while
operating to make continuous operation easier.
