5.6.4 Operating Instructions
WARNING
■ In the event of an emergency:
– Switch off the motor immediately and remove the
battery.
■ The blower fan between the air intake and output opening
rotates whenever the motor is running. To reduce the risk
of injury from contact with the blower fan:
– Never operate the blower with a missing, cracked or
worn intake screen or housing.
– Never operate the blower without a properly
mounted blower tube and nozzle.
– Keep hair, loose clothing, fingers and all parts of the
body away from openings and moving parts of the
blower.
■ The air flow from the blower can propel small objects at
high speed. To reduce the risk of eye or other serious
personal injuries to bystanders from blown objects:
– Keep bystanders and pets at least 16 ft. (5 m) away
when the blower is running.
– Never direct the air flow toward bystanders or pets.
– Do not allow the blower to be used as a toy.
– Switch off the blower immediately if you are
approached.
■ A missing, cracked or worn intake screen or housing may
result in an increased risk of injury from thrown objects.
– Never operate a blower that has a missing, cracked
or worn intake screen or housing.
■ Inserting any foreign object into the air intake or nozzle
may result in property damage, including damage to the
blower itself, and serious injury to the operator or
bystanders as a result of the object or broken parts being
blown at high speed.
– Never insert any objects into the nozzle or air intake
of the blower.
– Immediately switch off the blower if it starts to vibrate
abnormally.
■ Using the blower to spread herbicides, pesticides,
fertilizers or other chemical substances can be dangerous
and may cause serious or fatal injury to persons and
damage to the environment.
– Never use the blower to disperse or spread
chemicals of any kind.
