During Operation
Holding and Controlling the Power Tool
The blower is designed for single-
handed operation with the right hand on
the control handle. It should be carried
as a backpack with the straps of the
harness over both shoulders.
Watch out for small animals when using
the blower on open ground, in yards and
gardens.
WARNING
To reduce the risk of loss of control,
never carry the unit with the strap(s)
over one shoulder.
Wrap your fingers tightly around the
handle, keeping the control handle
cradled between your thumb and
forefinger. Keep your hand in this
position to have your machine under
control at all times.
WARNING
Special care must be taken in slippery
conditions (wet ground) and in difficult,
overgrown terrain. Watch for hidden
obstacles such as tree stumps, roots,
rocks, holes and ditches to avoid
stumbling. For better footing, clear away
fallen branches, scrub and cuttings. Be
extremely cautious when working on
slopes or uneven ground.
To reduce the risk of stumbling and loss
of control, do not walk backward while
operating the machine.
WARNING
To reduce the risk of injury from loss of
control, never work on a ladder or on any
other insecure support.
Working Conditions
To minimize blowing time, use a rake
and broom to loosen dirt particles before
you start blowing.
Save water by using a blower instead of
a water hose for lawn and garden work
wherever possible, e.g. for cleaning
yards and patios.
Recommended working technique to
minimize air pollution:
– If conditions are very dusty, dampen
surfaces slightly before blowing.
– Pull out the nozzle to full length so
that the airstream is at ground level.
– Do not blow particles in the direction
of bystanders, in particular in the
direction of children, pets, open
windows or freshly washed
vehicles. Take special care in such
situations.
– Remove the blow-swept debris in
rubbish bins – do not blow it onto the
neighbor's land.
Recommended working technique to
minimize noise:
– Operate your power tool at
reasonable times only – not early in
the morning, late at night or during
midday rest periods when people
could be disturbed. Observe local
rest periods. Normal
recommendation for professional
use on weekdays: 9:00hrs to
12:00hrs and 15:00hrs to 17:00hrs.
Be considerate of neighbors at
weekends.
– Fewer engines mean less noise.
Where possible, do not run more
than one power tool at any time.
– Operate blowers at the lowest
engine speed necessary to
accomplish the task.
– Check your blower before starting
work. Pay special attention to the
muffler, air intakes and air filter.
Operate and start your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
