Never work on a ladder or any other insecure

support.
Be particularly alert and cautious when wearing

hearing protection because your ability to hear

warnings (shouts, alarms, etc.) is restricted.
Work calmly and carefully – in daylight conditions

and only when visibility is good. Stay alert so as

not to endanger others.
To reduce the risk of accidents, take a break in

good time to avoid tiredness or exhaustion.

Your power tool produces toxic

exhaust fumes as soon as the engine

is running. These fumes may be col‐

orless and odorless and contain

unburned hydrocarbons and benzol.

Never run the engine indoors or in

poorly ventilated locations, even if

your model is equipped with a cata‐

lytic converter.

To reduce the risk of serious or fatal injury from

breathing toxic fumes, ensure proper ventilation

when working in trenches, hollows or other con‐

fined locations.
To reduce the risk of accidents, stop work imme‐

diately in the event of nausea, headache, visual

disturbances (e.g. reduced field of vision), prob‐

lems with hearing, dizziness, deterioration in abil‐

ity to concentrate. Apart from other possibilities,

these symptoms may be caused by an exces‐

sively high concentration of exhaust gases in the

work area.
To reduce the risk of fire, do not smoke while

operating or standing near your power tool. Note

that combustible fuel vapor may escape from the

fuel system.
If dust levels are very high, always wear a suita‐

ble respirator.
Operate your power tool so that it produces a

minimum of noise and emissions – do not run the

engine unnecessarily, accelerate the engine only

when working.
After finishing work, put the unit down on a level,

non-flammable surface. To reduce the risk of fire,

do not put it down near easily combustible mate‐

rials (e.g. wood chips, bark, dry grass, fuel).
If your power tool is subjected to unusually high

loads for which it was not designed (e.g. heavy

impact or a fall), always check that it is in good

condition before continuing work – see also

"Before Starting Work". Check the fuel system in

particular for leaks and make sure the safety

devices are working properly. Do not continue

operating your power tool if it is damaged. In

case of doubt, consult your servicing dealer.

Using the Blower

0009BA001 KN

The machine is carried as a backpack. Hold and

control the blower tube with your right hand on

the control handle.
Walk slowly forwards as you work – observe the

nozzle outlet at all times – do not walk back‐

wards – risk of stumbling.
Always shut off the engine before taking the

machine off your back.

2.11

Working Technique

To minimize blowing time, use a rake and broom

to loosen dirt particles before you start blowing.

If necessary, dampen the surface to be

cleaned in order to avoid creating too much

dust.

Do not blow particles in the direction of

bystanders, in particular in the direction of chil‐

dren, 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.

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.

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.

2.12

Vibrations

Prolonged use of the power tool may result in

vibration-induced circulation problems in the

hands (whitefinger disease).
No general recommendation can be given for the

length of usage because it depends on several

factors.
