FT 250

Always stand on the ground while 

working, never on a ladder, work 

platform 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.
To reduce the risk of accidents, take a 

break in good time to avoid tiredness or 

exhaustion.
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 serious or fatal 

injury from breathing toxic fumes, 

ensure proper ventilation when working 

in trenches, hollows or other confined 

locations.
To reduce the risk of accidents, stop 

work immediately in the event of 

nausea, headache, visual disturbances 

(e.g. reduced field of vision), problems 

with hearing, dizziness, deterioration in 

ability to concentrate. Apart from other 

possibilities, these symptoms may be 

caused by an excessively high 

concentration of exhaust gases in the 

work area.
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.
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.
The dusts, vapor and smoke produced 

during operation may be dangerous to 

health. If the work area is very dusty or 

smoky, wear a respirator.
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".
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.
Do not operate your power tool in the 

starting throttle position – engine speed 

cannot be controlled in this position.

Special care must be taken when 

working in difficult, over-grown terrain.
When cutting high scrub, under bushes 

and hedges: Keep cutting attachment at 

a minimum height of 15 cm to avoid 

harming small animals.
Before leaving the power tool 

unattended: Shut off the engine.
Check the cutting attachment at regular 

short intervals during operation or 

immediately if there is a noticeable 

change in cutting behavior:

Turn off the engine. Hold the unit 

firmly and wait for the cutting 

attachment to come to a standstill.

Check condition and tightness, look 

for cracks.

Check sharpness.

Replace damaged or dull cutting 

attachments immediately, even if 

they have only superficial cracks.

Clean grass and plant residue off the 

cutting attachment mounting at regular 

intervals – remove any build up of 

material from the cutting attachment and 

deflector.
To reduce the risk of injury, shut off the 

engine before changing the cutting 

attachment.

Your power tool produces 

toxic exhaust fumes as 

soon as the engine is 

running. These fumes 

may be colorless and 

odorless and contain 

unburned hydrocarbons 

and benzol. Never run 

the engine indoors or in 

poorly ventilated loca

-

tions, even if your model 

is equipped with a cata

-

lytic converter.

To reduce the risk 

of injury from 

thrown objects, 

never operate the 

unit without the 

proper deflector for 

the type of cutting 

attachment being 

used.

Inspect the work area: 

Stones, pieces of metal 

or other solid objects may 

be thrown more than 15 

meters and cause per

-

sonal injury or damage 

the cutting attachment 

and property (e.g. parked 

vehicles, windows).
