While working

In the event of impending danger or in an emer‐

gency, shut off the engine immediately – move

the stop switch / slide control in the direction of 0.
Ensure that there is nobody within a 5 m radius –

risk of injury due to falling objects This distance

must also be maintained in relation to objects

(vehicles, window panes) – risk of property dam‐

age!
Make sure the idle speed setting is correct. The

rakes and tines must not move when the engine

is idling with the throttle trigger released.
Check and correct the idle speed setting at regu‐

lar intervals. If the rakes and tines still run when

the engine is idling, have your dealer check your

machine and make proper adjustments or

repairs.
Exercise caution in wet conditions on slopes,

uneven ground, etc. – risk of slipping!
Clear away fallen branches and scrub.
Watch out for obstacles: tree stumps, roots – risk

of tripping or stumbling!

Make sure you always have good balance and

secure footing.
When working at heights:

Always use a lift bucket

Never work on a ladder

Never work in a tree

Never work in unsteady locations

Never work with just one hand

Greater care and attention than usual are

required when wearing ear protection, as sounds

(shouts, beeps, etc.), warning you of impending

danger, cannot be heard properly.
Take breaks when you start getting tired or feel‐

ing fatigue – risk of accidents!
Work calmly and carefully – in daylight conditions

and only when visibility is good. Proceed with

caution, do not put others in danger.

As soon as the engine is running, the

power machine generates toxic

exhaust gas. These gases may be

odorless and invisible. Never run the

engine indoors or in poorly ventilated

locations, even if your model is equip‐

ped with a catalytic converter.

To reduce the risk of fire, do not smoke while

operating or standing near your power tool. Com‐

bustible fuel vapor may escape from the fuel sys‐

tem.
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 in particular that the fuel

system has no leaks and the safety equipment is

fully operative. Never use a power tool that is no

longer safe to operate. In case of doubt, contact

a dealer.
Do not operate your power tool in the starting

throttle position – engine speed cannot be con‐

trolled in this position.
Before you leave the machine: Shut the engine

off.
If rakes and tines are blocked: Release the throt‐

tle trigger – switch off the engine – unblock rakes

and tines.
Opening the throttle while the rakes and tines are

blocked increases the load and reduces engine

speed. The clutch then slips continuously and

this causes overheating and damage to impor‐

tant components (e.g. clutch, polymer housing

components) – and this can increase the risk of
