Working conditions
Operate and start your power tool only 
outdoors in a well ventilated area. 
Operate it under good visibility and 
daylight conditions only. Work carefully.
!Warning!
As soon as the engine is 
running, this product 
generates toxic exhaust 
fumes containing 
chemicals (such as 
unburned hydrocarbons 
and carbon monoxide) known to cause 
respiratory problems, cancer, birth 
defects, or other reproductive harm. 
Some of the gases (e.g. carbon 
monoxide) may be colorless and 
odorless. To reduce the risk of serious or 
fatal injury/illness from inhaling toxic 
fumes, never run the machine indoors or 
in poorly ventilated locations.
!Warning!
If the vegetation being cut or the 
surrounding ground is coated with a 
chemical substance (such as an active 
pesticide or herbicide), read and follow 
the instructions and warnings that 
accompanied the substance at issue.
!Warning!
Inhalation of certain dusts, especially 
organic dusts such as mold or pollen, 
can cause susceptible persons to have 
an allergic or asthmatic reaction. 
Substantial or repeated inhalation of 
dust and other airborne contaminants, in 
particular those with a smaller particle 
size, may cause respiratory or other 
illnesses. Control dust at the source 
where possible. Use good work 
practices, such as operating the unit so 
that the wind or operating process 
directs any dust raised by the power tool 
away from the operator. Follow the 
recommendations of EPA/OSHA/
NIOSH and occupational and trade 
associations with respect to dust 
(“particulate matter”). When the 
inhalation of dust cannot be substantially 
controlled, i.e., kept at or near the 
ambient (background) level, the 
operator and any bystanders should 
wear a respirator approved by NIOSH/
MSHA for the type of dust encountered.
Operating instructions
!Warning!
Do not operate your power tool using the 
starting throttle lock, as you do not have 
control of the engine speed.
In the event of an emergency, switch off 
the engine immediately – move the slide 
control / stop switch to 0 or STOP.
!Warning
The cutter blades continue to move for a 
short period after the throttle trigger is 
released (flywheel effect).
Accelerating the engine while the blades 
are blocked increases the load and will 
cause the clutch to slip continuously. 
This may result in overheating and 
damage to important components (e.g. 
clutch, polymer housing components) – 
which can then increase the risk of injury 
from the blades moving while the engine 
is idling.
!Warning!
Before you start work, examine the 
hedge area for stones, fence wire, metal 
or other solid objects which could 
damage the cutter blades.
