During Operation
Holding and Controlling the Power Tool
Always hold the unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
around the handles, keeping the
handles cradled between your thumb
and forefinger. Keep your hands in this
position to have your power tool under
control at all times.
Warning!
To reduce the risk of injury from loss of
control, never work on a ladder or on
any other insecure support.
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 gen-
erates toxic exhaust
fumes containing chemi-
cals, such as unburned
hydrocarbons (including
benzene) and carbon monoxide, that
are known to cause respiratory prob-
lems, cancer, birth defects, or other
reproductive harm. Some of the gases
(e.g. carbon monoxide) may be color-
less and odorless. To reduce the risk of
serious or fatal injury / illness from inhal-
ing toxic fumes, never run the machine
indoors or in poorly ventilated locations.
Warning!
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction. Sub-
stantial or repeated inhalation of dust
and other airborne contaminants, in par-
ticular those with a smaller particle size,
may cause respiratory or other ill-
nesses. Control dust at the source
where possible. Use good work prac-
tices, 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 recom-
mendations of EPA / OSHA / NIOSH
and occupational and trade associa-
tions with respect to dust ("particulate
matter"). When the inhalation of dust
cannot be substantially controlled, i.e.,
kept at or near the ambient (back-
ground) 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.
