Do not lend or rent your power tool 
without the instruction manual. Be sure 
that anyone using it understands the 
information contained in this manual.
The use of noise emitting power tools 
may be restricted to certain times by 
national or local regulations.
To operate the power tool you must be 
rested, in good physical condition and 
mental health.
If you have any condition that might be 
aggravated by strenuous work, check 
with your doctor before operating a 
power tool.
Persons with pacemakers only: The 
ignition system of your power tool 
produces an electromagnetic field of a 
very low intensity. This field may 
interfere with some pacemakers. STIHL 
recommends that persons with 
pacemakers consult their physician and 
the pacemaker manufacturer to reduce 
any health risk.
Do not operate the power tool if you are 
under the influence of any substance 
(drugs, alcohol) which might impair 
vision, dexterity or judgment.
Depending on the cutting attachment 
fitted, use your power tool only for 
cutting grass, wild growth, shrubs, 
scrub, bushes, small diameter trees and 
similar materials.
Do not use your power tool for any other 
purpose because of the increased risk of 
accidents.
Only use cutting attachments and 
accessories that are explicitly approved 
for this power tool model by STIHL or 
are technically identical. If you have any 
questions in this respect, consult a 
servicing dealer. Use only high quality 
tools and accessories in order to avoid 
the risk of accidents and damage to the 
machine.
STIHL recommends the use of genuine 
STIHL tools and accessories. They are 
specifically designed to match the 
product and meet your performance 
requirements.
Never attempt to modify your power tool 
in any way since this may increase the 
risk of personal injury. STIHL excludes 
all liability for personal injury and 
damage to property caused while using 
unauthorized attachments.
Do not use a pressure washer to clean 
the unit. The solid jet of water may 
damage parts of the unit.
The deflector on this power tool cannot 
protect the operator from all objects 
thrown by the cutting attachment 
(stones, glass, wire, etc.). Such objects 
may ricochet and then hit the operator.
Clothing and Equipment
Wear proper protective clothing and 
equipment.
Sturdy shoes with non-slip soles may be 
worn as an alternative only when using 
mowing heads.
WARNING
Wear a face shield and make sure it is a 
good fit. A face shield alone does not 
provide adequate eye protection.
Wear hearing protection, e.g. earplugs 
or ear muffs.
Wear a safety hard hat for thinning 
operations, when working in high scrub 
and where there is a danger of head 
injuries from falling objects.
Clothing must be sturdy 
but allow complete free-
dom of movement. Wear 
snug-fitting clothing, an 
overall and jacket combi-
nation, do not wear a 
work coat.
Avoid clothing that could 
get caught on branches 
or brush or moving parts 
of the machine. Do not 
wear a scarf, necktie or 
jewelry. Tie up and con-
fine long hair (e.g. with a 
hair net, cap, hard hat, 
etc.).
Wear steel-toed safety 
boots with non-slip soles.
To reduce the risk of eye 
injuries, wear snug-fitting 
safety glasses in accord-
ance with European 
Standard EN 166. Make 
sure the safety glasses 
are a good fit.
Wear heavy-duty work 
gloves made of durable 
material (e.g. leather).
