Have your STIHL dealer show you how 
to operate your power tool. Observe all 
applicable local safety regulations, 
standards and ordinances.

Use your power tool only for the 
applications described in the instruction 
manual of the KombiTool you are using.

Most of these safety precautions and 
warnings apply to the use of all STIHL 
power tools. Different models may have 
different parts and controls. See the 
appropriate section of your 
KombiEngine and KombiTool instruction 
manuals for a description of the controls 
and the function of the parts of your 
model.

Do not clean your machine with a 
pressure washer. The solid jet of water 
may damage parts of the machine.

Safe use of a KombiEngine involves

1.

the operator

2.

the power tool

3.

the use of the power tool

THE OPERATOR

Physical Condition

You must be in good physical condition 
and mental health and not under the 
influence of any substance (drugs, 
alcohol, etc.) which might impair vision, 
dexterity or judgment. Do not operate 
this machine when you are fatigued.

These conditions reduce the hand's 
ability to feel and regulate temperature, 
produce numbness and burning 
sensations and may cause nerve and 
circulation damage and tissue necrosis.

All factors which contribute to 
whitefinger disease are not known, but 
cold weather, smoking and diseases or 
physical conditions that affect blood 
vessels and blood transport, as well as 
high vibration levels and long periods of 
exposure to vibration are mentioned as 
factors in the development of whitefinger 

Safety Precautions and 

Working Techniques

Because this KombiEn-
gine is the engine for a 
high-speed power tool, 
special safety precau-
tions must be observed to 
reduce the risk of per-
sonal injury.

It is important that you 
read, fully understand 
and observe the following 
safety precautions and 
warnings. Read the 
instruction manuals and 
the safety precautions of 
your KombiEngine and 
KombiTool periodically. 
Careless or improper use 
may cause serious or 
fatal injury.

Warning!

Do not lend or rent your power tool with-
out the instruction manuals. Be sure that 
anyone using it understands the infor-
mation contained in these manuals.

Warning!

Do not use it for other purposes, since 
misuse may result in personal injury or 
property damage, including damage to 
the machine.

Warning!

Minors should never be allowed to use 
this power tool. Bystanders, especially 
children, and animals should not be 
allowed in the area where it is in use.

Warning!

To reduce the risk of injury to bystand-
ers and damage to property, never let 
your power tool run unattended. When it 
is not in use (e.g. during a work break), 
shut it off and make sure that unauthor-
ized persons do not use it.

Warning!

Be alert – if you get tired, take a break. 
Tiredness may result in loss of control. 
Working with any power tool can be 
strenuous. If you have any condition 
that might be aggravated by strenuous 
work, check with your doctor before 
operating this machine.

Warning!

Prolonged use of a power tool (or other 
machines) exposing the operator to 
vibrations may produce whitefinger dis-
ease (Raynaud's phenomenon) or 
carpal tunnel syndrome.
