Safety Precautions and

Working Techniques

Because the chain of a concrete cut‐

ter runs at very high speeds, special

safety precautions must be observed

to reduce the risk of personal injury.
It is important you read and under‐

stand the User Manual before com‐

missioning and keep it in a safe place

for future reference. Non-compliance

with the User Manual may cause seri‐

ous or even fatal injury.

Observe all applicable local safety regulations,

e.g. by trade organizations, social insurance

institutions, labor safety authorities etc.
If you have never used a power tool before:

Have your dealer or other experienced user

show you how to operate your machine – or

attend a special course to learn how to operate

it.
Minors should never be allowed to use the

machine – except for apprentices over the age of

16 when working under supervision.
Children, animals and bystanders must remain at

a distance.
When not using the machine, it must be laid

down in such a way that it does not endanger

anyone. Ensure that the machine cannot be

used without authorization.
The user is responsible for accidents or risks

involving third parties or their property.
Do not lend or rent your power tool without the

User Manual. Be sure that anyone using it under‐

stands the information contained in this manual.
The use of machines that emit noise may be limi‐

ted to certain hours of the day as specified by

national and/or regional or local regulations.
Anyone operating the machine must be well res‐

ted, in good physical health and in good mental

condition.
If you have any condition that might be aggrava‐

ted by strenuous work, check with your doctor

before operating a machine.
If you have a pacemaker: The ignition system of

your machine produces an electromagnetic field

of very low intensity. This field may interfere with

some pacemakers. STIHL recommends that per‐

sons with pacemakers consult their physician

and the pacemaker manufacturer to reduce any

health risk.

Anyone who has consumed alcohol or drugs or

medicines affecting their ability to react must not

operate a power tool.
To reduce the risk of accidents or injury, put off

the work in poor weather conditions (rain, snow,

ice, wind).
The machine may only be used for cutting.
The machine must not be used for any other pur‐

poses – risk of accidents!
It is not suitable for cutting wood or wooden

objects.
Asbestos dust is extremely toxic - the machine

must therefore never be used to cut asbestos!
Only use tools, guide bars, diamond abrasive

chains or accessories which have been

approved by STIHL for this machine or which are

technically equivalent. If you have any questions

in this respect, consult your dealer. Use only high

quality parts and accessories. in order to avoid

the risk of accidents and damage to the machine.
STIHL recommends the use of genuine STIHL

guide bars, diamond abrasive chains, chain

sprockets 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 high-pressure washer to clean the

power tool. The solid jet of water may damage

parts of the unit.

2.1

Clothing and equipment

Wear proper protective clothing and equipment.

Clothing must be sturdy but allow

complete freedom of movement.

Wear close-fitting clothes such as a

boiler suit, not a loose jacket.

Do not wear garments that could get caught in

moving parts of the machine – such as scarves,

neckties, jewelry. Tie up and confine long hair

above your shoulders.

Wear steel-toed safety boots with

non-slip soles.
