5 General Power Tool Safety Warnings

5.1 Introduction

This chapter contains the prescribed general safety 

warnings and instructions for handheld, motor-operated 

electric power tools and motor-operated electric chain saws. 

Additional important warnings and instructions are provided 

in subsequent chapters of this manual.

WARNING

■ Read all safety warnings and all instructions. Failure to 

follow the warnings and instructions may result in electric 

shock, fire and/or serious injury.

■ Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-

operated (corded) power tool or battery-operated (cordless) 

power tool.

5.2 Work Area Safety

a)Keep work area clean and well lit. Cluttered or dark areas 

invite accidents.

b)Do not operate power tools in explosive atmospheres, 

such as in the presence of flammable liquids, gases or 

dust. Power tools create sparks which may ignite the dust 

or fumes.

c) Keep children and bystanders away while operating a 

power tool. Distractions can cause you to lose control.

5.3 Electrical Safety

a)Power tool plugs must match the outlet. Never modify the 

plug in any way. Do not use any adapter plugs with 

earthed (grounded) power tools. Unmodified plugs and 

matching outlets will reduce the risk of electric shock.

b)Avoid body contact with earthed or grounded surfaces, 

such as pipes, radiators, ranges and refrigerators. There 

is an increased risk of electric shock if your body is 

earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water 

entering a power tool will increase the risk of electric 

shock.

d)Do not abuse the cord. Never use the cord for carrying, 

pulling or unplugging the power tool. Keep cord away from 

heat, oil, sharp edges or moving parts. Damaged or 

entangled cords increase the risk of electric shock.

e)When operating a power tool outdoors, use an extension 

cord suitable for outdoor use. Use of a cord suitable for 

outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location is 

unavoidable, use a residual current device (RCD) 

protected supply. Use of an RCD reduces the risk of 

electric shock.

5.4 Personal Safety

a)Stay alert, watch what you are doing and use common 

sense when operating a power tool. Do not use a power 

tool while you are tired or under the influence of drugs, 

alcohol or medication. A moment of inattention while 

operating power tools may result in serious personal 

injury.

b)Use personal protective equipment. Always wear eye 

protection. Protective equipment such as dust mask, non-

skid safety shoes, hard hat, or hearing protection used for 

appropriate conditions will reduce personal injuries. 

To reduce the risk of injury or property damage, 

immediately disconnect the chain saw from the 

power supply if the power supply cord or the 

extension cord is damaged, 

@

6.6.

To reduce the risk of electric shock, do not 

expose the chain saw to rain, water or excessive 

moisture. Store it indoors. If it is exposed to rain 

or very damp conditions, take it to your 

authorized STIHL servicing dealer before further 

operation,
