6 IMPORTANT SAFETY INSTRUCTIONS

■ Use of this chain saw (including sharpening the saw 

chain) can generate dust, oil mist and other substances 

containing chemicals known to cause respiratory 

problems, cancer, birth defects and other reproductive 

harm.

– Consult governmental agencies such as EPA, 

OSHA, CARB and NIOSH and other authoritative 

sources on hazardous materials if you are unfamiliar 

with the risks associated with the particular 

substances you are cutting or with which you are 

working.

■ Inhalation of certain dusts, especially organic dusts such 

as mold or pollen, can cause susceptible persons to have 

an allergic or asthmatic reaction. Substantial or repeated 

inhalation of dust or other airborne contaminants, 

especially those with a smaller particle size, may cause 

respiratory or other illnesses. This includes wood dust, 

especially from hardwoods, but also from some softwoods 

such as Western Red Cedar.

– Control dust (such as saw dust) and mists (such as 

oil mist from chain lubrication) at the source where 

possible.

– Always work with a properly sharpened saw chain, 

which produces wood chips rather than fine dust.

– To the extent possible, operate the chain saw so that 

the wind or operating process directs any dust, mist 

or other particulate matter raised by the chain saw 

away from the operator.

– When respirable dust or other particulate matter 

cannot be kept at or near background levels, always 

wear a respirator that is approved by NIOSH and 

rated for worksite-specific conditions. Follow the 

recommendations of governmental authorities (e.g., 

OSHA/NIOSH) and occupational and trade 

associations.

■ If the vegetation being cut or the surrounding ground is 

coated with a chemical substance, such as pesticide or 

herbicide:

– Read and follow the instructions and warnings that 

accompanied the substance coating the vegetation 

or surrounding ground.

■ Breathing asbestos dust is dangerous and can cause 

severe or fatal illness, respiratory illness or cancer, 

including mesothelioma. The use and disposal of 

asbestos-containing products is strictly regulated by 

OSHA and the EPA.

– Do not use your chain saw to cut or disturb asbestos 

or asbestos-containing products.

– Stop work immediately and contact the relevant 

state and local authorities and/or EPA, your 

employer or local OSHA  representative if you have 

reason to believe that you might be disturbing 

asbestos.

■ Repeated contact with waste oil can cause skin cancer 

and its use is harmful to the environment.

– Do not use waste oil to lubricate the bar and chain of 

your STIHL chain saw.

6.5.4 Operating Instructions

WARNING

■ To reduce the risk of severe personal injuries from 

unintentional starting:

– Never touch a saw chain with your hand or any part 

of your body when the battery is inserted, even when 

the chain is not rotating.

– Avoid contacting the trigger switch lockout and 

trigger switch when grasping the rear handle of the 

chain saw.
