you have any health condition that may be 
aggravated by strenuous work.

of any substance (drug, alcohol or medication, etc.) 
that might impair vision, balance, dexterity or 
judgment.

tired. Take a break if you become tired.

5.4 Personal Protective Equipment
WARNING
■ Even a properly installed and adjusted deflector may not 
protect the operator from all foreign objects thrown back 
by the cutting attachment. Thrown objects may also 
ricochet and strike the operator. To reduce the risk of 
personal injury:
– Always wear proper clothing and protective apparel, 
including proper eye protection.
■ Loss of control and severe cut injuries may result if hair, 
clothing or apparel make contact with the moving cutting 
attachment or otherwise become entangled in the 
components of the trimmer. To reduce the risk of severe 
personal injury:
– Avoid loose-fitting jackets, scarves, neckties, flared 
or cuffed pants, jewelry and any other apparel that 
could be caught on branches, brush or the moving 
cutting attachment.
– Secure hair above shoulder level before starting 
work.
■ To reduce the risk of eye injury:
– If there is a risk of facial injury, STIHL recommends 
that you also wear a face shield or face screen over 
your goggles or protective glasses.
– Wear an approved protective helmet, when there is 
a risk of head injury.
■ Good footing is very important. To help maintain a secure 
footing and reduce the risk of injury while working:
■ To improve your grip and help protect your hands:
– Wear sturdy and snug-fitting clothing that 
also allows complete freedom of 
movement.
– Wear overalls or long pants made of 
heavy material to help protect your legs. 
Do not wear shorts.
– Always wear goggles or close-fitting 
protective glasses with adequate side 
protection that are impact-rated and 
marked as complying with CSAZ94.

soles. Do not wear sandals, flip-flops, 
open-toed or similar footwear.

gloves made of leather or another wear-
resistant material when handling the 
trimmer or its cutting attachment.
