5 IMPORTANT SAFETY INSTRUCTIONS
■ Use of this trimmer can generate dust and other 
substances containing chemicals known to cause 
respiratory problems, cancer, birth defects and other 
reproductive harm.
– Consult governmental agencies such as ECCC, 
CCOHS and PHAC 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.
– Control dust at the source where possible.
– To the extent possible, operate the trimmer so that 
the wind or operating process directs any dust, mist 
or other particulate matter raised by the trimmer 
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 PHAC and 
rated for worksite-specific conditions. Follow the 
recommendations of governmental authorities (e.g., 
CCOHS/PHAC) and occupational and trade 
associations.
■ If the vegetation being cut or the surrounding ground is 
coated with a chemical substance, such as a pesticide or 
herbicide:
– Read and follow the instructions and warnings that 
accompanied the substance coating the vegetation 
or surrounding ground.
5.7.4 Operating Instructions
WARNING
■ In the event of an emergency:
– Switch off the motor immediately and remove the 
activation key.
■ The cutting attachment continues to rotate for a short 
period after the trigger switch is fully released. This is 
known as the "flywheel effect." To reduce the risk of 
serious personal injury from contact with the cutting 
attachment:
■ The rotating cutting attachment may fling foreign objects 
directly or by ricochet a great distance. Thrown objects, 
including broken cutting attachments, may cause serious 
or fatal injury to the operator or bystanders. To reduce the 
risk of severe personal injury:
– To reduce the risk of damage to property, also 
maintain this distance from such objects as vehicles 
and windows.
– Maintaining a minimum distance of 50 ft. (15 m) 
cannot eliminate the potential risk of personal injury 
and property damage from thrown objects.
– Wait for the cutting attachment to stop 
before walking with the trimmer or 
putting it down.
– Inspect the work area. Remove stones, 
glass, pieces of metal or other objects 
that could be thrown by the cutting 
attachment, damage the cutting 
attachment or cause damage to property 
(e.g., parked vehicles, windows).
– Always wear proper eye protection and 
keep bystanders at least 50ft. (15m) 
away from the work area. Any persons 
who must enter the restricted area must 
also wear proper eye protection.
