SAFETY WARNINGS

Do not wear loose fitting clothing or articles

such as scarves, strings, chains, ties, etc.,
because they could get caught in moving
parts. Also make sure long hair does not get
caught in moving parts. Long hair must be
pulled back and secured off shoulders and
neck.

• Keep hands, face, and feet away from all 

moving parts. Do not attempt to touch or 
stop the string when it is rotating.

• Always hold the trimmer with both hands 

when operating. Keep a firm grip on both 
the front and rear handles or grips.

• Frequently inspect the condition of the

cutting head. All damaged parts must be
replaced immediately. Follow all the required
precautions when undertaking replacement.

• If you strike or become entangled with a 

foreign object, stop the engine immediately 
and check for damage. Repair any damage 
before further operation is attempted. Do 
not operate the trimmer with loose or 
damaged parts.

• Do not operate the unit faster than the speed

necessary to cut, trim or edge. Do not run
the unit at high speed when not cutting.

• Do not force the unit. It will do the job better

and with less likelihood of a risk of injury at
the rate for which it was designed.

• The string guard must be in place at all 

times while operating the trimmer. Failure 
to use the string guard may cause the unit 
to overheat. DO NOT OPERATE WITHOUT
THE GUARD IN PLACE.

• Do not extend the trimming line beyond the

length of the guard specified in this manual.

• Do not operate trimmer without both

trimming lines extended, and the proper 
line installed.

• Never use metal-reinforced or monofilament

line that is not specifically designed for use
with your model.

• Keep trimmer clean of vegetation and other

materials.

• Always stop the unit when cutting is delayed

or when walking from one cutting location 
to another.

• All interventions, whether for maintenance,

repair or for changing cutting head or safety
attachments, must be undertaken with the
unit disconnected from the power supply.

• Use only genuine replacement parts when 

servicing this trimmer. These parts are 
available from your authorized dealer.
The use of non-standard parts, or other
accessories or attachments not designed for
this trimmer, could result in serious injury to
the user or damage to the trimmer and void
your warranty.
