 Use the tip of string to do the cutting; do not force string
head into uncut grass.
 Wire and picket fences cause extra string wear and break-
age. Stone and brick walls, curbs, and wood may wear
string rapidly.
WARNINg:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.

Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing
dust. If operation is dusty, also wear a dust mask.

Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
gENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNINg:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or de-
stroy plastic which may result in serious personal injury.

and fence posts can easily be damaged by the string.
