SAFETY
Be Aware of the Working Environment
Avoid long-term
operation in very hot or
very cold weather.
Make sure bystanders
or observers outside the
15 meter “danger zone”
wear eye protection.
Be extremely careful of
slippery terrain, especially
during rainy weather.
Always make sure
the appropriate cutting
attachment shield is
correctly installed.
If contact is made with a hard object, stop the engine
and inspect the cutting attachment for damage.
Be constantly alert for objects and
debris that could be thrown either
from the rotating cutting attachment or
bounced from a hard surface.
Reduce the risk of bystanders being struck
by flying debris. Make sure no one is
within 15 meters — that’s about 16 paces
— of an operating attachment.
Stop immediately if a child, pet, or person
comes within a 15 meter radius.
Beware of a coasting blade when
brushcutting or edging. A coasting blade
can injure while it continues to spin after
the throttle trigger is released or after the
engine is stopped.
15
METERS
ALWAYS clear your work area of trash or
hidden debris that could be thrown back at
you or toward a bystander. When operating in
rocky terrain or near electric wires or fences,
use extreme caution to avoid contacting such
items with the cutting attachment.
The Properly Equipped Operator
Always wear a harness when operating
the unit . It adds comfort and helps ensure
safety by limiting movement fore and aft.
When the harness is adjusted properly,
the unit should balance with the cutting
attachment parallel to the ground.
Always operate with both hands firmly
gripping the unit.
Wear close-fitting clothing to
protect legs and arms. Gloves offer
added protection and are strongly
recommended. Do not wear clothing
or jewelry that could get caught in
machinery or underbrush. Secure long
hair so that it is above shoulder level.
NEVER wear shorts!
Wear hearing protection devices and a broadbrimmed hat or helmet.
A helmet is required when using a blade-equipped
brushcutter to clear small trees.
Always wear eye protection such as
goggles or safety glasses to shield
against thrown objects.
When operating with a blade, make sure the
handle is positioned to provide you with maxi-
mum protection from contacting the blade.
Always make sure the handlebar is installed in
accordance with the manufacturers instructions.
Keep away from the rotating
trimmer line or blade at all
times, and never lift a moving
attachment above waist-high.
Wear appropriate footwear (non-skid boots
or shoes): do not wear open-toed shoes or
sandals. Never work barefooted!
Keep a proper footing and do not overreach.
Maintain your balance at all times during operation.
Always make sure the appropriate cutting
attachment shield is correctly installed and
in good condition. Do not operate the unit
if the cutting attachment shield is missing,
loose, or broken.
Long-term exposure to vibration can damage
your hands.
Prolonged exposure to excessive noise is
fatiguing and could lead to impaired hearing.
Do not operate the unit if the
cutting attachment shield is
missing, loose, or broken.

Checking Unit Condition
WARNING!
A cutting attachment shield or other protective device is no guarantee of protection against ricochet. YOU MUST ALWAYS

devices (harness, ignition switch, blade
retention clip, etc.) removed!
ALWAYS make sure the cutting attachment is properly installed and firmly tight

NEVER use a cracked or warped cutting
attachment: If a properly installed attach
ment vibrates, replace the attachment with
a new one and re-check.
ALWAYS stop the engine immediately and
check for damage if you strike a foreign
object or if the unit becomes tangled. Do
not operate with broken or damaged equip
-
ment.
NEVER allow the engine to run at high
RPM without a load. Doing so could damage the engine.
NEVER operate a unit with worn or damaged fasteners or attachment holders.
NEVER cut with a dull blade. Doing so will
increase the risk of blade thrust and may
also cause equipment damage.
