The Properly Equipped Operator
Wear hearing protection devices and a
broad-brimmed hat or helmet. A helmet
is required when using a blade-equipped
brushcutter to clear small trees.
Prolonged exposure to excessive noise
is fatiguing and could lead to impaired
hearing.
Wear close-tting 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!
Long-term exposure to vibration
can damage your hands.
Keep a proper footing and do not
overreach. Maintain your balance at all
times during operation.
Always wear eye protection such as
goggles or safety glasses to shield
against thrown objects.
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
rmly gripping the unit.
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.
Wear appropriate footwear (non-skid
boots or shoes): do not wear opentoed shoes or sandals. Never work
barefooted!

operation in very hot
or very cold weather.
Be extremely careful
of slippery terrain,
especially during rainy
weather.
Be constantly alert for
objects and debris that
could be thrown either
from the rotating cutting
attachment or bounced
from a hard surface.
If contact is made with a hard object,
stop the engine and inspect the cutting

(50 feet)radius. Outside this radius,
there is still a risk of injury from thrown
objects.
Do not operate the unit
if the cutting attachment
shield is missing, loose,
or broken.
ALWAYS clear your work area of trash
or hidden debris that could be thrown
back at you or toward a bystander.

WARNING!
A standard grass trimmer with a loop handle should NEVER be
operated with blade-type attachments. For blade use the trimmer must be
tted with a bicycle-type handlebar or a barrier bar that is located in front of
the operator to reduce the risk of the operator from coming in contact with
the cutting attachment (per ANSI B175.3). When using a blade, the unit must
also be equipped with a harness or strap.
The unit should now be
completely assembled and
ready for use with a trimmer
head.
