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

broad-brimmed 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.

Keep away from the rotating

trimmer line 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.
