Work Safely

Trimmers and brushcutters operate at very
high speeds and can do serious damage or
injury if they are misused or abused. Never

allow a person without training or instruc­tion to operate this unit!

WARNING!

Use Good Judgment

NEVER run the engine when trans­porting the unit.
NEVER run the engine indoors! Make
sure there is always good ventila­tion. Fumes from engine exhaust can
cause serious injury or death.
ALWAYS use the proper cutting tool
for the job.
ALWAYS stop the unit immediately if
it suddenly begins to vibrate or shake.
Inspect for broken, missing or improp­erly installed parts or attachments.
NEVER extend trimming line beyond

the length specied for your unit.

ALWAYS keep the unit as clean as
practical. Keep it free of loose vegeta­tion, mud, etc.

ALWAYS hold the unit rmly with both

hands when cutting or trimming, and
maintain control at all times.

ALWAYS keep the handles clean.
ALWAYS disconnect the spark plug

wire before performing any
maintenance work.
ALWAYS, if a saw blade should bind
fast in a cut, shut off the engine im­mediately. Push the branch or tree to
ease the bind and free the blade.

SAFETY

Be Aware of the Working Environment

Avoid long-term opera-

tion 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 slip-

pery 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 ying debris. Make

sure no one is within 15 meters

— that’s about 16 paces — of an

operating attachment.

Beware of a coasting blade when brushcut-

ting 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

a unit equipped with a blade.

Always operate with both hands rmly grip-

ping the unit.

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!

Wear hearing protection devices and a

broad-brimmed hat or helmet.

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.

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 open­toed 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.

Checking Unit Condition

WARNING!

A cutting attachment shield or other protective device is no guarantee of protection against ricochet. YOU MUST ALWAYS
GUARD AGAINST FLYING DEBRIS!

Use only authorized Shindaiwa parts and accessories with your
Shindaiwa trimmer or brushcutter. Do not make modifications to
this unit without the written approval of Shindaiwa, Inc.

NEVER operate the unit with the cutting attachment shield or
other protective devices (harness, ignition switch, blade retention
clip, etc.) removed!

ALWAYS make sure the cutting attachment is properly installed
and firmly tightened before operation.

NEVER use a cracked or warped cutting attachment: If a properly
installed attachment 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 equipment.

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.
