NEVER operate the unit with the cut-

ting attachment shield or other protective

devices removed!

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.

Edging

Tilt the handle about

100° to the left

(from horizontal)

tions and/or operational requirements.

CAUTION!
Operation of trimmer without a cutting at-

tachment shield and using excessive line

length can lead to premature clutch failure.

Do not make modifications to this unit with-

out written approval from Shindaiwa, Inc.
ALWAYS make sure the cutting attachment

is properly installed and firmly tightened

before operation.
NEVER use a cracked or warped cutting at-

tachment: replace it with a serviceable one.
ALWAYS make sure the cutting attachment

fits properly into the appropriate attachment

holder. If a properly installed attachment

vibrates, replace the attachment with 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 dam-

age the engine.
NEVER operate a unit with worn or dam-

aged fasteners or attachment holders.

WARNING!

Always wear a shoulder strap or

harness when operating this unit. Using

a harness with a brushcutter allows you

to maintain proper control of the unit and

reduces fatigue during extended operation.

IMPORTANT!

Adjust the shoulder strap so the shoulder pad

rests comfortably on the off-side shoulder and

the cutting path of the cutting attachment

is parallel to the ground. Make sure all

hooks and adjustment devices are secure.

Double Shoulder Harness

(optional accessory)

Adjust the double shoulder harness straps

so the shoulder pads rest comfortably on

the shoulders and the cutting path of the

blade is parallel to the ground. Make sure

all hooks and adjusting devices are secure.

angled slightly into the area to be cut. To

ensure maximum trimmer-line service life,

cut only with the tip of the trimmer line.

Cut grass by swinging the trimmer from

left to right. Keep the trimmer head hori-

zontal. See Figure 4.
