Prescription glasses may be worn under the safety goggles.
Eye protection should also be worn by persons in the risk zone which extends beyond the danger zone.
HEARING AND EAR PROTECTION
Prolonged exposure to loud noise can cause impairment or loss of hearing.

WARNING 
DANGER
IN ADDITION TO HEAD, EYE AND EAR PROTECTION WEAR PROTECTIVE CLOTHES, SAFETY GLOVES AND SHOES TO PROTECT YOUR FEET AND BODY FROM THROWN OBJECTS, AND IMPROVE YOUR FOOTING ON SLIPPERY SURFACES. DO NOT WEAR TIES, JEWELLY, OR LOOSE, DANGLING CLOTHING WHICH COULD BE CAUGHT IN THE UNIT. DO NOT WEAR OPENTOED FOOTWEAR, OR GO BARE-FOOT OR BARELEGGED. IN CERTAIN SITUATIONS, TOTAL FACE AND HEAD PROTECTION MAY BE REQUIRED. FOR HEAVY BRUSH CUTTING WITH METAL BLADE, LOGGER’S TROUSERS OR LEG CHAPS WITH PROTECTIVE INSERTS ARE ADDED CONSIDERATIONS.
a)Slide suspension point up and down the tube to find the right balance. Rotate the clamp to level the cutting attachment and shield. Lock in position. If the suspension point is a free-spinning type, the unit may tend to roll over sideways, however, you should still level the attachment and shield on the front-to-rear axis.
b)Balancing and levelling, as above, may require relocation of the clamp and readjustment of the harness straps. Also, each type of cutting attachment and shield mounted on the unit may require balancing.
PREPARATION
Use a shoulder harness when provided or when recommended in this manual. Adjust both harness and the suspension point on the unit so the unit hangs with the cutting attachment a few centimetres above ground level. The cutting attachment and shield should be level in all directions. Harness the unit on the right side as shown.
NOTE
A person’s size can affect the balancing adjustment. Also the balancing procedure may not work with some ECHO units on some persons. If the procedure does not work for you, please ask your ECHO servicing dealer for assistance.
WARNING 
DANGER
ECHO TRIMMERS AND BRUSHCUTTERS ARE DESIGNED TO FIT A WIDE VARIETY OF BODY SIZES, BUT MAY NOT BE ADJUSTABLE FOR EXTREMELY TALL PERSONS.

Do not run the engine indoors, or where there is poor ventilation.
GENERAL OPERATION
Engine fumes contain deadly poisonous carbon monoxide.
Do not operate with a worn or damaged cutting attachment.
Do not run engine at full throttle without a load.
Do not hit rocks, stones, tree stumps, and other foreign objects with the cutting attachment.
If cutting attachment strikes an obstruction, stop engine immediately and inspect cutting attachment for damage.
cutting clear
Lay the unit down on a clear area and set the controls for starting. Be sure the cutting attachment cannot contact the ground or any obstruction.
Hold the unit firmly down so you will not lose control during starting. Do not start the unit in the air, or from the harness. The unit could swing into your leg or an obstruction if you lose control.
15 m
Do not raise the cutting attachment above knee height. If raised higher, the cutting attachment will be more directly in line with your face. Thrown objects may hit your face and eyes.
Wear the recommended protective gear.
Never operate the unit without the proper guards, shoulder harness and other protective devices.
Never operate the unit without good visibility and light.
Do not allow anyone to enter the operating DANGER ZONE with you. The danger zone is an area of 15 m in radius.
Insist that persons in the RISK ZONE beyond the danger zone wear eye protection to protect them from thrown objects. If the unit must be used where there are unprotected people, operate at a low throttle speed to reduce the risk.
Ensure that there are no children, bystanders, and pets in the work area. Keep all children, bystanders and fellow workers outside 15 m radius for brushcutters/ grasstrimmers.
Stop the engine before leaving the machine, children are not allowed to use the machine, stop the machine between different working places.
If you are approached, stop the engine and cutting attachment immediately. Keep your hands and body away from silencer to prevent heat injury while the engine is hot.

Sudden vibration?
Shut down immediately!
Shut down immediately if the unit starts to shake or vibrate.
A sudden vibration is a sign there may be dangerous trouble, such as a broken flywheel, clutch or cutting attachment, or loose parts.

Painful or numb fingers?
See your doctor immediatelty!
VIBRATION AND COLD
It is believed that a condition called Raynaud’s Phenomenon which affects the fingers of certain individuals may be brought about by exposure to vibration and cold.
Exposure to vibration and cold may cause tingling and burning, followed by loss of colour and numbness in the fingers.
The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.
•Keep your body warm, especially the head and neck, feet and ankles, and hands and wrists.
•Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks, and also by not smoking.
•Limit the number of hours of operation.
Try to fill each day with jobs where operating the trimmer or other hand-held power equipment is not required.
•If you experience discomfort redness and swelling of the fingers, followed by whitening and loss of feeling, consult your physician before exposing yourself further to cold and vibration.
REPETITIVE STRESS INJURIES
It is believed that over-using the muscles and tendons of the fingers, hands, arms and shoulders may cause soreness, swelling, numbness, weakness and extreme pain to the areas just mentioned. Certain repetitive hand activities may put you at a high risk for developing a repetitive stress injury (RSI).
To reduce the risk of RSI, do the following:
•Avoid using your wrist in a bent, extended or twisted position.
•Take periodic breaks to minimize repetition and rest your hands. Reduce the speed and force in which you do the repetitive movement.
•Do exercises to strengthen hand and arm muscles.
•See a doctor if you feel tingling, numbness or pain in your fingers, hands, wrists or arms. The sooner RSI is diagnosed, the more likely permanent nerve and muscle damage can be prevented.
