SAFETY GT-225
The components of this machine generate an electromagnetic field during operation, which can interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with pacemakers should consult with their physician and the pacemaker manufacturer before operating this machine. In the absence of such information, ECHO does not recommend the use of this machine by anyone who has a pacemaker.
Extended Operation and Extreme Conditions
Prolonged exposure to cold and/or vibration can result in injury.
Read and follow all safety and operation instructions to minimize risk of injury. Failure to follow instructions can result in painful wrist/hand/arm injuries.
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 sensations, followed by loss of color 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, neck, feet, ankles, hands, and wrists.
• Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks, and also by not smoking.
• Limit the hours of operation. Try to fill each day with jobs where operating the unit 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 further exposing yourself to cold and vibration.

GT-225 SAFETY
Repetitive Stress Injuries (RSI)
It is believed that overusing the muscles and tendons of the fingers, hands, arms, and shoulders may cause soreness, swelling, numbness, weakness, and extreme pain in those areas. Certain repetitive hand activities may put you at a high risk for developing a Repetitive Stress Injury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome (CTS), which could occur when your wrist swells and squeezes a vital nerve that runs through the area. Some believe that prolonged exposure to vibration may contribute to
CTS. CTS can cause severe pain for months or even years.
To reduce the risk of RSI/CTS, do the following
• Avoid using your wrist in a bent, extended, or twisted position.
Instead try to maintain a straight wrist position. Also, when grasping, use your whole hand, not just the thumb and index finger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive movement.
• Do exercises to strengthen the hand and arm muscles.
• Immediately stop using all power equipment and consult a doctor if you feel tingling, numbness, or pain in the fingers, hands, wrists, or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve and muscle damage can be prevented.
All over head electrical conductors and communications wires can have electricity flow with high voltages. This unit is not insulated against electrical current. Never touch wires directly or indirectly, otherwise serious injury or death can result.
Do not operate this product indoors or in inadequately ventilated areas. Engine exhaust contains poisonous emissions and can cause serious injury or death.

Moving parts can amputate fingers or cause severe injuries.
Keep hands, clothing and loose objects away from all openings.
Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause unconsciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust is directed away from your face and body.
Operation of this equipment may create sparks that can start fires around dry vegetation. This unit is equipped with a spark arrestor to prevent discharge of hot particles from the engine.
Metal cutters can also create sparks if the cutter strikes rocks, metal, or other hard objects. Contact local fire authorities for laws or regulations regarding fire prevention requirements.
Fuel
Diesel fuels and alternative fuels, such as E-15 (15% ethanol),
E-85 (85% ethanol) or any fuels not meeting ECHO requirements are NOT approved for use in ECHO 2-stroke gasoline engines.
Use of diesel or alternative fuels can cause performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to, improper clutch engagement. Diesel or alternative fuels can also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.

GT-225 OPERATION
Fuel Requirements
Gasoline - Use fresh (purchased within the last 30 days from the pump) 89
Octane [R+M/2] (mid grade or higher) gasoline known to be good quality.
Gasoline may contain up to 10% Ethanol (grain alcohol) or 15% MTBE
(methyl tertiary-butyl ether). Gasoline containing methanol (wood alcohol) is
NOT approved. Use of ECHO branded fuel is recommended to extend engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.
Two Stroke Oil - A two-stroke engine oil, such as ECHO branded 2-stroke oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must be used. ECHO branded 2-stroke oils meet these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-
EGD (ISO/CD 13738) and J.A.S.O. M345-FD certified oil will void the twostroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other additives that may be harmful if swallowed. Heated oil can release vapors that can cause flash fire, or ignite with explosive force. Read and follow the oil manufacturer’s instructions, and observe all safety warnings and precautions for handling flammable liquids. For more detailed safety and first aid information, visit www.echo-usa.com for a copy of the Material
Safety Data Sheet.

◆
KEEP OUT OF REACH OF CHILDREN.
If swallowed, do not induce vomiting. CALL PHYSICIAN OR
A POISON CONTROL CENTER IMMEDIATELY.
WEAR SAFETY GLASSES when mixing or handling.
AVOID repeated or prolonged skin contact.
◆ AVOID inhaling oil mists or vapors.
ECHO branded 2-stroke oils may be mixed at 50:1 ratio for application in all ECHO engines sold in the past regardless of ratio specified in those manuals.

Handling Fuel
GT-225
Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury will result.
◆
Use an approved fuel container. Mark fuel containers as containing 2-stroke mixture fuel.
◆
◆
◆
DO NOT smoke near fuel.
DO NOT allow flames or sparks near fuel.
Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
◆
◆
◆
◆
◆
◆
NEVER refuel a unit when the engine is HOT or RUNNING!
DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
DO NOT overfill fuel tank. Wipe up spills immediately.
Securely tighten fuel tank cap and close fuel container after refueling.
Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
Move at least 3 m (10 ft.) from refueling location before starting the engine.
Gasoline vapor is heavier than air, and can travel along the ground to nearby sources of ignition such as electrical motors, pilot lights, and hot or running engines. Vapors ignited by an ignition source can flash back to the fuel container, resulting in an explosion, fire, serious or fatal injuries, and extensive property damage.

Applications
OPERATION
Do Not install blades on GT (Curved Shaft) trimmers.
Operating Techniques - Nylon Line Head
Nylon line heads may be used for trimming, scything, edging, and scalping of grass and light weeds.
Trimming
Feed the spinning line into the material to be cut. Tilt cutting head to the left while cutting to direct debris away from the operator.
Scything
Scything - Swing the cutting head in a level arc, gradually feeding the line into the material being cut. Move forward with each arc to cut a swath.
Width of cutting swath depends on arc. Use a larger arc for a wider swath, or a smaller arc for a narrow swath. Keep line head tilted to direct cutting debris forward or away from you.
Edging and Scalping
Both of these are done with the nylon line cutting head tilted at a steep angle. Scalping is removing top growth, leaving the earth bare. Edging is trimming the grass back where it has spread over a pavement or driveway.
During both edging and scalping, hold the unit at a steep angle in a position where the debris, and any dislodged dirt and stone, will not come back towards you even if it ricochets off the hard surface.
General
• Debris flows in direction of line head rotation. Change line head position to assure debris flow is directed away from operator.
• Keep cutting line away from wire fences to avoid entanglement.
• Operate trimmer only with cutting head below knee height.

Operating a poorly maintained unit can result in serious injuries to operator or bystanders. Always follow all maintenance instructions as written, otherwise serious personal injury can result.
Your unit is designed to provide many hours of trouble free service. Regular scheduled maintenance will help your unit achieve that goal. If you are unsure or are not equipped with the necessary tools, we recommend that you take your unit to a Servicing Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have the Dealer do it, each maintenance task has been graded. If the task is not listed, see your
Dealer for repairs.
The use of emission control components other than those specifically designed for this unit is a violation of federal law.

MAINTENANCE
Cooling System
Level 2.
GT-225
To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder fin area. This flow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching the cylinder.
• Dust and grass build up on the outside of the cylinder. This build up insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cooling fins is considered “Normal Maintenance.”
Any failure attributed to lack of maintenance is not warranted.
1.
Remove spark plug lead.
2.
Close choke (COLD START
[ ] position). This prevents dirt from entering the carburetor throat when the air filter is removed. Remove air cleaner cover (A).
3.
Remove engine cover (B).

Carburetor Adjustment
Level 2.
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting and durability performance up to 330 m (1100 ft.) above sea level (ASL)
(96.0 kPa). To maintain proper engine operation and emission compliance above 330 m (1100 ft.) ASL the carburetor may need to be adjusted by an authorized service dealer.
