Safety Precautions
I. General Operation
� Read, understand, and follow all instructions on the machine and in the manual before starting. Be thoroughly familiar with the controls and the proper use of the machine before starting. � Do not put hands or feet near or under rotating parts. � Keep all parts of your body away from muf�er and spinning line. A hot muf�er can cause serious burns. � Only allow responsible individuals, who are familiar with the instructions, to operate the machine. � Stay away from breakable objects, such as house windows, auto glass, greenhouses, etc. � Clear the area of objects such as rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by the spinning lines. � Be sure the area is clear of other people before trimming, particularly small children and pets. Stop machine if anyone enters the area. � Wear appropriate protective clothing such as a long-sleeved shirt or jacket. Also wear long trousers or slacks. Leg protection is recommended. Do not wear shorts. � Do not wear loose clothing, which could get caught in this equipment. � Do not operate the machine when barefoot or wearing open sandals. Always wear work gloves and sturdy footwear. Leather work shoes or short boots work well for most people.These will protect the operator�s ankles and shins from small sticks, splinters, and other debris, and improve traction. � Always wear safety goggles or safety glasses with side shields when operating machine. � Wear hearing protection. � Do not pull machine backwards unless absolutely necessary. Always look down and behind before and while moving backwards. � Do not operate the machine without proper guards, plates or other safety protective devices in place. � See manufacturer�s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer. � Never use blades, wire, or �ailing devices. This unit is designed for �exible plastic line trimmer use only. Use of other accessories or attachments will increase the risk of injury. � Stop the rotating trimmer head when crossing gravel drives, walks, or roads. Wait for the cutting lines to stop rotating. � Stop the engine (motor) whenever you leave the equipment and allow it to cool, before cleaning, repairing or inspecting the unit. Be sure the trimmer head and all moving parts have stopped. � Operate only in daylight or good arti�cial light. � Do not operate the machine while tired, ill or under the in�uence of alcohol or drugs. � Never operate machine in wet grass. Always be sure of your footing: keep a �rm hold on the handle and walk; never run. � If the equipment should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble.

II. Slope Operation
Slopes are a major factor related to slip and fall accidents, which can result in severe injury. All slopes require extra caution. If you feel uneasy on a slope, do not trim it.

DO:
� Trim across the face of slopes: never up and down. Exercise extreme caution when changing direction on slopes. � Remove obstacles such as rocks, tree limbs, etc. � Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

DO NOT:
� Do not trim near drop-offs, ditches or embankments. The operator could lose footing or balance. � Do not trim excessively steep slopes. � Do not trim on wet grass. Reduced footing could cause slipping.

III. Children
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the trimming activity. Never assume that children will remain where you last saw them. � Keep children out of the trimming area and under the watchful care of another responsible adult. � Be alert and turn machine off if children enter the area. � Before and while moving backwards, look behind and down for small children. � Never allow children to operate the machine. � Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

IV. Service
� Use extra care in handling petrol and other fuels. They are �ammable and vapors are explosive. - Use only an approved container. - Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling. Do not smoke. - Never refuel the machine indoors. - Never store the machine or fuel container inside where there is an open �ame, such as a water heater. - Move away from fueling site before starting engine. � Never run a machine inside a closed area. � Never make adjustments or repairs with the engine (motor) running. Disconnect the spark plug wire, and keep the wire away from the plug to prevent accidental starting. � Keep nuts and bolts, especially trimmer head and engine bolts, tight and keep equipment in good condition. � Never tamper with safety devices. Check their proper operation regularly. � Keep machine free of grass, leaves, or other debris buildup. Clean oil or fuel spillage.
