RULES FOR SAFE OPERATION A. Kickback Safety Precautions for Chain Saw Users WARNING! KICKBACK may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning fast reverse REACTION, Kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

OPERATOR SAFETY VIBRATION AND COLD EYE AND HEARING PROTECTION • 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 color and numbness in the fingers. The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.
SPARK ARRESTOR MUFFLER • The spark arrestor muffler controls the exhaust noise and prevents hot, glowing particles of carbon from leaving the muffler. Make sure the spark arrestor screen is in good repair and properly seated in the muffler. • Certain internal combustion engines operated on forest, brush, and/or grass-covered areas in the states of Washington, Oregon, Idaho, California, Minnesota, New Jersey and Maine, are required to be equipped with a spark arrestor.
PREPARATION FOR USE WARNING WARNING Saw chain is sharp! Always wear gloves when handling assembly, otherwise serious personal injury may result. Momentary stop switch automatically returns to run position. Engine can start unintentionally. Always remove spark plug lead from spark plug before assembling or performing maintenance procedures or serious personal injury may result.
ADJUSTING CHAIN TENSION Unlock chain brake IMPORTANT Always loosen clutch cover nuts before turning the chain tension adjuster, otherwise the clutch cover and tensioner will be damaged. 1. Remove spark plug lead. (See maintenance section) 2. Unlock the chain brake and loosen a clutch cover nuts, if necessary. 3. Hold the bar nose up, and turn the tension adjuster clockwise until chain fits snugly against underside of the bar.
FUEL AND LUBRICANT FUEL STATEMENT Gasoline - Use 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. ECHO Red Armor™ Fuel (Power Fuel™) is 93 octane, ethanol-free fuel premixed with ECHO Red Armor™ engine oil at 50:1 ratio.
HANDLING FUEL Mixing Instructions 1. Fill an approved fuel container with half of the required amount of gasoline. DANGER Fuel is very flammable. Use extreme care when mixing, storing or handling or serious personal injury may result. • Use an approved fuel container. • 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.
CHAIN LUBRICANT Proper lubrication of the chain while in operation reduces friction between the chain and the guide bar to a minimum and assures a longer service life. Cap indication Oil/fuel tanks are indicated by the following illustrations. Oil tank cap • Use bar and chain oil of high quality for this purpose. • Do not use used or reclaimed oil to avoid various oiler problems. • Use ECHO bar and chain oil. • Use bar and chain oil of the following grades: SAE No. 30 ������� in summer SAE No.
OPERATION WARNING Chain brake Throttle trigger lockout Throttle trigger • After choke control knob is pulled and then knob is returned to original position, throttle remains slightly open (fast idle latch condition). • The chain will attempt to move when engine is started with fast idle throttle latch engaged. • Do not start engine before chain brake is activated.
WHEN THE ENGINE IS COLD Chain brake CAUTION Make sure the bar and chain are free from any obstruction when starting the chain saw. Throttle trigger lockout • Move chain brake lever fully forward to lock chain brake before starting. • Fill the fuel tank with fuel mixture. It is not permitted to fill fuel above the shoulder level of fuel tank. • Fill the chain oil tank with lubricant. Do not over fill. • Pull choke control knob all the way out.
RUNNING Unlock chain brake • When engine starts, keep idling for a few minutes. • Set the brake lever in the unlocked position before starting to cut. • Pull throttle trigger gradually and increase revolution of the engine. • The chain starts running when the engine reaches 4,150 r/min approximately. • Confirm proper acceleration and lubrication of chain and bar. • Do not run the engine at high speed unnecessarily. • Be sure that saw chain stops moving when throttle trigger is released.
CUTTING INSTRUCTION GENERAL CAUTION • Read the ECHO “CHAIN SAW SAFETY MANUAL” included with your chain saw for additional cutting and safety instructions. • Wear suitable hearing protection such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. • Do not let the tip of the bar touch anything while the engine is running. At cutting speed the chain is moving at a high rate of speed.
FELLING THE TREE A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power-line, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! Before cutting, clear the area around the tree. You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat.
LIMBING Limbing a fallen tree is much the same as bucking. Never stand on the tree that you are limbing. When limbing, caution is the word. Be careful of the tip touching other limbs. Always use both hands. Don’t cut with the saw overhead or aligned vertically with your body. If the saw should kickback, you may not have enough control to prevent possible injury. BUCKING Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations.
CHAIN BRAKE OPERATION Kickback motion • Set the lever in the unlocked position before starting to cut. • If the brake is tripped by kickback reaction, the chain will stop immediately. Release the throttle to avoid possible damage to the engine or clutch. • Do not attempt to operate the engine with the brake locked. Improper thrust cutting Kickback motion When the bar nose hits another tree, etc.
AUTOMATIC CHAIN BRAKE End of the guide bar may be placed at the height of about 50 cm (20 in.). Kickback produced from the tip of the guide bar will trip the automatic chain brake. To make sure that the automatic chain brake operates properly, follow these steps: 1. Stop the engine. 2. Hold the saw with the guide bar approximately 50 cm (20 in.) above a wooden surface. Right hand should hold the rear handle, and left hand should hold the front handle. 3.
CHAIN AND GUIDE BAR COMBINATION The following combinations are recommended for model CS-4510. Guide bar Length mm (in.)
