CS-4510 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.
SAFETY CS-4510 Rules for Safe Operation Kickback Safety Precautions for Chainsaw Users 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.
CS-4510 SAFETY 2. Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chainsaw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go. 3. Make sure that the area in which you are cutting is free from obstructions.
SAFETY CS-4510 Testing the Brake • Start the engine on a solid level surface and run at a fast idle until warm. • Hold the saw firmly by the handles and accelerate the engine to a fast idle. • Slowly operate the chain brake lever while holding the saw firmly on the ground. When the brake lever trips, the chain should stop. Immediately release the throttle trigger. Do not allow the saw to tip forward in order to avoid damage to the chain.
CS-4510 ANSI Standard B175.1 and CSA Z62.1.3 stipulate that the brake shall stop the chain 0.12 seconds at an engine speed of 13,500 RPM. It is the responsibility of the owner/ operator to ensure that the brake is serviced, adjusted and tested strictly in accordance with the instructions as detailed here in order to ensure that the brake performance is maintained in compliance with the Standards B175.1 and CSA Z62.1.3. SAFETY 35 cm (14 in.
SAFETY CS-4510 Other Safety Precautions 1. Do not operate a chainsaw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chainsaw is intended for twohanded use. 2. Do not operate a chainsaw when you are fatigued. 3. Use safety footwear, snug-fitting clothing and protective gloves. Wear eye, hearing, and head protection devices. 4. Use caution when handling fuel.
CS-4510 SAFETY 17. All chainsaw service, other than items listed in the operator’s manual maintenance instructions, should be performed by competent service personnel. For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and could subsequently cause the flywheel to burst. 18. When transporting your chainsaw, use the appropriate guide bar cover. 19.
SAFETY CS-4510 Always keep exhaust area clear of flammable debris during transportation or when storing, otherwise serious property damage or personal injury may result. Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all openings.

OPERATION ◆ ◆ CS-4510 Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired. Use caution when handling fuel. Mix and pour fuel outdoors where there are no sparks and flames. Slowly remove the fuel cap only after stopping the engine and allowing the unit to cool. Do not smoke while fueling or mixing fuel. Move the unit at least 10 feet (3 m) from the fueling point before starting the engine.
CS-4510 OPERATION Storage - Fuel storage laws vary by locality. Contact your local government for the laws affecting your area. As a precaution, store fuel in an approved, airtight container. Store in a well-ventilated, unoccupied building, away from sparks and flames. • Empty the fuel tank prior to storing the unit. Return unused fuel to an approved fuel storage container. Stored two-stroke fuel can separate. ALWAYS shake fuel container thoroughly before each use.
OPERATION CS-4510 Chain Lubricant Note: Cap indication - Fuel/oil tanks are indicated by the following illustrations 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. • Use bar and chain oil of high quality for this purpose. • Do not use used or reclaimed oil to avoid various oiler problems. • Use high quality bar and chain oil.

Confirm proper acceleration and lubrication of chain and bar. 6. Do not run the engine at high speed unnecessarily. 7.
CS-4510 OPERATION Checking Chain Tension Chain tension should be checked frequently during work and corrected as necessary. Do not operate with a loose chain. Chain Lubrication Test Hold the chain just above a dry surface and open the throttle to half speed for 30 seconds. A thin line of “thrown” oil should be seen on the dry surface.
OPERATION CS-4510 Cutting Instructions General ◆ ◆ ◆ This chainsaw is designed for cutting wood. Do not cut metal, plastic or any non-wood material. 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.
CS-4510 OPERATION Start the engine, see that it is running properly. Squeeze the trigger to open the throttle wide open and start the cut. If the chain is properly sharpened, the cutting should be relatively effortless. It is not necessary to press down hard to make the saw cut. Pushing the saw too hard will slow the engine and cutting will actually be more difficult. Sap from palm trees may corrode metal parts unless proper saw maintenance is performed.
OPERATION CS-4510 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.
CS-4510 OPERATION To fell big trees with a diameter exceeding twice the bar length, start 3 the notching cuts from one side and draw the saw through to the other 1 side of the notch. Start the back cut on one side of the tree, pivoting the saw through to form the desired 2 hinge on that side. Then remove the saw for the second cut. Insert the saw in the first cut, very carefully so as not to cause kickback. The final cut is made by drawing the saw forward in the cut to reach the hinge.
OPERATION CS-4510 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. Uphill Position • Keep both hands on the handles at all times. • Support logs if possible. • When cutting on a slope or hillside, always stand uphill. Finish cut First cut Support Keep in mind that the wood is heavy and that it will bend and pinch the saw if improperly supported.
CS-4510 OPERATION Use of replacement saw chain and/or guide bar other than that specified, or operation without the optional Kick GuardTM in place, may cause severe kickback resulting in serious injury. Chain and guide bar gauge size must be identical. Use bar/chain combinations shown in the table above. Kick GuardTM (Optional) To purchase an optional Kick GuardTM contact your dealer. For the name of the ECHO dealer nearest you, call 1-800-432-ECHO (3246) or on the web at www.echo-usa.com.
