GENERAL SAFETY RULES

WARNING:

The warnings, labels, and instructions found in this section of the operator's manual are for your safety. Failure to follow all instructions may result in serious personal injury.

Safe operation of this tool requires that you read and understand this operator's manual and all labels affixed to the tool. Safety is a combination of using common sense, staying alert, and knowing how your saw works.

READ ALL INSTRUCTIONS

■KNOW YOUR TOOL. Read the operator's manual carefully. Learn the saw's applications and limitations as well as the specific potential hazards related to this tool.

■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 toward the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. DO NOT rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

1.With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

2.Keep a good firm grip on the saw with both hands when the engine is running. Place your right hand on the rear handle and your left hand on the front handle with your thumbs and fingers encircling the chain saw handles. A firm grip together with a stiff left arm will help you maintain control of the saw if kickback occurs.

3.Make sure that the area in which you are cutting is free from obstructions. DO NOT let the nose of the guide bar contact a log, branch, fence, or any other obstruction that could be hit while you are operating the saw.

4.Cut at high engine speeds. Always cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.

5.Do not overreach or cut above chest height.

6.Follow the manufacturer's sharpening and maintenance instructions for the saw chain.

7.Only use replacement bars and chains specified by the manufacturer or the equivalent.

■DO NOT OPERATE A CHAIN SAW WITH ONE HAND. Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use.

■DO NOT OPERATE A CHAIN SAW WHEN YOU ARE FATIGUED. Never operate a chain saw when you are tired or under the influence of medication, drugs, or alcohol.

■USE SAFETY FOOTWEAR. Wear snug-fitting clothing, protective gloves, and eye, hearing, and head protection devices.

■DO NOT STAND ON ANY UNSTABLE SURFACE while using your chain saw, that includes ladders, scaffolds, trees, etc.

■USE CAUTION WHEN HANDLING FUEL. Move the chain saw at least 30 feet (9 m) from the fueling point before starting the engine.

■DO NOT ALLOW OTHER PERSONS to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.

■DO NOT START CUTTING until you have a clear work area, secure footing, and a planned retreat path from the falling tree.

■KEEP ALL PARTS OF YOUR BODY away from the saw chain when the engine is running.

■ALWAYS CARRY THE CHAIN SAW WITH THE ENGINE STOPPED AND THE BRAKE ENGAGED, the guide bar and saw chain to the rear, and the muffler away from your body. When transporting the chain saw, use the appropriate guide bar scabbard.

■DO NOT OPERATE A CHAIN SAW THAT IS DAMAGED, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

■SHUT OFF THE ENGINE before setting the chain saw down. DO NOT leave the engine running unattended.

■USE EXTREME CAUTION when cutting small-size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

■WHEN CUTTING A LIMB that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released.

■KEEP THE HANDLES dry, clean, and free of oil or fuel mixture.

■OPERATE THE CHAIN SAW ONLY in well-ventilated areas.

■DO NOT OPERATE A CHAIN SAW IN A TREE unless you have been specifically trained to do so.

UT10510 specifications

The Homelite UT10510 chainsaw is a versatile and efficient tool designed for both novice and experienced users who require a dependable saw for various tasks, from trimming and pruning to heavier cutting jobs. Known for its power and ease of use, the UT10510 is a reliable addition to any toolbox.

One of the main features of the Homelite UT10510 is its 10-inch cutting bar, which provides a perfect balance between maneuverability and cutting capacity. This size makes it ideal for tackling small to medium-sized branches, allowing users to handle tasks quickly and efficiently. It is also lightweight, reducing user fatigue during extended use, a benefit that is particularly important for those who may need to work for prolonged periods.

The UT10510 is powered by a gas engine, providing a robust 25cc of power. This engine allows for strong performance, enabling the saw to cut through tougher materials with relative ease. Additionally, the gas-powered design offers the advantage of being more portable than electric models, as it does not require a power source or long extension cords.

Another noteworthy technology incorporated into the Homelite UT10510 is its automatic chain lubrication system. This feature ensures that the chain remains well-lubricated during operation, which not only prolongs the life of the chain but also enhances cutting efficiency. A well-lubricated chain reduces friction, allowing for smoother cuts and reducing the risk of overheating.

Additionally, the UT10510 includes a tool-free chain tensioning system, which makes it easy for users to quickly adjust the chain tension without the need for additional tools. This feature is particularly useful for those who may not have extensive experience with chainsaw maintenance, as it simplifies what can be an otherwise complicated process.

Safety is also a significant consideration in the design of the Homelite UT10510. It features a chain brake that stops the chain immediately in case of kickback. This safety feature is critical for reducing the risk of accidents while operating the saw.

In summary, the Homelite UT10510 is a compact, powerful chainsaw designed for versatility and ease of use. With its effective 10-inch cutting bar, reliable gas engine, automatic chain lubrication, tool-free chain tensioning, and built-in safety features, it stands out as a practical choice for both casual users and those looking to handle more demanding cutting tasks. Whether you need to trim branches in your yard or cut firewood, the UT10510 is designed to meet your needs efficiently.
