OPERATION

4.Make the backcut level and horizontal, and at a mini- mum of 2 inches (5 cm) above the horizontal cut of the notch.

Note: Never cut through to the notch. Always leave a band of wood between the notch and back cut (approxi- mately 2 inches (5 cm) or 1/10 the diameter of the tree). This is called "hinge" or "hingewood". It controls the fall of the tree and prevents slipping or twisting or shoot- back of the tree off the stump.

On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. Drive wedges in, little by little, to help jack the tree over.

When bucking or felling with a wedge, it may be necessary to remove the SAFE-T-TIP anti-kickback device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip immediately.

5.As tree starts to fall, stop the chain saw and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way.

WARNING:

Never cut through to the notch when making a back cut. The hinge controls the fall of the tree, this is the section of wood between the notch and backcut.

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.
