MAINTENANCE

Raker (depth gauge) clearance.

1.Too low increases the potential for kickback.

2.Not low enough decreases cutting ability.

If the cutter teeth hit hard objects such as nails and stones, or are abraded by mud or sand on the wood, have the Homelite Service Center sharpen the chain.

Note: Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage are present in the areas indicated, have the drive sprocket replaced by a Homelite Service Center.

SHARPENING THE CUTTERS

See Figures 50 through 54.

Be careful to file all cutters to the specified angles and to the same length, as fast cutting can only be obtained when all cutters are uniform.

1.Wear gloves for protection.

2.Tension the chain prior to sharpening.

Note: Refer to “Maintenance – Adjusting the Chain Tension” earlier in this manual.

3.Use a 5/32 in. diameter round file and holder. Do all of your filing at the midpoint of the bar.

4.Keep the file level with the top plate of the tooth. Do not let the file dip or rock.

5.Using light but firm pressure. Stroke towards the front corner of the tooth.

6.Lift the file away from the steel on each return stroke.

7.Put a few firm strokes on every tooth. File all left hand cutters in one direction. Then move to the other side and file the right hand cutters in the opposite direction.

8.Remove filings from the file with a wire brush.

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.
