MAINTENANCE

MAINTAINING THE GUIDE BAR

See Figure 60.

CAUTION:

Make sure the chain has stopped before you do any work on the saw.

Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage.

Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur.

A bar with any of the following faults should be replaced:

■Wear inside the bar rails that permits the chain to lay over sideways

■Bent guide bar

■Cracked or broken rails

■Spread rails

In addition, lubricate guide bars (with a sprocket at their tip) weekly. Using a grease syringe, lubricate weekly in the lubricating hole.

Turn the guide bar and check that the lubrication holes and chain groove are free from impurities.

MAINTAINING THE SAFE-T-TIP NOSE GUARD

See Figures 61 and 62.

CAUTION:

Make sure the chain has stopped before you do any work on the saw.

WARNING:

Although the guide bar comes with a SAFE-T-TIP anti- kickback device already installed, you need to check the tightness of the mounting screw before each use.

Tighten the mounting screw of the nose guard as in- structed below. These are specially hardened screws. If you cannot install the screw tightly, replace both the screw and the SAFE-T-TIP before further operation. Do not replace the screw with an ordinary screw.

In addition to preventing chain contact with solid objects at the nose of the bar, the SAFE-T-TIP also helps keep the chain away from abrasive surfaces, such as the ground. Keep it on the right hand side of the bar where it will be between the chain and the ground during flush with ground cutting.

The mounting screw requires a 5/16 in. wrench (or adjustable wrench) to achieve the recommended tight- ness of 35 to 45 in.lb. (4-5 Nm). A tightness within this range can be achieved by using the following method.

1.Tighten the screw with your finger.

2.Tighten the screw an additional 3/4 of a turn using a wrench.

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.
