Adjusting the tension:

Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

You can adjust the chain tension by loosen- ing the chain brake nuts and turning the ad- justing screw 1/4 of a turn while lifting up on the bar.

SIf chain is too tight, turn adjusting screw 1/4 turn counterclockwise.

SIf chain is too loose, turn adjusting screw 1/4 turn clockwise.

S Lift up the tip of the bar and tighten the chain brake nuts with the combination screwdriver/wrench.

SRecheck chain tension.

WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury.

FUELING & LUBRICATION

FUELING ENGINE

WARNING: Remove fuel cap slowly when refueling.

This engine is certified to operate on unleaded gasoline. Before operation, gasoline should be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. (A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline). DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules listed under HANDLE FUEL WITH CAUTION.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar.

In freezing weather oil will thicken, making it necessary to thin bar and chain oil with a small amount (5 to 10%) of #1 Diesel Fuel or kero- sene. Bar and chain oil must be free flowing for the oil system to pump enough oil for adequate lubrication.

Genuine Husqvarna→ bar and chain oil is rec- ommended to protect your unit against exces- sive wear from heat and friction. Husqvarna→ oil resists high temperature thinning.

If Husqvarna→ bar oil is not available, use a good grade SAE 30 oil.

SNever use waste oil for bar and chain lu- brication.

SAlways stop the engine before removing the oil cap.

IMPORTANT

Experience indicates that alcohol--blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See STORAGE section for addi- tional information.

142 specifications

The Husqvarna 142 is a powerful and versatile chainsaw designed for homeowners and outdoor enthusiasts who require a reliable tool for various cutting tasks. This model combines performance, efficiency, and ease of use, making it an excellent choice for those who need to tackle firewood cutting, tree pruning, or other general yard work.

One of the main features of the Husqvarna 142 is its lightweight design. Weighing only around 10.8 lbs, it is easy to maneuver, ensuring less fatigue during extended use. This makes it particularly appealing for those who may not have the physical strength required for heavier models. Despite its light weight, the Husqvarna 142 does not compromise on power. It is equipped with a 2.0 horsepower, 40cc two-stroke engine, providing ample cutting capability for most household tasks.

The chainsaw comes with Husqvarna’s unique Air Injection technology, which is designed to enhance engine performance by utilizing centrifugal force to separate larger dust and debris particles before they reach the air filter. This system helps to keep the air filter clean for longer periods, reducing maintenance needs and ensuring efficient operation over time. Additionally, the engine features a fuel-saving X-Torq system, which reduces fuel consumption and emissions without sacrificing performance. This makes the Husqvarna 142 not only cost-effective but also environmentally friendly.

Comfort and safety are prioritized in the design of the Husqvarna 142. The chainsaw is equipped with an anti-vibration system that minimizes user fatigue and discomfort, allowing for more extended periods of use. The protective handguard helps prevent injuries, and the chain brake feature stops the chain quickly in the event of kickback, ensuring safe operation.

Another noteworthy characteristic of the Husqvarna 142 is its easy-to-use tensioning system for adjusting the chain. The side-mounted chain tensioner allows for quick and tool-free adjustments, ensuring the chain remains properly tensioned for optimal performance.

In summary, the Husqvarna 142 is a well-rounded chainsaw that offers a combination of power, efficiency, and user-friendly features. Its lightweight design, advanced technologies, and safety features make it an excellent choice for homeowners looking to manage their outdoor spaces efficiently and effectively. Whether you are cutting firewood, trimming branches, or clearing debris, the Husqvarna 142 delivers reliable performance to meet your needs.
