Checking the chain tension

The chain has the proper tension when it lies against the bottom edge of the guide bar and can be easily pulled by hand about 5 mm (a little under 1/4") up from the guide bar.

Check the chain tension frequently - new chains tend to get longer during use!

When checking the chain tension the motor must be switched off and the power supply plug pulled out.

HINT:

Use 2 or 3 saw chains alternately for even wear of the chains, sprocket and guide bar running surfaces.

In order to guarantee a uniform wear of the groove in the bar the bar should be turned over whenever replacing the chain.

The UC 3000, UC 3500 and UC 4000 comes with an inertial chain brake as standard equipment. The chain brake engages automatically in case of kickback, which is caused by the tip contacting wood while the saw is running (see "SAFETY PRECAUTIONS", page 5).

The chain will stop within a fraction of a second.

Engaging the chain brake (braking)

In case of kickback the chain brake is engaged automatically by inertial motion of the hand guard (I/11).

To engage the chain brake manually, simply push the hand guard (I/11) forward (towards the tip of the saw) with your left hand (arrow 1).

Releasing the chain brake

Pull the hand guard (I/11) towards you (arrow 2) until you feel it catch. The brake is now released.

Note:

When the chain brake is actuated the power supply to the motor will be cut off. Testing of the chain brake is described on page 12.

Chain brake maintenance

SERVICE

The chain brake is a very important safety feature, and like any other part it is subject to a certain amount of wear. Regular inspection and maintenance is important for your personal safety, and can be properly performed only by a MAKITA service center.

UC 3000, UC 3500, UC 4000 specifications

Makita, a leader in power tools, has developed a range of electric chainsaws designed for efficiency, power, and user comfort. Among these, the UC 3000, UC 3500, and UC 4000 models stand out, each offering unique features tailored to different cutting needs.

The Makita UC 3000 is an excellent choice for light to medium-duty tasks. It sports a 3000-watt motor, providing ample power for trimming branches, cutting firewood, and general garden maintenance. One of its key features is the tool-less chain tensioning system, which allows users to adjust the chain quickly and safely without the need for additional tools. The UC 3000 is equipped with an automatic chain lubrication system that ensures the chain runs smoothly and maintains optimal performance. Weighing relatively light, this model promotes user comfort and reduces fatigue during prolonged use.

Moving up in power, the Makita UC 3500 delivers a robust 3500-watt motor. This model is well-suited for more demanding jobs, such as cutting larger trees or heavy-duty landscaping tasks. The UC 3500 also features the tool-less chain tensioning system, providing an efficient and hassle-free experience. The automatic oiling mechanism continues to support the chain’s health, ensuring longevity and consistent performance. Additionally, the UC 3500 includes an ergonomic design with a comfortable grip to minimize vibrations, enhancing user control during operation and improving overall safety.

The UC 4000 takes power and performance to the next level, boasting a strong 4000-watt motor. This model is ideal for professional landscapers and those who regularly undertake heavy-duty cutting tasks. The UC 4000 combines the convenient tool-less chain tensioning system and automatic lubrication features found in its smaller counterparts but also incorporates advanced safety features such as a kickback brake. This ensures immediate chain stoppage if the chainsaw is used improperly, increasing user safety significantly. The lightweight design paired with an ergonomic handle makes this model manageable for extended periods while providing excellent balance.

In summary, the Makita UC 3000, UC 3500, and UC 4000 offer a versatile range of electric chainsaws suitable for various applications. Each model combines effective motors with user-friendly features and innovative technologies, ensuring that users can tackle cutting jobs with confidence and efficiency. Whether for casual gardening or professional landscaping, Makita's chainsaws are built to meet the demands of users at any skill level.
