MAINTENANCE

Sharpening the saw chain

When working on the saw chain you must always pull out the power supply plug and wear protective gloves.

A

The chain needs sharpening when:

-the sawdust from sawing humid wood looks like wood flour.

-the saw chain penetrates the wood only under great pressure.

-the cutting edge is visibly damaged.

-the sawing device is pulled to the left or the right during the sawing operation. This is caused by uneven sharpening of the chain or by damage to one side of it.

Important: Sharpen frequently, but without removing too much metal!

Generally, 2-3 strokes of the file will be enough.

Have the chain resharpened in a service center when you have sharpened it yourself several times.

C

-All cutters must be sharpened to the same angle, 30°. Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain beakage.

-The 85° front rake of the cutter results from the cut depth of the round file. If the proper file is used in the right manner, the correct front rake will be obtained automatically.

Proper sharpening:

CAUTION:

Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)!

-All cutters must be of the same length (dimension a). Cutters with different lengths result in rough running of the chain and can cause cracks in the chain.

-Minimum cutter length is 0.11” (3 mm). Do not resharpen the chain when the minimum cutter length has been reached; at this point, the chain must be replaced (see the Extract from the spare-parts list and "Replacing the chain").

-The depth of the cut is determined by the difference in height between the depth limiter (round nose) and the cutting edge.

-The best results are obtained with a depth-limiter depth of

.025" (0.65 mm).

CAUTION:

Excessive depth increases the risk of kickback!

Files and how to work with them

-Use a special round file dia. 4.0 mm for chains for sharpening the chain. Normal round files are not appropriate for this work. See "Accessories" for the order number.

-The file should cut only when pushed forwards (arrow). Lift the file when leading it backwards.

-First sharpen the shortest cutter. The length of this cutter is then the standerd for all other cutters of the chain.

-Always guide the file as in fig. "D" shown.

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.
