Replacing the saw chain

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

A

B

Check the sprocket (A/1) before mounting a new chain.

The sprocket is located underneath the clutch drum (I/2).

CAUTION:

Worn out sprockets (B) may damage the new chain and must therefore be replaced.

Do not attempt to replace the sprocket yourself. Sprocket replacement requires special training and tools and must be done at a MAKITA service center.

Inspecting and replacing the carbon brushes

IMPORTANT:

Inspect the carbon brushes at regular intervals! A notch on the brush shows the limit of wear.

NOTE:

The carbon brush is very delicate, so be careful not to let it drop.

When taking it out, be sure to note the position it was installed in, since each brush is run in with the rotor.

-Use the combination wrench to unscrew the cover (C/2), and then pull out the brush (C/3).

-If the wear limit has not yet been reached, put the brush back in the same position and screw the cover (C/2) back on.

-Run the saw briefly (about a minute) so the brushes can run in again.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by MAKITA Authorized or Factory Service Centers, always using MAKITA replacement parts.

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 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.
