Start the motor as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar is free of contact).

Grasp the tubular handle firmly with one hand and hold the grip with the other.

Switch on the motor and press the hand guard (I/7) in the direction of the arrow with the back of your hand until the chain brake engages. The chain should stop immediately. Switch the motor off Immediately and release the chain brake.

IMPORTANT: If the saw chain does not stop instantly when you carry out this test, do not under any circum- stances use the saw! Take the chain saw to a MAKITA service center.

Checking the chain lubrication

J

Never saw when a sufficient chain lubrication is not guaranteed. Otherwise the life of the sawing device will be reduced. Before starting work check the oil level in the tank and the oil feeding. Check the fed oil quantity by following the instructions below:

-Start the electric chain saw.

-Hold the running chain saw approx. 15 cm above a trunk or the ground (use an appropriate surface).

If the lubrication is sufficient, you will see a light oiltrace because oil will be centrifuged from the chain saw.

Using the chain saw

Always be sure of your footing and hold the chain saw firmly with both hands while the motor is running.

Felling a tree

When bucking and felling operations are being performed by two or more persons, at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree

does make contact with any utility line, the utility company should be notified immediately.

The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.

A retreat path should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall as shown

in Fig. A. The next working place is at least 2 tree lengths away.

Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall. Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to be made.

Notching undercut

Make the notch 1/3 the diameter of the tree, perpendicular to the direction of fall as shown in Fig.B. Make the lower hori- zontal notching cut first. This will help to avoid pinching of either the saw chain or the guide bar when the second notch is being made.

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.
