Felling back cut

Make the felling back cut at least 2 inches (50.8 mm) higher than the horizontal notching cut as shown in Fig. B. Keep the felling back cut parallel to the horizontal notching cut. Make the felling back cut so enough wood is teft to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge.

As the felling cut gets close to the hinge the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminum to open the cut and drop the tree along the desired line of fall. When the tree begins to fall remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned. Be alert for overhead limbs falling and watch your footing.

Limbing a tree

Limbing is removing the branches from a fallen tree. When limbing, leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut as shown in Fig. C. Branches under tension should be cut from the bottom up to avoid binding the chain saw.

Bucking a log

Bucking is cutting a log into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log shoutd be raised and supported by the use of limbs, logs or chocks. Follow the sim- ple directions for easy cutting.

When the log is supported along its entire Iength as shown in Fig. D, it is cut from the top (overbuck).

When the log is supported on one end, as shown in Fig. E, cut 1/3 the diameter from the underside (underbuck ). Then make the finished cut by overbucking to meet the first cut.

When the log is supported on both ends, as shown in Fig. F, cut 1/3 of that diameter from the top overbuck. Then make the finished cut by underbucking the lower 2/3 to meet the first cut.

When bucking on a slope, always stand on the uphill side of the log, as shown in Fig. G. When "cutting through", to maintain complete control, release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Don't let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor before moving from tree to tree.

Carrying tool

Carry the tool by the front handle with the tool turned off, finger off the switch. Use the chain protection cover to cover the guide bar and the saw chain.

LIMB CUT

Keep work off ground

Leave support limbs until log is cut

C

Cut from top (overbuck)

avoid cutting earth

D

2nd cut overbuck (2/3 diameter) to meet 1st cut (to avoid pinching)

Tension side

Pressure side

1st cut underbuck (1/3 diameter) to avoid splintering

E

1st cut overbuck (1/3 diameter) to avoid splintering

Pressure side

Tension side

2nd cut underbuck (2/3 diameter) to meet 1st cut (to avoid pinching)

F

Stand on uphill side when cutting because log may roll.

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.
