Hitachi brand chainsaws. Overview of the model range, technical characteristics

It took the Japanese company Hitachi just a few years to become practically the flagship of the market and compete with brands such as Stihl, Makita and Huskvarna. To be at the forefront, Hitachi uses engines with NewPureFir technology, which increases machine power by 20% and reduces harmful emissions by half.

It is also worth noting the ultra-reliable and high-quality Walbro carburetors and the latest air purification system.

The Hitachi company was founded back in 1910 in Japan and initially produced ammeters and voltmeters. Afterwards, production expanded to turbines, electrolysis, fans, etc. Constantly developing and improving, the company opens up new opportunities and creates the latest technologies that distinguish its products from the entire market.

Currently, Hitachi has more than 20,000 products, and there are more than 300 subsidiaries and enterprises around the world.

Purpose of the chainsaw

The Hitachi CS33EB chainsaw is primarily intended for household use. It is used most often for periodic and non-permanent maintenance of a small country house. This applies to the following types of tasks:

• pruning garden trees;
• small construction of buildings and structures.

Even an untrained person who does not have the appropriate skills and knowledge can use the Hitachi CS33EB chainsaw. This is due to its ergonomic design, its light weight, and ease of operation.

In some cases, the Hitachi CS33EB chainsaw can also be used to perform more professional large-scale tasks. This applies to work in the garden or pruning of trees by specialized enterprises.

Expert advice

The chain saw is powered by a two-stroke engine. This indicates that the device requires fuel to function, which requires mixing with oil.

When refueling the tool, it is important to ensure good ventilation. For the described chainsaw model, 89-octave unleaded gasoline is suitable

For operation it is necessary to use only original oil, which is intended for two-stroke engines. Hitachi CS33EB, reviews of which are presented in the article, can also work on a ready-made mixture. In this case, you need to adhere to the following ratios: 25 to 1 to 50 to 1.

Reviews

Most reviews on the Internet about the Hitachi CS33EB chainsaw are positive or neutral.

Konstantin, 35 years old. Among the advantages of the Hitachi CS33EB chainsaw, I would like to highlight its affordable cost, lightness and ease of use. The main disadvantage of this tool is the flimsy chain tensioner. I purchased a chainsaw to cut firewood in my garden. From the packaging after refueling, the device started only 5 times. No such difficulties arose during operation. In an hour we managed to cut three birch trees with a diameter of about 35 centimeters.

Vlad, 25 years old. The Hitachi CS33EB chainsaw starts well, both in cold and warm seasons. I didn't like the weak air filter, which slows down the startup process a bit. In terms of power and performance, I have not had any comments after using the tool for a long time.

Operating parameters of high-demand electric saw models

Hitachi CS35Y

The electric saw, with its own weight of 5.6 kg, is activated by a longitudinally mounted electric motor with a power of 2000 watts. The headset length of 350mm is fully sufficient for performing household and construction work.

The advantages of this model include:

• efficient cooling and lubrication of the saw chain due to built-in automation and a pump with adjustable capacity;
• tool-free tensioning of the saw chain;
• stability of speed during power surges and full protection against overloads;
• the presence of a SoftStart smooth start system.

Hitachi CS40Y

The popular Hitachi electric chain saw CS40Y series is identical in operating parameters to the CS35Y model. The tool has been improved to improve performance and operational safety. Measures taken to extend the working life and increase the reliability of overload protection.

Startup instructions

The Hitachi CS33EB chainsaw does not have any non-standard features of its operation. Its operating principle is fully consistent with similar chainsaws. That is why owners of this tool do not need a long time to prepare for the process of cutting wood. The main thing is to assemble the saw correctly. To do this, you need to adhere to the following algorithm of actions:

1. The front guard must be pulled towards the front handle. This will allow you to check whether the chain brake is affecting any other parts of the tool.
2. The guide bar clamping nuts must be removed. After this, the side housing should be removed. When installing a gear shock absorber, you should use two bolts.
3. First, the tire should be secured with bolts, and then pushed in the direction of the sprocket to the end.
4. Check that the direction of the saw chain is correct. After this, you need to adjust the chain on the sprocket.
5. The chain drive links must be guided into the groove of the tire. This applies to all its parties without exception.
6. Next you need to install the side housing, securing it accordingly.
7. Finally, lift the end of the guide bar and tighten the chain. To do this, use the tension adjustment bolt.
8. To operate, you need to use branded 92-octane unleaded gasoline. As a lubricant, you must purchase original oil for a two-stroke engine or a mixture of it in a ratio of 25:1 to 50:1.

Proper operation of the Hitachi CS33EB chainsaw is the key to long-term use of the tool. When purchasing, pay attention to modifications. If you need more performance and compactness, then buy an n5 saw with a 30cm bar. If you want to cut something large in diameter, then it is better to purchase the n6 version.

Do not forget that the tire on a chainsaw can be replaced at any time, either with a smaller or larger size. CS33EB costs about 2 times more than Chinese saws with similar characteristics, but it’s worth it, after all, the quality, reliability and ergonomics of Hitachi are significantly higher than “Noname” products from the Middle Kingdom.

Service

To increase the service life, you must adhere to the operating rules. The model is equipped with a two-stroke gasoline engine, which is demanding on the quality of fuel and oil. Under no circumstances should you use pure gasoline, as this will inevitably lead to breakdowns. It must be a fuel mixture of 89-octane gasoline and synthetic oil of the highest quality (50:1 ratio).

Before using the tool, you need to let it warm up for 3-5 minutes. This will reduce the likelihood of breakdown several times. It is not recommended to subject a new saw to increased loads for the first 10-12 hours of operation in order to give the new parts time to get used to it.
