Hitachi CJ90VST - electric jigsaw. Price, reviews, technical specifications, instruction

The manual tool usually does not allow to receive a qualitative enough result in processing operations. Especially if the work concerns metal or hard plastics. But the electric jigsaw is an exception. Thanks to the ergonomic design, high power and the means for adjusting the revolutions, the modern models of this apparatus make it possible to form a neat cut in a matter of minutes. For universal needs, the Hitachi CJ90VST electric jigsaw is the best fit, equipped with a good power reserve, a reliable housing and a basic modern option.

General information about the model

The device occupies a central place in the line of jigsaws Hitachi. Developers sought to equip the device with a balanced combination of performance and ease of use. In many respects it was possible, because the model provides good performance indicators. For example, the depth of cut in wood can be 9 cm, and the Hitachi CJ90VST steel sheets cut with a 0.8 cm immersion. For comparison, some professional tools from direct competitors of the Japanese brand provide a depth of metal cutting at a level of 0.6 cm.

Since the model is calculated as a household and universal, its price level is quite accessible to most interested consumers - on average, the cost varies from 4 to 5 thousand rubles. A lot of attention in the design of the device is given to ergonomic properties. A comfortable grip is provided with a special coating from the vibrating waves, and in the case itself materials for noise cancellation were used. The creators of Hitachi CJ90VST paid special attention to reliability. In this part, it is necessary to note the cast sole made of aluminum with nickel processing, which not only acts as a stable support, but also protects the base of the jigsaw from damage.

Specifications

The main technical and operational parameters of the device look rather modest - even against the background of models from less well-known brands. Nevertheless, during the work of Hitachi CJ90VST reveals its stuffing from the best sides, connecting and ergonomic advantages. The main technical characteristics of the Japanese electric jaw look like this:

  • Jigsaw type - with pendulum stroke.
  • The working step is 20 mm.
  • Power capacity - 705 W
  • Speed of operation - the frequency range from 850 to 3000 rpm.
  • The type of the instrument handle is bracketed.
  • Adjustment of revolutions - is provided.
  • Weight - 2.2 kg.
  • Dimensions - 21 cm in length, 6 cm in width and 21 in height.

Again, comparing the tool with other models that are positioned as universal, you can see the lack of a number of auxiliary devices and functions. In particular, the device does not have a backlight and a smooth start. But, these shortcomings are compensated by the main operating indicator of the Hitachi CJ90VST - 700W of power. Combined with a wide range of speeds and a long sawing step, the power load allows you to efficiently cope with different materials, while ensuring high speed and cut quality.

Tool Features

The greatest value for the working process is the ability to select the optimal sawing speed. In this case, there are three modes, each of which determines its pendulum parameters. In addition, the design provides a dust extraction system. For cleanliness in the workplace, a fan is responsible for cleaning the treatment line from dust and sawdust. Thanks to this option, the Hitachi CJ90VST jig saw improves visibility, which is very important for the operator. For those who care about safety, it is worth noting the availability of protection against overheating. Air cooling prevents excessive temperature glow inside the device, protecting parts from deforming processes. There is also a small addition in the form of a supporting roller, carefully guiding the working cloth without the risk of damage.

User's manual

Before working with the jig saw, it is necessary to check the reliability of the fixing of the working part, and also to make adjustments suitable for the particular type of work. The simplest is the operation to perform a straight cut. In this case, it is sufficient to produce the corresponding line and to move the tool along the guide along it. Measures for metal processing are much more complicated. In order not to have to purchase new spare parts for power tools for the replacement of cloths, worn plunger or other elements, it is necessary to follow the manufacturer's recommendations from the very beginning. First of all, adjust the sawing speed between the values "3" and "4". Further, the appropriate lubricant composition is selected. After this, you can start sawing, which is done slowly and effortlessly with pressure on the blade.

Maintenance Instructions

Most preventive measures can be performed even by an inexperienced user by visual inspection of the power tool and its accessories. The audit should start with the canvas, which is equipped with the Hitachi CJ90VST. The instruction recommends, at the slightest signs of damage to the integrity or heavy wear of the cutting element, to replace it. Also, inspect the screw fasteners. All fasteners should sit tightly in their places - loose bolts must be tightened.

In some cases, you can not do without the help of special service centers of the Japanese manufacturer. For example, the user can independently detect a malfunction in the operation of the engine or carbon brushes, but only authorized personnel can replace or repair these parts for the power tool. The same applies to the network cable.

Positive feedback on the jigsaw

The two main qualities that are allocated by almost all users are a sufficient level of power and convenience in operation. Power capacity is enough for a confident job with both wood and metal fittings. As for comfort in the process of work, it is provided by various structural and functional solutions. For example, many owners praise the possibility of quick change of saws, Hitachi speed controller CJ90VST and handle, the cover of which dampens vibrations. In addition, it is worth noting and a convenient case. Although many criticize him for large sizes, the case reliably fixes the instrument and accompanying work accessories.

Negative feedback

Most of the negative opinions about this electric jigsaw are related to the absence of a number of functional additions that are supplied to models of competing manufacturers. First of all, this refers to a soft start. In high-powered devices, this option is especially necessary, since high speed without proper monitoring can bring a lot of trouble and even spoil the workpiece. But there are also claims to the immediate function of the Hitachi CJ90VST jigsaw. The responses of some owners indicate slight deviations from the sawing line when forming a figured cut. True, such errors are also present in other jigsaws due to too fast cutting.

Conclusion

The model occupies a position in the middle segment of household electric jigsaws. However, the capabilities of this device allow us to consider it as a semi-professional tool. This status is appropriated by a considerable part of the models, which differ by a wider option. Indeed, in terms of functional content, the jigsaw of the Hitachi CJ90VST can hardly be called advanced. It does not have a smooth start, backlight, accidental start protection and other useful additions. Otherwise, ergonomics is implemented at a very decent level - with minimal initial data, Japanese designers were able to produce a very convenient tool. But its main advantage lies in its high power. It is thanks to a combination of ergonomic advantages and power potential that the Hitachi jigsawler deserves the highest ratings.
