A hand tool usually does not allow to obtain a sufficiently high-quality result in processing operations. Especially if the work concerns metal or hard plastics. But the jigsaw is an exception. Thanks to the ergonomic design, high power and speed control, modern models of this device allow you to create a neat cut in minutes. For universal needs, the Hitachi CJ90VST jigsaw is optimally equipped with a good power reserve, a reliable case and a basic modern option.
Model Overview
The device occupies a central place in the Hitachi line of jigsaws. The developers sought to give the device a balanced combination of performance and ease of use. This was largely possible, as the model provides good performance. For example, the depth of cut in wood can be 9 cm, and Hitachi CJ90VST cuts steel sheets with immersion of 0.8 cm. For comparison, some professional tools from direct competitors of the Japanese brand provide a metal cut depth of 0.6 cm.
Since the model is calculated as 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. The convenient handle is provided with a special coating from vibration waves, and materials for noise reduction were used in the case itself. The creators of Hitachi CJ90VST paid special attention to reliability. In this part, it should be noted cast aluminum sole with nickel treatment, which not only acts as a stable support, but also protects the jigsaw base from damage.
Specifications
The main technical and operational parameters of the device look quite modest - even against the background of models from lesser-known brands. Nevertheless, in the process, Hitachi CJ90VST reveals its filling from the best sides, connecting ergonomic advantages. The main technical characteristics of the Japanese jigsaw are as follows:
- Jigsaw type - with pendulum stroke.
- The stroke of the working step is 20 mm.
- Power potential - 705 W
- Speed - frequency range from 850 to 3,000 rpm.
- Type of tool handle is staple-shaped.
- Speed setting - 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 notice the absence 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 Hitachi CJ90VST - 700 watts of power. Together with a wide speed range and a long saw pitch, the power load allows you to effectively cope with different materials, while ensuring high speed and quality of the cut.
Tool Features
Of greatest importance to the workflow is the ability to select the optimal sawing speed. In this case, three modes are provided, each of which determines its own parameters of the pendulum stroke. In addition, the design provides a dust removal system. The fan, which cleans the processing line from dust and sawdust, is responsible for cleanliness at the workplace. Thanks to this option, the Hitachi CJ90VST jigsaw improves visibility, which is very important for the operator. For those who care about safety, it is worth noting the presence of protection against overheating. Air cooling prevents excessive heat build-up inside the unit, protecting parts from deforming processes. A small addition is also provided in the form of a support roller, which accurately guides the work blade without the risk of damage.
User's manual
Before starting work with a jigsaw, it is necessary to check the reliability of the fixation of the working part, as well as make settings suitable for a particular type of work. The simplest is the operation to perform a direct cut. In this case, it is enough to draw the corresponding line and move the tool along it strictly along the guide. It is much more difficult to implement measures for metal processing. In order not to have to buy new spare parts for a power tool to replace blades, a worn out plunger or other elements, it is necessary to adhere to the manufacturer's recommendations initially. First of all, you should adjust the sawing speed between the values “3” and “4”. Next, the appropriate lubricant composition is selected. After that, you can start sawing, which is performed slowly and without undue effort with pressure on the blade.
Maintenance Instructions
Most preventive measures can be performed even by an inexperienced user by visual inspection of a power tool and its components. The audit should begin with the canvas that the Hitachi CJ90VST is equipped with. The manual recommends that, at the slightest sign of integrity loss or severe wear of the cutting element, it should be replaced. You should also inspect the screw mounts. All fasteners should fit snugly in place - 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 malfunctions in the engine or carbon brushes, but only authorized personnel can replace or repair these spare parts for power tools. The same applies to the network cable.
Positive jigsaw reviews
Two main qualities that almost all users emit are a sufficient level of power and ease of use. There is enough power potential for confident work with both wood and metal fittings. As for comfort in the process, it is provided by various structural and functional solutions. For example, many owners praise the ability to quickly change files, the Hitachi CJ90VST speed controller and the handle, which dampens vibration. In addition, a convenient case is worth noting. Although many criticize it for its large size, the case reliably fixes the tool and related working accessories.
Negative reviews
Most of the negative opinions about this jigsaw relate to the lack of a number of functional additions, which are supplied with models of competing manufacturers. This primarily refers to a soft start. In powerful machines, this option is especially necessary, since high speed without proper control can cause a lot of trouble and even ruin the workpiece. But there are claims to the direct function of the Hitachi CJ90VST jigsaw. Reviews of some owners note slight deviations from the cut line when forming a curly cut. True, such errors also occur in other jigsaws due to too fast cuts.
Conclusion
The model occupies a position in the middle segment of household jigsaws. However, the capabilities of this device allow us to consider it as a semi-professional tool. Such a status is assigned to a considerable part of the models, which are distinguished by a wider optional. Indeed, in terms of functional content, the Hitachi CJ90VST jigsaw can hardly be called advanced. It lacks a smooth start, backlight, protection against accidental start-up 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 is high power. Thanks to a combination of ergonomic advantages and power potential, the Hitachi jigsaw deserves the highest ratings.
