Circular saws cutting material with disk equipment are in high demand both in production and in private households. The demand for this tool is due to the possibility of deep direct cut. One of the most prominent representatives of this segment is the Bosch GKS 190 Professional model, combining innovative functionality, decent performance and ergonomics typical of amateur technology.
Model Overview
The German manufacturer presents a power tool in the form of a circular saw, which can be used in construction, furniture manufacturing, in the manufacture of copyright products from wood material and in equipping household sawmills. The functional and power capabilities of the device allow you to perform high-quality cutting under any conditions. It is important to emphasize that we are talking specifically about a hand-held circular saw on wood, which expands the range of tasks. Another thing is that stationary models of the same class are more productive and easier to cope with stream cutting of workpieces.
The design of the model is traditional - the base is formed by a support platform with adjustment levers, a protective casing and an electric motor. As for the external description of the Bosch GKS 190 circular saw, the tool differs in compact dimensions, the presence of tenacious overlays for holding the case and transporting. The operator in the cutting process will deal with a rubberized insulated handle, mode switches and devices that facilitate the control of the working process (guides, marking scale, clamping mechanisms). A parallel emphasis is intended for convenient location, and an external pipe for connecting a construction vacuum cleaner is responsible for operative dust removal.
Specifications
The model refers to professional technology, as evidenced by the corresponding marking of the case in blue. However, the developers did not chase record performance in the class and emphasized the balanced characteristics of the Bosch GKS 190 circular saw, which are presented below:
- Power tool - 1400 watts.
- The spindle frequency is 5500 rpm.
- The diameter of the cutting tool is 19 cm.
- The diameter of the hole for landing the disc is 3 cm.
- Tooling immersion depth at 90 ° - 7 cm.
- Depth of cut at 45 ° - 5 cm.
- Weight - 4.2 kg.
- The length of the power cord is 4 m.
- Dimensions of the structure - 393x264x282 mm.
It is also worth highlighting the wide configuration of the model, which rarely happens in the families of premium manufacturers. In the basic equipment, the GKS 190 circular saw from Bosch received a carbide wheel, a key for changing accessories, an emphasis and an adapter for connecting a vacuum cleaner.
Model Features
With a fairly average power, the device turned out to be universal in terms of various cutting configurations. In particular, a wide range of cut angles is noted by many. At the same time, the performance of the Bosch circular saw is not so small - if you calculate the number of watts per 1 kg of mass, the model will have few direct competitors. Especially when you consider the combination of functionality with the settings of the operating parameters.
Among the new technological capabilities, it is possible to note the already mentioned option of connecting the dust extraction, spindle lock, as well as a number of design solutions like a marking system and an aluminum protective casing. On the other hand, the Bosch GKS 190 circular saw did not receive speed control, a soft start function and support for stable operation at extremely high load. These are significant flaws for non-professional users, who put ergonomics and safety of operation of such equipment in the first place.
Saw instruction manual
It is possible to complete the tool only with a saw blade of a suitable format - preferably of the Bosch brand. Before starting work, it is necessary to check the technical and functional state of the apparatus design, its electrical wiring and the reliability of the fastenings of individual parts. As noted in the instructions for the Bosch GKS 190 circular saw, the setting for the depth of cut must correspond to the thickness of the workpiece. At a minimum, the teeth of the disc should not protrude beyond the workpiece to its full height. Adjustment by the angle of cut is carried out with the help of thumb screws, which are first loosened, making it possible to adjust the position of the disk, and then are again fixed in a new position.
In the process, the tool should be run evenly, without jerking and with moderate feed along the contour. The guides of the Bosch GKS 190 circular saw will help to maintain accuracy of a cut even when processing hardwoods. For quality cuts along the edge, a parallel stop is recommended. It can be used to cut pieces of material of equal size. Turn off the equipment only when the saw blade is released from the workpiece.
Maintenance Instructions
Performing any technical manipulations with this tool, its plug must be disconnected from the outlet. After each application session, the ventilation slots should be cleaned - the quality of the functioning of the engine and the nodes adjacent to it depends on them. It is recommended to remove chips and dust from hard-to-reach places of the housing with a stream of compressed air from the compressor or with a brush. The reliability of the installation of the protective cover is periodically checked. This part ensures the safety of the operator, so its travel and fastening must be in optimal condition. Bosch GKS 190 circular saw accessories must be protected against corrosion during long-term storage. The best way to protect yourself is to easily treat the film with an acid-free oil. However, this layer must be removed before the working process, otherwise traces of chemical treatment will remain on the surface of the workpiece. In addition, the resin and all kinds of impregnations on the metal disk adversely affect its function.
Instrument Safety
Since this is a power tool that works with hazardous equipment, it is necessary to follow strict safety rules. The basic requirements are as follows:
- Both the disk and the protective devices of the case must be in good condition and in good condition - without the slightest cracks or other damage.
- Before work, the workpieces should also be checked for suitability for cutting. The tool manufacturer strongly discourages working with parts that contain knots and nails.
- It is also not recommended to use discs marked with HSS, which are designed for high speeds.
- If the Bosch circular saw enters the wedge, it must be stopped immediately by releasing the start switch. It will be possible to continue work after releasing the saw blade and checking its condition.
- During operation, it is forbidden to allow any contacts and approximations of up to 15-20 cm to the cutting disc.
- The operator must use personal protective equipment - for example, construction headphones and a mask with a respirator.
Positive feedback about the model
The owners of the tool characterize it from the best sides, noting the reliability, ease of physical handling and sufficient power potential to perform most typical cuts. In particular, stable quality machining of timber and boards with a thickness of 10 cm and logs with a diameter of 15 cm is indicated. But a good result will be achieved only if sawing is not quick, but evenly on both sides. The small ergonomic advantages of Bosch GKS 190 Professional are also noted, among which a long cable of 4 m, the presence of an aluminum casing and an ergonomically thought-out design of the structure that is felt during operation.
Negative model reviews
There is a lot of criticism regarding the power, which could be higher, since the tool is positioned as a professional and also costs a lot - about 8 thousand rubles. If a technician performs single complex cuts qualitatively with a competent and thorough approach of the master, then serial processing, which requires endurance, is beyond the power of this model. At the same time, many point to the functional limitations of the Bosch GKS 190 circular saw. Reviews suggest that balanced performance and ergonomics orientate the model to use in the workshop for solving non-standard tasks, but, for example, the absence of a laser pointer and soft start reduces the value of such a tool application.
Conclusion
Bosch has always been famous for its original approach to the development of tools, which allowed it to set the fashion and the main trends in different segments of the production of construction equipment. In this case, a model with a typical set of capabilities and averaged characteristics is considered. Who should use the GKS 190 hand-held circular saw for wood, given the high cost and very tangible operational limitations? This is a worthy choice for an experienced craftsman who does not need auxiliary functions and who does not face the task of in-line processing of lumber. The structural advantages, coupled with the reliability and accuracy of the cut, make this modification a good choice for an author's workshop or for use in a private economy by an experienced carpenter.
