The electrofret saw – popular hand tool by means of which it is possible to perform set of various works connected with cut of sheet materials. Thanks to the universal opportunities and simplicity of operation, this device is irreplaceable not only in household use, but also when performing professional tasks.
Instruction
1. Pay attention to electric motor power. The class of the tool which can be used in life depends on this indicator or intend for professional works. Household models have the power of 380-700 W, can saw tree up to 0.7 cm thick, steel – to 0.2-0.4 cm. Household differ from professional devices in set of additional functions and smaller working resource.
2. The device of professional level has power from 750 to 1000 W, provides the steel machine cut to 1 cm and two-centimetric aluminum. Depth of cut of wood reaches 0.8-1.5 cm. In the instruction material thickness are specified as "the maximum depth has drunk".
3. Also in the market of hand tool it is possible to meet low-power models which eat from the storage battery. They are suitable for the material machine cut in limited volume in the absence of the power supply network.
4. Take an interest what frequency of the course of fret cloth at the device. This parameter indicates number of reciprocating motions of the cutting cloth in minute and determines the speed of operation of the tool. It should be noted that steel is better cut with smaller frequency of the course, tree – at bigger.
5. Adjustment of frequency of the course, depending on tool model, can be carried out before turning on of the tool, or by means of the fixing button directly in the course of work. Consider that the frequency of the course is higher and performance is higher, the file cloth wears out quicker.
6. Make sure available of the device of the pendular mechanism with the switch. The mechanism makes movements by file in the horizontal plane, increasing the cutting performance, time of operation and speed of work. Essential minus is some decline in quality of the machine cut. Therefore if necessary to execute the fair machine cut switch-off the mechanism. This function is irreplaceable when cutting wood of strong breeds and steel.
