WORKING TOOL WITH MANUAL SUPPLY Russian patent published in 2017 - IPC B25F5/02 

FIELD: tools.

SUBSTANCE: invention relates to hand tools. Hand working tool has housing (2), in which internal combustion engine (11) is arranged. Internal combustion engine (11) has cylinder (19) located in cylinder space (31) formed inside housing (2). Cylinder (19) has internal combustion engine (11) start-up modes switching preset temperature. At that, internal combustion engine (11) is made with possibility to start in "cold" start mode, if cylinder (19) temperature is below internal combustion engine (11) start-up modes switching temperature, and internal combustion engine (11) is made with possibility to start in "warm" start-up mode, if cylinder (19) temperature is above internal combustion engine (11) start-up modes switching temperature. In working tool (1) there are means to obtain data on temperature in cylinder space (31) at non-working state of internal combustion engine (11), wherein information on temperature indicates whether temperature in cylinder space (31) is above or below threshold temperature value. Means for obtaining data on temperature are arranged in working tool (1) so that temperature at means for obtaining information location point has threshold value, if in cylinder (19) there is an internal combustion engine (11) start-up modes switching temperature. Temperature in cylinder space (31) is lower than that of cylinder (19), wherein in working tool (1) there is display device (22, 22') for reading information on temperature, which is visible on housing (2) outer side.

EFFECT: technical result consists in easier hand-held tool engine start-up due to possibility of "cold" or "warm" start mode setting.
