PORTABLE POWER TOOL WITH INDICATING MEANS FOR ACTUAL OPERATION PARAMETER VALUES

摘要

A portable power tool having a housing (10,22) with a rotation motor (11) for powering a working implement (19), wherein sensors (28,29,38) are provided to indicate the motor speed and the power supply, and a programmable evaluation unit (36) is arranged to compare indicated speed and pressure values with stored limit values, and to accumulate the total operation time of the power tool and compare that with preset time limits for tool service intervals, and optical information means (43-49) are provided on the housing (10,22) to indicate whether those stored limit values have been reached.
