Abstract

A hand-held power tool, more particularly a router, includes (i) a housing in which a drive unit for driving an insertion tool is disposed; (ii) a base plate for guiding the hand-held power tool on a workpiece surface, the base plate being height-adjustable on the housing, and the base plate having an opening, through which the insertion tool at least partly extends; and (iii) a height adjustment device for setting a working height of the base plate on the housing relative to the insertion tool. A setting aid is provided which allows height adjustment of a bottom of the base plate by way of the height adjustment device such that said bottom is flush with a predefined cutting edge of the insertion tool.

First claim

What is claimed is:

1 . A hand-held power tool, comprising:
a drive unit configured to drive an insertion tool; a housing in which the drive unit is arranged; a base plate configured to guide the hand-held power tool on a workpiece surface, the base plate being height-adjustable on the housing, and the base plate having an opening through which the insertion tool can at least partly extend; a height adjustment device configured to adjust a working height of the base plate on the housing relative to the insertion tool; and a setting aid configured to facilitate a height adjustment of a bottom of the base plate by way of the height adjustment device such that said bottom is flush with a predefined cutting edge of the insertion tool, wherein: the setting aid is arranged on the bottom of the base plate at least in a setting position, in which setting position of the setting aid, the height adjustment is able to take place, the setting aid has a fastening section, the bottom of the base plate includes a receptacle, the fastening section is arranged in the receptacle when the setting aid is in the setting position, and the setting aid is pivotally arranged on the bottom of the base plate via the fastening section.

2 . The hand-held power tool according to claim 1 , wherein the setting aid is cuboid or bar-shaped.

3 . The hand-held power tool according to claim 1 wherein the base plate has a top that includes a second receptacle configured to receive the fastening section when the setting aid is in an idle position in order to enable the setting aid to be arranged on the top when the setting aid is in the idle position.

4 . The hand-held power tool according to claim 1 , wherein the receptacle on the bottom of the base plate is an opening on the bottom which is configured to arrange the setting aid when the setting aid is in the setting position.

5 . The hand-held power tool according to claim 1 , wherein the hand-held power tool is a router.

6 . The hand-held power tool according to claim 1 , wherein the fastening section is arranged in the receptacle in a latching or press-fit manner when the setting aid is in the setting position.
