Abstract

The present invention related to handle unit 1 for a handheld working tool 2, such as a chain saw or cutting machine. The working tool 2 comprises a drive unit 3 with an engine operating a cutting unit, such as a guide bar with saw chain or a cutting disk, being positioned at the drive units 3 front part. The handle unit 1 comprises two handgrips 6 - 7 which at normal operation of the working tool are located above the drive unit 3. The drive unit 3 is rotatably mounted to the handle unit 1 at the drive units rear part by means of a rotating mechanism 24 so that the cutting direction of the cutting unit is changed when rotating the drive unit 3 in relation to the handle unit. The handle unit 1 of the present invention is provided with a fuel tank 8 providing fuel to said drive unit 3 via the rotating mechanism 24.

Description

technical field [0001] The invention relates to a handle unit for a hand-held working tool such as a chainsaw or cutter. The machining tool comprises a drive unit with a motor which drives a cutting unit, eg a guide bar with a saw chain or a cutting disc, located in front of the drive unit. The handle unit includes two handles which are located above the drive unit during normal operation of the processing tool. The rear portion of the driving unit is rotatably mounted to the handle unit by a rotating mechanism so that the cutting direction of the cutting unit is changed when the driving unit is rotated relative to the handle unit. Background technique [0002] Hand-held working tools such as chainsaws, power cutters or power shears typically have a rear handle with controls and a front handle provided with a protective frame. Thus, the operator is able to balance the machine and guide it in an easy manner by moving the front handle. This simplifies the cutting process i...
