Hecht 900009 Chain sharpener manual 4mm file included

HECHT 900009 chain sharpener is a tool for easy grinding of chains at a certain angle. The set includes a file with a diameter of 4.8 mm. Working with the tool is very simple, grinding is performed directly on the saw without removing the bar and the chain. The base consists of a file holder with a guide. The holder can be used to clamp a file with the desired diameter from 4 mm to 5.5 mm. The selected angle is set on the guide and the guide is attached to the sawbar. Only the odd teeth are gradually sharpened. Then simply reverse the grinding angle and sharpen all the even teeth of the chain. This ensures that the file is guided in each tooth at the same and optimal angle. Relationship between chain pitch and file diam.
