Why is the tractor engine overloaded while chipping with my Laski LS 160?
The tractor engine might be overloaded while chipping due to several reasons: * The switching-off speed is set too high because of a wrong sensor setting for minimum speed. * A blown fuse in the regulation circuit. * A faulty control unit in the regulation circuit, requiring replacement. * A defective speed sensor, also requiring replacement.
What to do if my Laski LS 160 Chipper is showing wrong chipping or loading?
If your Laski Chipper is showing wrong chipping or loading, consider these possible causes and solutions: * **Blunt blades:** Remove and regrind the blades, or replace them if they are worn. * **Worn opposite cutting edge:** Remove and regrind the cutting edge, and set the optimal clearance between the blade and the opposite cutting edge. * **Malfunction of loading rolls:** Refer to the section addressing hydraulic problems. * **Wrong angle geometry:** Regrind according to the detailed figure of edge geometry. * **Damage/wear of loading rolls:** Requires replacement. * **Too small, dry, or rotten materials:** Mix the materials before loading. * **Loading rolls do not turn – rotor runs idle:** The sensor for turning on the loading rolls might be set up incorrectly.
