MY SHREDDER DOESN’T ABSORB THE BRANCHES AS WELL AS BEFORE, I HAVE TO PUSH IT, WHAT SHOULD I DO?

The shredder is provided with double cutting system, one rotor with 2 sharp blades and a crushing blade. The blade must be sharpened when the cut becomes hard (about every 20 hours of use). For sharpening, respect the user manual angle and do the sharpening by a sharpener.
