  • 09/06/2019 Found tool in an unusable state. Blade tracking was completely out, blade falling off back of wheels. Guide bearings were also mis-adjusted - blade was being forced into them and making a very angry noise when pulled through by hand. Spent 45 minutes re-adjusting the blade tracking to get the blade running true again, re-adjusted blade tension and guide bearings. Alfie
