The Mini TURBO, like all of the Arbortech products, should run smoothly and be easy to control. A lot of effort goes into making sure it is balanced and all the tolerances are correct for the application.
If it feels unbalanced or does not perform smoothly, it is an indication that something is wrong.
Possible cause: Incorrect fitting.
Solution: For instructions on fitting your Mini TURBO on an angle grinder, watch this video.
Possible cause: Spindle of grinder not true.
Solution: Check to see it is running true to the axis of the shaft. A simple test is to run the blade on the benign perimeter of the blade. If it is true, it will run smooth but if it is out of center it will tend to bounce.
Try on another grinder.
Possible cause: Grinder bearing worn.
Solution: Try on another grinder. The Power Carving Unit is the perfect grinder to enhance all Arbortech attachments.
Possible cause: Mini TURBO extension shaft not sitting firmly on the base of the spindle.
Solution: Ensure it is fully screwed to the base of the spindle. Do not use a base washer or grinder (washer or locking nut). Please refer to the fitting instructions section.
