Initial Assembly and Bench Mounting

!

Assembly and mounting must be performed with the 
sharpener unplugged!

Always unplug the sharpener before doing any work on 
it (cleaning, disc replacement, etc.)

The sharpener is delivered assembled. Carefully cut the 
cable tie that is used to compress the unit in the box

The sharpener is designed to be bench mounted.

1. When installing it on a bench, place the sharpener 
on the edge of the bench to the stop and bolt it to the 
worktop using the holes in the base.

2. Fit the handle to the grinding wheel casing by sliding  
the nut into the slot and then tightening the handle.
