3.2 

Tool Change

In order to change the tools, the operator must first ensure that the grinder is switched off and the 

propane tank valve is closed. The operator should then place all the pocket weights provided in the 

weight holders on either side of the variable speed drive.
Then push machine down by the handle in a controlled manner until the grinder is resting on the 

top casters. The operator then taps the tools from the outside edging to remove, and installs new 

tools by sliding the tooling outward.

Machine must only be tilted back on firm, level surface. There is danger of machine 

falling if all weights are not used and surface is not level.

3.3
