3.6 Coupler & Tool Plate
The grinder is outfitted with a coupler and tool plate. The coupler allows for the flex of the tool
plate and smooth operation of machine. The tool plate holds the diamond tools. The couplers
attach to the tool plates and provide flex for smooth operation of the diamond tools. The tool
plate/stone holder holds the tools in place for the grinding application.
3.7 Variable Speed Drive
The variable speed drive is responsible for monitoring incoming power as well as changing
the electronic frequency to allow the motor to run at different speeds. This unit is a closed
panel that is intended to be operated only with the keypad.
3.8 Tool Change
In order to change the tools, the operator must first ensure that the grinder is switched off
and disconnected from the electrical source. Then push machine down by the handle in
a controlled manner until the grinder is resting on the top handle.* The tools are loosened
by pushing them toward center of the plate. New tools are attached by placing EG tabs in
slots and pushing them toward the outside edge of the plate. The operator then loosens
the attachment hardware holding the abrasive tools in place and re-installs with preferred
abrasive tool.
* Machine must only be tilted back on firm, level surface.
