How to true and dress the wheels

Dressing a wheel cleans and levels the front surface to
increase efficiency of operation and prevent vibration.
1. Dressing a wheel involves the use of a wheel dresser

which is not supplied with the grinder. Follow the
manufacturers instructions of the wheel dresser.

2. Adjust the tool rest to allow the front part of the wheel

dresser to fit between the tool rest and wheel.

3. Start the motor and move the dresser across the front

of the wheel a sufficient number of times until the
surface is level. It is not necessary to apply excessive
force in an attempt to dress the wheel in one pass of
the wheel dresser.

4. Adjust the tool rest so that it is no more than 1-1.5mm

from the wheel.

5. Adjust the eye shield bracket to ensure the gap between

the bracket and wheels is less than 6mm.
