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 1.5mm from the wheel (See Fig 6).
5) Adjust the spark deflector to ensure the gap between the deflector and wheel is no more than
5mm
(See Fig 7).
9. Grinder adjustments
During the life of the grinder some adjustments are required to maintain a safe working environ-
ment. Please ensure the following:
1) Always adjust the eye shields to the most comfortable and most effective angle to suit the task
being performed.
2) As the wheels wear, the spark deflector must be adjusted to ensure the gap between the spark
deflector and wheel does not exceed 5mm.
3) As the wheels wear the tool rests must also be adjusted so there in never a gap of greater than
1.5mm between the wheel and the edge of the tool rest.
10. Changing a grinding wheel
Warning: Prior to changing a wheel, ensure the grinder is turned off and the power plug is remo-
ved from the socket. Make sure that the replacement wheel is rated at 3000/min or higher.
