6. If, during the grinding operation the motor speed noticeably decreases,
pull back the workpiece, allowing the motor to regain full speed. Restart
the grinding operation using less force.
7. Note that the workpiece can get very warm. It may be necessary to
cool a workpiece by dipping it in a coolant or in water, but do not apply
coolant or water directly to the grinding wheel.
WARNING! Never grind on the side surfaces of the wheel. Grind on the
outer edge, the face (fig 8) of the wheel only.
MAINTENANCE
DRESSING GRINDING WHEELS
Dressing a wheel cleans and levels the front surface to increase abrasive
cutting efficiency and prevent vibration due to imbalance.
1. Dressing a wheel involves the use of a wheel dresser (not supplied).
Follow the manufacturer's instructions for the wheel dresser.
2. Adjust the tool rest to allow the front part of the wheel dresser to hook
between the tool rest and wheel.
3. Start the grinder and move the dresser across the face of the wheel
a number of times until the surface is level. Applying excessive force
in an attempt to dress the wheel in one pass of the wheel dresser is
unnecessary.
4. When done, the wheel will have smaller diameter. Adjust the tool rest so
that it is no more than 1/16th of an inch (1.5 mm) from the wheel's face.
5. Adjust the spark deflector to ensure the gap between the deflector and
wheel face is less than 1/4" (6 mm).
GRINDER ADJUSTMENTS
1. During the life of the grinder, some adjustments are required to maintain
a safe working environment.
2. Always ensure:
● Eye shields are adjusted to the most comfortable and most effective
angle to suit the task at hand.
● Spark deflectors are adjusted to maintain a gap between the spark
deflector and wheel not exceeding 1/4" (6 mm) as grinding wheels wear
down.
● Tool rests are adjusted so there is never a gap of greater than 1/16"
(1.5 mm) between the wheel face and the edge of the tool rest.
CHANGING A GRINDING WHEEL
WARNING!
„ Before changing a grinding wheel, ensure the grinder is turned off and
the power plug is removed from the socket.
„ Check that the replacement wheel is rated for 3500 rpm or more.
1. Remove the spark deflector / shield mount bracket with the eyeshield by
removing bolt 1, fig 9.
2. Remove the other 2 bolts on the outside cover of the wheel guard (fig
9),
3. Remove the outside cover of the wheel guard.
