5. Assembly Instructions
A. Mounting the Grinder to the Workbench
Before using the grinder it is essential that you first mount it to a work bench or grinding stand/pedestal.
Caution:
Bench grinders vibrate. Grinder movement
during high-speed rotation may cause injury or damage
to the workpiece or operator.
1.
Position the grinder on the workbench
2.
Mark the workbench through the two mounting holes located in
the grinder base.
3.
Drill holes in the workbench at the marks
4.
Using two long bolts, lock bolts, lock-washers and nuts (parts not
supplied) secure the grinder to the workbench as shown in
Fig.2.

B. Eye Shield Assembly
Eye shields must be installed before using this equipment.
1.
Mount the left and right shield rods to the inside of the wheel guards using the hex mounting bolts
(M6x30) provided.
2.
Once the shield rods are firmly in place, slide the shield bracket onto the shield rod.
3.
Tighten the carriage bolt, leaving it loose enough to allow the safety shield to be raised and lowered easily.
Note:
The eye shield should move freely when adjusted but stay fixed when the locking knob is tightened.

C. Installing or Changing the Grinding Wheel
1.
Use a screwdriver to loosen the wheel cover screws and push anti-clockwise to remove the wheel cover
2.
Fit an appropriately sized wrench on the spindle hex nut
3.
Loosen the wheel nut in a clockwise direction for the left side and counter-clockwise direction for the right side.
4.
Remove the outer flange and the grinding wheel. To remove the hex nut, turn the wrench and the nut until the
wrench is resting on the workbench behind the tool.
5.
Inspect the new wheel carefully to ensure that there are no cracks, chips or other damage.
6.
Wipe the flange surfaces clean and install the new wheel, flange and spindle hex nut. (never overtighten this nut to
avoid cracking the wheel.)
7. To install a new grinding wheel, reverse the above procedure.
8.
Be sure that the grinding wheel and outer flange are properly seated on the spindle shaft.
9.
Replace the wheel cover and reposition the tool rest.
Warning:
Ensure that the machine is powered down and disconnected from the mains supply before
making any changes to the grinding wheel. When using the grinder immediately following a wheel
installation/change ensure that you stand to the side of the grinder (never in front) and allow the grinder to
run for at least one minute before proceeding to use it.
Never install or use a damaged grinding wheel.
