OPERATING THE GRINDER

9.1

ON/OFF SWITCH - FIG. 6

Turn the grinder "on" using the switch marked "I". To

turn off, press the switch marked "O".

9.2

FIG. 7

Switch the bench grinder "OFF" and disconnect

from the power supply.

Remove the screws which secure the grinding

wheel side covers then take off covers.

Use two spanners to unlock the retaining nut.

NOTE: The grinding wheel nut has a left thread.

When fitting a new grinding wheel always check

that the stated max. grinding wheel RPM exceeds

the RPM of the bench grinder. Also check the

grinding wheel for damage such as flaws or cracks, then if the wheel appears

satisfactory, fit the new wheel to the grinder.

Remove the old wheel and replace it with the new one.

Place the flange on the spindle and tighten the spindle nut just enough to hold the

wheel firmly. Do not over tighten the nut as the wheel may become damaged. Repeat

the above to replace the opposite wheel.

Re-assemble the side covers.

Stand to one side of the grinder and switch "ON". Let the grinder operate at full speed

for approximately one minute so that any undetected cracks or flaws in the wheel will

become apparent.
