Changing The Grinding Wheels - Craftex CX Series Manual

Changing The Grinding Wheels

Because of normal wear and tear through
regular usage the grinding wheels will need
to be changed occasionally.
1.) Switch the on/off switch to the off position and
remove machine from its power source.
2.) Move the eye shield up and out of the way to
better access the tool rest.
3.) Loosen then tool rest knob and move the tool
rest away from the grinding wheel.
4.) Unfasten and remove the wheel covers by
removing the fasteners holding them securely
in place.
5.) Carefully use a wooden wedge to push gently
between the grinding wheel and the guard to
keep the shaft from turning. Now use a wrench
to remove the arbor hex nut.
There is a right and left arbor hex nut. The
left hand threaded and can be loosened by
turning it clockwise and the right hand
threaded hex nut can be loosened by
turning it counter clockwise.
Note:
6.) Take off the outer wheel flange (H) and
then remove the grinding wheel (I) from the
arbor shaft (G).
CAUTION!!!
The replacement grinding wheel should have
a rating for a higher RPM then the grinders
motor. The replacement grinding wheel must
have an outer diameter of 8" with a 5/8" bore
for the arbor shaft like the original grinding
wheels. Always keep the labels located on
the sides of the grinding wheel intact. Do Not
remove the labels as they are made of fiber
and help to distribute the holding pressure of
the tightened nuts on the grinding wheel
flanges.
7.) Replace the grinding wheel and outer
wheel flange and then tighten the arbor
hex nut to firmly secure the grinding disc in
place. Pay close attention to the thread
direction of the arbor.
CAUTION!!!
Be careful not to over tighten the arbor hex
nut as this could possibly damage the
grinding wheel, wheel flanges, and increase
the risk of serious personal injury.
8.) Put the wheel covers back into place and
make sure they are firmly secured using
the fasteners removed in step 4.
9.) Plug the machine back in to its power
supply and move the on/off switch to the
on position. Allow for the grinding wheels
to reach full operating speed and observe
the wheels to insure they are rotating
properly.
