CHANGING THE GRINDING WHEEL (Fig. K)
Due to normal wear, both wheels will need to be
replaced occasionally. See Fig. K.
1. Turn the power switch “OFF” and unplug the power
cord from its power source
2. Rotate the eyeshields to the “UP” position for
access to the tool rests.
3. Remove the three screws (A), flat washers (B),
external tooth lock washers (C) and nuts (D) hold-
ing the Outer Wheel Covers (E) to the Bench
Grinder
.
4. Remove the Outer Wheel Covers.
5. Place a small wooden wedge between the Abrasive
Wheel (F) and Tool Rest (G) to prevent the wheels
from rotating.
6.
Remove the right side grinding wheel by turning the
lock-nut (H) in the counterclockwise direction with
an open-end wrench (not included). The left side
wheel can be removed by turning the lock-nut in the
clockwise direction with an open-end wrench.
7. Remove the Outer Wheel Flange (I) and then
remove the abrasive wheel from the arbor shaft (J).
The
Arbor Bushing (K) should be saved, for future
use, if the replacement wheel does not use this
bushing.
8.
CAUTION: The new abrasive wheel to be put on
the Bench Grinder must have a higher R.P.M rating
than the Bench Grinder. The label on the side of the
abrasive wheels must stay on, DO NOT remove
this label.
9. Replace the abrasive wheel, outer wheel flange,
and the lock-nut in reverse order from removal.
CAUTION: DO NOT OVER-TIGHTEN the lock nut as
this may damage the abrasive wheels and cause seri-
ous injury to the operator
.
DUST PORT (Fig. N)
There is a dust port located on the inner side of each
Inner Wheel Guard. These dust ports allows the grind-
ing dust to exit the wheel cavity.
If you choose to attach the dust ports to a dust collec-
tion system, make sure the dust collector is rated and
configured for your grinding operation.
