CHANGING ACCESSORIES
TURN OFF AND UNPLUG THE BENCH GRINDER. USE ONLY GRINDING
WHEELS THAT MEASURE 6 INCHES IN DIAMETER FOR MODE BGC-6 AND
8 INCHES IN DIAMETER FOR MODEL BGC-8. MODEL BGC-6 HAS 1/2 INCH
ARBORS ON BOTH SIDES. MODEL BGC-8 HAS 5/8 INCH ARBORS ON BOTH
SIDES.
Follow the steps presented below to remove and replace an accessory:
1. Raise the eye shield up, out of the way.
2. Loosen and pull the tool rest out as far as possible. Do not remove it.
3. Loosen and pull the spark guard out as far as possible. Do not remove it.
4. Remove the five screws from the left side wheel cover and remove the cover.
5. Insert a flat bladed screwdriver into the slot in the left end of the grinder rotor
shaft. Hold the screwdriver firmly to keep the shaft from turning as you loosen
and remove the hex nut in the center of the grinding wheel or other accessory.
NOTE: If you are changing only the right side accessory, you still need to remove
the left wheel cover. It may be necessary to strike the wrench sharply in the
loosening direction with the heel of your hand to loosen the nut.
NOTE: The nut on the right side of the grinder has a standard right hand thread
turn counter-clockwise to loosen). The one on the left side has a left hand thread
(turn clockwise to loosen).
6. Remove the wheel washer and the wheel.
7. Inspect the wheel for cracks, chips or any other visible damage (other than
normal wear) and discard if such damage is found. Inspect the blotter for
damage. If the blotter is missing or severely damaged, replace it with a piece of
thin cardboard or blotter paper cut in the same shape. NEVER USE A GRIND-
ING WHEEL WITHOUT A BLOTTER.
8. Install the new wheel or other accessory. Be sure that both wheel washers are in
place (concave sides toward wheel). See Figure 6.
9. Hold as before and tighten the nut firmly but do not overtighten.
OVERTIGHTENING CAN CRACK A GRINDING WHEEL.
10. Replace the wheel cover and its five screws.
11. Adjust the tool rest to 1/8" from the accessory and tighten securely.
12. Adjust the eye shield to a point between your eyes and the accessory.
