Adjusting Screw (22).  See FIGURE 7.

3.

Use two wrenches (not included) to loosen the Grinding Wheel (20) from the
assembly as shown in FIGURE 8.  Note: The assembly is reverse threaded so

INSPECTION, MAINTENANCE, AND CLEANING

1.

        WARNING!  Make sure the Switch (5) of the Sharpener is in its “OFF” posi-
tion and that the tool is unplugged from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.

2.

BEFORE EACH USE, inspect the general condition of the Sharpener.  Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, and any other condition that may affect its safe opera-
tion.  If abnormal noise or vibration occurs, have the problem corrected by a
qualified technician before further use.  Do not use damaged equipment.

3.

Wipe down the unit with a lint free cloth.
