ASSEMBLY & ADJUSTMENTS WORKLIGHT The bench grinder provided has a flexible work light to maximize visibility during operation. A light bulb for the flexible work light is not included. Use a 120 Volt, 40 watt or less track light bult (type R20, medium base) for the onboard lamp. Make sure the bulb does not protrude past the rim of the light’s housing. The flexible work light can be positioned in whatever direction you choose.
OPERATION SHARPENING GUIDE: SCISSORS If possible, take the scissors apart to make the sharpening operation easier and safer. Remove material only from the outside surface and work from the heavy end of the blade toward the tip. KNIVES Remove metal from both faces of most knives, working from the heavy end of the blade toward the tip. SCREWDRIVERS The end of a properly sharpened screwdriver will be a perfectly flat rectangle, perpendicular to the center line of the shank.
MAINTENANCE 4. In normal use, grinding wheels may become cracked, grooved, rounded at the edges, chipped, out of true or loaded with foreign material. Cracked wheels should be replaced IMMEDIATELY. While any of the other conditions can be remedied with a dressing tool (included), new wheels sometimes require dressing to make them round. 5. If you must replace a wheel be sure to obtain one with a safe rated speed at least as high as the “NO LOAD” RPM marked on your grinder’s nameplate.
MAINTENANCE USING A WIRE OR BUFFING WHEEL A wire or buffing wheel can be installed onto either side of the grinder as needed. More spacers are required for these types of grinding wheels, depending on the wheel’s thickness. NOTE: The first spacer should always go onto the arbor shaft, between the innermost wheel flange and the body of the grinder. If needed, a second spacer should go between the outermost wheel flange and the arbor hex nut.
