IMPORTANT!
Do not overtighten the spindle hex nut, because this may cause the wheel to crack. CAUTION! DO NOT INSTALL OR USE A DAMAGED GRIND
-
ING WHEEL. The force of rotation may cause a damaged wheel to fly apart, and could injure operators or bystanders (see figure V).
Tool Rest Adjustments and Installation
Mount the tool rests to the work rest bracket using the two hex screws and washers (see Fig VI).
Before tightening the bolts, adjust the gap between the grinding wheel and the work rest to a maximum of 1/8” (3.2 mm). Tighten securely.
Adjustments
To prevent the workpiece from being pulled and caught between the tool rest and the wheel, readjust the tool rest position whenever necessary to maintain
the 1/8” (3.2 mm) distance.
1. Loosen, but do not remove, the two hex nuts holding the tool rest arm.
2. Slide the tool rest in or out to achieve a 1/8” (3.2 mm) distance from the grinding wheel surface.
3. Re-tighten the two hex nuts.
Using Your Bench Grinder
This
Bench Grinder is ideal for use in sharpening chisels, axes and other wood-cutting tools. It is also useful for repairing tips on screwdrivers
and drill bits or
for removing excess metal burrs from pieces of cut metal.
With the proper accessories, this tool can be used for cleaning metal surfaces using a wire brush or for buffing and polishing using a cloth wheel.
ON/OFF
The rocker ON/OFF power switch is located on the front of the grinder.
1. Press the side marked ON to turn the grinder on.
2. Press the side marked OFF to turn the grinder off.
Grinding
• Adjust the tool rest to accommodate large or unusually shaped workpieces.
• Always keep the workpiece moving across the face of the grinding wheel. Grinding continuously on the same spot on the wheel will cause grooves to be worn
into the wheel. The wheel may crack or become damaged more easily, and grinding of other objects will be difficult.
• If the workpiece becomes hot, dip it into the water or oil to cool it.
• Always grind on the face of the wheel (around the diameter), NEVER on the sides. Side pressure on grinding wheels can cause cracking and damage.
• If the face of the grinding wheel is worn unevenly, becomes grooved, or is no longer smooth and flat, the wheel should be reshaped with a dressing tool (not
supplied).
• If the diameter of the grinding wheel is no longer round, the wheel should be reshaped with a dressing tool or replaced.
• If the surface of the wheel becomes loaded and dull with workpiece material, the wheel should be cleaned with a dressing tool.
• After reshaping, always readjust the tool rests and spark arrestors.
Maintenance
Maintenance Required
Frequency
1.Check power cord
Before each use.
2. Check wheels for cracks
Before each use.
3. Check moving parts for alignment and binding issues
Before each use.
4. Dress Grinding Wheels
As needed.
5. Replace Grinding Wheels (see manual section for specifics)
As needed.
6. Clean and vacuum dust from the motor housing and other grinder parts
As needed.
7. Replace work-light bulb
As needed.
Service beyond recommended maintenance on these tools should only be performed by an authorized, qualified technician.
COOLANT TRAY
When grinding, metal objects become heated quickly. It is important to keep moving the object back and forth across the face of the grinding wheel and to cool
the object frequently using the coolant tray (see VII).
WORK-LIGHT BULB REPLACEMENT
When the light bulb is worn out and will no longer work, unfasten the screws that hold the lamp cover, and then gently remove the bulb from the holder by
pushing ‘in’ and turning counter-clockwise. Contact dealer or retailer for replacement bulbs. To replace, gently push the light bulb into the socket and turn
clockwise, and then reattach the lamp cover by reversing the instructions provided above.
