5. Assembly Instructions (continued)
D. (i) Tool Rest Assembly
1.
Mount the tool rests to the work rest bracket using the knob and washers provided.
2.
Before tightening the knob, adjust the gap between the grinding wheel and the work rest to a maximum of 1/8"
(32mm) - tighten securely.
D. (ii) Tool Rest Adjustments
In order 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" (3.2mm) distance.
1.
Loosen, but do not remove, the knob holding the tool rest arm.
2.
Slide the tool rest in or out to achieve a 1/8" (32mm) distance from the grinding wheel surface.
3.
Re-tighten the locking knob.

6. Operating Instructions
This tool is designed for sharpening chisels, axes and other wood cutting tools. It is also useful for repairing tips on
screwdrivers and drill bits and removing excess metal burrs from pieces of cut metal. With the proper accessories,
the tool can be used for cleaning metal surfaces using a wire brush or for buffing and polishing using a cloth wheel.
A. Turning the Grinder On/Off
The On/Off power switch is located on the front of the grinder.
B. Grinding Guidelines
• Adjust the tool rest to accommodate large or unusually shaped work pieces.
•
Always keep the workpiece moving across the face of the grinding wheel. Grinding continuously on the same spot
on the wheel will result in excessive wearing and grooving on the grinding surface. This in turn can lead to a greater
risk of wheel damage and reduction in grinding quality.
• If the workpiece becomes hot - dip it in 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 provided). If cannot be reshaped it should be replaced.
•
If the surface of the wheel becomes loaded or dulled with waste workpiece particles or debris the wheel should be
cleaned with a dressing tool.
•
After reshaping, always readjust the tool rests and spark arrestors.
•
When grinding metal objects can be heated quickly, keep the workpiece moving back and forth across the face of
the grinding wheel and cool the object frequently using the coolant tray
