Using the Angle Guide to adjust the Tool Rest angle
You can use the angle guide to adjust the Tool Rest (31) to best sharpen your tools.
1) Determine the best sharpening angle for your tool. The included
angle guide has several useful angles for sharpening knives,
chisels and other hand tools.
2) To adjust the tool rest’s position, the unit has two Tool Rest
Adjusters (34). The bottom one adjusts the arm’s angle, and the
top adjusts the rest’s angle. The adjusters have two positions: In
the normal position, they adjust the tightness of the joint. If they
are pulled out, they can turn freely to go to the beginning of the
turn. They are spring loaded, so they automatically return to the
first position.
3) Place the Grinding Guide on the Grinding Wheel as shown in the
photo, using the selected grinding angle.
4) Adjust the Tool Rest (31) vertically, then push it forward against
the Grinding Guide. The edge of the Tool Rest (31) should be
within 1/16” of the grinding wheel.
5) Tighten the Tool Rest Adjusters (34) To fix the Tool Rest in place. The adjusters should not be over
tightened, as they will break.
Effective Sharpening
1) For best results, the Grinding Wheel should be turning toward the blade.
2) Hold the blade flat against the Tool Rest (31), and move it lightly against the Grinding Wheel (22)
as you move it from one side to the other. Reverse the blade, and move it again lightly against
the Grinding Wheel from side to side. Do not aggressively feed the blade into the Grinding Wheel.
Repetitive light passes on each side of the blade will produce best results.
3) After grinding the blade, use a burnisher, fine whetstone or knife steel (not included) to remove
microscopic burrs from the blade edge.
Maintenance
Dressing the Grinding Wheel
For best sharpening results, it is important to maintain the Grinding Stone in good condition. With
use the Grinding Stone will wear, and may become out of round or uneven. Dressing the Grinding Wheel
will restore its proper shape and roundness.
The stone must be dry to dress it. Pour the water out of the Grinder, and allow time for the Grinding
Wheel to thoroughly dry before dressing.
To dress the Grinding Wheel, hold a dressing tool (available separately from Harbor Freight Tools) or
a flat piece of hardened steel (not included) against the Grinding Wheel as it turns. It is important to hold
this tool firmly, and supported by the Tool Rest as you are shaping the Grinding Wheel. Slowly feed the
dressing tool or piece of steel into the Grinding Wheel, until the Grinding Wheel fully contacts the dressing
tool. The Grinding Wheel should now be even and round. Observe the Grinding Wheel spinning freely for
a few seconds to determine its condition. If necessary, continue to dress the wheel until it spins smoothly.
