Lubrication
Mastercraft
®
tools are properly lubricated at the factory,
and are ready to use. If abnormal noise or vibration
occurs, turn the sharpener off immediately, and correct the
problem before further use.
General maintenance
before each use, examine the general condition of the
sharpener, the switch, the power cord, and the extension
cord. Check for loose screws, jamming, improper mounting,
broken parts, and any other condition that may affect the
safe operation of the wet/dry sharpener. Do not operate the sharpener if a sharpening wheel is chipped or
damaged. Do not use a damaged sharpener.
Cleaning
Empty the water from the water reservoir after each use,
and before storing the wet/dry sharpener.
Use a dry, clean rag to clean and dry all areas of the
wet/dry sharpener. Do not use solvents or other harsh
chemicals for cleaning, because they are harmful to plastic
and other insulated parts. Petroleum-based products, brake
fluid, thinners and ammonia-based detergents are also
harmful.
Reshaping the dry wheel (Fig.15)
With use, abrasive sharpening wheels get dull, worn and lose their shape. A misshapen wheel will not grind
or sharpen properly. The proper use of a dressing wheel can extend the life of the dry wheel.
1. Verify that the dry wheel tool rest is properly adjusted, and that there is a distance of approximately
1/16” (1.6 mm) between the tool rest and the dry wheel. Verify that the eye shield is properly
positioned.
2. Place the dressing wheel (1) on the tool rest (2) but do not allow it to touch the dry wheel.
3. Turn the sharpener on and allow it to run for approximately 1 minute.
4. Move the dressing wheel forward slowly until it touches the highest point on the face of the wheel.
5. Dress the wheel by slowly moving the dressing wheel from side to side on the tool rest. Continue to
move the dressing wheel over the face of the dry wheel until the surface of the dry wheel is clean and
smooth, the edges are square, and the dry wheel is round.
MAINTENANCE
NOTE:
After reshaping the wheel, and before using the sharpener, re-adjust the tool rest
so that there is a distance of approximately 1/16” (1.6 mm) between the tool rest
and the dry wheel, and position the eye shield properly.
MAINTENANCE
Changing the dry wheel (Fig. 16-18)
1. Unplug the sharpener from the power source.
2. Move the tool rests and the eye shield to their lowest
positions.
3. Turn the sharpener over, and place it on a stable work
surface.
4. Remove the six screws (Fig. 16) that hold the cover to
the housing.
5. Place the sharpener upright on the work surface. Lift
the cover off.
6. Apply pressure to the two plastic clips that hold the dry
wheel compartment (1) to the housing (2), and slide
the compartment down and away from the housing.
7. Place the wrench (included) (4) on the motor shaft,
and then place another wrench (not included) (5) on
the large nut (6) that is located at the wheel end of the
shaft.
8. Loosen and remove the large nut (6) by turning it
counterclockwise while holding the motor shaft steady
with the small wrench.
9. Remove the outer flange (7) and dry wheel (3) from the
motor shaft.
10. Place a new dry wheel on the motor shaft, replace the
flange and the nut, and tighten the nut.
11. Put the dry wheel compartment back in place. Verify
that the clips hold it securely to the housing.
12. Put the cover on the housing , turn the sharpener over,
and re-install the six screws.
Changing the wet wheel (Fig.16, 19 and 20)
1. Unplug the sharpener from the power source.
2. Move the tool rests and the eye shield to their lowest
positions.
3. Turn the sharpener over, and place it on a stable work
surface.
4. Remove the six screws (Fig. 16) that hold the cover to the housing.
5. Place the sharpener upright on the work surface and lift the cover off.
