1. Position the wheel on the motor shaft with the set screw at the bottom and facing the flat side of the shaft
(Figure 5).
2. Center the wheel on the squeegee. If you are using a profiled wheel (rather than a square-edge wheel),
this centering is even more important. Tighten the wheel into place using the setscrew (Figure 5).
3. Advance the diamond wheel (IN or OUT) by turning the brass thumb-wheel (clock-wise to move away,
counter-clock-wise to move toward the blade) until the wheel almost touches the blade.
Operating Instructions:
NOTE: SQUEEGEES MUST BE CLEAN AND DRY BEFORE SHARPENING. Dirty and solvent-laden
squeegees will leave an unremovable film-deposit on the diamond wheels. Such deposits will void any
applicable warranties on the wheels. Squeegees should be left to dry/rest a minimum of 4-6 hours before
sharpening.
1. Make sure the grinding motor is OFF and move the carriage assembly slowly along the squeegee blade
. As the wheel travels across the squeegee, look for raised points along the blade(high spots). Use the
thumb wheel to adjust the diamond wheel until it just makes contact with the highest point on the blade.
2. When the wheel is just touching the highest point, set the dial gauge to "0" (Loosen the thumb screw on
the side of the gauge and turn the bezel until the pointer lines up with "0".)
3. Move the carriage assembly to the left of the squeegee. Turn on the grinding motor.
4. Move the slide assembly smoothly from left to right. (The sharpening action occurs only in this
direction.) Proceed slowly and in small increments. (1-2 inch per second speed.) DO NOT SLOW OR
PAUSE WHILE THE WHEEL IS IN CONTACT WITH THE SQUEEGEE. Move the blade smoothly back to
the left and advance the wheel three to five marks on the dial guage before repeating.
Operating Recommendations:
1. The first pass will remove very little material since you have adjusted the wheel to barely touch the
squeegee. (Note: When sharpening a squeegee for the first time, the wheel may not touch all portions of
the blade. This is due to uneven insertion of the blade in its handle--often at the point of the
tightening screws. You must take off these high spots gradually to straighten the blade.) DO NOT TRY TO
SPEED THIS PROCESS BY TAKING OFF TOO MUCH MATERIAL TOO QUICKLY. Hint: If the
sharpening wheel grabs the blade and slows or stops, you are taking off too much material at once. Back
the wheel away from the squeegee before attempting to sharpen again. This process is especially
important when sharpening a square profile blade into a shaped profile.
2. Using increments of .003-.005" (three to five graduations on the dial gauge), advance the wheel toward
the blade after every 1 or 2 passes.
3. Observe the bottom of the squeegee during sharpening When the wheel is grinding the entire length of
the squeegee, sharpening is complete. Note: If you ordered a finer (230 grit) wheel in addition to the 120
grit, use it only during the final 3-4 passes to polish the edge. Excessive use of the 230 grit wheel will
result in squeegee residue buildup on the wheel and possible over heating.
