USING THE GRINDER
WARNING
!
The grinding wheelcan fly apart and cause injury. Grindingwheels must always be checked for
cracked for cracks or imperfections. This is done with the "ringtest". Tap the wheelgently near
the outer rim with the handle of a screwdriver. You should heara clear bell-like ring. If a dull thud
occurs, do not use the wheel. The wheel maybe damaged and could come apart duringoperation.
CAUTION: Always wear ANSI-approved safetyglasses when grinding.
1. Always bring the workpiece into the wheelgently, without jarring.
2. The workpiece will quickly become heated; therefore, frequent quenching in water is required.
3. When grindinghigh speed steels such as drilland tool bits,avoid high temperature buildup as
this can affect the temper ofthe steel.
4. For smallworkpieces such as drill bits orchisels, avoid applying pressure to the wheel at a high
angle that could cause the workpiece to become lodged between the tool rest and the wheel.
5. When usingthe Flexible Shaft, be sure the Grinder is turned OFF and wait for it to stop before
setting down the Flexible Shaft.
MAINTENANCE
Dressing the GrindingWheel
Note: New wheels frequentlyare not true and during operation will often become grooved, glazed
(build up), out of round, ormisshapen. You will need a grinding wheel dresser for this operation.
1. Stand tothe side ofthe wheel for this operation.
2. If the wheel is newlet it run for a minute with no load. If the wheel runs straight and true you will
not need todress it priorto operation. Ifit dose not, proceed with the following instructions.
3. If you are using a "pistol grip" dresser, grip the handle firmly with one hand and the arm oft
he dresser with the other. Allow the wheelto reach fullspeed. Use the tool rest to support your
hand and the dresser, and evenly applythe dresser to all surfaces ofthe wheel. The wheel can be
dressed in a few minutes.
4. If you are using an "inline" dresser, hold the handle firmly, put the dresser on the tool test so
that its wheels can move freely (i.e., the exposed part ofthe wheel should be facing up ). Let the
wheel reach fullspeed and applythe dresser evenly to allsurfaces.
