Using the Bench Grinder
WARNING: The grinding wheel can fly apart and cause injury.
Grinding wheels must always be checked for cracks or imperfections . This is done with the ring test . Tap the wheel gently
near the outer rim with the handle of a screwdriver. You should hear a clear bell-like ring. If a dull thud occurs, do not use the
wheel. The wheel may be damaged and could come apart during operation.
1. Always bring the workpiece into the wheel gently, without jarring.
2. The workpiece will quickly become heated, therefore frequent quenching in water is required.
3. When grinding high speed steels such as drill and tool bits, avoid high temperature buildup as this can affect the temper of the steel.
4. For small workpieces such as drill bits or chisels, 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.
Grinding with the Flex Shaft
1. Secure the Flex Shaft into the right side Wheel Cover.
Align and insert exposed shaft into wheel cover.
2. Tighten the Flex Shaft connector nut onto the Wheel Cover making sure
not to cross thread the nut.
To insert a rotary bit into the wand end of the flex shaft:
1. Locate the Locking Port just under the directional indicator arrow on
the end of wand.
2. Turn the end of the shaft to align the shaft locking hole with locking port.
3. Use the shaft end of another bit or a small screwdriver to insert into
port and secure the shaft.
4. Insert desired bit into the 1/8 in. chuck and use provided wrench to
tighten chuck.
5. Remove tool or bit from locking port. Your wand is now ready to be used.
CAUTION: When Flex Shaft is connected the rotary bit is active whenever
the grinder is turned on. Make sure the grinding stone is not in contact
with anything that might be damaged or cause harm.
