CT171 - 10” WET BENCHTOP GRINDER
SPECIFIC SAFETY INSTRUCTIONS
ALWAYS read and understand the
user manual before operating the
grinder.
MAKE SURE you are wearing safety
glasses while operating the grinder.
The small particles becoming airborne
during grinding operation can seriously
damage your eyes.
ALWAYS wear a dust mask or a
respirator while grinding. The dust
produced during grinding process can
lead to serious respiratory problems if
inhaled.
MAKE SURE before making any
adjustments, servicing or installing
parts, the switch is in the “OFF”
position, and the cord is un-plugged
from the power source.
MAKE SURE the RPM of the wheel
you are installing on the grinder is
equal to or higher than the speed of
the grinder. Operating wheels at a
higher speed than rated for may cause
the wheel to lie apart, fly or break.
MAKE SURE to keep your hands at a
safe distance from the wheel.
NEVER LEAVE the grinder unattended
while it is running.
MAKE SURE to do a test on the
grinding wheels before installation.
Wheels that do not pass the test are not
safe to use. See page-8 for details.
ALWAYS stand to the side of the
grinder when turning it ON and let the
wheel reach full speed. Stand at least
one minute to the side of the grinder
after startup. A damaged wheel can
break apart and fly shortly after starting
the grinder.
DO NOT grind on the side of the wheel,
unless the wheel is rated for side
grinding.
ALWAYS keep the tool rest within 1/8”
distance from the wheel while operating
the grinder.
MAKE SURE you have read and
understood all the safety instructions in
the manual and you are familiar with
your grinder, before operating it. If you
fail to follow the instructions given in this
user manual, serious injury could occur.
WARNING
The safety instructions given above can not be complete because the environment in

PHYSICAL FEATURES

PROPER GROUNDING
Grounding provides a path of least
resistance for electric current to reduce the
risk of electric shock.
Make sure the cord is plugged into a
properly installed and grounded power
outlet. To prevent electrical hazards, have a
qualified electrician ensure that the line is
properly wired.
Make sure that the appliance is connected
to an outlet having the same configuration
as the plug. If an adaptor plug is used, it
must be attached to the metal screw of the
receptacle.
It is strongly recommended not to use
extension cords with your CT171. Always
try to position your machine close to the
power source so that you do not need to
use extension cords.
In case if you really find it necessary to use
an extension cord, make sure the extension
cord does not exceed 50-feet in length and
the cord is 14-gauge to prevent motor
damage.
WARNING
Improper connection of the equipmentgrounding conductor can result in a risk
of electric shock. Check with a qualified
electrician if you are in doubt as to
whether the outlet is properly grounded.

UNPACKING
The machine is properly packaged and
shipped completely in carton for safe
transportation. When unpacking, carefully
inspect the carton and ensure that nothing
has been damaged during transit. Open the
carton and check that the grinder and the
parts are in good condition.
While doing inventory, if you can not find
any part, check if the part is already
installed on the machine. Some of the parts
come preassembled with the machine
because of shipping purposes.
GRINDING WHEEL
The CT171 comes with a 10” diameter, 220
grit aluminum oxide grinding wheel. The
grinding wheel should be inspected
properly before installation.
Clean the dust and/or dirt from the surface
of the wheel and inspect it for any cracks,
dents, chips, or any kind of external
damage.
To inspect the wheel for any internal
damages:
Take the wheel up with a finger through the
hole located in the middle of the wheel and
tap it using a wooden mallet or a light non
metallic object as shown in figure-2.
WARNING
Tapping the wheel with heavy or metallic
objects can damage the grinding wheel.
Figure-2 Tapping locations on the grinding
stone when inspecting for internal damage
Tapping the wheel with the mallet will
create a sound, based on which you will be
able to know if the wheel is damaged or
not.
If the wheel is undamaged, the sound
omitted will have a clear or “ping” sound. If
the wheel is damaged the sound will have
no clear tone.
GRINDING SURFACE
The grinding surface of the wheel should be
parallel with the universal support.
Make sure the switch is in the OFF position
and the cord is disconnected from the
power source.
Lower the universal support 1/8” above the
grinding wheel and check if the grinding
surface of the wheel is parallel to the
universal support by rotating the wheel
slowly with your hands.

WATER RESERVOIR
The CT171 is a wet grinder and is equipped
with a water reservoir. Do no attempt to
perform grinding on this machine without
water. If the grinder is used without water, it
will either damage the grinding wheel or the
tool you are grinding.
The water reservoir is equipped with
mounting tabs used to hook to the slots on
the grinder body.
Figure-3 Checking the grinder wheel
surface parallelism with universal support
TEST RUN
Once you have assembled and inspected
the machine it is then time to do a test run
and see if the machine powers up and runs
properly.
All the tools and objects used for
assembling the machine should be
removed and cleared away during test run.
The water reservoir can be attached to the
lower slots of the grinder body when the
grinder is not in use while it is attached to
the upper slots, (filled with clean water)
when in use.
Make sure not to keep the grinding wheel
inside the water when the grinder is not
used for a long period of time. Failure to do
so, can cause the wheel become
unbalanced and break off easily while
grinding. The reservoir should be emptied
and attached to the lower mounting slots
when the grinder is not used.
Connect the machine to the correct power
source and start the machine. During the
test run if there is any unusual noise or
vibration, disconnect the machine from the
power source immediately. Check all the
parts you have assembled, once again and
try to find out the problem.
During the test run make sure the start/stop
button and all the safety features on the
grinder are working properly.
WARNING
Figure-4 Installing the water reservoir
Do not make any adjustments while the
machine is running. Turn the machine
OFF and un-plug from the power source
before making any adjustments. Failure to
do so may cause serious personal injury.

UNIVERSAL SUPPORT
GRINDING AGAINST THE
ROTATION OF THE WHEEL
The CT171 is equipped with a universal
support which can be mounted on the
grinder in horizontal or vertical position
depending on the grinding job. The vertical
and horizontal position of the universal
support allows grinding with the hand
against the rotation of the wheel.
Grinding against the rotation of the wheel
removes a large amount of material in a
very short time and finally the result will not
be very smooth. Coarse tools are
sharpened against the rotation of the wheel.
GRINDING WITH THE ROTATION
OF THE WHEEL
Turn the switch to OFF position and make
sure the cord is unplugged from the power
source.
Grinding with the rotation of the wheel
removes small amount of material and
provides a smooth result. This method is
used for blades, chisels, knives, etc...
To set the universal support for grinding
with the rotation of the wheel:
To set the universal support for grinding
against the rotation of the wheel:
Install the universal support through the
vertical mounts on the grinder and secure it
by tightening the knobs properly as shown
in figure-6.
Turn the switch to OFF position and make
sure the cord is unplugged from the power
source.
Install the universal support through the
horizontal mounts on the grinder and
secure it by tightening the knobs properly
as shown in figure-5.

ANGLE GUIDE
Your CT171 grinder comes with an angle
guide allowing you to find the cutting angle
of your tools.
Using the angle guide is simple and easy. It
features 2 angle measuring notches on
each side.
Figure-8 Using angle guide
Adjust the universal support or the tool so
that the sharpened edge of the tool is flat
against the grinding wheel and the angle
guide.
Figure-7 Angle guide measuring notches
HONING COMPOUND
To find the cutting angle on your tool using
angle guide:
Place the sharpened edge of the tool into
each measuring notches and find the notch
best fits the tool you want to grind.
Position the angle guide on the grinding
wheel with the side having the best fit
measuring notch as shown in figure-8.
The CT171 comes with honing compound
used on the leather honing wheel to give
smooth and razor sharp edge results when
sharpening tools.
Make sure the switch is in the OFF position
and the cord is disconnected from the
power sourc.
First, apply a light coat of machine oil on
the leather honing wheel and then apply a
thin coat of the abrasive honing paste.
Spread the paste on the wheel properly
with your hand.
