GENERAL SAFETY GUIDELINES
BEFORE USING THIS POWER
TOOL
• Operate in a safe work environment. Keep
your work area clean, well lit and free of
distractions.
• Keep anyone not wearing the appropriate s
afety equipment away from the work area.
• Store tools properly in a safe and dry location.
Keep tools out of the reach of children.
• Do not install or use in the presence of flam-
mable gases, dust or liquids.
• Always wear impact safety goggles that
provide front and side protection for the eyes.
Wear a full-face shield if your work creates
metal filings or wood chips. (Eye protection
equipment should comply with ANSI Z87.1
standards.)
• Wear gloves that provide protection based on
the work materials or to reduce the effects of
tool vibration.
• Non-skid footwear is recommended to main-
tain footing and balance in the workenvironment.
• Wear the appropriate rated dust mask or
respirator.
• Do not operate any tool when tired or under
the influence of drugs, alcohol or medications.
• Avoid wearing clothes or jewelry that can b-
ecome entangled with the moving parts of a
tool. Keep long hair covered or bound.
• Do not overreachwhen operating the tool.
Proper footing and balance enables better
control in unexpected situations.
• Securely hold the material using both hands.
Applying the material to the grinder with only
one hand can result in a loss of control.
• Never use a tool with a cracked or worn gri-
nding wheel. Change the grinding wheel
before using.
• Replace cracked wheel immediately. Use only
flanges supplied with the grinder.
• Clean dust and debris from beneath the gri-
nding wheels frequently.
• Do not start the tool if the grinding wheel is in
contact with the workpiece.
• Always ensure the safety guards are attached
correctly and do not operate the bench grinder
without the guards attached. Adjust the dista-
nce between the wheel and the tool rest to
maintain a 1/16 in. or less separation as the
diameter of the wheel decreases with use.
• Use an appropriate dust respirator when working
for an extended period of time. This will help
prevent breathing in the fine dust created while
grinding.
• Do not grind on the sides of grinding wheels
unless they are specifically designed for that
purpose.
• Before using the tool on the workpiece, run the
tool at the highest speed, without a load, for at
least 30 seconds in a safe position. Stop im-
mediately if there is any vibration or wobbling
that could indicate poor installation or a poorly
balanced grinding wheel.Check the tool to
determine the cause.
• Do not allow the motor to overload or overheat.
Take breaks to rest the tool.
• Do not subject the grinding wheel to any lateral
pressure as it may damage the tool or cause
it to kickback.
ADDITIONAL SPECIFIC SAFETY
RULES
1. Only use a grinding wheel with the correct arbor
size and shape that matches the grinder’s
spindle.
2. Ensure the grinding wheel has a clean edge.
Check the grinding wheel for wear or chipping
and replace if necessary.
3. Never install more than one grinding wheel at
a time unless the tool and wheels are design-
ed for that purpose.
4. A large amount of sparks will be created when
working with a grinding wheel. Hold the tool
so that sparks fly away from you and other
persons or flammable materials. Have a fully
charged fire extinguisher present.in the event
of a fire.
5. Do not subject the grinding wheel to any
lateral pressure as it may damage the
tool or cause it to kickback.

supply whenever possible. Use extension cords
or surge protectors only when the tool's power
cord cannot reach a power supply from the work
area.
25. Do not operate this tool if the power cord is fr-
ayed or damaged as an electric shock may
occur, resulting in personal injury or property
damage.
26. Inspect the tool's power cord for cracks, fraying
or other faults in the insulation or plug before
each use.
27. Discontinue use if a power cord feels more than
comfortably warm while operating the tool.
28. Keep all connections dry and off the ground to
reduce the risk of electric shock. Do not touch

DANGER!
DO NOT EXPOSETHE MACHINE TO RAIN OR
OPERATE THE MACHINE IN DAMP LOCATIONS.
THIS MACHINE MUST BE GROUNDED
WHILE IN USE TO PROTECT THE OPERATOR
All grounded, cord-connected machines: In the
event of a malfunction or breakdown,grounding
provides a path of least resistance for electric
current to reduce the risk of electric shock. This
machine is equipped with an electric cord having
an equipment grounding conductor and a gro-
unding plug.
FROM ELECTRIC SHOCK.
The plug must be plugged into a matching outlet
that is properly installed and grounded in accor-
dance with all local codes and ordinances.
Do not modify the plug provided–if it will not fit
the outlet, have the proper outlet installed by a
qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or repl-
acement of the electric cord or plug is necessary,
do not connect the equipment-grounding condu-
ctor to a live terminal.
Check with a qualified electrician or service per-
sonnel if the grounding instructions are not com-
pletely understood, or if in doubt as to whether the
machine is properly grounded.
Use only 3-wire extension cords that have 3-pronged
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown
in Fig. A.Repair or replace damaged or worn cord
immediately.

MINIMUM GAUGE FOR CORD SETS
Use proper extension cords. Make sure your extension
cord is in good condition and is a 3-wire extension
cord which has a 3-pronged grounding type plug
and matching receptacle which will accept the ma-
chine’s plug. When using an extension cord, be
sure to use one heavy enough to carry the current
of the machine. An undersized cord will cause a
drop in line voltage, resulting in loss of power and
overheating. The table shows the correct gauge
to use depending on the cord length. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

ASSEMBLY INSTRUCTIONS
The tool rest attaches to the inward side of
the guard and provides a surface that must
be used to support the workpiece during
operation.Certain types of grinding/sanding
may require jigs or accessories that will be
used with the tool rests to assure the proper
angle of the workpiece against the wheel.
Failure to install and use the tool rest can lead
to serious personal injury.
To install the tool rests:
1.Loosely attach the tool rests perpendicular
to the belt or wheel surface with the knob
bolts, 5 mm washers and hex nuts.
2.To adjust the angle of the sanding belt
tool rest, use a square or a protractor to
set the angle of the tool rest in relation
to the sanding belt.
3.Adjust both tool rests approximately 1/16
to 1/8 in. from the grinding wheel and the
sanding belt and tighten the knob bolts.
(in Fig.3）shows the correct adjustment
for the tool rest at the grinding wheel.
INSTALLATION TOOL RESTS
Figure 3
The spark guard must be installed and posi-
tioned 1/8 in. from the grinding wheel to minimize
sparks flying towards the operator. The eye
shield must be positioned between the grinding
wheel and the operator's face to protect the
operator from flying debris. This is not a rep-
lacement for safety glasses!
To install the spark guard and eye shield:
1.Using the included 5 mm screw and washer,
install the spark guard as shown(in Fig.4）.

belt on its rollers, so that it runs balanced and
does not make contact with the sides of the
belt cover.
To track the sanding belt:
1. Disconnect the machine from the power
supply.
2. Rotate the grinding wheel.
3. As you rotate the grinding wheel,watch how
the sanding belt rides on the upper roller.If
the belt is tracking properly, the sanding belt
should be centered between the sides of the
belt cover as shown (in Fig. 5).
4. While spinning the wheel, turn the tracking
control knob counterclockwise to make the
belt move to the left, or turn the tracking
control knob clockwise to make the belt move

WARNING
!
OPERATION
TLGS625
The operation of any grinder can result in
foreign objects being thrown into your eyes,
which can result in severe eye damage.
Before beginning power tool operation, always
wear safety goggles or safety glasses with
side shields and a full face shield when needed.
We recommend Wide Vision Safety Mask for
use over eyeglasses or standard safety gl-
asses with side shields.
TEST RUN
Once mounting is complete and adjustments are
done to your satisfaction, you are ready to test
the machine.
To test run the grinder/sander:
1. Plug the machine into the power source.
2. Stand to the side of the grinding wheel and
turn the grinder ON.
The machine should run smoothly with little or
no vibration or rubbing noises. Strange or un-
usual noises should be investigated and corr-
ected before operating the machine further.
If the machine seems okay, stay out of the line
of rotation of the grinding wheel and let it run for
1 to 2 minutes to make sure the wheel is stru-
cturally sound.
All grinding wheels have the potential of b-
reaking apart during operation,causing serious
personal injury or death! Always stand to the
side of the grinder when turning it ON and
wear the proper safety equipment to protect
yourself.
WARNING
!
The grinder is a safe tool when used properly.
In addition to the safety instructions in this man-
ual, the most important safety consideration is to
use common sense at all times. What may be
okay in one situation, may not be safe in another.
Read the following statements to protect yourse-
lf before grinding:
• Make sure all guards and eye shields are in
place.
BEFORE GRINDING
• Remember that grinding often produces sparks.
DO NOT allow anyone to stand in the path of the
sparks. DO NOT grind near flammable liquids or
gases.
• Wear the proper protective clothing. Remember
that particles flying off of a grinding wheel will be
traveling very fast. Wear safety glasses or a face
shield, a dust mask, earplugs, a leather apron and
heavy leather boots.
• DO NOT lean into the workpiece in a manner that
may cause your hands to move into the spinning
wheel if the workpiece slips off.
• Concentrate on the task at hand. STOP grinding/
sanding if there are distractions.
NOTICE! The grinder is designed for use with
hard metals only. Soft metals and wood pro-
ducts should only be used on the sanding belt.
They will quickly load the grinding wheel surface
and ruin its abrasive qualities.
OPERATING GRINDER
To grind with the grinding wheel:
1. Fill the coolant tray 3/4 full with water.
2. Move the red switch to the ON position.
3. Allow the machine to run for at least 1 full minute
to ensure that the grinding wheel is safe for use.
4. Grasp the workpiece tightly and properly support
it on the tool rest.
5. Place the workpiece against the front surface of
the wheel with moderatepressure, moving it back
and forth in a steady, even motion.
6. Regularly dip the workpiece into the coolant tray
to cool it off.
7. When you are ready to stop the grinder, move the
red switch to the OFF position. At this point, DO
NOT continue grinding and DO NOT manually
stop the grinding wheel with your workpiece!
Note: Using too much pressure will slow the motor
and may damage the wheel. Using too little pres-
sure will make the workpiece bounce around and
you will not make good contact with the wheel.
CAUTION! The sanding belt will remove large amo-
unts of material quickly, including your skin. DO NOT
touch the sanding belt and always position your
hands so they will not slip into the belt or get caught

in the belt.
OPERATION
The2in.sanding belt on the machine works great
for non-ferrous metals and wood products. A wide
variety of belts are also available for many types
of materials and stages of finishing.
To sand a workpiece:
1. Before starting the machine, adjust the angle
of the tool rest so your workpiece is supported
and the area you wish to sand is parallel with
the sanding belt as illustrated（in Fig 7）.
2. With the machine plugged into power, stand
to the side of the grinding wheel and move
the red switch to the ON position.
Figure 7
3. Allow the machine to run for at least 1 full mi-
nute to make sure that the grinding wheel is
not going to fly apart and injure you, then move
to the front of the machine.
4. Grasp the workpiece tightly and properly
support it on the tool rest.
5. Press the workpiece evenly against the sa-
nding belt with light pressure (see Fig 8 and 9).
DO NOT press hard. Let the rotation of the
belt do the work.
6. Remove your workpiece regularly to check
the progress the sander has made.
Remember you can always remove more
material but you cannot add it.
7. When you are finished sanding, move the red
switch to the OFF position. DO NOT continue
sanding and DO NOT manually stop the san-
ding belt with your workpiece.

MAINTENANCE
1. Maintain the tool with care. A tool in good con-
dition is efficient, easier to control and will have
fewer problems.
2. Inspect the tool components periodically.Repair
or replace damaged or worn components.
3. Follow instructions for lubricating and changing
accessories.
4. When servicing, use only identical replacement
parts. Only use accessories intended for use with
this tool. Replace damaged parts immediately.
5. Maintain the tool’s label and name plate.These
carry important information.
6. Wheels should be dressed periodically to mai-
ntain grinding efficiency,especially if they become
clogged from grinding soft metals. Use a grinding
wheel dresser to restore the wheel’s original
shape.
7. Keep all parts in working order. Check to dete-
rmine that the guard or other parts will operate
properly and perform their intended function.
8. A guard or other part that is damaged should be
properly repaired or replaced. Do not perform
makeshift repairs. Use the parts list provided to
order replacement parts.
9. Disconnect tool when changing grinding wheels.
10. Replace a cracked wheel immediately and use
only flanges supplied with the grinder.
Only qualified service personnel should repair the
tool. An mproperly repaired tool may present a
hazard to the user and/or others.
WARNING
!
Your safety depends, on a large part, on the co-
ndition of the wheel during grinding.A wheel in poor
condition may break apart during rotation,injuring
the operator, a bystander and possibly causing
property damage.
To properly care for your wheel, follow these tips:
• Always transport, store and handle wheels with
care. Wheels may be damaged if they are dro-
pped or if heavy objects are stacked on them.
• Select the right grinding wheel for the job. DO
NOT grind material that is not designed for the
wheel.
• Select the right wheel for the machine. A mac-
hine that rotates at a higher RPM than the wheel
WHEEL CARE
rating may cause the wheel to fly apart.
• Mount the wheels properly (see Replacing
Wheels). Never use a wheel with the wrong
arbor size for the grinder.
• DO NOT abuse the wheel by jamming the work
into the grinding wheel with excessive force.
• Grinding on the side of the wheel may cause
wheel damage.
• Dress the grinding wheel when the surface loses
its abrasive quality or bite.
Dressing restores the grinding wheel’s abrasive
quality. Whenever the front surface of the wheel
loses its abrasive qualities (loading or polishing),
then the wheel should be dressed.
To dress the grinding wheel:
1. With the machine plugged into power, stand
to the side of the grinding wheel and move the
red switch to the ON position.
2. Allow the machine to run for 1 full minute to
make sure that the grinding wheel is not going
to fly apart and injure you, then move to the
front of the machine.
3.Hold the dressing tool firmly on the tool rest
with both hands and press it lightly against
the front surface of the grinding wheel as
shown( in Fig10).
4.Move the dressing tool in a side-to-side motion,
while keeping it even with the front surface of
the grinder.
5.Regularly pull the dressing tool away from the
wheel for visual inspection and repeat Steps 3
&4 until the surface of the wheel appears to be
restored to its normal color and texture.

MAINTENANCE
Before mounting a new grinding wheel, it must
be inspected. DO NOT assume that a wheel
is in sound condition because it is new. Dam-
age can occur during shipping, with age or
exposure to moisture.
Visually inspect the wheel. Look for any cr-
acks, chips, nicks or dents in the wheel’s
surface. DO NOT use the wheel if you see any
of these, Perform a Ring Test. This
test will
give you an indication of any internal damage
that may not be obvious during
a visual inspection.
To perform a Ring Test:
1. Make sure the wheel that you test is clean
and dry; otherwise, you may get false results.
2. Balance the wheel with your finger in the
hole if size permits, If this is not possible,
hang the wheel in the air with a piece of
cord or string looped through the hole in
the centert.
WHEEL INSPECTION
3. At the spots shown in Figure 11, gently
tap the wheel with a light non-metallic
device such asthe handle of a screwdriver
or a wooden mallet.
4. An undamaged wheel will emit a clear me-
tallic ring or "ping" sound in each of these
spots. A damaged wheel will respond with
a dull thud that has no clear tone.
5. DO NOT use it if you determine from the
ring test that the wheel is damaged.
Figure 11
REPLACING WHEELS
The wheel guard assembly must be re-
moved in order to mount or dismount a
grinding wheel.
To remove/mount a wheel:
1. Disconnect the grinder from the power
supply.
2. Remove the three Phillips head screws
and nuts that go through the outer guard.
Take off the outer guard and the rim
guard.
3. Use a wrench on the nut that holds the
wheel on the arbor. Hold the wheel to
prevent it fromturning with your other
hand.The grinding wheel arbor has a
left-handed thread. Loosen the nut by
turning it clockwise.
4. Remove the outer wheel flange and p-
aper disc. Pull the wheel free from the
arbor.There will also be a paper disc
and a wheel flange on the back side of
the wheel which should also be removed.
5. Mount the new wheel in the reverse o-
rder or as shown in Figure 12. Always
make certain there is are paper or fiber
discs between the wheel flanges and
the wheel itself.Tighten the nut snugly
but DO NOT over-tighten.Over-tightening
can crack the wheel.
6. Re-install the guards and shields.
7. Run a new wheel for at least one minute
while standing clear of the line of rota-
tion.If a wheel does have defects it will
generally fail as soon as it gets up to
full speed.
The hazards of using a damaged wheel
include flying chunks of sharp abrasive
material that could cause serious injury
or death. Inspect every grinding wheel
before it is mounted and DO NOT use a
damaged grinding wheel!
