Specific Safety
Warnings
a) Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by
hand.
b) Do not work materials containing asbestos. Asbestos is consideredcarcinogenic.
c) Take protective measures when dust can develop during working that is harmful to one’s health,
combustible or explosive.
Example: Some dusts are regarded as carcinogenic. Wear a dust mask and work with dust/chip extraction
when connectable.
d) Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or
explode.
e) Never leave the power tool before it has come to a complete stop. Cutting tools that are still running can
cause injuries.
f) Do not use the power tool with a damaged cord. Do not touch the damaged cord and pull the plug from the
outlet when the cord is damaged
while working. Damaged cords increase the risk of an electric shock
g) Connect power tools that are used in the open via a ground fault circuit interrupter.
h) Never stand on the power tool. Serious injuries could occur when the power tool tips over or when
accidentally coming into contact with the cutting disc.
i) Use the power tool only for dry cutting. Water penetrating into a power tool increases the risk of an electric
shock.
j) Keep hands away from the cutting area while the machine is running. Danger of injury when coming into
contact with the cutting disc.
k) Never remove cutting remainders, metal chips, etc. from the cutting area while the machine is running.
Always guide the tool arm back to the neutral position first and then switch the machine off.
l) Guide the cutting disc against the workpiece only when the machine is switched on. Otherwise, there is
danger of kickback, when the cutting disc becomes wedged in theworkpiece.
m) Operate the power tool only when the work area to the workpiece is clear of any adjusting tools, metal
chips, etc. Small pieces of metal or other objects that come in contact with the rotating cutting disc can strike the
operator with high speed.
n) Always firmly clamp the workpiece. Do not cut workpieces that are too small to clamp. Otherwise, the
clearance of your hand to the rotating cutting disc is too small.
o) Pay attention that persons are not put in danger by sparking. Remove any combustible materials in the
vicinity. Sparks develop when cutting metal.
p) Use the cut off grinder only for cutting materials mentioned under “Intended Use”. Otherwise, the cut off
grinder can be subject to overload.

3|English
q) Do not use damaged, out-of-center or vibrating cutting discs. Damaged cutting discs cause increased
friction, binding of the cutting disc and kickback.
r) Always use cutting discs with correct size and shape (diamond versus round) of arbor holes. Cutting
discs that do not match the mounting hardware of the cut off grinder will run eccentrically, causing loss of
control.
s) Do not touch the cutting disc after working before it has cooled. The cutting disc becomes very hot while
working.
Safety Warnings for Cut Off Saws with Retracting Blade Guard
Make sure that the blade guard operates properly and can move freely. Never clamp the blade guard in
place while retracted.
Specific safety rules
a) Maintain labels and nameplates on the Cut-Off Saw. These carry important information. If unreadable or
missing, contact our company for a replacement.
b) Keep hands and fingers away from cutting area and Grind Wheel. Keep one hand on the handle and
your second hand on the motor housing. If both hands are holding the saw, your hands and fingers cannot
be cut by the Grind Wheel.
c) Do not reach under the Base of the Cut-Off Saw. The Upper Guard can not protect you from the Grind
Wheel below the base.
d) Check Upper Guard for proper closing before each use. Do not operate the Saw if the Upper Guard
does not move freely and close instantly. Never clamp or tie the Upper Guard into the open position. If
the Saw is accidentally dropped, the Upper Guard may be bent. Raise the Upper Guard and make sure it
moves freely and does not touch the Grind Wheel or any other part, in all depths of cut.
e) The Upper Guard should be retracted manually only for special cuts such as "Pocket Cuts" and
"Compound Cuts". Raise the Swing Guard only enough to begin the cut. As soon as the Grind Wheel
enters the material, the Upper Guard must be released. For all other sawing, the Upper Guard should
allowed to operate automatically.
f) The Saw is not to be used for any cutting operation in the locked down position. The Saw should be in
the locked down position only for carrying and storage.
g) Always use Grind Wheels with a 355mm Diameter,25.4mm round arbor hole, and rated at a minimum of
3900/min. Grind Wheels that do not match the mounting hardware of the Saw or that are rated at less than
the saw’s maximum RPM may fly off the Saw or may run eccentrically , causing loss of control.
h) Never use damaged or incorrect Grind Wheel washers or bolts. The Grind Wheel’s washers and bolt were
specially designed for your Saw, for optimum performance and safety of operation.
i) Do not use the included Grind Wheel to cut aluminum, copper, brass, or other non-ferrous metals. The
included Grind Wheel is designed to cut only ferrous (iron containing) metals such as steel alloys and cast
iron. If using other Grind Wheels, only use them on materials that the manufacturer recommends.
j) To avoid accidental injury, always wear heavy duty work gloves and work bib when changing a Grind
Wheel.
k) Before using the Cut-Off Saw, make sure the Grind Wheel is properly mounted on the Saw Spindle.
Make sure the Grind Wheel is balanced, and is not cracked or bent.
l) The Grind Wheel will become hot while cutting. Allow the Grind Wheel to completely cool before touching.
m) Allow the Grind Wheel to spin up to full speed before feeding it into the workpiece, When turning off the
Saw, allow the Grind Wheel to spin down and stop on its own. Do not press against the Grind Wheel to stop it.
n) Do not force the Grind Wheel into the workpiece when cutting. Apply moderate pressure, allowing the
Grind Wheel to cut without being forced.
o) Always turn off the Cut-Off Saw and unplug the Cord from its electrical outlet before changing
accessories or performing any inspection, maintenance, or cleaningprocedures.
p) Use the right tool or attachment for the right job. Do not attempt to force a small tool or attachment to do
the work of a larger industrial tool or attachment. There are certain applications for which this product was

Inspection, maintenance and cleaning
1. WARNING ! Always make sure the Switch is in its “OFF” position, and unplug the Cord from its 230 volt
electrical outlet before performing any inspection, adjustments, maintenance, or cleaning.
2. Before each use, inspect the general condition of the Cut-Off Saw. Check for loose screws, misalignment or
binding of moving parts, cracked or broken parts, damaged electrical wiring, loose, cracked, or bent Grind
Wheel, and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, have
the problem corrected before further use. Do not use damaged equipment.
3. Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the Cut-Off Saw. Then, use a
premium quality, lightweight machine oil to lubricate all moving parts, except the Grind Wheel itself.
4. To replace the Motor Carbon Brushes: It may become necessary at sometime to replace the two Carbon
Brushes when the Motor performance decreases, or stops working completely. The Carbon Brushes are
located on each side of the Housing. To do so, use a standard screwdriver (not included) to remove the two
Brush holder Caps. Then, remove the two Carbon Brushes from the Brush holders. If the Carbon Brushes are
worn down more than 1/2 of the original size, replace both Carbon Brushes. If however, the Carbon Brushes
are just dirty they may be cleaned by rubbing them with a pencil eraser. When installing the Carbon Brushes,
make sure the carbon portion of the Carbon Brushes contact the Motor Armature, and that the springs face
away from the Motor. Also, make sure the springs operate freely. After cleaning or replacement, replace the
Carbon Brush Caps with a screwdriver and tighten firmly.
NOTE: New Carbon Brushes tend to arc or spark when first used until
They wear and conform to the Motor's Armature. ( See Figure J )
