Safety ules
As with all machines, there is a certain amount of hazard involved with the use of this circular saw-
bench. Use the machine with the respect and caution demanded where safety precautions are con-
cerned. When normal safety precautions are overlooked or ignored, personal injury to the operator can
result.
Read, understand and follow the safety and operating instructions found in this manual. Know the
limitations and hazards associated with this circular sawbench.
Electrical grounding. ake certain that the machine frame is electrically grounded and that a ground
lead is included in the incoming electrical service. In cases where a cord and plug are used, make cer-
tain that the grounding plug connects to a suitable ground. Follow the grounding procedure indicated in
the local electrical code.
Eye safety. Wear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Common eye
glasses are not safety glasses.)
Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll
up sleeves above the elbows. Remove all loose outer clothing and confine long hair. Protective type
footwear should be used. Do not wear gloves.
Guards. Keep the machine guards in place for every operation for which they can be used. If any
guards are removed for maintenance, DO NOT OPERATE the machine until the guards are re-installed.
Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other
liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign materi-
al and tools before starting to cut. ake certain the work area is well lighted and that a proper exhaust
system is used to minimize dust. We recommend the use of anti-skid floor strips on the floor area where
the operatornormally stands and that each machine’s work area is marked off. Provide adequate work
space around the machine.
Operator position. aintain a balanced stance and keep your body under control at all times. Do not
stand in line with the saw blade or work piece and do not allow anyone else to do so. Never climb on or
near the saw.
Do not overreach. Use a support table or have a helper or “tailman” take stock away from the back
side of the blade.
Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap,
and cleaning rags away from the saw.
Careless acts. Give the work you are doing your undivided attention. Looking around, carrying on a
conversation, and “horseplay” are careless acts that can result in serious injury.
Disconnect machine before performing any service or maintenance or when changing blades. A
machine under repair should be RED TAGGED to show it should not be used until the maintenance is
complete.
Alignment. Check the alignment of the splitter, fence and miter slot to the blade. A caution decal is
installed on each guard and splitter to remind the operator of the dangers of mis-alignment.
Maintain tools in top condition. Check the saw blade for cracks or missing teeth. Do not use a
cracked or dull blade or one with missing teeth or improper set. ake sure the blade is securely locked
on the arbor.
Hand safety. Keep hands clear of the blade area. Do not reach past the blade to clear parts or scrap
with the saw blade running. Never saw free hand. Avoid awkward operations and hand positions where
a sudden slip could cause your hand to contact the blade.
Safety devices. Always use the splitter, blade guard, push stick and other safety devices for all opera-
tions where they can be used. On operations such as dadoing or molding where the blade guard cannot
be used, use feather boards, fixtures and other safety devices and use extreme caution. Reinstall the
splitter and blade guard immediately after completing the operation that required their removal.
Saw blade rotation. Be sure the saw blade rotates clockwise when viewed from the motor side (left
side) of the machine.
Adjustments. ake all adjustments to the machine and operational setup with the power off. Never
remove the insert with the blade running.
Material condition. Do not attempt to saw boards with loose knots or with nails or other foreign materi-
al, on its surface. Do not attempt to saw twisted, warped, bowed or “in wind” stock unless one edge has
been jointed for guiding purposes prior to sawing.

Large stock. Do not attempt to saw long or wide boards unsupported where spring or weight could
cause the board to shift position.
Job completion. If the operator leaves the machine area for any reason, he should turn “off” the power
to the table saw motor and wait until the saw blade comes to a complete stop before his departure. In
addition, if the operation is complete, he should clean the table saw and the work area. NEVER clean off
the table saw with power “on” and NEVER use the hands to clear sawdust and debris; use a brush.
If you are not thoroughly familiar with the operation of this circular sawbench, obtain advice from your
supervisor, instructor or other qualified person.
Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs, alcohol,
or any medication.
Health hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
* Lead from lead-based paint.
* Crystalline silica from bricks and cement and other masonry products.
* Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment,
such as those dust masks that are specifically designed to filter out microscopic particles.
Use proper extension cord: ake sure your extension cord is in good condition. When using an exten-
sion cord, be sure to use one heavy enough to carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of power and overheating. If in doubt, use the next
heavier gauge the smaller the gauge number, the heavier the cord.
General Safety Procedures for Table Saw
This machine has been built exclusively for woodworking. Do not alter the design of the machine or use
it for purposes not intended by the manufacturer. The manufacturer is not liable for damage or injury,
which results from incorrect assembly, operation or electrical connections. This machine must be operat-
ed under strict safety regulations. This is the only way to reduce the risk of accidents.
Location
Certain types of woods. press boards, etc. produce hazardous dust emissions when being processed.
For this reason, processing procedures must be performed with an exhaust unit (air speed at the con-
nection points: 20m/s) Be sure to switch on the machine and the exhaust unit simultaneously. The main
cable plug must be connected as appropriate for the electrical installation and must have an earth lead
(or a directly earth conductor for 380 V). It is advisable to have a qualified electrical connection.
Appropriate lighting must be provided in the work area.
The Operator
Read the operating manual carefully to prevent machine accidents. Never work while under the influ-
ence of drugs, alcohol or medications. Wear tight-fitting work clothes, safety goggles and safety shoes
and tie back long hair. Remove rings, wrist watches and bracelets before working.
Ear protection is recommended. Never climb onto the machine table: the machine may fall and cause
injuries.
Keep children and visitors out of the work area.
Before working
Check that the sawing tool type is suited for the intended work. Immediately replace damaged or dull
sawing tools. Only work with the appropriate standard accessories. Always work with well-sharpened
sawing tools increase the risk of wood kick back. Note the correct rotational direction. As a general rule,
check that sawing tool wrenches and other items have been removed. Check that the sawing tool can
rotate freely and does not contact the limit stop, the safety equipment, the work piece or other objects.
Keep out of the kick-back zone.

While working
Wood must be hand fed uniformly and without jerking into the sawing tool, slightly more slowly when
processing hard wood or work pieces, which produce large amounts of dust. Never move the work piece
during a processing operation. Avoid uncomfortable working stances to reduce the risk of contacting the
rotating sawing tool. Do not bend over the rotating sawing tool. Remove debris from the machine table
only when the machine is off. Never use the machine table as a worktable while the sawing tool is rotat-
ing.
After working
Never leave the machine operating without supervision. Remain at the machine until the sawing tool has
come to a complete stop. Remove debris and clean the machine and surrounding area so that the
machine is ready to use the next time.
Machine maintenance
Unplug the mains cable before any mechanical or electrical work is per-formed or when the sawing tool
is changed. Regularly lubricate mechanical parts: threaded rods, gears, driving chains, hinges, sliding
parts,etc.
Grounding Instructions
Caution: This tool must be grounded while in use to protect the operator from electric shock.
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 tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accordance 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 a 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 replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension
cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.
Repair or replace a damaged or worn cord immediately.
