GENERAL SAFETY RULES
Safety is a combination of common sense, staying alert and knowing how your item works. SAVE THESE SAFE-
TY INSTRUCTIONS.
WARNING: To avoid mistakes and serious injury, do not plug in your tool until the following steps
have been read and understood.
1. READ and become familiar with this entire instruction manual. LEARN the tool’s applications, limitations, and
possible hazards.
2. AVOID DANGEROUS CONDITIONS. Do not use power tools in wet or damp areas or expose them to rain.
Keep work areas well lit.
3. DO NOT use power tools in the presence of flammable liquids or gases.
4. ALWAYS keep your work area clean, uncluttered, and well lit. DO NOT work on floor surfaces that are slippery
with sawdust or wax.
5. KEEP BYSTANDERS AT A SAFE DISTANCE from the work area, especially when the tool is operating.
NEVER allow children or pets near the tool.
6. DO NOT FORCE THE TOOL to do a job for which it was not designed.
7. DRESS FOR SAFETY. Do not wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) when op-
erating the tool. Inappropriate clothing and items can get caught in moving parts and draw you in. ALWAYS wear
non-slip footwear and tie back long hair.
8. WEAR A FACE MASK OR DUST MASK to fight the dust produced by sawing operations.
WARNING: Dust generated from certain materials can be hazardous to your health. Always oper-
ate the tool in a well-ventilated area and provide for proper dust removal. Use dust collection systems
whenever possible.
9. ALWAYS remove the power cord plug from the electrical outlet when making adjustments, changing parts,
cleaning, or working on the tool.
10. KEEP GUARDS IN PLACE AND IN WORKING ORDER.
11. AVOID ACCIDENTAL START-UPS. Make sure the power switch is in the OFF position before plugging in
the power cord.
12. REMOVE ADJUSTMENT TOOLS. Always make sure all adjustment tools are removed from the saw before
turning it on.
13. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to OFF. Do not leave the
tool until it has come to a complete stop.
14. NEVER STAND ON A TOOL. Serious injury could result if the tool tips or is accidentally hit. DO NOT store
anything above or near the tool.

4
15. DO NOT OVERREACH. Keep proper footing and balance at all times. Wear oil-resistant rubber-soled foot-
wear. Keep the floor clear of oil, scrap, and other debris.
16. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow instruc-
tions for lubricating and changing accessories.
17. CHECK FOR DAMAGED PARTS. Check for alignment of moving parts, jamming, breakage, improper
mounting, or any other conditions that may affect the tool’s operation. Any part that is damaged should be properly
repaired or replaced before use.
18. MAKE THE WORKSHOP CHILDPROOF. Use padlocks and master switches and ALWAYS remove safety
keys.
19. DO NOT operate the tool if you are under the influence of drugs, alcohol, or medication that may affect your
ability to properly use the tool.
20. USE SAFETY GOGGLES AT ALL TIMES that comply with ANSI Z87.1. Normal safety glasses only have
impact resistant lenses and are not designed for safety. Wear a face or dust mask when working in a dusty environ-
ment. Use ear protection such as plugs or muffs during extended periods of operation.
GENERAL SAFETY RULES
1. ALWAYS USE THE BLADE GUARD, riving knife and anti-kickback fingers on all “through-sawing” opera-
tions. Through-sawing operations are those when the blade cuts completely through the workpiece as in ripping or
crosscutting.
2. AVOID KICKBACKS by keeping the blade sharp and the rip fence parallel to the saw blade. Make sure the riv-
ing knife, anti-kickback fingers, and the blade guard are in place, aligned properly and functional. Do not release a
work piece before passing it completely through the saw blade. Do not rip a work piece that is twisted/warped or a
work piece that has a straight edge to guide it along the rip fence. Do not attempt to pull the workpiece backwards
out of a cut while the blade is still turning.
3. ALWAYS HOLD THE WORK firmly against the miter gauge or fence.
4. NEVER PERFORM FREE-HAND OPERATIONS, meaning never only use your hands to support or guide
the workpiece. Always use either the fence or the miter gauge to position and guide the workpiece.
5. BE MINDFUL OF BODY POSITION. Never have any part of your body in line with the path of the saw blade.
6. NEVER REACH BEHIND or over the saw blade with either hand for any reason.
7. MOVE THE RIP FENCE out of the way when crosscutting.
8. SUPPORT LARGE PANELS to minimize the risk of blade pinching and kickback.
SPECIFIC RULES FOR TABLE SAWS

5
SPECIFIC RULES FOR TABLE SAWS
9. REMOVE ALL ACCESSORIES FROM THE TABLE. Before transporting the saw, remove all accessories
(miter gauge, rip fence....). Failure to do so can result in an accident causing possible serious personal injury.
10. NEVER USE RIP FENCE AS A CUT-OFF GAUGE when crosscutting. Move the rip fence out of the way.
11. NEVER ATTEMPT TO FREE A STALLED BLADE without first turning the saw OFF. If a work piece stalls
the blade, turn the saw off and unplug it for both safety and also damage prevention to the motor.
12. PROVIDE ADEQUATE SUPPORT to the rear and sides of the table saw for wide or long workpieces.
13. AVOID AWKWARD OPERATIONS and hand positions where a sudden slip could cause your hand to
move into the spinning blade.
14. MOUNT YOUR TABLE SAW on the supplied stand or to a work bench before performing any cutting opera-
tions.
15. NEVER CUT METALS or materials that may make hazardous dust.
16. ALWAYS USE A PUSH STICK, especially when ripping narrow work piece. One is supplied with this saw.

DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools that eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protect-
ing insulation. Double insulated tools do not need to be grounded.
WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the
tool’s internal insulation. Observe all normal safety precautions to avoid electrical shock.
NOTE: Servicing a product with double insulation requires extreme care and knowledge of the system. This should
be performed only by a qualified service technician. For service, we suggest you return the product to your nearest
authorized service center for repair. Always use original replacement parts intended for your particular model of
tool when servicing.
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.
GUIDELINES FOR USING EXTENSION CORDS
Make sure your extension cord is in good condition. When using an extension 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. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should
be protected with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure
the switch is in the OFF position and the electric current is rated the same as the current stamped on the
motor nameplate. Running at a lower voltage will damage the motor.
WARNING: This tool must be grounded while in use to protect the operator from electric shock.

Push the stand release latch (A, Fig 4) and at the same time, grasp
the stand handles (B, Fig 4) and pull them down towards you. Push
down until the release latch clicks and locks the stand. The stand and
saw assembly can now be used for making cuts.
ADJUSTING RIVING KNIFE
Remove the table insert (A, Fig 7) from the table top by pulling it
upwards. Turn the blade height lock knob (A, Fig 5) counterclock-
wise to unlock. Turn the elevation handwheel (B, Fig 5) counter-
clockwise and raise the blade to its highest position above the table.
The riving knife (B, Fig 7) consists of a metal piece, slightly thinner
than the blade, that helps to keep the blade kerf open to prevent
kickback. This saw is shipped with the riving knife in the non-
through cutting or “down” position, as shown in illustration below.
The riving knife must be positioned in the through cutting or “up”
position for all other operations.
1. Unlock the riving knife lock lever (C, Fig 7) by pivoting it up-
wards (vertical position).
2. Push the riving knife (B, Fig 7) towards the lock lever to disen-
gage it from its positioning pins/slots.
3. Pull the riving knife upwards until its bottom mounting holes
engage the positioning pins and the riving knife is above the saw
blade.
4. Lock the lock lever (C, Fig 7) by pivoting it downwards (horizon-
tal position). Once secured, make sure the riving knife is perfectly
aligned with the centre of the blade, if not, it is most likely due to
misalignment of the positioning pins, readjust until alignment is
obtained.
5. Reinstall the table insert.

ASSEMBLY AND ADJUSTMENTS
ALIGNING RIVING KNIFE
IMPORTANT: If riving knife is correctly mounted yet it is not
perfectly centered with the blade, proceed with the following
adjustment.
1. Using a straight edge (Fig 8), check if the riving knife is aligned
with the blade.
2. If an adjustment is necessary, loosen 2 cap screws (A, Fig 9)
that hold the mounting bracket (B, Fig 9). Adjust the position of
the riving knife to the right or left until it is perfectly aligned with
the blade. Retighten cap screws.
MOUNTING BLADE GUARD (Fig. 10)
1. Make sure the blade is raised to its highest position and the
riving knife is secured in the “up” position.
2. Make sure the table insert (A) is installed in the table top
opening.
3. Lower the back end shaft (B) into the middle slot (C) of the
riving knife. Pull the blade guard lock lever (D) toward the front
of the saw then pivot the blade guard towards the front of the
saw. Once the blade guard is parallel to the table, lock the blade
guard to the riving knife by pushing the lock lever down to the
lock position. Lift the blade guard up to check if it is locked
securely.

ASSEMBLY AND ADJUSTMENTS
MOUNTING RIP FENCE ON TABLE AND
ADJUSTMENTS
1. Position the front of the rip fence (A, Fig 12) on the front rail
(B, Fig 12). Lower the back end of the rip fence on the rear rail.
Check to make sure the rip fence slides freely on the rails.
2. Lower rip fence locking lever (C, Fig 12) to automatically align
and secure the rip fence in place.
3. This rip fence comes with an adjustment wheel (B, Fig 13)
which allows the user to make small adjustments of the rip fence
using only one hand. The rip fence lock lever (C, Fig 12) must be
raised to the unlocked position to use this feature.
REDUCING THE RISK OF KICKBACK (FIG 13)
The rip fence must be perfectly parallel to the blade. Unlock the
rip fence by raising locking lever (A). Loosen both hex bolts (C) on
top of the rip fence. Align the rip fence with the blade and retighten
both hex bolts (C). Adjust the rip fence pointer (E) to the same
marking by loosening pointer screw (F) and repositioning pointer.
MOUNTING AND ADJUSTING MITER GAUGE (FIG 14)
When crosscutting with the blade set at either 900 or 450 to the
table, the miter gauge can be used in either T-slot on the table.
When crosscutting and the blade is tilted, use the T-slot on right
side of table where the blade is tilted away from.
1. To adjust the miter gauge, loosen lock handle (A) and set the
miter gauge body with scale (B) so the indicator (C) aligns to the
desired cutting angle, then retighten the lock handle.
2. For best results, it is recommended to check the miter gauge for
squareness against the saw blade. Place a square against the blade,
loosen the lock handle (A) and place the miter gauge against the
square. Once the miter gauge body is perfectly square with the
blade, retighten lock handle (A). If the pointer (C) requires align-
ment, loosen the two screws under the miter gauge bar (D), reposi-
tion the pointer and finally retighten the screws.

ASSEMBLY AND ADJUSTMENTS
ADJUSTING THE EXTENDABLE EXTENSION TABLE
The extension table allows the user to increase the length of the
table for greater ripping capacity (maximum 25 in.). To use the
extension table:
1. Unlock or remove the rip fence from the table.
2. Unlock the extension table (A, Fig 15) by raising the extension
lock lever (A, Fig 16), slide the extension to the desired width. Use
the scale on the front rail when a specific width is desired.
3. Once the extension is in the desired position, lower the lock
lever (A) to secure the extension in place. The rip fence can now
be installed as shown in Fig 15.
ADJUSTING THE BLADE HEIGHT (FIG 17)
The blade height should be set 1/4 in. above the top of the
anticipated workpiece.
1. Turn the blade height lock knob (A) counterclockwise to un-
lock. Turn the handwheel (B) counterclockwise to raise the blade
or clockwise to lower the blade.
2. Once the blade is set in the desired height, turn blade height
lock knob (A) clockwise to lock blade position.
ADJUSTING THE BLADE ANGLE
Note: A 90° cut has a 0° bevel angle and a 45° cut has a 45° bevel
angle.
1. Unlock the bevel locking lever (A, Fig 18) by pulling the lever all
the way to the right.
2. Push in and then turn the exterior handwheel (B, Fig 20) to adjust
the blade bevel angle, turning it counterclockwise increases the bevel
angle of the blade.
3. Angle detents at 15°, 22.5° and 30° are provided for quick adjust-
ment, once one of these angles are reached you will hear and feel a
click, which means you have reached the detent angle.
4. Once the desired bevel angle is achieved, lock the bevel locking
lever (A, Fig 18) by pulling the lever all the way to the left.

ASSEMBLY AND ADJUSTMENTS
ADJUSTING THE BEVEL ANGLE INDICATOR
If the blade is at a 90° angle and the bevel indicator (A, Fig 20) does not
indicate 0° on the scale, an adjustment can be made:
1. Place a combination square (A, Fig.19) on the table and up against
the flat portion of the blade (B, Fig.19).
2. Unlock the bevel locking lever (A, Fig 18) by pulling the lever all the
way to the right. Push in and then turn the exterior handwheel (B, Fig
18) until the blade is set at a perfect 90°. Lock the bevel locking lever.
3. Loosen the screw (A) Fig.20 which secures the bevel indicator (B).
Readjust the position of the bevel indicator so it aligns with the 0° on the
bevel scale. Retighten screw (A).
ADJUSTING THE BLADE PARALLEL WITH THE TABLE T-
SLOT (FIG 22)
The blade must be aligned parallel with the table T-slot. Using a combi-
nation square (A), measure the distance from the back edge of the blade
(C) to the table T-slot (B). Pivot blade forward 180° and remeasure the
distance using the exact same point on the blade. The difference be-
tween both measurements must be equal to or less than 1/64”.
If an adjustment is necessary, loosen the four cap screws (D) that fix the
blade and motor assembly to the table top. Make the needed adjustment
to the blade position until both measurements are equal or less than
1/64” and retighten the four cap screws (D).
MARKABLE INSERT ON TABLE
A plastic markable insert (A, Fig 21) located in front of the saw blade is
provided for marking the location of the saw blade kerf (cut width) on
the workpiece.
1. Place the miter gauge in the left T-slot and make sure the blade angle
is exactly 90°.
2. Place and firmly hold a workpiece against the miter gauge body and
make the cross cut.
3. Turn the saw off. Once the blade has come to a complete stop, pull
the miter gauge back until the freshly cut workpiece is over the markable
insert (A, Fig. 21).
4. Using a sharp pencil, mark a line on the insert at the edge of the
freshly cut workpiece. Repeat steps 1-4 but place the miter gauge in the
right T-slot instead to make the second mark on the insert.
Note: Both these lines indicate the blade kerf made by the blade. If you
change the blade the marks will need to be erased and the above steps
will need to be repeated.

blade to prevent the saw arbor and blade from rotating. Then place
the closed end of the second adjustment wrench (B, Fig 23) on the
arbor nut (A, Fig 24) and turn the arbor nut counterclockwise. Re-
move the arbor nut and outside blade flange (B, Fig 24).
4. Place new blade on arbor (D, Fig 24) making sure the blade teeth
point downwards towards the front of the table saw.
5. Replace outside blade flange (B, Fig 24) and arbor nut (A, Fig 24)
on arbor shaft and tighten with arbor wrenches.
6. Reinstall the table insert. Then reinstall the blade guard and anti-
kickback fingers assembly.
OPERATION
SAFETY PRECAUTIONS BEFORE OPERATION
The operation of power tools involves a certain amount of hazard for the operator. Before attempting regular
work, we recommend you get the feel of operations using scrap lumber to double check your settings. It is good
practice to make trial cuts using scrap material when setting up your saw for operation.
PUSH STICK
A push stick is supplied with this table saw and should be used whenever possible.
OPERATION
Normal sawing procedure includes ripping and crosscutting, plus a few other standard operations. As with all pow-
er tools there is a certain amount of hazard involved with the operation and use of the tool. Using the tool with
respect and caution will considerably lessen the potential of personal injury. However, if normal safety precautions
are overlooked or completely ignored, personal injury to the operator can occur.
Fig. 23
Fig. 24

15
OPERATION
CROSS CUTTING
Cross cutting requires the use of the miter gauge to position and guide the work piece. Place the work piece
against the miter gauge and advance both the miter gauge and work piece toward the saw blade keeping your
hands and fingers clear of the path of the blade. The miter gauge may be used in either table T-slot, however,
most operators prefer the left groove for average work. When bevel cutting (blade tilted), use the right side table
T-slot so that it doesn’t interfere with the tilted saw blade. The blade guard must be used. The guard has anti-kick-
back fingers and a riving knife to prevent the saw kerf from closing.
Start the cut slowly and hold the work piece firmly against the miter gauge and the table. One of the rules in run-
ning a saw is that you never hang onto or touch the piece being cut off. Hold the supported piece instead. Cross-
cutting continues until the work is cut in two, then the miter gauge and work are pulled back to the starting point.
Before pulling the work back it is good practice to give the work a little sideways shift to move the work slightly
away from the saw blade.
Never pick up any short length of free work from the table while the saw is running. A smart operator never
touches a cut-off piece unless it is at least 1 foot long. Never use the rip fence as a cut-off gauge when crosscutting.
RIPPING
Ripping is the operation of making a lengthwise cut through a board. The rip fence is used to position and guide
the work. One edge of the work piece rides against the rip fence while the flat side of the board rests on the table.
Since the work piece is pushed along the fence, it must have a straight edge and make solid contact with the table.
The blade guard must be used at all times. The guard has anti-kickback fingers and a riving knife to prevent the
saw kerf from closing.
Start the motor and advance the work piece forward, holding it down and against the fence. Never, stand in the
line of the saw cut when ripping. Hold the work with both hands and push it along the fence and into the saw
blade. The work can then be fed through the saw blade with one or two hands or the use of the push stick.
When this is done the work piece will either stay on the table, tilt up slightly and be caught by the rear end of the
guard or slide off the table to the floor.
Alternately, the feed can continue to the end of the table, after which the work piece is lifted and brought back
along the outside edge of the fence. The waste stock remains on the table and is not touched with the hands until
the saw is stopped unless it is a large piece allowing safe removal.
MAKING A NON-THROUGH CUT
Non-through cuts can be made with the grain (ripping) or across the grain (cross cut). Non-through cuts are
needed for cutting grooves, rabbets and dadoes. This is the only type of cut where the blade gets covered by the
workpiece. These types of cuts are made without the blade guard and anti-kickback finger assemblies in place.
Make sure the blade guard and anti-kickback finger assemblies are reinstalled after this type of cut is done. For
non-through cuts, position the riving knife in the “down” position, set the blade to the correct height and tighten
the blade height lock knob.

MAINTENANCE
WARNING: Always ensure that the tool is switched off and the plug is removed from the outlet before
making any adjustments or maintenance procedures.
•Any damage to this tool should be repaired and carefully inspected by qualified repair personnel be-
fore use.
•Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will maintain the safety of the power tool.
•Great Lakes Technologies, LLC will not be responsible for any damage or injury caused by unauthor-
ized repair or mishandling of the tool.
POWER CORD MAINTENACE
If the supply cord needs replacing, the manufacturer, the manufacturer’s agent, or an authorized service centre
must carry out the task in order to avoid a safety hazard.
CLEANING
1. Keep the tool’s air vents unclogged and clean at all times.
2. Remove dust and dirt regularly. Cleaning is best done with a soft brush or a rag.
3. Re-lubricate all moving parts at regular intervals.
CAUTION: Do not use cleaning agents to clean the plastic parts of the saw. A mild detergent on a damp cloth is
recommended. Regularly check that all screws are tight. They may vibrate loose over time.
USING A DADO BLADE SET (OPTIONAL) AND DADO
INSERT
Dadoing is cutting a rabbet or a wide groove into the work. Most
dado head sets are made up of two outside blades and four or five
inside cutters, as shown in Fig. 25. Various combination of blades
and cutters are used to cut grooves from 1/8 in. to 13/16 in. for use
in shelving, making joints, tenoning, grooving, ect. The cutters are
heavily swaged and must be arranged so that this heavy portion falls
in the gullet of the outside blades, as shown in Fig. 26. The saw and
cutter overlap is shown in Fig.26, (A) being the outside blade, (B)
being the inside cutter, and (C) being a paper washer which can be
used as needed to control the exact width of groove. A 1/4 in. groove
is cut by using the two outside blades. The teeth of the blades should
be positioned so that the raker on one saw is beside the cutting teeth
on the other saw. The dado head set is assembled to the saw arbor
in the same manner as the saw blade. The blade guard and anti-
kickback finger assemblies can not be used when dadoing operations
and must be removed from the saw. The riving knife must be set in
the “down” position and the included dado table insert must be used
in place of the standard table insert. Never use the dado head in a
bevel position unless you make your own dado insert! Always rein-
stall blade guard and anti-kickback finger assemblies after operation
is complete!
