CONNECTING YOUR MACHINE TO THE POWER SUPPLY: (230V ONLY)
To eliminate the possibility of an electric shock your machine has been fitted with a BS approved,non rewireable moulded plug and cable which incorporates a fuse, the value of which is indicated on the pin face of the plug.Should the fuse need replacing an
approved BS1362 fuse must be used of the same rating, marked thus .
The fuse cover is detachable, never use the plug with the cover omitted. If a replacement fuse cover is required,ensure it is of the same colour as that visible on the pin face of the plug (i.e. red).Fuse covers are available from your Draper Tools stockist. If the fitted plug is not suitable, it should be cut off and destroyed. *The end of the cable should now be suitably prepared and the correct type of plug fitted. See below.
*WARNING:
A plug with bare flexible wires exposed is hazardous if engaged in a live power socket outlet.
WARNING:THIS APPLIANCE MUST BE EARTHED.
The mains lead is coloured Green and Yellow - Earth, Blue - Neutral & Brown - Live. As these colours may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured green and yellow must be connected to the terminal in your plug marked with the letter ‘E’ or by the earth symbol or coloured green or green and yellow. The wire which is coloured blue must be connected to the terminal which is marked with the letter ‘N’ or coloured black or blue. The wire which is coloured brown must be connected to the terminal which is marked with the letter ‘L’ or coloured red or brown.
EXTENSION LEAD CHART:
Extension lead sizes shown assure a voltage drop of not more than 5% at rated load of tool.

ADDITIONAL TABLE SAW SAFETY RULES
WARNING
For your own safety, do not operate your saw until it is completely assembled and installed according to the
instructions....and until you have read and understood
the following: All safety rules
Assembly procedures Adjustment procedures Maintenance Basic operations Operating controls
1. STABILITY.
The saw must be bolted down.There may be a tendency for the saw to tip over or move during certain cutting operations, such as, cutting extremely large heavy panels or long heavy boards.
2. MINIMIZE POTENTIAL ACCIDENTS.
Most accidents are caused by FAILURE TO FOLLOW SET UP AND OPERATION INSTRUCTIONS. Avoid awkward hand positions, where a sudden slip could cause a hand to move into a saw blade or other cutting tool. Never reach behind,or around,the cutting tool with either hand to hold down the workpiece,or for any other reason. DO NOT PLACE FINGERS OR HANDS IN THE PATH OF THE SAW BLADE.
3. Never reach under your machine when operating or make any adjustments when it is running.
4. Turn the saw 'OFF' and disconnect the power supply when changing the cutting tool,removing or replacing the blade guard, or making any adjustments.
5. Always maintain control of the workpiece. DO NOT 'LET GO' of the workpiece until the machine has stopped.
6. When removing short workpieces,or cleaning up around the table, be sure the saw is switched 'OFF'.
7. Never turn the saw 'ON' before clearing the table of all tools, wood scraps, etc., except the workpiece and related feed or support devices for the operation.
8.
When moving the saw, disconnect power supply
.
9. Never hold onto or touch the 'free end' of the workpiece or a 'free piece' that is cut off, while power is 'ON' and/or the saw blade is rotating.
10. If you stall or jam the saw blade in the workpiece, turn power 'OFF', remove the workpiece from the saw blade and check to see if the saw blade is parallel to the table slots or grooves and if the riving knife is in alignment with the saw blade.If ripping at the time, check to see if the rip fence is parallel with the saw blade.Adjust as indicated in this manual. WARNING:Do not allow familiarity (gained from frequent use of your saw) to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury.
11. MAKE SURE YOUR FINGERS DO NOT CONTACT THE TERMINALS OF THE POWER PLUG when installing or removing from the mains power supply.
12. KICKBACKS - THEIR CAUSE.
Kickbacks can cause serious injury.A kickback occurs when a part of the workpiece binds between the saw blade and the rip fence or another object rises from the table and is thrown towards the operator. Kickbacks can be avoided by attention to the following conditions.:
13. KICKBACK - HOW TO AVOID THEM AND PROTECT YOURSELF FROM POSSIBLE INJURY. a) Be certain that the saw blade is parallel to
the rip fence.
b) Do not rip by applying the feed force to the
section of the workpiece that will become the cut-off (free) piece.Feed force when ripping should always be applied between
the saw blade and the fence....use a push-
stick for short work or less than 6" wide.
c) Keep saw blade guard, riving knife and
anti-kickback pawls in place and operating properly.The riving knife must be in alignment with the saw blade and the pawls must stop a kickback once it has started. Check their action before using for ripping timber.
d) Plastic and composition (like hardboard)
materials may be cut on your saw. However, since these are usually quite hard and slippery, the anti-kickback pawls may not stop a kickback.Therefore, be especially careful to follow proper setting up and cutting procedures before ripping.
14. Do not leave a long board (or other workpiece) unsupported so the spring of the board causes it to shift on the table.Provide proper support for the workpiece, based on its size and the type of operation to be performed. Hold the work firmly against the fence and down against the table surface.
15. Never use a length stop on the free end of the workpiece when cross cutting.Never hold onto or touch the free end of the workpiece when cross cutting, or a free piece that is cut off when ripping while power is 'ON' and/or the saw blade is rotating. In short, the cut-off piece in any 'through-sawing' (cutting completely through the workpiece) operation must never be confined - it must be allowed to move laterally.
16. IF YOUR SAW MAKES AN UNFAMILIAR NOISE OR IF IT VIBRATES EXCESSIVELY,CEASE OPERATING IMMEDIATELY UNTIL THE SOURCE HAS BEEN LOCATED AND THE PROBLEM CORRECTED.
17. EXTENSION LEADS
The use of any extension lead will cause some loss of power. To keep this to a minimum and to prevent over heating and motor burn-out, use the table to determine the minimum size of extension cable required.Use only extension leads which have a 3-pin plug and 3-pin sockets which accept the tools plug.

ASSEMBLY
NOTE:
To correctly assemble and adjust this table saw, please read the following instructions carefully.
When this saw is first removed from it's packaging, the blade guard and riving knife assembly must be fitted.
When making any adjustment on the saw, ensure the power supply is turned off and the plug has been removed from the socket.
FITTING THE BLADE GUARD (FIG.2):
Turn the saw over so the underside is easily accessible. Remove the four nuts and bolts securing the protection vent plate to access the underside of the work table. Pass the riving knife part ✪✌ of the guard assembly through the slot ✫✌ in the work table and secure it in place with the two bolts ✬✌.
ADJUSTING THE RIVING KNIFE (FIG.3):
Set the blade to the full height adjustment and ensure that it is in the 0º position (see page 9) before adjusting the knife.
NOTE:
The riving knife must be adjusted 3mm (Max. 5mm) from the blade cutting tips.This adjustment is made on the two securing bolts and the elongated holes in the bracket from underneath. When set securely, tighten the bolts. This setting must be checked regularly.
This table saw must be securely fastened to the proper stand (Draper Stock No.65840) or to another appropriate supporting surface.
If choosing the Draper stand, refer to the instructions enclosed with the stand for all mounting procedures
If mounting to a work bench, allow sufficient space around the machine for long/wide material to be cut without interference. Also that cuts can be made without awkward positions, leading to possible user injury. For example,having to lean over the saw blade to retrieve the off cuts.

ASSEMBLY
ONLY WITH THE POWER SWITCHED OFF AND THE MACHINE UNPLUGGED SHOULD ANY ADJUSTMENTS, MAINTENANCE OR REPAIRS BE CARRIED OUT.
RIP FENCE (FIGS. 4 & 5):
CAUTION: THE RIP FENCE MUST BE ALIGNED
PARALLEL TO THE BLADE TO MINIMIZE THE DANGER OF KICK BACK.
Place the rip fence on the side of the table, most comfortable for your hand orientation. For example, if you are left handed, the fence would be secured to the right of the blade.
With the blade guard lifted out of the way, set the blade to the full height (see page 9) lift the kickback pawl up to allow the fence to be pushed flush to the blade. Lock the rear knob ✭✌and front locking handle ✮✌so the fence is securely held tight against the table. If the fence is not fully secure, remove the fence and at the rear on handle ✮✌, under the fence is an adjustment screw which when moved will allow more grip with the front handle.On the front fence assembly, ensure the marker guide is set to zero. If adjustment is required, loosen screw ✯✌, slide the plate so zero is correct and then retighten screw ✯✌. Now the fence can be slid to the desired width of cut and locked in place.To check the accuracy of the guide, use a metal rule from the fence and measure the gap between the front of the blade and also at the back.The measurement is from the cutting side of the tooth ✰✌.This measurement should be checked regularly and if necessary adjusted.When making critical cuts, always make a test cut from a piece of scrap timber.
MITRE GAUGE (FIG.6):
The mitre gauge is a guide. The gauge slides along the two grooves ✱✌ in the table. It should be checked against the blade using an engineers square (Draper Stock No.34065) to ensure greater accuracy. Loosen locking knob ✲✌ and using the square, set the gauge at 90º to the blade. Now lock knob ✲✌. Push in rod ✳✌and adjust quick stop ✴✌so the set screw touches rod ✳✌, and lock in place. Carry out the same procedure for the two 45º stops using a protractor (Draper Stock No.52430) against the blade.
NOTE:
The quick stop is designed to allow quick setting of the 90º and 45º angles on the gauge.To set other angles, pull rod ✳✌out and set manually. Ensure the locking knob ✲✌is secured before any cutting takes place.

OPERATION & USE
NOTE: ENSURE THE POWER IS SWITCHED OFF AND
THE MACHINE UNPLUGGED.
BLADE ADJUSTMENT (FIGS. 7, 8 & 9):
HEIGHT:
To move the blade up or down, turn handle ✵✌ clockwise or anticlockwise depending on requirements.The locking knob ✶✌ does not require loosening for this procedure (Fig.7).
CAUTION:
The saw blade must be set slightly higher than the thickness of the work piece being cut.
TILT ACCURACY:
The saw blade can be adjusted to cut between 0º and 45º. Loosen knob ✶✌ and slide the blade assembly until the 0º stop. Tighten knob ✶✌.
Using an engineers square on the table and against the blade, check the blade is in the 0º position. If a gap can be seen in between the square and the blade, adjustment is required, set the blade to the 45º stop and measure the 45º angle in the same manner using a protractor.
The 0º adjustment is made on bolt ✷✌ and the 45º adjustment is made on bolt ✸✌ (Fig.8).
Turn the bolts clockwise or anticlockwise to move the end stop, altering the blade angle slightly. When both angles are set accurately, adjust the angle indication pointer ✹✌ by loosening screw ✺✌. Make a test cut after any adjustment.
TILT:
Loosen lock ✻✌ and move the handle assembly ✼✌ along the arc to the desired angle as
indicated by the pointer ✹✌. Retighten locking knob ✻✌ (Fig.9).
CAUTION:
Ensure the locking knob ✻✌ is fully secured before any cutting operations take place.
NO-VOLT ON/OFF SWITCH (FIG.10):
This saw is fitted with a no-volt on/off switch. In the event of a power failure, the machine will have to be manually restarted once the power supply has been reinstated.

OPERATION & USE
CIRCUIT BREAKER (FIG.11):
The no-volt switch is fitted with a circuit breaker. Should the saw blade become snagged during a cut, the circuit breaker will trip out and cut power to the motor. This will help avoid the motor from burning out, once the blockage has been removed and the blade is free again, push button ❀✌ to reset the circuit breaker.Then the saw can be restarted on the no-volt switch.
DUST EXTRACTION (FIG.12):
Dust extraction is required when using this machine to reduce the amount of airborne dust particles. Connect the port to a suitable vacuum cleaner (Draper Stock No.64674).
NOTE:
When making any cuts, wear safety goggles, ear defenders and a dust mask.
RIVING KNIFE WITH ANTI-KICK BACK PAWLS (FIG.13):
The riving knife is used to keep the cut open in the wood behind the saw blade and avoid the saw blade becoming trapped.
The riving knife is fitted with anti-kick back pawls ❁✌ and must always remain fitted during cutting operations to avoid the off cuts kicking back towards the operator.
Using a straight edge,ensure the riving knife is in a straight line with the saw blade.
REPLACING THE SAW BLADE (FIG.14): CAUTION:
Ensure the power is switched off and the plug has been removed from the power supply socket before attempting any adjustment or replacement operations.
Lower the blade to its lowest position (see page 9). Remove the saw from the stand or workbench.Turn the saw over so the underside is easily accessible.Remove the four nuts and bolts securing the protection vent plate to access the underside of the work table. Remove the four bolts and blade cover ❂✌to gain access to the blade securing flange. Using the wrenches supplied, hold the flange ❃✌in place and remove the securing bolt. Replace the blade, ensuring the direction of rotation marked on the blade and direction shown on the saw housing, match. Refit the blade guard, protection plate and assemble the saw back to its mounting
BLADE SELECTION:
There are many different types of blades as well as steel and carbide tipped blades. Some of the more common types are described below.
CAUTION:
All blades must be rated at 5000rpm or higher, no larger than 254mm and have a bore size of 15.88mm (5/8").
COMBINATION BLADE:
The general purpose blade.Works well on most applications, but is rough cutting.Good choice for hardboard and man-made board.
CROSS CUT BLADE:
Designed primarily for cross cutting.Finer than a combination blade.
RIP BLADE:
Used for ripping. Especially good for thick materials.Very rough finish when used for cross cutting.
CARBIDE TIPPED BLADES:
Stay sharp much longer, but can cost more. Available in all types (See optional accessories on page 14). Since carbide is brittle, do not use on any material which may contain nails or screws,etc.
ABRASIVE BLADES AND METAL CUTTING BLADES:
DO NOT USE! This saw is NOT designed to cut metals or masonry materials. Doing so will invalidate the warranty and may result in injury.

CUTTING OPERATIONS
There are two basic types of cuts: ripping and cross cutting. In general,cutting with the grain is ripping and cutting across the grain is cross cutting. However, with man-made materials this distinction is somewhat different to make.Therefore, cutting a piece of wood to different width is ripping and cutting across the short dimension is cross cutting. Neither ripping or cross cutting maybe done safely freehand! Ripping requires the use of a rip fence and cross cutting the use of a mitre gauge.
CAUTION: Before using the saw each time check the following:-
1. Blade is tight.
2. Bevel angle locking knob is tight.
3. If ripping, that the fence locking knobs are tight and the fence is parallel to the table grooves.
4. If cross cutting,mitre gauge locking knob is tight.
5. Guard is in place and functioning properly.
6. Safety goggles, ear defenders and dust mask are being worn. Failure to adhere to these common safety rules can greatly increase the danger of injury.
Now that you have properly mounted your saw to a suitable bench or stand and have carefully completed the mechanical alignment of the various components, it is time to become familiar with it’s operation. The best way to do this is to recheck your mechanical alignments operationally. Before proceeding with these operational checks it is recommended that you read and understand the Ripping and Cross Cuttingsections on page 12.
You will require several pieces of clean smooth and straight scrap wood 50x100x600mm approximately.
1. Set the saw blade at 0° and blade height to approximately 53mm above the table surface. Be sure the blade angle adjustment lock knob is locked before operating the saw. Set your mitre gauge to 90° and place in a table slot on one side of the saw blade.Cross cut approximately 50mm off the end of a workpiece as shown in Fig.18.
Now make the following checks on the workpiece with a combination square:
a. CHECK SQUARENESS OF THE CUT ACROSS THE 50mm
THICKNESS (FIG.15):
1. If cut is not exactly 90° this means that the 90° positive stop in the table is not properly set.
2. Readjust the 90° end stop.
3. Repeat cross cuts and adjustments until you are satisfied that the 90° stop and pointer are correct.
b. CHECK SQUARENESS OF THE CUT ACROSS THE 100mm
WIDTH (FIG.16):
1. If cut is not exactly 90° this means that the mitre gauge 90° setting is wrong.
2. Readjust the mitre gauge 90° setting.
3. Repeat checking cross cuts and adjustments until satisfied mitre gauge setting is absolutely correct.
2. Now remove the mitre gauge from the table and clamp the rip fence on the table approximately 90mm on the right hand side of the blade. Leave the blade at 0° tilt and 53mm height as was for the previous checks. Make a rip cut as shown in (Fig.17) and make the following observations during the cutting.
a. WAS THERE ANY BINDING ON THE BLADE PRIOR TO THE CUT STRADDLING THE RIVING KNIFE?
1. If so, this means that the blade and rip fence are not absolutely parallel.
2. To correct this, first check that the rip fence is parallel to the blade in accordance with Fig.5.
3. Re-adjust rip fence if necessary and repeat rip cuts and adjustment until satisfied it is correct.
4. If the rip fence was not the problem, then the next step is to check the parallelism of the blade to the mitre gauge slot.
5. Readjust blade if necessary.
6. Make additional rip cuts and adjustments until satisfied there is no longer a blade binding problem. NOTE: If an adjustment was made to the blade, then repeat cross cut checks above.
b. WAS THERE ANY BINDING ON THE BLADE AND/OR RIVING KNIFE AS THE RIP CUT STRADDLED THE RIVING KNIFE?
1. If so, readjust the riving knife alignment to the blade.
2. Repeat rip cuts and realignment until satisfied no binding remains.
3. With the saw blade at zero tilt, approximately 53mm high and the blade angle adjustment knob locked, clamp and rip fence on the right hand side of the table and pointer as exactly 75mm on the rip scale. Make a rip cut on the workpiece.
Measure the width of the workpiece; it should be exactly 75mm.
1. If not 75mm, readjust the pointer.
2. Repeat rip cuts and readjustment of pointer until workpiece width is exactly 75mm. NOTE: Different types of blades make different kerfs (width of cuts), therefore it is necessary to check the adjustment of the rip fence pointer when changing blades.

CUTTING OPERATIONS
RIPPING (Fig.17):
Secure the rip fence to the table (see Fig.4,page 8).
Remove the mitre gauge.
Raise the blade so it is 53mm high.
Hold the work piece flat on the table and against the fence. Keep the work piece about 25mm from the blade.
CAUTION: The work piece must have a straight edge against the fence and must not be warped, twisted or bowed in any way. Keep both hands away from the blade and away from the path of the blade.
Turn the saw on and allow the blade to run up to full speed.
Keeping the work piece against the table and fence, slowly feed the work piece towards the saw blade. Stand with your body to one side of the blade and at the front of the table when feeding the wood.This will reduce the risk of injury should a piece of wood kickback or kick up.Continue pushing the work piece until it is clear of the guard and it falls off the rear of the table. Do not overload the motor. Never try to pull a work piece back with the blade turning. Turn the switch off, allow the blade to stop and raise the anti­kickback pawls on each side of the riving knife if required and slide the work piece out.
BEVEL RIPPING:
This operation is the same as ripping except that the blade angle is set to an angle other than the 0°.
WARNING:
ONLY WORK WITH THE WORK PIECE AND RIP FENCE ON THE RIGHT SIDE OF THE BLADE.
CROSS CUTTING (Fig.18.):
Remove the rip fence and place the mitre gauge in the table slot.
Set the blade height 53mm above the top of the work piece top.
Hold the work piece firmly against the mitre gauge with both hands.
Start the saw and allow the blade to spin up to full speed.
Whilst gripping the work piece firmly against the gauge and pushing flat against the table, slowly slide the wood through the blade.
BEVEL CROSS CUTTING (Fig.19):
This operation is the same as cross cutting except that the blade angle is set to an angle other than the 0°.
WARNING:
ONLY WORK WITH THE WORKPIECE AND MITRE ON THE RIGHT SIDE OF THE BLADE.
RIPPING SMALL PIECES OF WOOD (Fig.20):
This is an unsafe practice and not recommended. It is not safe to have your hands close to the blade. Instead, rip a large piece of material to obtain the desired size.When a small piece requires ripping use the push stick provided to hold the work piece in place,keeping your hands away from the blade.

CUTTING OPERATIONS
MITRE CUTTING (Fig.21):
This operation is the same as cross cutting except the mitre is locking at any angle other than 90°.
COMPOUND MITRE CUTTING:
This is a combination of bevel cross cutting and mitre cutting. It is very infrequently used. Follow the instructions for both mitre cutting and bevel cross cutting.
Fig.21.
MAINTENANCE
CHECKING THE BLADE PARALLELISM (Fig.22):
This check should be carried out before each use and adjusted if necessary
Ensure the saw is switched off and the plug is removed from the power supply. Using a steel ruler (Draper Stock No.12614),measure the distance✪✌ and the distance ✫✌. If the two distances differ, the blade is not completely parallel and requires adjusting.
ADJUSTING THE BLADE PARALLELISM (Fig.23):
This can be quite a confined adjustment. If difficulty is encountered, have a qualified Draper repair agent carry out the work.
Loosen ✬✌, ✭✌, ✮✌, ✯✌ and ✰✌ screws and nuts. Adjust the blade and remeasure once all the fixings have been secured.
When complete and before carrying out any test cuts, ensure all the fixings are tight.
