Safety rules for laser lights
The laser light/laser radiation used in the GMC REDEYE® system is Class 1 with maximum 1mW and 650nm wavelengths. These lasers do not normally present an optical hazard, although staring at the beam may cause flash blindness.
Warning. Do not stare directly at the laser beam. A
hazard may exist if you deliberately stare into the beam, please observe all safety rules as follows;
The laser shall be used and maintained in accordance
with the manufacturer’s instructions.
Never aim the beam at any person or an object other
than the work piece.
LASER LIGHT. LASER RADIATION
Do not stare into beam.
Only turn laser beam on when tool
is on work piece. Class 1 laser product
The laser beam shall not be deliberately aimed at
personnel and shall be prevented from being directed towards the eye of a person for longer than 0.25s.
Always ensure the laser beam is aimed at a sturdy work
piece without reflective surfaces. i.e. wood or rough coated surfaces are acceptable. Bright shiny reflective sheet steel or the like is not suitable for laser use as the reflective surface could direct the beam back at the operator.
Do not change the laser light assembly with a different
type. Repairs must only be carried out by the laser manufacturer or an authorised agent.
CAUTION: Use of controls or adjustments or performance
of procedures other than those specified herein may result in hazardous radiation exposure.
Please refer to the relevant Australian standards, AS 2397 and AS/NZS2211 for more information on Lasers.

Additional safety rules for scroll saws
Do not alter or misuse the tool. These tools are
precision built. Any alteration or modification not specified is misuse and may result in dangerous conditions.
For your own safety, do not operate your scroll saw until
it is completely assembled and installed according to the instructions and until you have read and understood all of the instructions.
Your scroll saw must be bolted securely to a stand or
work bench. In addition, if there is any tendency for the scroll saw to tip over or move during certain operations, such as cutting long, heavy boards, bolt your scroll saw stand or workbench to the floor.

This scroll saw is intended for indoor use only.
To avoid being pulled into the blade, do not wear loose
fitting gloves, loose clothing, neck ties or jewellery. Tie back long hair and roll long sleeves above elbows.
Do not cut pieces too small to hold by hand. When
making a small cutout always secure the workpiece to a scrap piece of plywood with double sided tape. This way the work is supported and your fingers are away from the blade.
Never turn your scroll saw on before clearing the table
of all objects (tools, scraps of wood, etc.) except for the workpiece.
Avoid awkward hand positions where a sudden slip
could cause a hand to move into the blade.
Always adjust the drop foot to just clear the workpiece
to protect the operator, keep blade breakage to a minimum and provide maximum support for the blade.
Always adjust blade tension correctly.
The scroll saw should cut on the down stroke. Always
make sure blade teeth are oriented downward towards the table.
When cutting a large piece of material make sure it is
supported at table height.
Hold the work firmly against the table.
Do not feed the material too fast while cutting. Only
feed the material fast enough so that the blade will cut.
Use caution when cutting off material which is irregular
in cross section as it could pinch the blade before the cut is completed. A piece of moulding, for example, must lay flat on the table and not be permitted to rock whilst being cut.
Use caution when cutting off round material such as
dowel rods or tubing. They have a tendency to roll while being cut causing the blade to bite.
Never leave the scroll saw running unattended. Always
turn the saw off, make sure that it has come to a complete stop, and then remove plug from the power
supply before leaving the work area.
Do not perform layout, assembly or setup work on the
table while the cutting tool is operating.
Turn saw off and remove plug from power supply outlet
before installing or removing blades.
Wear safety goggles Wear ear protection Wear a breathing mask

Mounting the saw to a workbench
It is recommended that the scroll saw is secured to a work bench to gain maximum stability and prevent noise and vibration.
1. Using the base of the scroll saw as a template mark the holes on the workbench through the holes in the casting.
2. Drill the holes through the workbench using an 8mm drill bit.
3. Bolt the saw to the workbench using bolts, washers and nuts.
Note. The fasteners are not supplied with the machine. Note. A soft foam pad or carpet (not supplied) can be
placed between the scroll saw and the work bench to further reduce noise and vibration.
Blades
The scroll saw accepts 127mm pin type and flat blades. A flat blade adapter is not required.
Selecting the correct blade
1. The scroll saw accepts a wide variety of blade widths and thicknesses for cutting wood and other wood based materials.
2. The blade width, thickness, and number of teeth per inch will be determined by the material and size of the radius being cut.
3. Select a blade that allows at least three (3) teeth to be in contact with the workpiece at all times.
4. Very fine, narrow blades should be used for curve cutting in thin wood (6mm or less).
5. To cut thicker wood, use wider blades with fewer teeth per inch.
6. When cutting wood thicker than 25mm, guide the workpiece into the blade slowly and take care not to bend or twist the blade whilst cutting.
7. Most blade packages state the size or thickness of wood which that blade is intended to cut, and the radius (size of curve) which can be cut with that blade.
8. Wider blades cannot cut curves as tight or small as thinner blades.
9. This saw uses 127mm long pin type and flat blades.
10. Blades wear faster when:
a. Cutting plywood which is very abrasive b. Cutting wood that is thicker than 19mm c. Cutting hardwood d. Side pressure is placed on the blade
Removing blades
Caution. Always ensure that
the saw is switched off and unplugged from the mains supply before removing or installing a blade.
1. Lift up the blade tension lever (12) to reduce the blade tension.
2. Remove the table insert (11) by raising it with a screwdriver.
3. Loosen the upper and lower blade adapter knobs (14)
4. Remove blade from the upper and lower blade adapters (13).

Installing blades
Caution. Always ensure that the saw is switched off and
unplugged from the mains supply before removing or installing a blade.
1. Lift up the blade tension lever (12) to reduce the blade tension.
2. Remove the table insert (11) by raising it with a screwdriver.
3. Loosen the upper and lower blade adapter knobs (14). Ensure that the slots on the upper and lower blade adapters are wider than the thickness of the blade.
4. In order to cut effectively and avoid uncontrollable lifting of the workpiece, the teeth of the scroll saw blade must always point in a downward direction.
5. Insert the blade in the lower blade adapter and tighten the blade adapter knob.
6. Press the upper arm down and insert the top part into the upper blade adapter and tighten the blade adapter knob.
7. Lower the blade tension lever to secure the blade in position.
8. If the tension is too tight
when lowered, lift the blade tension lever back up and turn it in an anti-clockwise direction to loosen the blade tension.
9. If the tension is too loose when lowered, lift the blade tension lever back up and turn it in a clockwise direction to tighten the blade tension.
10. Replace the table insert.
Setting the table for horizontal or bevel cutting
Caution. Always ensure that the saw is switched off and
unplugged from the mains supply before making any adjustments.
1. Loosen the table lock knob (17) to allow the saw table to be tilted to the left and right. The table can be locked at any angle from a 0º horizontal cutting position up to a 45º angle both to the left and right for bevel cutting.
2. A bevel adjustment scale (16) is positioned under the work table to assist in setting the appropriate table angle for bevel cutting. When greater precision is required, make a practice cut first and then adjust the table as necessary for your requirements.
Note. When bevel cutting, the drop foot (8) can be
tilted so it’s parallel to the table and rests flat against the workpiece. To tilt the drop foot, loosen the Allen screw at the front of the drop foot assembly and then tilt the foot so that it’s parallel to the table, re-tighten the Allen screw to secure the drop foot in place.
Page 10

Aligning the degree scale pointer
1. Loosen the table lock knob (17) and position the table so that it is at a right angle to the blade.
2. Place a small square on the table next to the blade to check if the table is at a 90º angle to the blade. If adjustment is needed, change the bevel angle until the table is at approximately 90º to the blade and securely tighten the table lock knob.
3. Loosen the 2 screws holding the degree scale pointer and move the pointer to the 0º position. Securely tighten the screws.
Note. The degree scale is a convenient guide but should
not be relied upon for precision. Always make a practice cut in scrap wood to determine if your angle settings are correct.
Turning on and off
1. To turn on the scroll saw lift the on/off switch (1).
2. To turn off the scroll saw push the on/off switch (1) down.
Adjusting the sawdust blower
Your scroll saw features a sawdust blower (6) to help keep the work area clean for more accurate scroll cuts. For best results always direct air flow from the blower tube at the blade and workpiece.
1. To adjust move tube to the correct position.
Adjusting the LED light
The LED light will illuminate the work area for greater visibility of the cutting line.
1. To turn on the LED light press the LED light button (3) on the control panel.
2. To adjust the direction of the light move the tube to the most suitable position.
Note. The LED light will not function if the saw is not in
the ‘on’ position.

Adjusting the laser line
1. To adjust the laser beam first turn on the scroll saw using the on/off switch (1)
2. To adjust the laser line turn the laser line alignment knob (5) in an anti-clockwise direction to loosen it and then move it to the left or right until the laser line is in line with the blade. Turn the laser line alignment knob (5) in a clockwise direction to tighten it.
3. Turn off the scroll saw
Adjusting the speed
The speed can be adjusted to suit the work piece being cut. The variable speed dial (1) is located at the top of the saw for convenient adjustment of the speed.
1. Turn the saw on by lifting the on/off switch (1).
2. Turn the dial in a clockwise direction for a faster speed and in an anti-clockwise direction to reduce
the speed.
3. Determine the optimum speed by making a trial cut in a scrap piece of material.
Note. Using the correct speed for the job increases the
life of the saw blade.
Selecting the correct speed
The below table shows the most appropriate blade and speed to be used for different materials and applications.
Scroll saw operation
1. Ensure that the table insert is in place and flush with the table.
2. To start the saw lift up the on/off switch (1).
3. Adjust the speed to suit the work piece being cut.
4. To begin the cut guide the wood into the moving saw blade, the blade teeth cut only on the down stroke.

5. The saw will not cut wood by itself, you allow the saw to cut wood by guiding the wood into the blade as it moves.
6. The drop foot (8) should always be lowered until it just rests on top of the work piece to prevent your work piece from lifting during operation but not so much that the workpiece drags. To lower or raise the drop foot loosen the drop foot locking knob (9) and position the drop foot so it rests on top of the work piece. Retighten the drop foot locking knob.
6. Ensure that you feed the wood into the blade slowly because the teeth of the blade are very small and they can only remove wood when they are on the down stroke.
7. The blade will flex backwards when applying feed pressure. Too much feed pressure will cause blade breakage.
8. Best results are achieved when cutting wood less than 25mm thick.
9. When cutting wood thicker than 25mm, the user must feed the wood into the blade very slowly, increase blade tension and take extra care not to bend or twist the blade while cutting in order to maximise blade life.
10. Teeth on scroll saw blades wear quickly and as a
result must be replaced frequently for best cutting results. Scroll saw blades generally stay sharp for 30 minutes to 2 hours of cutting.
11. Once finished push the on/off switch down to turn
off the saw and unplug the tool from the power point to prevent unauthorised use.
Locking the scroll saw
The on/off switch features a locking peg that can be used to help prevent unauthorised use.
1. Slide a padlock through the locking peg and engage it, this will prevent the on/off switch from being lifted when the tool is left unattended.
Using the REDEYE® laser line generator system
Warnings. Do not stare directly at the laser beam.
Never aim the beam at any person or an object other than the work piece.
Do not deliberately aim the beam at personnel and ensure that it is not directed towards the eye of a person for longer than 0.25s.
Always ensure the laser beam is aimed at a sturdy work piece without reflective surfaces, i.e. wood or rough coated surfaces are acceptable. Bright shiny reflective sheet steel or the like is not suitable for laser use as the reflective surface could direct the beam back at the operator.
1. Mark the line of cut on the work piece.
2. To start the saw lift up the on/off switch (1).
3. Adjust the speed to suit the work piece being cut.
4. Switch on the laser beam using the laser light on/off switch (2).
5. Line up the laser line with the line on the work piece
6. To begin the cut guide the wood into the moving saw blade.
7. Switch off the laser beam on completion of the cut.
8. Once finished push the on/off switch down to turn off the saw and unplug the tool from the power point to prevent unauthorised use.

Maintenance
Warning. Always ensure that the tool is switched off
and the plug is removed from the power point before making and adjustments or maintenance procedures.
An occasional coat of paste wax on the work table will allow the wood being cut to glide smoothly across the work surface.
Oiling the arm bearings
The saws arm bearings should be lubricated after every 50 hours of use. Ensure plug is removed from the mains power supply.
1. Turn the saw on its side.
2. Squirt a generous amount of SAE 20 oil around the shaft end and bronze bearings.
3. Let the oil soak in overnight in this position.
4. Next day repeat the above procedure for the opposite side of the saw.
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 brush or a rag.
3. Re-lubricate all moving parts at regular intervals.
4. Never use caustic agents to clean plastic parts.
Caution. Do not use cleaning agents to clean the plastic
parts of the tool. A mild detergent on a damp cloth is recommended. Water must never come into contact with the saw.
