Children and infirm people must not use this tool. Children  
should be supervised at all times if they are in the area in  
which the tool is being used. It is also imperative that you  
observe the accident prevention regulations in force in your  
area. The same applies for general rules of occupational  
health and safety.  
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.  
WARNING. When using power tools, basic safety  
precautions should always be taken to reduce the risk of fire,  
electric shock and personal injury. Also, please read and heed  
the advice given in the additional important safety instructions.  
LASER LIGHT. LASER RADIATION  
Do not stare into beam.  
1. Keep the work area clean and tidy. Cluttered work  
areas and benches invite accidents and injury.  
Only turn laser beam on when tool  
is on work piece. Class 2 laser product  
2. Consider the environment in which you are working.  
Do not use power tools in damp or wet locations. Keep  
the work area well lit. Do not expose power tools to rain.  
Do not use power tools in the presence of flammable  
liquids or gases.

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.  
13. Disconnect idle tools. Switch off the power and  
disconnect the plug from the power point before  
servicing, when changing accessories and when the  
tool is not in use.  
14. Remove adjusting keys and wrenches.  
Check to see that keys and adjusting wrenches  
are removed from the tool before switching on.  
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.  
15. Avoid unintentional starting. Always check that the  
switch is in the OFF position before plugging in the tool  
to the power supply. Do not carry a plugged in tool with  
your finger on the switch.  
This scroll saw is intended for indoor use only.  
16. Use outdoor rated extension cords. When a tool  
is used outdoors, use only extension cords that are  
intended for outdoor use and are so marked.  
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.  
Wear safety goggles  
Wear ear protection  
Wear a breathing mask  
Never turn your scroll saw on before clearing the  
table of all objects (tools, scraps of wood, etc.) except  
for the workpiece.  
Accessories  
The GMC LS1620 Scroll Saw is supplied with the following  
accessories as standard:  
Avoid awkward hand positions where a sudden slip could  
cause a hand to move into the blade.  
15 TPI saw blade  
18 TPI saw blade  
Allen key  
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.  
Instruction manual  
Always adjust blade tension correctly.  
Unpacking  
The scroll saw should cut on the down stroke. Always  
make sure blade teeth are oriented downward towards  
the table.  
Due to modern mass production techniques, it is unlikely  
that your GMC Power Tool is faulty or that a part is missing.  
If you find anything wrong, do not operate the tool until the  
parts have been replaced or the fault has been rectified.  
Failure to do so could result in serious personal injury.  
When cutting a large piece of material make sure it is  
supported at table height.  
Hold the work firmly against the table.  
The scroll saw you have purchased is ideal for numerous  
projects including making toys, puzzles, games, artwork  
and jewellery, and due to its cutting capacity is a handy  
do-it-yourself tool. It cuts wood up to 50mm thick as well  
as plastics.  
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.  
Assembly  
The GMC Scroll saw is packed fully assembled.  
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.
