Safety instructions  
To use this tool properly, you must observe the safety  
regulations, the assembly instructions and the operating  
instructions to be found in this Manual. All persons who  
use and service the machine have to be acquainted with  
this Manual and must be informed about its potential  
hazards. 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. 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.  
Your GMC power tool has many features that will make  
your job faster and easier. Safety, performance, and  
dependability have been given top priority in the  
development of this tool, making it easy to maintain  
and operate.  
Environmental protection  
Recycle unwanted materials instead of  
disposing of them as waste. All tools, hoses  
and packaging should be sorted, taken to  
the local recycling centre and disposed of  
in an environmentally safe way.  
1. Keep the work area clean and tidy. Cluttered work  
areas and benches invite accidents and injury.  
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.  
3

Do not expose power tools to rain and high humidity.  
Do not use power tools in the presence of flammable  
liquids or gases.  
3. Keep visitors away from the work area. All visitors  
and onlookers, especially children and infirm persons  
should be kept well away from where you are working.  
Do not let others in the vicinity make contact with the  
tool or extension cord.  
13. Look after your tools. Keep tools clean and sharp for  
better and safer performance. Follow the instructions  
regarding lubrication and accessory changes. Inspect  
tool cords periodically and, if damaged, have them  
repaired by an authorised service facility. Inspect  
extension cords periodically and replace them if  
damaged. Keep tool handles dry, clean and free from  
oil and grease.  
14. 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.  
15. Remove adjusting keys and wrenches. Form the  
habit of checking to see that keys and adjusting  
wrenches are removed from the tool before switching  
it on.  
16. 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.  
17. 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.  
4. Store tools safely. When not in use, tools should be  
stored in a dry, high place or locked up out of the  
reach of children and infirm persons.  
5. Do not force the tool. The tool will do the job better  
and safer working at the rate for which it was  
designed.  
6. Use the correct tool for the job. Do not force small  
tools or attachments to do the job best handled by a  
heavier duty tool. Never use a tool for a purpose other  
than that for which it was intended.  
7. Dress correctly. Do not wear loose clothing or jewelry.  
They can be caught in moving parts. Rubber gloves and  
non-slip footwear are recommended when working

should always be worn. A face or dust mask is also  
required.  
19. Check for damaged parts. Before using a tool, check  
that there are no damaged parts. If a part, such as a  
guard is damaged, carefully determine if it will  
operate properly and perform its intended function.  
Check for alignment of moving parts, binding of  
moving parts, breakage of parts, proper mounting and  
any other conditions that may affect the operation of  
the tool. A guard or other part that is damaged  
should be properly repaired or replaced by an  
9. Connect dust extraction equipment. If devices are  
provided for the connection of dust extraction and  
collection facilities, ensure that these are connected

3. Position the table so that the  
trunnion rests in the groove on  
the side of the frame.  
4. Fasten the table to the frame  
using the lock handle.  
NOTE. To loosen the table, push

Unpacking  
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.  
Mounting  
1. It is best to attach the band saw to a firm, stable  
surface at a convenient working height. A work bench  
is ideal.  
2. Drill four 12 mm holes in the work bench to match the  
four holes in the base of the saw.  
3. Attach the band saw to the work bench using 8 mm  
screws (inserted from the top), lock washers and nuts.  
6. Insert the table insert.  
7. Position the fence on the  
table, slide it to the desired  
location and turn the fence  
handle to lock the fence in  
position.  
8. If required, add the protractor  
guide to one of the channels  
in the table.  
Assembly  
The Band Saw is shipped partly disassembled and the saw  
table and rip fence have to be installed prior to use.  
1. Attach the trunnion to the  
underside of the table using  
the two screws, two washers  
and two spring washers  
supplied.  
2. Place the table onto the saw  
frame, threading the saw  
blade through the slot in  
the table.

WARNING. Over tightening the band saw will cause  
premature failure. Under tightening can cause the band to  
disengage whilst it is in use.  
Setting the cutting height  
1. Always set the upper blade  
guide assembly as close as  
practical to the work.  
2. To adjust the height, loosen the  
lock knob on the lamp side of  
the upper wheel housing, set  
the guide as required and then  
re-tighten the lock knob.

1. Use the Allen key to loosen  
the screw either side of the  
upper blade guide assembly.  
2. Slide the assembly left or  
right so that the blade is  
in the centre of the  
two bearings.  
3. Slide the assembly back or  
forward so that the rear  
bearing is just clear of the back of the blade.  
4. Retighten the two adjustment screws.  
5. The bearings should run freely and turn when the  
saw is in use.  
6. Use the Allen key to loosen the adjustment screw on  
the side of the lower support head. This screw is  
accessed through a hole in the frame.  
7. Set the rear bearing just clear of the back of the blade.  
8. The bearings should run freely and turn when the saw  
is in use.  
NOTE. Do not set the bearing too close, as the resulting  
friction will generate heat, which can have an adverse  
affect on the bearings and the blade. The bearing should  
run freely and turn when the machine is in use.  
Saw table tilt  
1. To tilt the table, loosen the  
table lock handle on the  
underside of the table, tilt the  
table to the required angle and  
retighten the handle.
