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.
The manufacturer shall not be liable for any changes made to the tool nor for any damage resulting from such changes.
Even when the tool is used as prescribed it is not possible to eliminate all residual risk factors. The following hazards may arise in connection with the tool’s construction and design:
•Damage to the lungs if an effective dust mask is not worn.
•Damage to hearing if effective earmuffs are not worn.
•Damage to eyes if effective goggles are not worn
•Risk of injury unless hands are kept well clear of cutting devices
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.
Operation
WARNING. Before connecting a tool to a power source (power point receptacle, outlet, etc.) be sure that the voltage supply is the same as that specified on the nameplate of the tool. A power source with a voltage greater than that specified for the tool can result in serious injury to the user, as well as damage to the tool. If in doubt, do not plug in the tool. Using a power source with a voltage less than the nameplate rating is harmful to the motor.
Switch on
1.Set the variable speed dial (4) to 1 and push the on/off switch (3) to “I”, the machine is in continuous operation, and will start at minimum speed.
Switch off
1.Reset the variable speed dial (4) to 1 and push the on/off switch (3) to position “0”.
Varying the speed
1.You can use the variable speed dial (4) to alter the speed of the collet, as follows:
•Position 1 - Slow
•Position 3 - Medium
•Position 6 - Fast
2.Select the correct speed for the work and type of bit you are using. In general, lower speeds are best suited for large accessories and higher speed for smaller accessories.
Quick reference guide

• | Removing rust | 3 - 4 |
• | Sharpening | 3 - 4 |
• | Polishing | 1 - 2 |
Holding the tool
1.For jobs such as milling or engraving where precision is required, hold the tool like a pen.
2.For heavier work like cutting or grinding hold the machine in the palm of your hand.
Changing accessories
1.Make sure that the machine is switched off and the plug removed from the power before you commence changeover.
2.Loosen and tighten collet fully using the 2 in 1 wrench provided. (always ensure bits are tight before commencing any work with your tool).
3.Press and hold down the spindle lock button (5) and unscrew the Collet nut (6).
4.Select a suitable Collet for the accessory to be used and insert it in the collet nut shaft.
5.Turn the Collet nut in an anti-clockwise direction to loosen and, when the bit is in place, turn the Collet nut in clockwise direction to lock it in place, whilst depressing the spindle lock.
6.Make sure that the bit is inserted as far as possible. Having too much shaft exposed could cause it to damage or bend.
Locating a cutting/sanding disc
1.Insert the disc holder into the Collet (7) whilst the Collet nut (6) is loosened.
2.Remove the screw from the end of the disk holder with the 2 in 1 wrench provided, and insert the screw through the cutting/sanding disc.
3.Replace the screw and tighten, attaching the cutting or sanding disc onto the holder. (Do not over-tighten)
Locating a sanding drum
1.Loosen the small screw in the top of the holder (This allows the rubber to slacken).
2.Slide the sanding drum onto the holder.
3.Secure the sanding drum in place by tightening the screw causing the rubber drum to bulge and grip the drum. (Do not over-tighten)
Attaching the flexible shaft
WARNING. Never bend the flexible shaft with a radius of less than 150 mm (6”) when operating. Please store the flexible shaft in the designated compartment of the carry case when not in use.
1.Remove the collet cover (9), and loosen the collet nut (6) by turning them anti-clockwise.
2.Insert the inner cable of the flexible shaft into the collet
(7)until the cable cannot go any further.
3.Tighten the collet nut (6) with the wrench by turning the nut clockwise.
4.Thread the flexible shaft collet cover onto the tool housing by turning it clockwise, and finger tighten only.
WARNING. Never tighten the collet nut with the use of pliers or a wrench as the thread will strip.
Changing the collet and accessories
Note. To change the collet or install a cutter or accessory into the flexible shaft, follow the same general procedure as covered earlier under ‘Changing accessories’.
WARNING. Do not attempt to loosen the collet nut without pulling the spindle lock back as far as possible. Damage to the flexible shaft will result.
1.To lock the spindle lock, pull the lock back as far as possible.
2.Use the wrench to loosen and tighten the collet nut.

1.Store the machine, instruction manual and, where necessary, the accessories in the original packaging. In this way you will always have all the information and parts ready to hand.
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 rag.
3.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 tool.
