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 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 to position “0”.
Varying the speed
1.You can use the variable speed dial 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 tools and higher speed for smaller tools.
Holding the tool
•Small milling cutters/grinders pencils - high speed
•Large milling cutters/grinders pencils - low speed
1.For jobs such as milling or engraving where precision is required, hold the mini-drill 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.Locate the disc holder in the Collet nut.
2.Remove the screw from the end with the 2 in one wrench provided, and insert the screw through the cutting disc.
3.Replace the screw and tighten, attaching the cutting disc onto the holder. (Do not over-tighten)
Locating a sanding drum
1.Loosen the small screw in the top of the holder.
2.This allows the rubber to slacken.
3.Slide the sanding drum onto the holder.
4.Secure the sanding drum in place by tightening the screw causing the rubber drum to bulge and grip the drum. (Do not over-tighten)
