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.

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.
Maintenance
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.
Repairs
1. Only an authorised service centre should replace the
cordset or effect other repairs. If the cordset is damaged
or worn, have it repaired or replaced by an authorised
service centre.
2. When the brushes are worn, the tool may not work.
Have new brushes fitted by an authorised service centre.
