Switching On And Off; Using The Sander; Changing The Base; Fitting A Sanding Sheet - GMC 230W Instruction Manual

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.

Switching on and off

1. Connect the plug to the power supply.
2. Push the left-hand side "I" of the sealed on/off switch
(1) to start the motor.
3. Push the right-hand side "O" of the sealed on/off
switch (1) to stop the motor.
4. Hold the tool securely and make sure that you have full
control at all times.

Using the sander

1. Grip the rear of the handle (2) in one hand and push
down on the front of the handle with the other hand.
Take care to hold the sanding surface parallel to
the work.
2. Do not press down heavily. This will slow down the
motor and could damage it.
3. Let the sandpaper do the work.
4. When using the random orbital base (7), take care that
the whole base is resting on the workpiece when you
switch on the sander. After
switching off, keep the base
on the sander until the
motor stops.
5. When using the detail base
(6) and 1/3 sheet base
(8), switch the sander on
with the base away from
the workpiece. Let the motor reach full speed then
carefully begin sanding. Remove the sander form the
workpiece before switching off.
WARNING.
Do not use the sander in wet or damp
conditions.

Changing the base

WARNING. Always ensure that the tool is switched
off and the plug is removed from the power point before
making any adjustments or maintenance procedures.
There are three interchangeable bases:
• Detail base (6) – ideal for flat sanding and for reaching
into corners and along edges.
• Random orbital base (7) – designed to rapidly smooth
down large flat surfaces where the random action
helps prevent the occurrence of swirl marks and other
scratches.
• 1/3 Sheet base (8)
– for general sanding over
moderately-sized areas.
1. Remove the four hex fixing
screws (4) using the allen
key (5) provided.
2. Fit the base required for
the sanding operation
and replace the four
fixing screws (4), with the allen key provided.

Fitting a sanding sheet

WARNING.
Always ensure that the tool is switched
off and the plug is removed from the power point before
making any adjustments or maintenance procedures.
1. Before fitting sandpaper, remove any dust or debris
from the hooks and loops of the base.
2. Match the holes in a suitable sheet with the holes in
the base.
3. Simply press the sheet to the base to attach it.
4. To remove the sheet, peel it away from the base.
