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 on/off switch (4) forward to start the motor.
3. Pull the on/off switch (4) back to stop the motor.
4. Hold the tool securely and make sure that you have full
control at all times.
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 two interchangeable bases: a 150mm base
(3) fitted to the tool on purchase and a 125mm base (10)
supplied with the tool as an accessory.
1. Turn the sander upside
down and remove the four
hex screws using the hex
key (9) provided. Take off the
base assembly.
2. Place the replacement base
assembly on the tool and
secure it with the 4 hex screws
using the hex key (9) supplied.
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 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.
Tip. To maximise the life of the hook and loop base peel
the paper off slowly rather than rapidly removing it to avoid
damage to the hook and loop system.
CAUTION. Take care to regularly clean out the build up of
dust on the base underneath the sandpaper and not to let
the sandpaper wear completely down before replacing it.
Failure to observe these two precautionary measures can
lead to damage to the hooks and loops on the platen and
the sandpaper will not attach properly.
WARNING. Never use the sander unless the entire base
is fitted with sandpaper or another type of pad.
Using the sander
1. Grip the main handle (6) in one hand and push down on
the auxiliary handle (1) 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. 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.
WARNING. Do not use the sander in wet or damp conditions.
The manufacturer recommends the use of a residual current
device with a tripping current of 30mA or less.
