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

Connect the plug to the

power supply.
Pull the on/off trigger (2) upward

to start the sander. (Fig.A)
Release the trigger to turn off

the sander.
By pulling the trigger on and

pressing the lock on button (3),

you can lock the sander on.

Pulling the switch on again and

releasing it turns the switch off.

(Fig. B)

Using the sander

The sander is designed for

sanding wood, metal, plastic and

similar materials. It can be used

for sanding back and finishing the surface.
This sander is a handy size for medium jobs.

WARNING.

Wear safety goggles, a dust mask and

ear defenders.The whole sanding pad must rest on

the workpiece.
Switch the sander on while it is placed on the workpiece

and move it over the surface to be smoothed in a

circular motion.
Grip the main handle (4) in one hand and push down on the

front of the handle with the other hand.
Take care to hold the sander parallel to the work.

Use moderate pressure only.

If there are still marks on your work after sanding, try either

going back to a coarser grade and sanding the marks out

before recommencing with the original choice of grit, or try

using a new piece of sandpaper to eliminate the unwanted

marks before going on to a finer grit and finishing the job.

WARNING.

Do not use the sander in wet or

damp conditions.

Fitting a sanding sheet

CAUTION.

Switch off the sander and disconnect it from the

power point.
With hook & loop type sanding

sheets, simply press the sheet

to the platen (7), taking care to

align the holes in the sanding

sheet with those in the platen.

(Fig. C)
Ordinary (non-hook & loop type)

sanding sheets can also be

used. Release the clamps (8)

from both sides of the sander.

(Fig. D)
Insert the end of the sandpaper

under the front clamp and pull

the paper tight over the platen

ensuring the holes align with

those in the platen and then

clamp the other end.
The paper should be kept

tightly clamped over the platen, otherwise there could be

excessive wear of the

cushion material.

WARNING.

Do not continue to use the sander with a

sanding sheet that is overworn or damaged.

WARNING.

Do not use the same sanding sheet for wood

and metal. Metal particles become embedded in the

sandpaper and will scour a wooden surface.
