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.
