Using the sander

1.The sander is designed for sanding wood, plastic and similar materials. It can be used for sanding back and finishing the surface.

2.This sander is a handy size for medium jobs.

3.Wear safety goggles, a dust mask and ear defenders.

4.The whole sanding pad must rest on the workpiece.

5.Switch the sander on while it is off the workpiece and move it over the surface to be smoothed in a circular motion.

6.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 sander parallel to the work.

7.Use moderate pressure only, enough to control the machine without labouring the motor.

TIP. When sanding a rough or painted surface, start off with a course grit and work your way through to a finer one until the desired finish is achieved.

8.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.

To maximise the life of the motor do not use the sander continuously for more than 10-15 min at a time. Allow 5-10 min rest period between usage.

The manufacturer recommends the use of a residual current device with a tripping current of 30mA or less.

Selecting the right grade of sandpaper

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.

Different grades of sanding paper can be purchased from your local hardware store. Available grades are: Coarse, Medium and Fine.

Use a coarse grit to sand down rough finishes, medium grit to smooth the work and fine grit to finish off.

It is best to make a trial run on a scrap piece of material to determine the optimum grades of sandpaper for

a particular job. 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 same sanding sheet for wood and metal. Metal particles become embedded in the sandpaper and will scour a wooden surface.

Using the hole punch

If the sandpaper installed does not have holes it will be necessary to punch holes into the sandpaper using the hole punch (10) provided.

Place the hole punch on a level surface.

After fitting the sandpaper to the sander align the base of the sander with the hole punch and push down on the sander until the hole punch pierces the sandpaper.

Remove the sander from the hole punch.

TIP: Depending on the paper used, you may need to use a pointed screwdriver to open and clear the holes to increase the efficiency of dust extraction.
