Adjusting the speed
The speed can be adjusted to
suit the material being sanded.
To adjust the speed, move the
variable speed control (5) until
you are satisfied that the speed
is what you need for the job
in hand.
Adjusting the auxiliary handle
The sander has two handles, the main handle (6) with
rubber grip and the auxiliary handle (1) which can be
adjusted to suit the operator’s needs.
1. To adjust the auxiliary
handle (1) loosen the
auxiliary handle lock (2)
enough so that you can
easily move the handle into
the desired position.
2. Re-tighten the auxiliary
handle lock (2).
Selecting the right grade of sandpaper
• 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. Always ensure that the tool is switched
off and the plug is removed from the power point before
making any adjustments or maintenance procedures.
