OPERATING INSTRUCTIONS
This sander is a hand-held class II electric power tool. It is driven by single-
phase series motor and is double insulated. The work to be sanded must be
secure: If it is small or it may move during sanding, it must be held in a vice or
suitably clamped.
This sander is designed for dry sanding only. It is suitable, using the correct
accessories for the following work:
Surface sanding on wood, metal, plastic and filler surfaces.
•
Switch
on
Connect the plug to socket, push switch forward.
•
Switch
off
Push switch back.
MOUNTING OF SANDPAPER SHEETS
Check that the machine is disconnected from the mains supply!
Open one sanding sheet clamp on the base plate and insert on the end of the
sanding paper into the correct position, close clamp. Place the paper on the
pad, making sure that the holes of pad and sandpaper are aligned. Then power
the second clamp and insert the other end of the abrasive paper then close
clamp. Check that the paper is firmly secured and that it completely covers the
base of the sanding pad.
WARNING:
•
Do not continue to use the sander with a sanding sheet that is over
worn or damaged.
•
Do not use the same sanding sheet for wood and metal. Metal
particles become embedded in the sandpaper and will scour a
wooden surface.
•
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 sanding pad and
the sandpaper will not attach properly.
SELECTING THE RIGHT GRADE OF SANDPAPER
1. Different grades of sanding paper can be purchased from Argos. Available
grades are Coarse, Medium and Fine.
2. Use coarse grits to sand down rough finishes, medium grit to smooth the
work and fine grit to finish off.

3. Different types of abrasive paper will allow the sander to meet various
needs. Different grades of abrasive paper are available; the higher the
grade number, the finer the grit. For rough work start with a low grade of
grit. (e.g. 60 grit) and change to a higher, finer grade (e.g. 80 or 120 grit)
for finishing. If you use a fine grade for rough surfaces it will soon clog and
need changing.
4. 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.
SANDING
1. The sander can be used for most sanding operations on materials such as
wood, plastic, metal and painted surfaces.
2. Wear safety goggles, a dust mask and ear defenders.
3. Move the sander over the surface of the work in a circular motion with an
even, moderate pressure.
4. At all times, let the sander do the work-do not force it or apply excessive
pressure to the sanding paper or it could wrinkle or tear. Preferably, use a
light circular motion.
5. If the surface shows excessive marking from the abrasive motion, you may
be using a grit which is too coarse or applying too much pressure.
CAUTION:
•
Where possible, clamp smaller work pieces to the bench.
•
Do not use your sander on materials containing asbestos.
NOTE. If there are still scratches on your work after sanding, try either of
the following:
1. Go back to a coarser grit and sand the marks out before recommencing
with the original choice or,
2. Try using new sandpaper of the same grit to eliminate the unwanted marks
before progressing to a finer grit and finishing the job.
DUST EXTRACTION
For small areas of sanding, use the dust bag attached. When sanding large
areas, use a suitable vacuum cleaner to reduce the amount of dust.
Warning:
always disconnect form the power supply before cleaning or
maintaining.
WARNING:
•
Do not exert undue down-pressure when sanding. Too much pressure
