Selecting The Right Grade Of Sandpaper; Dust Extraction; Maintenance - GMC SA186 Instruction Manual

8. The paper should be kept tightly clamped over the
base, otherwise there could be excessive wear of the
base material.
WARNING.
Never use the sander unless the entire base is
fitted with sandpaper or another type of pad.

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.

Dust extraction

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.
1. Attach the dust extraction
canister (3) to the sander
by pushing and twisting the
bayonet fitting in a similar
action to inserting a light globe into a lamp.
WARNING. For optimum dust extraction, remove and
empty the canister (3) when it is no more than half full.
Do not use the canister when sanding metal. The hot
metal particles could cause residual wood dust or the
internal bag itself to catch fire.
2. Remove the cap from the
end of the canister (3)
to access the internal bag
when you wish to replace or
clean the bag. The bag can
be washed. Make sure the
bag is completely dry before
replacing it.

Maintenance

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.
1. Keep the tool's air vents unclogged and clean at
all times.
2. Regularly check to see if any dust or foreign matter has
entered the grills near the motor and around the
on/off switch. Use a soft brush to remove any
accumulated dust. Wear safety glasses to protect
your eyes whilst cleaning.
3. If the body of the tool needs cleaning, wipe it with
a soft damp cloth. A mild detergent can be used but
nothing like alcohol, petrol or other cleaning agent.
4. Never use caustic agents to clean plastic parts.
CAUTION.
Water must never come into contact with
the tool.
5. Lubricate all moving parts at regular intervals.
