OPERATION INSTRUCTIONS
Getting Started
After making sure the power source
matches the specifications on the sander
label, plug in sander. Pull the trigger
switch to turn it on, and release the switch
to turn the sander off. When you first turn
it on, make sure that your finger remains
on the switch so you can STOP the
sander in case there’s a problem. The
sander should run smoothly. Strange or
unnatural noises should be investigated
and corrected before operating the
machine further.
Speed selection can be adjusted from the
dial on the On/Off switch. The label on the
switch indicates the direction needed to
increase or decrease speed.
Selecting Abrasives
The best results from your G9910 Hook &
Loop Sander/Poisher will be accom-
plished using the proper grit of coated
abrasive. As a rule, you will want to start
with a more coarse paper for removing
large defects or rough spots, then work
through finer grits one or two grades at a
time until you achieve the smoothness
and quality you desire.
Any time you are unsure about which grit
to begin with, experiment in a small corner
or area that isn’t very noticeable on your
project. Ideally, you want to achieve the
balance of removing defects without dam-
aging your work.
ALUMINUM OXIDE and SILICON CAR-
BIDE abrasives are an excellent choice
because they last longer and are sharper
than natural abrasives.
Attaching Abrasives
Abrasive sheets are easily attached with
the hook-and-loop system on the pad of
your G9910 sander. Fit the sheet over the
pad so that it covers the entire area, push
and slightly twist to make sure the coated
abrasive sheet is snug on the pad. Make
sure you don’t cover the suction holes.
Remove abrasive sheets by pinching an
edge and peeling off.
Using the Sander
Starting with the coarsest grit you have
determined to be sufficient for the job,
sand the work evenly, in the same direc-
tion as the grain of the wood. Always keep
the machine moving so the finish of your
work stays consistent. If you stay in one
place too long, then the sander may pro-
duce a depression in the wood that will
compromise your finish.
Sanding across the grain of the wood may
be necessary in some cases to remove
rough defects. This should be done with
caution however, because it can produce
cross-grain scratching that will require fur-
ther sanding to remove.
Change abrasive sheets as soon as the
grit becomes dull. You will recognize this
when the sander seems to slide across the
work without any “bite.”
Never apply excessive force while sand-
ing. Your sander will last longer if you let
“it” do the work. Using a slight pressure
barely greater than the weight of the
machine is ideal because you can still
maintain control while obtaining a fine fin-
ish.
