G9907 Triangular Sander
OPERATION INSTRUCTIONS
Getting Started
After making sure the power source
matches the specifications on the sander
label, plug in sander. Push the black
switch (on top of the tool’s handle) forward
to turn it on, and pull the switch back 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 correct-
ed before operating the machine further.
If you cannot easily locate the source of
an unusual noise or vibration, contact our
service department for help.
Selecting Abrasives
The best results from your G9907
Triangular Sander will be accomplished
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 G9907 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 or corner 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.
