Safety Instructions For Power Tools
14. MAINTAIN TOOLS WITH CARE.
Keep tools sharp and clean for
best and safest performance.
Follow instructions for lubricating
and changing accessories.
9. USE PROPER EXTENSION CORD
for the tool. Make sure your exten-
sion cord is in good condition.
Conductor size should be in accor-
dance with the chart below. The
amperage rating should be listed on
the motor or tool nameplate. An
undersized cord will cause a drop in
line voltage resulting in loss of power
and overheating. Your extension
cord must also contain a ground wire
and plug pin. Always repair or
replace extension cords if they
become damaged.
15. DISCONNECT TOOLS before ser-
vicing and changing accessories,
such as blades, bits, cutters, and
the like.
16. REDUCE THE RISK OF UNIN-
TENTIONAL STARTING. Make
sure switch is in off position before
plugging in.
17. USE RECOMMENDED ACCES-
SORIES. Consult the owner’s
manual for recommended acces-
sories. The use of improper acces-
sories may cause risk of injury.

18. CHECK DAMAGED PARTS.
Before further use of the tool, a
guard or other part that is dam-
aged should be carefully checked
to determine that it will operate
properly and perform its intended
function. Check for alignment of
moving parts, binding of moving
parts, breakage of parts, mount-
ing, and any other conditions that
may affect its operation. A guard or
other part that is damaged should
be properly repaired or replaced.

10. WEAR PROPER APPAREL. Do not
wear loose clothing, gloves, neck-
ties, rings, bracelets, or other jewel-
ry which may get caught in moving
parts. Non-slip footwear is recom-
mended. Wear protective hair cover-
ing to contain long hair.
11. ALWAYS USE SAFETY GLASSES.
Also use face or dust mask if cutting
operation is dusty. Everyday eye-
glasses only have impact resistant
lenses, they are NOT safety glass-
es.
No list of safety guidelines can be
complete. Every shop environment
is different. Always consider safety
first, as it applies to your individual
working conditions. Use this and
other machinery with caution and
respect. Failure to do so could result
in serious personal injury, damage
to equipment or poor work results.
12. SECURE WORK. Use clamps or a
vise to hold work when practical. It’s
safer than using your hand and frees
both hands to operate tool.
13. DON’T OVERREACH. Keep proper
footing and balance at all times.

OPERATION INSTRUCTIONS
Attaching Abrasives
Getting Started
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.
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.
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.
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.
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.”
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.
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.
ALUMINUM OXIDE and SILICON CAR-
BIDE abrasives are an excellent choice
because they last longer and are sharper
than natural abrasives.

MAINTENANCE
General
Repair and Service
Regular periodic maintenance on your
Model G9910 Hook Loop
All quality tools will eventually wear from
normal use. Since sander is encased in a
double insulated plastic cover, leave repair
and service issues to a qualified service
technician. This includes brush replace-
ment, lubrication or any other internal
operation.
&
Sander/Polisher will ensure its optimum
performance. Make a habit of inspecting
your sander each time you use it. Check
for the following conditions and repair or
replace when necessary:
1. Loose fasteners.
2. Worn switch.
3. Worn or damaged cords and
plugs.
4. Worn or damaged rubber backing
pad or abrasive sheet.
5. Any other condition that could
hamper the safe operation of this
machine.
You can replace the rubber backing pad
that holds the abrasive sheets if it
becomes worn. Simply remove the four
screws that hold backing plate to the body
of the sander and replace with a new rub-
ber backing piece, installing the reverse of
removal. Always make sure you re-tighten
the rubber backing screws sufficiently
enough, so you don’t have problems when
you resume operations.
Keeping Tool Clean
Your G9910 Rotary Sander will give you
years of trouble free service if you keep it
clean and free of built-up dust or grime.
Ensure that no air passages get blocked. If
they do, blow them out with compressed
air. WARNING: Wear safety glasses when
cleaning tool with compressed air.
Disassembly and improper reassem-
bly of this device can result in elec-
trical shock danger. Always have this
device serviced by a qualified electri-
cal repair technician. Serious injury
will result.
Plastic parts can easily be cleaned with a
damp cloth, but never use water to clean
any electrical parts. Solvents should also
be avoided on plastic because of the pos-
siblity of damage.
If possible use a scraper to remove glue or
sap from your work; these elements may
hinder the effectiveness of the abrasive
sheets and cause unnecessary build-up of
grime on the sander.
