WARNING

Some dust created by power sanding, sawing, grind­ing, drilling, and other construction activities contains
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement, and
other masonry products.

• Arsenic and chromium from chemically
treated lumber.

Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to fil­ter out microscopic particles.

the job better and safer at the rate
for which it was designed.

8. USE RIGHT TOOL. DO NOT force
tool or attachment to do a job for
which it was not designed.

1. KEEP ALL SAFETY DEVICES IN
PLACE and in working order.

2. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of check-

ing to see that keys and adjusting
wrenches are removed from tool
before turning on.

3. KEEP WORK AREA CLEAN.

9. USE PROPER EXTENSION CORD

for the tool. Make sure your exten­sion cord is in good condition.
Conductor size should be in accor­dance 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.

Minimum Gauge for Extension Cords

10. WEAR PROPER APPAREL. DO
NOT wear loose clothing, gloves,
neckties, rings, bracelets, or other
jewelry which may get caught in
moving parts. Non-slip footwear is
recommended. Wear protective hair
covering to contain long hair.

11. ALWAYS USE SAFETY GLASSES.

Also use face or dust mask if cutting
operation is dusty. Everyday eye­glasses only have impact resistant
lenses, they are NOT safety glass­es.

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. DO NOT OVERREACH. Keep prop­er footing and balance at all times.

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.

15. DISCONNECT TOOLSbefore ser-

vicing and changing accessories,
such as blades, bits, cutters, and
the like.

16. REDUCE THE RISK OF UNIN­TENTIONAL STARTING. Make

sure switch is in off position before
plugging in.

17. USE RECOMMENDED ACCES­SORIES. Consult the owner’s

manual for recommended acces­sories. The use of improper acces­sories may cause risk of injury.

18. CHECK DAMAGED PARTS.

Before further use of the tool, a
guard or other part that is dam­aged 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, mount­ing, and any other conditions that
may affect its operation. A guard or
other part that is damaged should
be properly repaired or replaced.

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.

OPERATION INSTRUCTIONS

Starting Sander

Plug the cord into a 110V outlet. Move the
black switch (located at the front of the
sander) to the “–” position to turn the
sander ON, and move the switch to the
“O” position to turn the sander OFF. The
sander should run smoothly. Strange or
unnatural noises should be investigated
and corrected before operating further.

If you cannot easily locate the source of
an unusual noise or vibration, contact our
service department for help.

Selecting Abrasive Types

ALUMINUM OXIDE abrasives are an
excellent choice because they last longer
and are sharper than natural abrasives.

Selecting Grit Sizes

As a general rule, start with a coarse grit
size and move through finer grit sizes until
you achieve your desired results.

Use the list below to define paper grit
sizes:

• Extra Coarse..............................12-20

• Very Coarse ..............................24-36

• Coarse ......................................40-50

• Medium ....................................60-100

• Fine........................................120-180

• Very Fine ..............................220-280

• Extra Fine ..............................320-400

Attaching Abrasives

Abrasive sheets can be easily attached
with the hook-and-loop system on the pad
of your Model H3120 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 suc-

tion holes.

Using the Sander

Determine the appropriate grit size for
your project and sand the work evenly in
the same direction as the grain of the
wood. Always keep the sander moving so
the finish of your work stays consistent. If

you stay in one place too long, then the
sander may produce 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 fur­ther 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 sand­ing. 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 fin­ish.

MAINTENANCE

General

Regular periodic maintenance on your
Model H3120 Palm Sander 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 sanding pad.

5. Any other condition that could hamper

the safe operation of this machine.

Keeping Tool Clean

Your Model H3120 Palm 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.

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 pos­sibility 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 build­up of grime on the sander.

Repair and Service

All quality tools will eventually wear from
normal use. Since this sander is encased
in an insulated plastic cover, leave repair
and service issues to a qualified service
technician. This includes brush replace­ment, lubrication or any other internal
operation.

Disassembly and improper reassem­bly of this device can result in elec­trical shock danger. Always have this
device serviced by a qualified electri­cal repair technician. Serious injury
will result.
