Safety Instructions For Power Tools

16. REDUCE THE RISK OF UNINTENTION­AL STARTING. On machines with magnet-

ic contact starting switches there is a risk of
starting if the machine is bumped or jarred.
Always disconnect from power source
before adjusting or servicing. Make sure
switch is in OFF position before reconnecting.

17. MANY WOODWORKING TOOLS CAN
“KICKBACK” THE WORKPIECE toward the

operator if not handled properly. Know what
conditions can create “kickback” and know
how to avoid them. Read the manual accom­panying the machine thoroughly.

18. CHECK DAMAGED PARTS. Before fur-

ther 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.

19. NEVER LEAVE TOOL RUNNING UNAT­TENDED. TURN POWER OFF. Do not

leave tool until it comes to a complete stop.

20. NEVER OPERATE A MACHINE WHEN
TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Full mental alert-

ness is required at all times when running a
machine.

21. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPER­ATE THE MACHINE. Make sure any

instructions you give in regards to machine
operation are approved, correct, safe, and
clearly understood.

22. IF AT ANY TIME YOU ARE EXPERIENC­ING DIFFICULTIES performing the intend-

ed operation, stop using the machine! Then
contact our service department or ask a
qualified expert how the operation should
be performed.

Additional Safety Instructions For Buffers

1. ALWAYS WEAR EYE PROTECTION!

2. WEAR AN APPROVED DUST MASK
OR RESPIRATOR. Buffing operations

produce dust.

3. MAKE SURE BUFFER IS SECURED
FIRMLY TO A BENCH OR STAND
BEFORE USE. Any “wobbles” must be

corrected by shimming or blocking before
operation.

4. DO NOT USE GRINDING WHEELS ON
THIS MACHINE. It is strictly designed for

buffing and drum sanding only.

5. DO NOT stand directly in front of buffing

or sanding accessories when turning
machine on.

6. PERFORM machine inspections and

maintenance service promptly when
called for.

7. DO NOT allow your hands to come into

contact with buffing wheels during opera­tion. Abrasive accessories have the abil­ity to remove a lot of material, including
skin, very quickly.

8. ANY PROBLEM concerned with any

moving parts or accessories must be
investigated and corrected with the
power disconnected, and after everything
has come to a complete stop.

9. NEVER leave the machine running unat-

tended.

10. NEVER BUFF BY PLACING THE
WORKPIECE ON TOP OF THE BUFF­ING WHEEL. The wheel may kick the

workpiece toward the operator. Always
buff on the downward part of the buffing
wheel.

11. HOLD THE WORKPIECE FIRMLY
WHILE BUFFING.

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 follow guidelines could
result in serious personal injury, damage to
equipment or poor work results.

To operate this or any power tool safely and
efficiently, it is essential to become as famil­iar with it as possible. The time you invest
before you begin to use your Model H4380
will be time well spent. DO NOT operate this
machine until you are completely familiar
with the contents of this manual or serious
personal injury may occur.

110V Operation

SECTION 2: CIRCUIT REQUIREMENTS

If you find it necessary to use an extension cord
with the Model H4380, make sure the cord is
rated Hard Service (grade S) or better. Refer to
the chart in the standard safety instructions to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin. Always repair or replace
extension cords when they become worn or dam­aged.

Extension Cords

Grounding

This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no cir­cumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.

In the event of an electrical short, grounding
reduces the risk of electric shock by providing
electric current a path of least resistance. This
tool is equipped with a power cord having an

equipment-grounding conductor. See Figure 1B.

The outlet must be properly installed and ground­ed in accordance with all local codes and ordi­nances.

The Model H4380 is wired for 110V. The

1

⁄2 H.P.
motor will safely draw 3.5 amps at 110V. If you
operate this machine on any circuit that is already
close to its capacity, it might blow a fuse or trip a
circuit breaker. However, if an unusual load does
not exist and a power failure still occurs, contact a
qualified electrician or our service department.

A 10 amp circuit should be used with this buffer.
Always check to see if your current wires are
capable of handling a 10 amp load. If you are
unsure, consult the advice of a qualified electri­cian.

Unpacking

Piece Inventory

NOTICE

A full parts list and breakdown can be found
toward the end of this manual. For easier
assembly, or to identify specific parts,
please refer to the detailed illustrations at
the end of the manual.

After all the parts have been removed from the
carton, you should have:

• Buffing Unit

• Wheel Flanges (4)

• Arbor Nuts (2)

Mounting

The Model H4380 weighs approximately 17 lbs.
Make sure the workbench on which you plan to
mount the buffer is sturdy enough to hold the
weight of the machine. The workbench should
have a level surface and be heavy, or attached to
the floor, so it will not move during operation. To
mount the buffer:

1. Pick a spot on the workbench that will allow

enough room to move the size of an antici­pated workpiece around the buffer. The oper­ator (and possibly bystanders) should have
enough room to stand out of the way in an
emergency.

2. Mount the buffer to the workbench with bolts

that are long enough to exceed the thickness
of your workbench and the buffer base.
Secure these bolts with a flat washers, a lock

washer and a hex nut. Because sizes vary for

each individual situation, the hardware in this
step is not included with the Model H4380.

3. Mount the buffer in an area with proper light-

ing and near electrical outlets. Lighting
should be bright enough to eliminate shadow
and prevent eye strain. Electrical circuits
should be dedicated or large enough to han­dle amperage requirements. Keep power or
extension cords clear of high-traffic areas.
Observe local electrical codes for proper
installation of new lighting, outlets, or circuits.

The Model H4380 is shipped from the manufac­turer in a carefully packed carton. If you discover
the machine is damaged after you have signed
for delivery, immediately call Customer Service
for advice.

When you are completely satisfied with the con­dition of your shipment, you should inventory its
parts.

Some metal parts may
have sharp edges on
them after they are
formed. Please examine
the edges of all metal
parts before handling
them. Failure to do so
could result in injury.

Make your shop “child safe.”
Ensure that your workplace
is inaccessible to children
by closing and locking all
entrances when you are
away. Never allow visitors in
your shop when assembling,
adjusting, or operating
equipment.

SECTION 6: OPERATIONS

Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.

Wear safety glasses dur­ing the entire operation
process. Failure to com­ply may result in serious
personal injury.

Using this machine pro­duces sawdust which may
cause allergic reactions
and respiratory problems.
Use an approved dust
mask to protect yourself
from these hazards!

NOTICE

The following section was designed to give
instructions on the basic operations of this
buffer. However, it is in no way comprehen­sive of every buffer application. There are
many different buffing wheels, compounds
and attachments available for buffers. WE
STRONGLY RECOMMEND that you read
books, trade magazines, or get formal train­ing to maximize the potential of your
machine.

Once mounting is complete and adjustments are
done to your satisfaction, you are ready to test
the machine. Before testing, remove the flanges
and shaft nuts from the arbor. Facing the
machine, the left-hand nut has left-handed
threads (remove by turning clockwise) and the
right-hand nut has right-handed threads (remove
by turning counterclockwise).

Plug in the power and turn the buffer ON. Make

sure that your hand is poised near the switch in
case there is a problem. The buffer should run
smoothly with little or no vibration or rubbing nois­es. Strange or unnatural noises should be inves­tigated and corrected before operating the
machine further.

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

Test Run

General

The Model H4380 8" Buffer is strictly designed for
buffing operations. IT IS NOT A GRINDER. The
absence of grinding wheel guards prohibit the use
of this machine as a grinder.

This buffer has a left and right shaft to provide the
option of mounting two different buffing wheels,
depending on your application. The convenience
of having two shafts allows you to mount different
textured buffing wheels onto each shaft.

Disconnect power to the
machine when perform­ing any maintenance,
assembly or adjust­ments. Failure to do this
may result in serious per­sonal injury.

Buffing & Polishing

For buffing and polishing, Grizzly offers a broad
line of buffing wheels and polishing compounds.
Please refer to our current catalog for more infor­mation on these. To buff or polish with the buffer:

1. Make sure the power cord is unplugged and

remove the

5

⁄8" hex nuts at the end of each
shaft. Facing the machine, the left-hand shaft
has left-handed threads. The right-hand shaft
has right-handed threads.

2. Sandwich a buffing wheel between the two

wheel flanges provided and slide the assem­bly onto the shaft. Use only the wheel flanges
supplied with this machine. The buffing

assembly should look similar to Figure 2.

Figure 2. Buffing wheels mounted.

Disconnect power to the
machine when removing
the wheels. Failure to do
this may result in serious
personal injury.

DO NOT buff on the top of the wheel or the
workpiece may be thrown back at you.
Refer to Figure 3 before using your buffer.

5. With both hands, firmly grasp the item to be

polished. Lightly and evenly move the work­piece back and forth on the edge of the buff­ing wheel in the grayed in area shown in

Figure 3. Be careful when polishing plated

metals; there is a chance that the thin plated
material may be damaged. A light pressure is
all that is needed for quality work.

3. Tighten the hex nut while holding the shaft

with your other hand. The direction of the
threads and motor rotation ensure that the
nuts on both sides will not self loosen.

4. Plug the buffer into the power source. Select

the appropriate stick of polishing compound

for your application, turn ON the buffer and

apply the compound to the rotating face of
the wheel. Always wear safety glasses
because particles of polishing compound or
buffing wheel may fly off.

Wheel Removal

To remove the buffing wheels, ensure that the

switch is turned OFF and the power cord is dis-

connected! Hold the shaft with one hand while
loosening the nut with a wrench. Remember, the
left-hand nut and shaft have left-handed threads.

Buffing Wheel

Selection

Buffing Compound

Selection

Buffing wheels are available for most types of
metals and for different stages in the buffing
process. The following pictures and descriptions
describe some of the more common wheel types:

Loose Muslin

Soft feather-edged
muslin stitched together
near the center leaves
the outer edge to pro­vide a wide angle, fine
polishing surface.
Perfect for polishing
stainless steel, chrome,
gold or silver.

Airway Soft

Made of 100% cotton
sheets and held togeth­er with a steel retainer.
Pleats in the material
help hold compound.
These wheels are great
for polishing soft metals
and plastics.

Spiral Sewn

Consist of layers of
100% unbleached cot­ton sheeting that are
spiral sewn

1

⁄8" apart.
Works well for initial
polish on brass, stain­less steel, aluminum,
bronze and cast iron.

Airway Hard

Made of 100% cotton
sheets that are treated
to stiffen the material.
Pleats in the material
help hold compound.
These are great for
rough cutting plastics
and initial polishing a
wide variety of metals.

Laminated Sisal

Designed for rough cut­ting, sisal works well
with various steels,
copper, aluminum and
brass to remove
scratches and prepare
the piece for polishing.

Check with your current Grizzly catalog for avail­ability on any of these wheel types.

Most colors of abrasives have similar applica­tions, but always check with the manufacturer of
your particular compound. Grizzly offers the fol­lowing compounds:

Red Rouge — Made for fine polishing on brass

and gold. Provides an excellent shine when used
with the loose muslin buffing wheel.

Green (Extra Fine) — Great for extra-fine polish-

ing on most metals to bring out that mirror finish.
Works best with loose muslin and spiral sewn
buffing wheels.

White — Great for ivory, plastic and resins when

used successively with the soft spiral sewn and
soft airway buffing wheels.

Black — Designed to be used with sisal and air-

way hard buffing wheels, this compound is perfect
for the initial rough cut on stainless steel and iron.

Tripoli — A true middle-of-the-road abrasive,

Tripoli provides an excellent medium cut for
brass, aluminum and zinc alloy.

Green (Fine) — Slightly more abrasive than the

extra fine green, this green compound is great for
a medium to fine polish with most softer metals.

Buffing Tips

Here are some quick tips for getting the most out
of your buffer:

• Thoroughly clean all parts that you are plan-

ning to buff. Any kind of dirt, oil, rust, paint or
other film must be removed either chemically
or sprayed off with water. Make sure to dry off
parts with a rag after cleaning.

• Apply buffing compounds in small amounts at

a time. While the machine is running, press
the compound on the wheel for a couple of
seconds. Avoid using too much compound.

• Put your workpiece under the wheel when

you are loading the compound on the buffing
wheel. This way, you will catch any com­pound that would normally be wasted on the
floor.

• Only use the area grayed-out in Figure 4 to

do the actual buffing. Contacting the work­piece on areas outside of the grayed out area
may flip the workpiece out of your hands.

• Hold the workpiece tightly at all times while

buffing. One hand near the contact point will
give you better control.

• Keep buffing wheels raked out before each
use and when buildup gets heavy during use.
“Raking” means to clean the buffing wheels
with a wheel rake to remove buildup com­pounds and metal particles. An old rough-cut
saw blade or a large hacksaw blade will also
work as an alternative to a wheel rake.
ALWAYS use light pressure when raking
wheels!

• Do not mix two different compounds on the
same wheel. For best results, use a separate
wheel for each compound.

• Use an upward stroke with heavy to moder­ate pressure for cutting. Use a downward
stroke with light to pressure for polishing. See

Figure 5.

Downward

to Polish

Upward

to Cut

Figure 5. Cutting and Polishing strokes.

•Wear safety equipment when buffing. If the
buffer forces the workpiece out of your hand,
be prepared for it to come flying at you! Wear
safety glasses and a heavy leather apron.
Also, wear a dust mask to protect your lungs
from microscopic particulate that will be flying
off the wheel.

Remember, there is no substitute for experience.
Learning how to hold the workpiece, how much
pressure to apply, how to move the workpiece
against the wheel and how much compound to
use will require some trial-and-error.
