Safety Instructions For Power Tools
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi-
tion. 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 exten-
sion cords if they become damaged.
16. REDUCE THE RISK OF UNINTENTION-
AL 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 accom-
panying the machine thoroughly.

TENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.
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.
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.
12. SECURE WORK. Use clamps or a vise to hold
work when practical. It is safer than using your
hand and frees both hands to operate tool.
21. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPER-
ATE THE MACHINE. Make sure any
instructions you give in regards to machine
operation are approved, correct, safe, and
clearly understood.
13. DO NOT OVER-REACH. Keep proper
footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for lubri-
cating and changing accessories.
22. IF AT ANY TIME YOU ARE EXPERIENC-
ING 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.
15. USE RECOMMENDED ACCESSORIES.

may occur.
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 electri-
cian.
Extension Cords
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 dam-
aged.
Figure 1A. Do not remove grounding pin.
Grounding
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 ground-
ed in accordance with all local codes and ordi-
nances.

Unpacking
Mounting
The Model H4380 is shipped from the manufac-
turer in a carefully packed carton. If you discover
the machine is damaged after you have signed
for delivery, immediately call Customer Service
for advice.
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:
When you are completely satisfied with the con-
dition of your shipment, you should inventory its
parts.
1. Pick a spot on the workbench that will allow
enough room to move the size of an antici-
pated workpiece around the buffer. The oper-
ator (and possibly bystanders) should have
enough room to stand out of the way in an
emergency.
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.
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 han-
dle 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.
Piece Inventory
After all the parts have been removed from the
carton, you should have:
• Buffing Unit
• Wheel Flanges (4)
• Arbor Nuts (2)
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.
NOTICE
A full parts list and breakdown can be found
toward the end of this manual. For easier
assembly, or to identify specific parts,

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.
NOTICE
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.
The following section was designed to give
instructions on the basic operations of this
buffer. However, it is in no way comprehen-
sive 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 train-
ing to maximize the potential of your
machine.

5. With both hands, firmly grasp the item to be
polished. Lightly and evenly move the work-
piece back and forth on the edge of the buff-
ing 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.
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 infor-
mation on these. To buff or polish with the buffer:
1. Make sure the power cord is unplugged and

remove the ⁄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 assem-
bly onto the shaft. Use only the wheel flanges
supplied with this machine. The buffing
assembly should look similar to Figure 2.

Wheel Removal
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.
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.
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.
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.

•
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 com-
pounds 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!
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.
•
•
Do not mix two different compounds on the
same wheel. For best results, use a separate
wheel for each compound.
•
•
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.
Use an upward stroke with heavy to moder-
ate pressure for cutting. Use a downward
stroke with light to pressure for polishing. See
Figure 5.
Put your workpiece under the wheel when
you are loading the compound on the buffing
wheel. This way, you will catch any com-
pound that would normally be wasted on the
floor.
Downward
to Polish
•
Only use the area grayed-out in Figure 4 to
do the actual buffing. Contacting the work-
piece on areas outside of the grayed out area
may flip the workpiece out of your hands.

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.

Here
Figure 4. Illustrated from a side profile, shows
the only portion of the wheel that should be used
during buffing.
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.
•
Hold the workpiece tightly at all times while
buffing. One hand near the contact point will
give you better control.
