SECTION 1: SAFETY
For Your Own Safety Read Instruction Manual Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
Safety Instructions For Power Tools
1.KEEP GUARDS IN PLACE and in working order.
2.REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning on.
3.KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
4.DO NOT USE IN DANGEROUS ENVI- RONMENT. Do not use power tools in damp or wet locations, or where any flam- mable or noxious fumes may exist. Keep work area well lighted.
5.KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept a safe distance from work area.
6.MAKE WORKSHOP CHILD PROOF with padlocks, master switches, or by removing starter keys.

8.USE RIGHT TOOL. Do not force tool or attachment to do a job for which it was not designed.
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.
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.
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 is safer than using your hand and frees both hands to operate tool.
13.DO NOT
14.MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubri- cating and changing accessories.
15.USE RECOMMENDED ACCESSORIES.
Consult the owner???s manual for recom- mended accessories. The use of improper accessories may cause risk of injury.
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.
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, bind- ing 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 UNAT- TENDED. 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 OPER- ATE 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 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.
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.

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 opera- tion. Abrasive accessories have the abil- ity 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 BUFF- ING 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.
To operate this or any power tool safely and efficiently, it is essential to become as famil- iar 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.
No list of safety guidelines can be com- plete. 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.
SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
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 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.
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

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.
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 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.
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

NOTICE
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.
Test Run
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
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 nois- es. Strange or unnatural noises should be inves- tigated 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.
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.

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 5???8" hex nuts at the end of each shaft. Facing the machine, the
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.
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.

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.
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.
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

Buffing Wheel
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:
Laminated Sisal
Designed for rough cut- ting, sisal works well with various steels, copper, aluminum and brass to remove scratches and prepare the piece for polishing.
Loose Muslin
Soft
Spiral Sewn
Consist of layers of 100% unbleached cot- ton sheeting that are spiral sewn 1???8" apart. Works well for initial polish on brass, stain- less steel, aluminum, bronze and cast iron.
Airway Soft
Made of 100% cotton sheets and held togeth- er with a steel retainer. Pleats in the material help hold compound. These wheels are great for polishing soft metals and plastics.
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.
Check with your current Grizzly catalog for avail- ability on any of these wheel types.
Buffing Compound
Selection
Most colors of abrasives have similar applica- tions, but always check with the manufacturer of your particular compound. Grizzly offers the fol- lowing 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
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
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 com- pound that would normally be wasted on the floor.
???Only use the area
