2. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and There is an increased risk of electric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor Use of a cord suitable for outdoor use reduces the risk of electric shock.

1) PERSONAL SAFETY

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal
2. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal
3. Avoid accidental Ensure the switch is in the off-position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly Use of these devices can reduce dust-related hazards.

2)POWER TOOL USE AND CARE

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be
3. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power Power tools are dangerous in the hands of untrained users.
5. Maintain power Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

BUFFING BASICS

Warning

**Only work from the “Work Zone” at the front lower portion of

the Wheel (Fig 7). Subjecting a workpiece to a point above the centerline of the Arbor Shaft (Fig 8) can quickly tear the item from the operator’s hands and propel the object at over 80 MPH with great force.**

Warning

Always position workpiece edges so that the wheel is rotating “off the edge” (Fig 9). NEVER feed an edge “into” the wheel (Fig 10). Feeding an edge into a rotating wheel is extremely dangerous and will quickly and
violently kick the object back at the operator causing injury and damage. ****

DO NOT OVERLOAD!

The Buff Motor is designed to operate with minimal pressure against Buff Wheel and the best buffing results will always be accomplished by letting the rotating wheel do the work.
Attempts to quickly buff objects with excessive pressure will generate excessive heat which can damage the work piece, use excessive compound and rapidly wear buff wheels.
A good rule of thumb is to only apply the same amount of pressure to a rotating buff wheel as would be required to shut a drawer. If any deflection of the wheel is noticed, the pressure is too great.

NOT

When buffing plated objects, always use caution not to buff through the plating.

SELECTING BUFF WHEELS AND COMPOUND

Compounds are available in a variety of Grits to accommodate different metals and materials. In addition, Buff Wheels are offered in an array of textures ranging from soft to aggressive. Gener- ally, a harder material will require pairing a stiffer, more aggressive Buff Wheel with a courser grit

Compound. Also, as the buffing of a part continues, there is a progression of successively softer Buff Wheels and less aggressive Compound formulations.

The following chart can be used as a general guide to choosing the right Compound and Buff Wheel for the job:

*Use Caution to avoid buffing through plating.

**Avoid excessive heat build up which will destroy some plastics.
Always use a dedicated Buff Wheel for a specific compound. Example: if using Emery on a Sisal Wheel, use that Wheel exclusively with Emery Compound. Never contaminate a Buff Wheel by attempting to use another type of Compound. This can cause damage to the surface of a workpiece and ruin the Buff Wheel.

APPLYING COMPOUND

• Remove the Compound Bar from the package and holding it firmly, gently apply Compound to the “Work Zone” area of the rotating wheel (FIG 11). Apply sparingly, one or two seconds against the wheel every few minutes is More is not better, and it is best to apply a small amount more frequently than too much at once.q

BUFFING OBJECTS

As with many skills, Buffing requires a learning curve to become proficient; however once learned, will prove to be highly satisfying.
To get started, refer to the included Buffing & Metal _Finishing Instructions & How to Guide _for an understanding of some be practices to use when buffing. Another great source of guidance is item #13304 – Eastwood Art of Buffing Instructional DVD (not included).
It is highly recommended to practice buffing on some old objects of low value and experiment with different metals Compounds and Buff Wheels. Generally, expect to spend some time and waste some product before taking on something of value.

• Before turning on the Motor, take a few moments and plan the work to be done. Take notice of all sharp edges, corners or protruding features that could snag the Be sure to plan on buffing those areas with the wheel rotating away.

• Begin in one area, let the compound work and move the object across the piece across the wheel Never stop and hold the object against wheel. Use very light pressure and move down 1/4″ after each pass until finished (FIG 12).

• On larger objects, divide the surface area into 1” x 2” areas and move from area to

• When done, clean the surface of the just buffed object of all compound residue and Eastwood #10194ZP, PRE Painting Prep is excellent for cleaning buffing residue as are acetone, mineral spirits or denatured alcohol. If some ar- eas require additional attention, repeat above buffing process and check again. Numerous “clean & check” periods may need to be done to achieve the desired results.

• Always clean the buffing residue on the object before progressing to the next finest Compound/Wheel combination or contamination of the softer wheel will

• When stepping to the next finest Compound/Wheel combination, unplug the Buff Motor and change to the next

CLEANING BUFF WHEELS

After use, all Buff Wheels will build up an accumulation of compound and metal particles. When this occurs, it reduces the overall effectiveness and must be removed.
Use an Eastwood #13120 Buff Rake. To do so:

• Gripping it firmly by the handles, lightly press it into the rotating Wheel in “The Work Zone” of the Wheel in 10 second increments until the bulk of the material is removed (FIG 16).
• The Buff Rake will also true up an out of round wheel. This is done by first cleaning the wheel then holding the Rake at the edge of the Wheel and allowing just

the high spots to contact the Rake. As the “High Spot” fibers are removed, the Wheel will return to proper roundness.

STORING BUFF MOTOR

• Unplug from power
• Wrap cord securely around Buff
• Store in a clean, dry, dampness free area preferably covered with plastic

MAINTENANCE

The following maintenance should be performed before each use:

• Check tightness of all Motor and Wheel mounting
• Check Motor controls
• Inspect Buff Wheel for tears, damage or premature
