GENERAL SAFETY INSTRUCTIONS

WARNING! Read all safety warnings and

all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future

reference. The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

e. When operating a power tool outdoors, use

an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

f. If operating a power tool in a damp location is unavoidable, use an earth

leakage circuit breaker. Use of an earth leakage circuit breaker reduces the risk of electric shock.

1) WORK AREA SAFETY

a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b. Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c. Keep children and bystanders away while

operating a power tool. Distractions can cause you to lose control.

2) ELECTRICAL SAFETY

a. Power tool plugs must match the outlet.

Never modify the plug in any way. Do not use any adapter plugs with ear thed

(grounded) power tools.

Unmodified plugs and matching outlets will reduce risk of electric shock.

b. Avoid body contact with ear thed or grounded surfaces such as pipes, radiators,

ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c. Do not expose power tools to rain or wet

conditions. Water entering a power tool will increase the risk of electric shock.

d. Do not abuse the cord. 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.

3) PERSONAL SAFETY

a. a) 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 injury.

b. b) Use personal protective equipment.

Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d. Remove any adjusting key or wrench

before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e. Do not overreach. Keep proper footing and

balance at all times. This enables better control of the power tool in unexpected situations.

f. Dress properly. 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.

g. If devices are provided for the connection of dust extraction and collection facilities,

ensure these are connected and properly used.

Use of dust collection can reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a. 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 designed.

b. 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 repaired.

c. 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 accidentally.

d. Store idle power tools out of the reach of c h i l d re n a n d d o n o t a l l ow p e r s o n s unfamiliar with the power tool or these

instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e. M a i n t a i n p o w e r t o o l s . C h e c k f o r misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation.

If damaged, have the power tool repaired

before use. Many accidents are caused by poorly maintained power tools.

f.

Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g. Use the power tool, accessories and tool b i t s e tc. , i n a cco rd a n ce w i t h t h e s e instructions, taking into account the working conditions and the work to be

per formed. Use of the power tool for operations different from those intended could result in a hazardous situation.

SAFETY WARNINGS COMMON FOR

SANDING OR POLISHING OPERATIONS

1. This power tool is intended to function as a sander or polisher. Read all safety warnings, instructions, illustrations and specifications provided with this power

tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

2. O p e rat i o n s s u c h a s g r i n d i n g, w i re b r u s h i n g , o r c u t t i n g - o f f a r e n o t recommended to be performed with this

power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.

3. Do not use accessories which are not specifically designed and recommended

by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

4. The rated speed of the accessory must be at least equal to the maximum

s p e e d m a r k e d o n t h e p o w e r t o o l .

Accessories running faster than their rated speed can break and fly apart.

5. The outside diameter and the thickness of your accessory must be within the

capacity rating of your power tool.

Incorrectly sized accessories cannot be adequately guarded or controlled.

6. The arbour size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the

power tool. Accessories with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.

7. Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped,

5

inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load

s p e e d fo r o n e m i n u t e. D a m a g e d accessories will normally break apart during this test time.

8. Wear personal protective equipment.

Depending on application, use face shield, safety goggles or safety glasses.

As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or

workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations . The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

9. Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective

equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.

10. Hold power tool by insulated gripping sur faces only, when per forming an operation where the cutting accessory may contact hidden wiring or its own

cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and shock the operator.

11. Position the cord clear of the spinning

accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.

12. Never lay the power tool down until the accessory has come to a complete stop.

The spinning accessory may grab the surface and pull the power tool out of your control.

13. Do not run the power tool while

carrying it at your side. Accidental

contact with the spinning accessory could snag your clothing, pulling the accessory into your body.

14. Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

15. Do not operate the power tool near

flammable materials. Sparks could ignite these materials.

16. Do not use accessories that require

liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or

torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.

2. Never place your hand near the rotating

accessory. Accessory may kickback over your hand.

3. Do not position your body in the area where power tool will move if kickback

occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.

4. Use special care when working corners, sharp edges etc. Avoid bouncing and

snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.

5. Do not attach a saw chain woodcarving

blade or toothed saw blade. Such blades create frequent kickback and loss of control.

FURTHER SAFETY INSTRUCTIONS FOR

ALL OPERATIONS

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.

For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

1. Maintain a firm grip on the power tool and position your body and arm to allow you

SAFETY WARNINGS SPECIFIC FOR

SANDING OPERATIONS

Do not use excessively oversized sanding d i s c p a p e r. F o l l o w m a n u f a c t u r e r s recommendations, when selecting sanding

paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

SAFETY WARNINGS SPECIFIC FOR POLISHING

OPERATIONS

Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely.

Tuck away or trim any loose attachment

strings. Loose and spinning attachment strings

can entangle your fingers or snag on the workpiece.

SPECIFIC SAFETY RULES

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

* lead from lead-based paints

* crystalline silica from bricks and 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, always wear NIOSH/OSHA approved, properly fitting face mask or respirator when using such tools

1. Use clamps or other practical way to secure and support the workpiece to a

stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

2. Keep hands away from rotating parts.

3. Wear eye and hearing protection. Always use safety glasses. Everyday eyeglasses are NOT safety glasses.

USE CERTIFIED SAFETY EQUIPMENT.

4. Use of this tool can generate and disburse dust or other airborne particles, including wood dust, crystalline silica dust and

asbestos dust. Direct particles away from face and body. Always operate tool in well ventilated area and provide for proper dust removal. Use dust collection system wherever possible. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with

7

dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.

MOTOR

Always check the nameplate to ensure the A.C. current supply is the correct voltage for your machine. This tool will operate on voltage within plus or minus 5 percent of that shown on the specification plate on the tool. Refer to the specification plate on your tool for proper voltage and current rating. Do not operate your tool on a current on which the voltage is not within correct limits. If an extension cord is used, make sure the conductor size is large enough to prevent excessive voltage drop which will cause loss of power and possible motor damage. If an extension cord is to be used outdoors, it must be marked

with the suffix WA or W following the cord type designation. For example – SJTW-A to indicate it is acceptable for outdoor use. Always choose the shortest possible cord.

FOREWORD

This Rotary Polisher (also known as a Circular

Polisher) is designed for fast compounding, polishing, buffing and sanding. The pad spins on one axis, so much work can be done quickly. In polishing applications, much heat can be built up in a small area, which could lead to paint damage.

Therefore, this tool is recommended for use by professionals only. Anyone new to rotary polishers should master the craft on scrap car panels, available at a local salvage yard.

OPERATION

TO START AND STOP THE MACHINE

CAUTION: Make sure switch is OFF and power circuit voltage is the same as that shown on the specification plate.

POLISHING OPERATION

WARNING: If the item to be polished is not attached to anything and is light enough to be moved by the spinning polishing pad, it should be securely clamped or anchored to prevent it being thrown or flung, resulting in possible

injury.

1. Hold the machine firmly by the main and side handles, making sure the polishing pad is clear of foreign objects.

2. Start the machine and lower it at an angle so that about half of the polishing pad contacts the work.

3. Move the machine in long continuous sweeping strokes. DO NOT HOLD POLISHER

IN ONE SPOT Doing so will overheat the surface and cause swirl marks. It is possible to damage and burn through the paint very quickly.

4. Always be sure motor has stopped before setting the machine down.

FAILURE TO START

Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line

THE CARBON BRUSHES

The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit.

NOTE: Checking and replacing the carbon brushes should be entrusted to a qualified service center.

T h e c a r b o n b r u s h e s f u r n i s h e d w i l l l a s t approximately 50 hours of running time or 10,000 on/off cycles. Replace both carbon brushes when either has less than 1/4" length of carbon remaining.

MAINTENANCE

Every 50 hours of operation blow compressed air through the motor while running at no load to clean out accumulated dust. (If operating in especially dusty conditions, perform this operation more often.) To inspect or replace brushes, first unplug the machine.

KEEP TOOL CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear safety glasses while using compressed air.

Caution: Always replace the brushes as a pair

TO REPLACE

simply remove the brush caps and withdraw the old brushes. Replace with new brushes (always replace as a pair) ensuring that they align properly and slide freely. Then replace the brush caps.

NOTE: To reinstall the same brushes, first make sure the brushes go back in the way they came out. Otherwise a break-in period will occur that will reduce motor performance and increase brush wear.

If the replacement of the power supply cord is necessary, this has to be done by the manufacturer or their agent in order to avoid a safety hazard.

WARNING: All repairs must be entrusted to an

authorized service center. Incorrectly performed repairs could lead to injury or death.
