General Safety Rules
WARNING! Read and understand all instructions.Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
•Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
•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.
•Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.
•Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
•Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified
electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system.
•Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
•Don’t expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
•Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
•When operating a power tool outside, use an outdoor extension cord marked
heavier gage. The smaller the gage number, the heavier the cord.
Minimum Gage for Cord Sets
Total Length of Cord in Feet
•Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury,
•Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be caught in moving parts.
•Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or
plugging in tools that have the switch on invites accidents.
•Remove adjusting keys or switches before turning the tool on.
A wrench or key that is left attached to a rotating part of the tool may result in personal injury.
•Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
•Use safety equipment. Always wear eye protection. Dust mask,
TOOL USE AND CARE
•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.
•Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
•Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
•Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventative safety measures reduce the risk of starting the tool accidentally.
•Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
•Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.
•Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
•Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
•Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
•When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual.
Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.
Additional Safety Rules
•Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
•Keep handles dry, clean, free from oil and grease. It is recommended to use rubber gloves. This will enable better control
•DO NOT TOUCH ANY METAL PARTS OF THE TOOL when drilling or driving into walls, floors or wherever live electrical wires may be encountered. Hold the tool only by insulated grasping surfaces to prevent electric shock if you drill or drive into a live wire.
•The label on your tool may include the following symbols.
no load speed
revolutions per minute
safety alert symbol
Additional Safety Instructions for Sanders
• ALWAYS WEAR EYE PROTECTION.
• Clean your tool out periodically.
CAUTION: Wear appropriate personal hearing protection during
use. Under some conditions and duration of use, noise from this
product may contribute to hearing loss.
WARNING: 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:
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from
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, such as those dust masks that are specially designed to filter out microscopic particles.
•Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

Single Speed Switch (ET1460 ONLY)
These tools are equipped with a single speed
The tool can be locked on for continuous use by squeezing the trigger switch fully and depressing the lock button shown in Figure 2. Hold the lock button in as you gently release the trigger switch. The tool will continue to run. To turn the tool off from a locked on position, squeeze and release the trigger switch once. Do not unplug the tool with the switch in the locked on condition. Make sure the tool is not locked on when plugging in. A locked on tool will start immediately when plugged in.
SPEED CONTROL WHEEL
Variable Speed Switch
(ET1480 and ET1490 ONLY)
These tools are equipped with a variable speed switch that permits speed control from (zero to 1750 RPM - ET1480) (zero to 1000/3000 RPM - ET1490). To turn the tool on, squeeze the trigger switch shown in Figure 2 until the tool starts to run. The farther you depress the trigger, the faster it will operate. Releasing the trigger turns the tool off.
Use lower speeds for applying liquid waxes and polishes and higher speeds for removing dried liquid. Use the highest speed (fully depress trigger) for buffing the car to a final lustre.
The tool can be locked on for continuous use by squeezing the trigger switch fully and depressing the lock button shown in Figure 2. Hold the lock button in as you gently release the trigger switch. The tool will continue to run. To turn the tool off from a locked on position, squeeze and release the trigger switch once. Do not unplug the tool with the switch in the locked on condition. Make sure the tool is not locked on when plugging in. A locked on tool will start immediately
when plugged in.
NOTE: The trigger can only be locked on with the tool running at the maximum RPM.
Speed Control Wheel (ET1490 ONLY)
The maximum speed of your tool can be changed by rotating the speed control wheel to the desired setting. The wheel incorporates detents to prevent inadvertent wheel movement and to facilitate speed selection. For added versatility, the switch may be locked in its full on position and tool speed changed by means of the speed control wheel alone (see Figure 3).
The electronic speed control not only lets you select the speed to suit the job, but also helps to maintain that speed as you load the tool by pressing down.
The speed control wheel can be set for any speed between 1000 and 3000 RPM and the variable speed switch will then control tool speed from zero to the wheel setting. For example: A control wheel setting of 2200 RPM will allow the variable speed switch to operate the tool between zero and 2200 RPM, depending on how far the trigger is depressed. A wheel setting of 1000 RPM would allow the switch to operate the tool from zero RPM to 1000 RPM.
The electronic speed control feature comes into play whenever the trigger switch is fully depressed and the tool is running at the selected speed determined by the setting of the control wheel. As you load the tool by pushing it down on the work surface, (with the trigger fully depressed) the electronic circuit inside the tool will compensate for the loading and maintain the selected speed. If the speed selected by the control wheel is 2200 RPM, as in the example above, the tool will maintain 2200 RPM, as it is loaded.
It is important to remember two things about electronic speed control:
1.The electronic speed control operates only when the trigger switch is fully depressed.
2.The effect of electronic speed control is much easier to observe at
lower speed settings (2600 RPM and below), than at high speeds.
As the tool approaches 3000 RPM, the effect is considerably less
Keep in mind that, with a conventional polisher running at a typical no
load speed of 2400 RPM, the tool slows down to about 2000 RPM
under a polishing load. Your ET1490 will continue to run at 2400 RPM
(or any speed you select with the control wheel) as a load is applied.
Since it doesn’t slow down, the speed may be greater than you’re
used to so some extra caution should be observed until you get the
“feel” of your polisher. If you feel the speed is too great, you can, of
course slow the tool down with either the trigger switch or the control
Spindle Lock Button
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
(See Figure 1) In order to prevent the spindle of the tool from rotating
while installing or removing accessories, a spindle lock button has
been provided in the gear head of the machine. To lock the spindle,
depress and hold the lock button. NEVER DEPRESS THE SPINDLE
LOCK BUTTON WITH THE TOOL RUNNING OR COASTING.
Attaching and Removing Polishing Pads
(FIGURES 4 & 5)
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
To attach pad, push the hub of the clamp washer through the hole in
the center of the polishing pad as far as it will go. Engage the
hexagonal hole in the backing pad. Holding the three pieces firmly
together, place the assembly on the tool spindle. Hold the spindle
lock button while turning the pads clockwise to thread them
completely on the spindle.
To remove the pads, turn them by hand in the opposite direction from
normal rotation to allow lock button to engage spindle, then unscrew
pads in normal direction for right hand thread.
NOTE: If you are using a polishing bonnet, rather than a pad, put clamp washer on first, pull bonnet completely over backing pad and pull draw strings tight Tie bow knot and push knot and all loose string completely under the inside, cloth edge of the polishing bonnet.
WARNING: TIED KNOT AND ALL STRINGS MUST BE TUCKED ENTIRELY UNDER THE CLOTH APRON. FAILURE TO DO SO MAY CAUSE SERIOUS INJURY.
These instructions and suggestions are intended to familiarize new operators in overall general operation of power polishing. You will develop your own techniques which will make the job easier and faster as you learn power polishing.
You should use utmost care when power polishing around or over sharp objects and contours of the car body. It is very important to use the correct pressure while polishing various sections of an automobile body. For example, light pressure should be applied when polishing over sharp edges of body panels, or over edges of the rain gutter along the top.
Since everyone does not use the same type of power polish, we
recommend you clean and polish a test section on a flat area of the car first. From this test section, you can judge the strength or cleaning action of your power polish.
Remember, all power polish is not the same. Different brands will react differently on various painted surfaces. Also, you are now using a power polisher with power polish. This is entirely different from any hand application which you may have done before. Wash the car before power polishing it. Washing will remove loose dirt, scum, road salt, etc. which could act as an abrasive and damage paint. Loose dirt, etc. will also clog the polishing pad and you will have to clean it more often.
Without turning the tool on, grasp the handles of the tool and pick it up. Keep the tool away from your body and turn the switch on. Make sure you have a firm grip on the handles and operate the tool freely without forced effort or unnecessary pressure. The side handle can be easily changed to either side of the tool for
NOTE: The high speed rubbing action of the polishing bonnet upon the surface of an automobile can build a static charge on the metal portions of this tool. This can result in a sensation of a very short mild electric shock when the metal area of the tool is touched, and will be more noticeable on days when the humidity is low. This is a harmless phenomenon but you are invited to bring the tool to a
Sanding Application (ET1490 ONLY)
ATTACHING AND REMOVING ABRASIVE DISCS (FIGURES 6, 7, AND 8)
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
To attach the sanding disc, push the hub of the clamp washer through the center of the sanding and phenolic discs, as far as it will go, and also through the backing pad. Engage the clamp washer threads on the tool spindle and thread assembly clockwise, completely down on the spindle. Hold the spindle from rotating by engaging the spindle
To remove the abrasive disc, use a cloth or glove to protect your hand. Turn the disc assembly counterclockwise (Figure 8). Hold the spindle from rotating by engaging the spindle lock button.
Sanding (ET1490 ONLY)
(See Figure 9) When using an abrasive disc, hold the tool so that an angle of 10˚ to 15˚ exists between the disc and the work. If only the outer edge of the sanding disc is used, a rough cut will result. If the sanding disc is pressed flat against the work, the sanding action will be irregular and bumpy, and the tool will be difficult to control.
Blowing dust, polishing bonnet lint, and grit out of the motor housing using compressed air is a necessary regular maintenance procedure. Dust and grit containing metal particles often accumulate on interior surfaces could create an electrical shock hazard if not frequently cleaned out.
CAUTION: Never use solvents or other harsh chemicals for cleaning the
