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 “W-A” or “W.” These cords are rated for

outdoor use and reduce the risk of electric shock. When using an

extension cord, be sure to use one heavy enough to carry the

current your product will draw. An undersized cord will cause a drop

in line voltage resulting in loss of power and overheating. The

following table shows the correct size to use depending on cord

length and nameplate ampere rating. If in doubt, use the next

heavier gage. The smaller the gage number, the heavier the cord.

PERSONAL SAFETY

•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

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

WORK AREA

•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.

ELECTRICAL SAFETY

• 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

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,

non-skid safety shoes, hard hat, or hearing protection must be used

for appropriate conditions.

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.

SERVICE

•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.

when plugged in.

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:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry

products, and

• arsenic and chromium from chemically-treated lumber (CCA).

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.

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

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

dramatic.

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

wheel.

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

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.

Polishing

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

lock button.

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.

Cleaning

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 non-metallic parts of the tool. Use clean, dry rag only.

Lubrication

Snap-on tools are properly lubricated at the factory and are ready

for use. Tools should be relubricated regularly every sixty days to six

months, depending on usage. (Tools used constantly on production

or heavy-duty jobs and tools exposed to heat may require more

frequent lubrication.) This lubrication should only be attempted by

trained power tool repairpersons such as those at Snap-on service

centers or other authorized service locations.

Motor Brushes

Be sure tool is unplugged before inspecting brushes. Carbon brushes

English

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 left-handed or right-

handed operation.

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 Snap-on service center where it can be

checked to assure that no electrical malfunction is present.
