NOTE emphasizes essential information.

English

SAFETY

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

1. Work Area (1) Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

(2) 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 of fumes.

(3) Keep bystanders children, and visitors away while operating a power tool.

Distractions can cause you to lose control.

2. Electrical Safety (1) 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.

(2) 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.

(3) Don’t expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

(4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from a

receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

(5) 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.

3. Personal Safety (1) 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.

(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your

hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair

can be caught in moving parts.

(3) 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.

English

(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that

is left attached to a rotating part of the tool may result in personal injury.

(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enables better control of the tool in unexpected situations.

(6) Use safety equipment. Always wear protective glasses. Dust mask, nonskid safety

shoes, hard hat, or ear plugs must be used for appropriate conditions.

4. Tool Use and Care (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) 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.

(3) 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.

(4) Disconnect the plug form the power source before making any adjustments,

changing accessories, or storing the tool. Such preventive safety measures reduce

the risk of starting the tool accidentally.

(5) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

(6) 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.

(7) 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.

(8) 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.

5. Service (1) Tool service must be performed only by qualified repair personnel. Service or

maintenance performed by unqualified personnel could result in a risk of injury.

(2) 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 Instruction may create a risk of electric shock or injury.

6. Never touch moving parts.

Never place your hands, fingers or other body parts near the tool’s moving parts.

7. Never operate without all guards in place.

Never operate this tool without all guards or safety features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.

8. Use right tool.

Don’t force small tool or attachment to do the job of a heavy-duty tool. Don’t use tool for purpose not intended —for example— don’t use circular saw for cutting tree limbs or logs.

9. Never use a power tool for applications other than those specified.

Never use a power tool for applications other than those specified in the Instruction Manual.

English

10. Handle tool correctly.

Operate the tool according to the instructions provided herein. Do not drop or throw the tool. Never allow the tool to be operated by children, individuals unfamiliar with its operation or unauthorized personnel.

DOUBLE INSULATION FOR SAFER OPERATION

To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. “Double insulation “ means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol “ ” or the words “Double insulation” appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments. To keep the double insulation system effective, follow these precautions: 䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this

power tool, and only genuine HITACHI replacement parts should be installed.

䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water,

and dry thoroughly. Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.

䡬 Polishing or shining painted metal surfaces, such as those of automobiles, trains,

elevators, refrigerators, sewing machines, washing machines, metal appliances, etc.

䡬 Polishing varnished surfaces of wooden furniture, etc. 䡬 Shining synthetic resin or ebonite products.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate.

2. Power switch

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.

3. Extension cord

When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

WARNING: Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Check your working environment

Ensure the following before operation;

䡬 No flammable gas, liquid, or object at worksite. 䡬 Take appropriate noise preventive measures to prevent adverse affects on the

environment by electrical noise.

䡬 Clear the area of children or unauthorized personnel.

6. Check mounting of the wool bonnet.

Mount the wool bonnet properly.

CAUTION:Improper fitting of the wool bonnet may cause vibration.

7. Fixing the side handle

Screw the side handle into the housing.

8. Check the lock lever.

Make sure that the lock lever is disengaged by pushing the lock lever two or three times before turning on the polisher (Fig. 2).

English

POLISHER OPERATION

1. Hold the polisher firmly by its housing and side handle (Fig. 1).

The polisher produces a counterforce which must be controlled by firmly holding onto the polisher.

2. Switch operation

This enables the polisher always to be controlled with the hand gripping the machine for maximum safety during polishing operations. <Intermittent use>

Switch ON: Press the switch trigger. Switch OFF: Release the switch trigger.

Switch ON: Press the switch trigger. The switch trigger is locked by pushing on

the locking button.

Switch OFF: Press and release the switch trigger.

3. Use light polishing pressure.

There is no need to press hard when polishing. Usually the polisher’s own weight is sufficient to allow the required light contact with the surface to be ground.

CAUTION: Do not press the polisher forcibly against the surface to be ground. Heavy

pressure can damage the surface being ground or damage the polisher’s motor.

4. Use of polishing compound or wax

Depending on the finishing degree of the surface, use the polishing compound or wax. In order to attain the maximum polishing effect, first polish the surface with the fine sand paper using the sander, then polish it with the polishing compound using the wool bonnet, and then finish with wax. Apply a small quantity of the compound and wax to the surface, and polish with the wool bonnet.

5. Beware of the cord during operation

CAUTION: Do not let the cord touch the wool bonnet during its operation, for the

rotating wool bonnet may catch the cord and roll it in.

6. Precaution after use

CAUTION: Do not lay the polisher down immediately after using on a place where there

are many shavings, much dirt and dust until it has completely stopped revolving. If the polisher is laid down with the wool bonnet turned downward before it has completely stopped revolving, there is a risk that the material may be damaged and the polisher may run wild, resulting in injury.

English

WOOL BONNET ASSEMBLY AND DISASSEMBLY

WARNING: Never attempt to assemble or disassemble the wool bonnet while the

polisher is capable of being turned “ON”. Be sure power switch is in the “OFF” position and the electrical cord has been disconnected from the receptacle.
