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) Do not 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.
(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 eye protection. 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 from 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 tool's operation. If damaged, have the tool serviced by a HITACHI authorized service center 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 with another tool.
5. Service
(1) Tool service must be performed only by a HITACHI authorized service center. 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.
SPECIFIC SAFETY RULES AND SYMBOLS
- Hold tools by insulated gripping surfaces when performing an operation where the cutting tool 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.

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:
○Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed.
○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.

CAUTION: The dial cannot be rotated further than the “6” or “1” on the scale in their respective directions.
●For use as a Sander
- This unit is designed to provide sufficient polishing (sanding) power with the disc pressed lightly against the sanding/polishing surface: it is equipped with an electronic control circuit to ensure that the motor will not slow down even when loaded. There is therefore no need to press the sanding disc hard against the surface; doing so can overload the motor, subsequently causing the overload cut device to step into operation by cutting
the motor's power supply. If this should happen, cut the power switch and turn it back on to reset the unit: it will resume rotation at the correct motor speed.
-
Rather than applying the entire disc surface to the metal surface to be ground, use the sander by inclining it approximately 15^ 25^ to grind with the disc peripheral portion. (Fig. 3).
-
Precaution after use Do not lay the sander polisher down immediately after use in a place where there are many shavings and much dirt and dust until it has completely stopped revolving.

15° - 25°Fig. 3
●For use as a Polisher
-
Curved surface as well as plain one is treated for finishing. It is recommended to hold the polisher without pushing on the material, and make the best of its own weight as the excess pressure on the polishing surface will not only bring unsatisfactory result but also put unnecessary load on the motor.
-
Polishing compound or wax are used corresponding to the state of finishing and the maximum polishing effect will be attained when the following method is taken. Polishing with a sander using fine sanding disc.
Polishing with wool bonnet using compound substance final waxing.
First put the compound and wax in small quantity on the surface to be polished, then, give a polish with the wool bonnet.
CAUTION: Carefully guard against permitting the cord to touch the wool bonnet or sanding disc during operation. If the cord touches them, there is danger that it may become entangled.
ASSEMBLING AND DISASSEMBLING THE SANDING DISC AND WOOL BONNET
⚠ WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle to avoid serious trouble.
●For use as a Sander (Fig. 4)
(1) After placing the sanding disc on the rubber pad, thread the washer nut onto the spindle.
(2) Press the lock pin to secure the spindle and tighten the washer nut with a wrench.
