WARNING: Avoid electrical shock hazard. Never use this tool with a damaged or frayed electrical cord or extension cord. Inspect all electrical cords regularly. Never use in or near water or in any environment where electric shock is possible.

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 and “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.

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 (refer to page 8). 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.

Consult an authorized electrician to make appropriate repairs.

If such a fautly receptacle is used, it may cause overheating, resulting in firing.

5. Check your working environment

Eusure the following before operation;

○No flammable gas, liquid, or object at worksite.

○Sanding thin steel sheet may cause a high booming sound.

In this case, place a rubber mat under the workpiece.

○Take appropriate noise preventive measures to prevent adverse affects on the environment by electrical noise.

○Clear the area of children or unauthorized personnel.

6. Installing the Sanding Papers

Insert a sanding paper while unfastening the spring as shown in Fig. 2. Align the sanding paper in parallel with the pad and pull it tight. Should the sanding paper be loosely mounted, the finishing will become uneven or the sanding paper may be damaged.

(To facilitate mounting the sanding paper)

After engaging the one side of sanding paper, fold the other side 3/8" (10mm) from the edge as shown in Fig. 3. Fold the sanding paper again 3/8" (10mm) from the folded edge.

PRACTICAL OPERATING PROCEDURES

CAUTION: Never apply water or grinding fluid when sanding. This could result in electrical shock.

1. Switching the sander ON and OFF

By pulling the trigger and pushing the stopper, the switch will remain ON even when the trigger is released, promoting continuous, efficient operation. By pulling the trigger again, the stopper is released and the switch is turned OFF.

CAUTION: Never turn the power switch ON when the sander is contacting the surface to be sanded. This is necessary to preclude damage to the material. The same applies when switching the power OFF.

1. How to hold the orbital sander

While gripping the knob with one hand and the handle with the other, lightly press the sander against the surface to be sanded so that the sanding paper uniformly contacts the surface. DO NOT apply excessive pressure to the sander while sanding. Excessive pressure may cause overload of the motor, reduced service life of the sanding paper, and lower sanding or polishing efficiency. Also, while sanding or polishing, never cover the ventilation port on the upper motor housing. This could cause overheating and subsequent damage to the tool.

1. How move the orbital sander

For optimum operating efficiency, alternately move the sander forward and backward at a constant speed and balance.

1. After installing new sanding paper

Movement of the sander may tend to become unsteady after new sanding paper has been installed, because of the new, coarse grain of the paper. This can be avoided by slightly tilting the sander forward or backward during sanding or polishing. Sander movement will become steady as the sanding paper surface becomes properly abraded.

HOW TO INSTALL THE OPTIONAL ACCESSORIES

1. Installing the dust cover

Position the dust cover as shown in Fig. 4. Engage the dust cover rear as shown in Fig. 5 and depress the dust cover front downward.

1. Installing the cleaner

Connect the suction hose to the dust cover hole. (If the suction hose cannot be connected, attach the supplied adaptor and fix with tape.)

MAINTENANCE AND INSPECTION

WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.

1. Inspecting the sanding paper

Since continuous use of worn sanding paper will definitely result in low sanding or polishing efficiency, replace it with new paper as necessary.

1. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately.

WARNING: Using this sander with loosen screws is extremely dangerous.

1. Maintenance of the motor

The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

1. Inspecting the carbon brushes

For your continued safety and electrical protection, carbon brush inspection and replacement on this tool should ONLY be performed by a HITACHI AUTHORIZED SERVICE CENTER.

1. Keeping after use

When not in use, the sander should be kept in a dry place out of the reach of children.

SERVICE AND REPAIRS

All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only genuine replacement parts will be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY.
