Frequently Asked Questions - SV 8SA HITACHI

How do I change the sanding paper on the Hitachi SV 8SA?

To change the sanding paper, first ensure the sander is unplugged. The SV 8SA uses a clamp system or hook-and-loop pad, depending on the model. For clamp type, loosen the clamps, remove the old paper, insert new paper, and tighten clamps. For hook-and-loop, simply peel off and stick on new paper.

Can I use the SV 8SA for wet sanding?

No, the Hitachi SV 8SA is designed for dry sanding only. Using it with water or other liquids can damage the tool and create an electrical hazard.

What is the orbit diameter of the SV 8SA?

The orbit diameter is 1.6 mm, which provides a fine finish suitable for sanding between coats of paint or varnish.

How do I connect a vacuum cleaner to the dust port?

The dust port is compatible with a standard 35 mm vacuum hose adapter. Simply attach the adapter (if needed) and connect your vacuum hose. Ensure the vacuum is turned on during use for effective dust extraction.

Why does my sander vibrate excessively?

Excessive vibration may be due to a worn sanding pad or unbalanced paper. Check the pad for wear and replace if necessary. Also ensure the sanding sheet is properly centered and attached.

How often should I replace the carbon brushes?

Carbon brushes should be checked every 50-100 hours of use. Replace them when they are worn down to about 6 mm in length. Always use genuine Hitachi brushes.

Can I use the sander without the dust bag?

Yes, but it will create a lot of dust. It is recommended to always use the dust bag or connect a vacuum for health and cleanliness. Operating without dust collection may also clog the internal vents.

What is the maximum sanding speed?

The SV 8SA operates at a fixed speed of 14,000 orbits per minute (OPM). It does not have variable speed control.

How do I clean the dust bag?

Empty the dust bag regularly. For a thorough clean, tap the bag gently and use a soft brush to remove fine dust. Do not wash the bag as it may damage the filter.

Is the Hitachi SV 8SA suitable for removing paint?

It is best for fine sanding and finishing. For heavy paint removal, use a coarse grit paper (e.g., 40-60 grit) but be aware it will be slower than a belt sander. The sander is not designed for aggressive material removal.

PRIOR TO OPERATION

1. Power source

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

2. Power switch

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

3. Extension cord

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

4. Installing the sanding paper

(1) Bending the sanding paper:

Position the sander with its pad side facing upward as shown in Fig. 1. Place the sanding paper on the pad so that the center of the sanding paper is aligned with the center of the pad, and bend both ends of the sanding paper at a 90° angle. Then, bend both ends again in the manner shown in Fig. 2. The sanding paper is now ready to be installed on the sander.

(2) Installing the sanding paper:

While ensuring that the cord is not bent, place the sander on a workbench as shown in Fig. 3, and insert one end of the sanding paper (bent section). Next, insert the remaining bent section in the same manner.

CAUTION

The sanding paper must be precisely installed on the pad, ensuring that there is ample tension (leaving no slack). Loosely installed sanding paper could result in unevenly sanded surfaces and/or damage to the sanding paper itself.

5. Attaching and Removing the Dust Bag

(1) Attaching the Dust Bag

As shown in Fig. 4, hold the dust gate and push it in the direction of Arrow A to attach it to the dust outlet.

(2) Removing the Dust Bag

As shown in Fig 4, hold the dust gate and pull it in the direction of Arrow B to remove it from the dust outlet.

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

The power can be turned on by setting the lever to ON (1) and turned off by setting the lever to OFF (0).

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.

2. How to hold the orbital sander

While gripping the housing, lightly press the sander against the surface to be sanded so that the sanding paper uniformly contacts the surface, as shown in

Fig. 5. 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 lowered sanding or polishing efficiency.

3. How to move the orbital sander

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

4. 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.

MOUNTING THE OPTIONAL ACCESSORIES

1. Attaching a Sponge Pad (Velcro type) or a Stick-on Pad

Loosen the M4 x 10 screws (4) and remove the attached pad. Next, attach a sponge pad (Velcro type) or a stick-on pad.

CAUTION

Replace the pad only. Use the other parts without removing them.

2. Attaching Velcro Type Sanding Paper or Stick-on Type Sanding Paper

Match the sanding paper's hole with the pad's hole and strongly push the sanding paper with the palm of your hand to fasten it securely in place.

3. When collecting dust with the Dust Collector (Model WDE-1200)

By attaching the Dust Collector (Model WDE-1200), it is possible to carry out clean sanding.

As shown in Fig. 6, attach the adapter, hose and dust collector in order to the dust outlet.

4. Making a Hole in the Sanding Paper with the Punch Plate (Fig. 7)

When using sanding paper without holes in it, punch holes in it with the punch plate to improve dust collecting capacity.

MAINTENANCE AND INSPECTION

1. Emptying and cleaning the Dust Bag

If the dust bag contains too much saw dust, dust collection will be affected. Empty the dust bag when it gets full.

Remove the dust bag, open the fastener, and dispose of the contents.

2. Inspecting the sanding paper

Since use of worn-out sanding paper will degrade efficiency and cause possible damage to the pad, replace the sanding paper as soon a excessive abrasion is noted.

3. 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. Failure to do so could result in serious hazard.

4. 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.

5. Servicing

Consult an authorized Service Agent in the event of power tool failure.
