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

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:

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 Removal of casting fin and finishing of various type of steel, bronze and aluminum

materials and castings.

䡬 Grinding of welded sections or sections cut by means of an acetylene torch.

䡬 Grinding of synthetic resins, slate, brick, marble.

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.

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 Grinding thin steel sheet may cause a high booming sound.

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

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. Mounting the wheel guard

Be sure to mount the wheel guard at an angle that will protect the operator’s body from

injury by a broken wheel piece.

WARNING: If not correctly attaching a proper wheel guard, it may lead to severe

injury or death if the depressed center wheel should be broken.

English

7. Inspect the depressed center wheel carefully before mounting.

Thoroughly check that a specified depressed center wheel free of cracks and splits is

mounted. Make sure that the depressed center wheel is firmly clamped and has been

mounted in accordance with the instructions contained on page 13.

8. Test the grinder before using.

Before actually beginning the grinding work, test the grinder by first clearing the area of

all other personnel. Make sure the wheel guard is in place and that you are wearing eye

protection. Turn the grinder “on”, and make sure the grinder runs smoothly and shows

on abnormalities.

Duration of the trial run is as follows:

When depressed center wheel is replaced .................. 3 minutes or more

When starting daily work .............................................. 1 minute or more

9. Use only properly rated depressed center wheels.

Use only depressed center wheels rated at 13700 RPM or more for G10SR and 13300 RPM

or more for G12SR.

Using a depressed center wheel rated less can lead to wheel disintegration during

operation and serious bodily injury.

10.Check the lock pin.

Make sure that the lock pin is disengaged by pushing lock pin two or three times before

turning on the grinder.

GRINDER OPERATION

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

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

grinder.

2. Turn the grinder “on”.

While holding the grinder firmly, use one finger to slide the switch to the “on” position.

3. Use light grinding pressure.

There is no need to press hard when grinding. Usually the grinder’s own weight is

sufficient to allow the required light contact with the surface to be ground.

WARNING: Do not press the grinder forcibly against the surface to be ground. Heavy

pressure can result in wheel breekage and serious injury. It can also

damage the surface being ground or damage the grinder’s motor.

4. Use proper grinding angle.

Grind only with the wheel’s edge by lifting the grinder 15° to 30°, as shown in Fig. 2.

CAUTION: Do not use the entire surface of the depressed center wheel. Use only the

edge of the depressed center wheel.

English

5. Move the grinder in the proper

direction.

When using a new depressed center

wheel in direction A (Fig. 2), the

wheel edge may cut into the

workpiece. In this case, grind in

direction B (Fig. 2).

Once the wheel edge is worn, the

workpiece can be ground in both

directions.

NOTE: The wheel provided (resinoid wheel) is rated as Class A grain and # 36 grain size. It

is most suitable for heavy grinding of steel and other types of materials.

6. Adjust operation to desired finish.

For a fine finish, decrease pressure by lifting slightly. Grind slowly and at the appropriate

speed.

CAUTION: The revolving depressed center wheel will creste air turbulence.

Do no lay the grinder down in areas of dust or dirt until it has come to a

complete stop.

DEPRESSED CENTER WHEEL ASSEMBLY AND DISASSEMBLY

WARNING: Never attempt to assemble or disassemble the depressed center wheel

while the grinder 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.

1. Assembling

(1) Turn the disc grinder upsidedown so that

the spindle is facing upward.

(2) Align the oval-shaped indentation of the
