2. Disassembling 

 

Follow the above procedures in reverse.

CAUTION:

  Con

fi

 rm that the depressed center wheel is 

mounted 

fi

 rmly.

Con

fi

 rm that the lock pin is disengaged by 

pushing lock pin two or three times before 

switching the power tool on.

MAINTENANCE AND INSPECTION

1.  

Inspecting the depressed center wheel

 

Ensure that the depressed center wheel is free of cracks 

and surface defects.

   Replace the depressed center wheel when it has been 

worn out to about 60 mm in external diameter.

2.  

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.

3.  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.

4.  Inspecting the carbon brushes (Fig. 3)

  The motor employs carbon brushes which are 

consumable parts.

  When they become worn to or near the “wear limit”, it 

could result in motor trouble. When an auto-stop carbon 

brush is equipped, the motor will stop automatically.

 

At that time, replace both carbon brushes with new ones 

which have the same carbon brush numbers shown in 

the 

fi

 gure. In addition, always keep carbon brushes clean 

and ensure that they slide freely within the brush holders.

5.  Carbon Brush Replacement

<Disassembly>

(1) Loosen the D4 tapping screw fastening the brush cover 

and remove the brush cover from the handle (

Fig. 4-A

).

(2)  Use a small screwdriver or similar tool, to shift the end of 

the spring holding the carbon brush toward the outside of 

the brush holder (

Fig. 4-B

).

(3) Remove the carbon brush from the brush holder, grasp 

the pigtail and disconnect the carbon brush plug by 

pulling out (

Fig. 4-B

).

<Assembly>

(1) Use a small screwdriver, etc., to insert the carbon brush 

plug into the brush holder terminal (

Fig. 4-C

).

(2)  Insert the carbon brush into the brush holder, use a small 

screwdriver or similar tool, to shift the end of the spring 

onto the top of the carbon brush (

Fig. 4-D

).

NOTE:

  Make sure the end of the spring is not holding the 

pigtail (

Fig. 4-E

).

(3)  Engage the brush cover on the handle and tighten the D4 

tapping screw.

NOTE:

  Make sure the pigtail is not pinched by the brush 

cover.

CAUTION

  In the operation and maintenance of power tools, the 

safety regulations and standards prescribed in each 

country must be observed.

NOTE

Due HiKOKI’s continuing program of research and 

development, the speci

fi

 cations herein are subject to change 

without prior notice.

PRACTICAL GRINDER APPLICATIONS

1.  Since grinding by utilizing only the grinder’s own weight 

is feasible, the grinder should never be pressed forcibly 

against the plane to be ground Hold the grinder lightly so 

that it only slightly contacts the plane to be ground.

   Heavy pressure will reduce the revolving speed and 

such deteriorate the 

fi

 nished surface, and phenomena as 

overload will lead to burning out of the motor.

2

.    Do not utilize the grinder entire surface when grinding. 

Use only its peripheral surface by tilting the wheel at an 

angle of 15-30°, as shown in 

Fig. 1

.

3

.  When a grinder equipped with a new depressed center 

wheel is pushed forward (direction A), the wheel edge 

may occasionally cut into the material to be ground. 

Always pull it backward (direction B) in this instance.

   However, once the depressed center wheel angle has 

been adequately abraded, both forward and backward 

operations are permissible.

4

.  The provided depressed center wheel (resinoid wheel) is 

rated as Class A grain and #36 grain size.

    Accordingly, its range of applications cover a wide 

variety, proving to be most suitable for heavy grinding 

of general steel materials. Since the wheel grain size 

is rather coarse, creating a 

fi

 ne-surfaced 

fi

 nish is very 

di

  cult.

  

 In this instance, hold the grinder lightly as through trying 

to lift it, and apply grinding slowly at a constant low 

speed. Whereby a 

fi

 ne 

fi

 nish similar to that accomplished 

with a 

fi

 ne-grain depressed center wheel is obtainable.

5.  Switching on the grinder

 

The switch can be turned ON by turning its lever ON side, 

or turn OFF by turning its lever to the OFF side.

6.  Precaution after use

  Do not lay the grinder down immediately after use in a 

place where there are many shavings and much dirt and 

dust until it has completely stopped revolving.

CAUTION 

  Shock to the main body can be the cause of cracks or 

splits in the depressed center wheel. Be especially careful 

to avoid sudden shocks when using the equipment.

 

 If the main unit is accidentally bumped or dropped, make 

a careful check for cracks or splits on the depressed 

center wheel before further use.

  Do not press the lock pin when the equipment is turning. 

Also, do not turn on the switch when the lock pin is 

pressed down.

ASSEEMBLING AND DISASSEMBLING THE 

DEPRESSED CENTER WHEEL (Fig. 2)

CAUTION

  Be sure to switch power OFF and disconnect the 

attachment plug from the power receptacle to avoid 

serious trouble.

1.  Assembling (Fig. 2)

(1)  Turn the equipment upsidedown so that the spindle will 

be facing up.

(2)   Mount the wheel washer onto the spindle.

(3) Fit the protuberance of the depressed center wheel or 

diamond wheel onto the wheel washer.

(4)  Assemble the wheel nut onto the spindle. 

 

(For diamond wheel assembling, use the wheel nut with 

the convex side against the diamond wheel.)

(5) Insert the push button to prevent rotation of the spindle, 

and tighten the wheel nut securely with provided wrench, 

as shown in 

Fig. 2
