APPLICATIONS

  Removal of casting 

fi

 n and 

fi

 nishing of various types of 

steel, bronze and aluminum materials and castings.

  Grinding of welded sections or sections cut by means of 

a cutting torch.

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

  Cutting of synthetic concrete, stone, brick, marble and 

similar materials.

PRIOR TO OPERATION

1. Power source

  Ensure that the power source to be utilized conforms 

to the power requirements speci

fi

 ed on the product 

nameplate.

2. Power switch

  Ensure that the power switch is in the OFF position. If 

the plug is connected to a 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 su

  cient thickness and rated 

capacity. The extension cord should be kept as short as 

practicable.

4.  Fitting and adjusting the wheel guard

 

The wheel guard is a protective device to prevent injury 

should the depressed center wheel shatter during 

operation. Ensure that the guard is properly 

fi

 tted and 

fastened before commencing grinding operation.

[Installing and adjusting the wheel guard]

  Open the lever and insert the locating pin of wheel 

guard,  bringing  it  into  line  with  the  across 

fl

 ats  of 

packing ground.

  Then, turn the wheel guard to a desired position (for 

use).

  Close the lever and 

fi

 x it. If and when required, carry out 

adjustments by tightening or loosening the screw.

  If the lever does not move smoothly, apply some 

lubricating oil to the sliding section between the set 

piece and the lever.

  Fasten the wheel guard at the position where the across 

fl

 ats of the wheel guard positioning pin and packing 

ground are aligned (the position where the wheel guard 

is inserted), but do not use it.

5.

  Ensure that the depressed center wheel to be utilized is 

the correct type and free of cracks or surface defects. 

Also ensure that the depressed center wheel is properly 

mounted and the wheel nut is securely tightened. Refer 

to the section on “Assembling and  Disassembling the 

Depressed Center Wheel”.

6.  Conducting a trial run

 

Ensure that the abrasive products is correctly mounted 

and tightened before use and run the tool at no-load 

for 30 seconds in a safe position, stop immediately if 

there is considerable vibration or if other defects are 

detected. 

 

If this condition occurs, check the machine to determine 

the cause.

7. Con

fi

 rm the spindle lock mechanism

 Con

fi

 rm that the spindle lock is disengaged by pushing 

push button two or three times before switching the 

power tool on (See 

Fig. 1

).

8.  Fixing the side handle

 

Screw the side handle into the gear cover.

PRACTICAL GRINDER APPLICATION

1. Pressure

  To prolong the life of the machine and ensure a 

fi

 rst 

class 

fi

 nish, it is important that the machine should not 

be overloaded by applying too much pressure. In most 

applications, the weight of the machine alone is su

  cient 

for e

 ective  grinding.  Too  much  pressure  will  result  in 

reduced rotational speed, inferior surface 

fi

 nish,  and 

overloading which could reduce the life of the machine.

2. Grinding angle

 

Do not apply the entire surface of the depressed center 

wheel to the material to be ground. As shown in 

Fig. 3

the machine should be held at an angle of 15° – 30° so 

that the external edge of the depressed center wheel 

contacts the material at an optimum angle.

3.

  To prevent a new depressed center wheel from digging 

into the workpiece, initial grinding should be performed 

by drawing the grinder across the workpiece toward the 

operator (

Fig. 3 direction B

). Once the leading edge 

of the depressed center wheel is properly abraded, 

grinding may be conducted in either direction.

4.   Switch operation

  Switch ON:  Push the locking button forward and then 

press the switch lever.

 

 

* For continuous use, press the switch lever. 

The switch lever is locked by pushing 

the locking button forward once again.

(*Subject to change depending on area.)

 

Switch OFF: Press and release the switch lever.

5.  Precautions immediately after 

fi

 nishing operation

 

After switching o

  the machine, do not put it down until 

the depressed center wheel has come to a complete 

stop. Apart from avoiding serious accidents, this 

precaution will reduce the amount of dust and swarf 

sucked into the machine.

CAUTION

  Check that the work piece is properly supported.

  Ensure that ventilation openings are kept clear when 

working in dusty conditions.

  If it should become necessary to clear dust, 

fi

 rst 

disconnect the tool from the mains supply (use non-

metallic objects) and avoid damaging internal parts.

  Ensure that sparks resulting from use do not create 

a hazard e.g. do not hit persons, or ignite 

fl

 ammable 

substances.

  Always use eye and ear protection.

  Other personal protective equipment such as dust 

mask, gloves, helmet and apron should be worn when 

necessary.

 

If in doubt, wear the protective equipment.

  When the machine is not use, the power source should 

be disconnected.

ASSEMBLING AND DISASSEMBLING THE 

DEPRESSED CENTER WHEEL 

CAUTION

  Be sure to switch OFF and disconnect the attachment 

plug from the receptacle to avoid a serious accident.

1.  Assembling (Fig. 1)

(1) Turn the machine upside down so that the spindle is 

facing upward.
