Hot chips/filings may fly out from the work piece. 
Always wear safety glasses, dust mask, earplugs, 
gloves (except knitted gloves) and long-sleeved 
garment.
Keep your face well away from the work piece.

 Do not use any Grinding Wheel with the rated 

speed (r/min) that is lower than the actual 
no load speed of the grinder. Make sure the 
dimensions of the Grinding Wheel you are using 
is applicable to the specification of the grinder.

 Make sure there are no cracks, chips or damage 

to the Grinding Wheel prior to use. Do not use 
any wheels wet or without labels.

 Use Nitto Kohkiʼs Wheel Flanges only. However, 

do not use any of them which have cracks, chips 
or worn. Do not use the alternative flanges or flat 
washers.

 Make sure if the Grinding Wheel is adaptable to 

the Wheel Flanges.

Do not use reducing bushing to meet the Wheel 
Lock unless they are supplied by the Grinding Wheel 
manufacturer.

 Make sure there are no cracks, distortion or wear 

marks on the thread of the Spindle or Wheel Lock.

The label on the wheel has to be the same or bigger 
diameter than that of a Spindle.

 Make sure if there is any cracks, distortion or 

worn on a thread of a Spindle or Wheel Lock.

Do not use the grinder if you ever find one.

 Do not use the side of the Grinding Wheel (except 

for specific side use Grinding Wheels) 

 Always use the Wheel Guard for the grinder if 

the maximum diameter of the Grinding Wheel is 
over 50mm.

 Use the Wheel Guard provided.

Failure to do so could result in injury.

 Replace damaged, bent or severely worn Wheel 

Guard. Do not use any Wheel Guard which can 
damage the Grinding Wheel.

 Air pressure for the grinder must not exceed 

0.6MPa (6kgf/cm

2

).

 Do not start or stop grinders suddenly.

Open a Throttle Lever gradually when you start 
operation.

 After a grinder has been repaired and returned, 

check the no load speed with a tachometer 
before you use to make sure its actual speed 
at 0.6MPa (6kgf/cm

2

) does not exceed the rated 

speed printed on the Wheel Guard. Do the same 
check after each stage of the work process of 
work even in normal use. Set the Adjust Valve to 
the maximum speed position when you check 
the no load speed.

 Only qualified/trained operators should attach 

or replace Grinding Wheels as well as checking/
testing them.

 Release the Throttle Lever when air supply is 

stopped.
