Depressed Centre Grinding Wheel
Flat Cutting-Off Wheel
Prolonged absorption of dust generated during grinding operations may induce
pneumoconiosis.
Sparks generated during grinder use may cause burn and fire.
Injury or death accidents due to direct attack on the human body of broken and scattered
grinding wheel fragments
Grinding wheel fragments broken and scattered around during grinding operations, if they
strike the human body, may cause serious injury or death.

SECTION 4. FIRST AID MEASURE
Eye Contact:
Skin Contact:
If dust enters the eyes, wash the eyes immediately with clean running water. Do not press hard nor rub
them. Get medical treatment if necessary.
Flush with soapsuds etc. after the end of operations.
Inhalation:
Ingestion:
In the case of dust inhalation, remove the victim immediately to a place of fres h air. Gargle (wash) with
water. Get medical treatment if necessary.
Give large amounts of moisture and induce vomiting. Get medical treatment if necessary.
SECTION 5. FIRE FIGHTING MEASURES
Extinguishing Methods:
Choke extinguishing method. (May be incombustible under normal conditions.)
Use water, powder, carbon dioxide, foam extinguishers, etc. for early-stage fire.
Use water and foam extinguishers to cool and block air for large scale fire.
Gases generated under heating contain hazar do us su bst a nces. Wear respiratory protectors for
firefighting.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Do not use abrasive products near flammable materials.
SECTION 7. HANDLING AND STORAGE
Handling:
(1) Do not drop, (2) do not bump, (3) do no t tur n over during handling.
Before installing on the machine, perform visual tests for grinding wheel crack, breakage, chip, etc.
Make sure that maximum operating peripheral speed, dimensions, etc. conform to the machine.
Do not use in excess of the maximum operating peripheral speed labeled on grinding wheel.

Page 3
CONTINUED: SECTION 7. HANDLING AND STORAGE
Handling:
When installing grinding wheel on the flange, use proper flange and do not fasten nuts too tight.
Perform correct installation on the flange.
When installing on the flange, perform visual checkup without fail and make sure the absence of any
abnormality. Perform test runs for 1 minute or more before start of operations for the day and for 3
minutes or more when grinding wheel is installed and/or replaced.
Keep the body from direct contact with grinding wheel under rotation.
Store in a dry place using pigeonholes etc.
Do not store in a place of possible moisture freezing.
Use the designated side only. (Prohibit use of the side face)
Storage:
Absorption of moisture and humidity lowers grinding wheel strength. Store in a dry place of good
ventilation avoiding humidity.
SECTION 8. EXPOSURE CONTROLS AND PERSONAL PROTECTION
Allowable Levels:
Control Levels:
Installation Measures:
Class 2 dust, Inhalable dust = 1 mg/m
Total dust = 4 mg/m
2.9 mg/m
3
(as mineral dust)
3
Japan Society of Industrial Hygiene (1990 Edition)
ACGIH (1990 Edition) 10 mg/m
As dust-proof measures, install dust collectors or arrange general exhaust if necessary. Dust collectors
may generate and absorb sparks and induce fire. Take measures so that they do not absorb sparks
directly

Protectors:
Operators should wear the following protectors without fail.
Respiratory protectors ... Dust masks passing national tests.
Protective goggles ... Complete protection type dust goggles.
Protective gloves ... Spark-proof gloves.
Protective clothes ... Work clothes of spark-proof materials.
Others ... Soundproof ear plugs, helmets, safety shoes, etc.

SECTION 13. DISPOSAL CONSIDERATIONS
Dispose of wastes in accordance with applicable regulations. (Follow national, prefectural and regional laws and regulations.)
Specify the contents and commission the disposal with licensed industrial waste disposers. Classified as "glass wastes and pottery
wastes". Dispose as industrial wastes.
SECTION 14. TRANSPORT INFORMATION
Take care to avoid water soaking and packing case damage.
Place in boxes resistant to some degrees of pressure and shock.
Avoid rough handling to prevent grinding wheel from breakage.
Transport free from turnover, fall, other impact, etc.
"Fragile" Avoid dumping and impact such as fall.
Inform the manufacturer or user when abnormal impact, force, etc. have supposedly been added.
