SAFETY
INFORMATION
Read this insert before mounting or using product. Follow tool's instructions, employer's safety rules,
ANSI B7.7 re: "Safety Requirements for Abrading materials with Coated Abrasive Systems", and any
other local standards. Operator must be properly trained.
Planning and Preparation
Prepare a safe work area
Check workpiece materials
Use only on Carbon Steel, Stainless Steel, Cast Iron, or Alloys of: Titanium,
Copper, Zinc, Chromium/Nickel, or Aluminum to reduce the risk of disc
breaking, re, explosion, or health hazards.
Read the Safety Data Sheets (SDSs) for the workpiece materials.
Respiratory hazard
Exposure to dust generated from workpiece and/or abrasive
materials can result in serious, permanent lung damage or other
injury. To reduce this risk:
• Use dust capture or local exhaust as appropriate.
• Wear all recommended protective equipment.
Fire and explosion hazard
Grinding produces sparks and heat. Keep away from anything
that can ignite or explode. Do not allow dust to accumulate.
Do not use on ammable or explosive materials.
Do not allow bystanders
Keep bystanders out of the work area. Disc fragments can be
thrown a long distance, and bystanders may also be exposed to
respiratory, re, and explosion hazards. If other people must be
nearby, ensure that they wear proper personal protective
equipment (PPE).
Always wear proper PPE as identi ed by your risk assessment to help
protect against dust, grinding sparks and debris, noise, and some disc
fragments:
• full face shield
• impact resistant protective eyewear marked
as ANSI Z87.1 conformant
• hearing protection
• NIOSH approved respirator
• gloves
• body and skin protection
Do not alter or modify the disc in any way.

3M™ TN and NTN Disc Products
Tool selection:
1. Use only on tools designed for discs.
2. Compare the maximum operating speed (RPM) rating of the tool
with the maximum RPM rating of the backup pad and disc. Make
sure the machine speed does not exceed the maximum operating
speed marked on the product or package (see example on this
page). Exceeding product's Max. RPM can cause it to break apart
SDS
and cause serious injury.
3. Use manufacturer's recommendations for use of tool guards.
Mounting:
1. Always use proper backup pad with disc.
2. Inspect backup pad and disc and replace if either are damaged.
Additional 4½" instructions:
1. Do not exceed 13,300 RPM operating speed.
2. TN Quick Change Back-up Pad (Cat. #51111 56573) must be used
with all 4½ in NTN attachments.
3. Thread back-up pad onto tool shaft and tighten securely. The end
of the tool shaft should be ush with the face of the back-up hub. (May
require adaptor or spacer [see below]. Adaptors that change the tool
shaft diameter to 5/8-11 tpi (threads per inch) are available for many
di erent shaft sizes).
4. Thread abrasives onto tool shaft and tighten against back-up pad.
5. Test in small area to determine best speed and pressure for the job.
6. To change abrasive, wait until tool has completely stopped.
7. Disconnect from the air supply. Shaft of tool should be ush with back-up pad.
If shaft of tool extends beyond grinding disc, spacers must be used as shown
between tool shaft and back-up pad.
Operation:
1. Direct disc away from your body and bring it up to operating speed before
grinding.
2. Stop immediately if vibration or wobbling occurs during use. Determine cause
and correct before continuing.
3. Follow good grinding practices:
• Secure workpiece.
• Keep all body parts and objects clear of grinding path.
• Begin grinding by gradually engaging workpiece.
• Never bump or force disc so that tool motor slows or stalls.
• Direct sparks away from face and body.
• Product that disengages from the backup pad may cause injury. Abruptly
stopping tool o work piece can cause the product to disengage from
the backup pad. Do not abruptly stop the product
o the workpiece.
• Do not use discs with abnormally curled or cupped shape.
Storage: Incorrect storage could a ect safety as well as product
performance. Protect disc when not in use. Never rest tool on disc. Store discs
in dry environment below 150°F (65°C) and limit exposure to water and high
humidity.
