When purchasing an attachment such as a grinding disc, cut-off wheel, or polishing pad, always ensure that the maximum rated RPM of the attachment is equal to or greater than the maximum speed of your tool, whether the tool is pneumatic or electric. Using an attachment with an insufficient speed rating may result in serious injury due to attachment failure.
Identifying the Maximum Tool RPM
Pneumatic tools:
The maximum speed is typically indicated directly on the tool label as free speed (n/min or RPM).
AC Electric tools:
Many electric tools display the maximum RPM on the specification label. If the RPM is not listed, it can be estimated using the following formula:
N(RPM)=120×Frequency (Hz)/P(Number of motor poles)
Next, calculating Attachment Peripheral Speed
To determine the maximum circumferential (peripheral) speed of the attachment when used with your tool, use the following formula:
V (m/s)=π×D (disc diameter in mm)×n (tool free RPM)/60,000
Safety Comparison
Compare the calculated speed V (m/s) with the maximum allowable speed marked on the attachment (referred to as Vd).
If Vd < V → DO NOT USE this attachment. It is not designed for the tool speed and may fail.
If Vd ≥ V → The attachment is suitable for use with the tool.
Important Safety Reminder
Safe operation involves more than speed compatibility. Users must also understand:
Proper use of the grinder guard
Correct grinding angle and permitted contact surfaces
Mounting procedures and inspection before use
Tool handling and personal protective equipment (PPE)
Always read and understand the tool manufacturer’s instructions before operation to ensure maximum safety and efficiency.

[AC Motor Maintenance Guide (For Air Compressor Operators)]
If your air compressor runs on an AC motor, this is a guide to show you how to keep the motor nice and efficient.
1. Daily / Regular Checks
*Keep it clean
Wipe off dust, oil, and dirt. Make sure the cooling vents are not blocked.
*Listen while running
Watch for unusual noise, vibration, or smell. Stop the machine if anything seems abnormal.
2. Weekly / Monthly Checks
*Check electrical connections
Make sure cables and terminals are tight and not damaged or burnt.
*Check motor temperature
The motor should feel warm, not extremely hot.
Overheating means something is wrong.
*Check mounting and alignment
Ensure the motor pulley is firmly mounted and properly aligned with the compressor pump's pulley.
3. Periodic Maintenance
Lubricate if required. Replace bearings if you hear grinding or whining noises.
Confirm voltage and frequency match the motor nameplate.
4. Safety Reminder
Always turn off and lock out power before inspecting or servicing the motor.
Regular checks help prevent breakdowns, improve efficiency, and extend motor life.

For Those Performing Grinding and Cutting Work
Special training and certification are legally required in countries such as Japan when performing grinding or cutting work for professional purposes using pneumatic or electric grinders, rotary tools, or sanders.
For DIY or personal use, this training is not mandatory; however, it is strongly recommended to ensure operator safety and proper, efficient tool use.
Safety First!

Can an air compressor explode?
Yes—though it’s rare.
It usually happens due to:
• Over-pressure (failed pressure switch or blocked safety valve)
• Rust inside the tank from not draining moisture
• Overheating in poor ventilation
• Electrical faults or bad repairs
• Flammable vapors nearby
How to prevent it:
Drain the tank, keep good ventilation, avoid flammables, and check the safety valve.
Stay safe and maintain your compressor!
