workpiece from slipping, but do not steady it with your foot or allow another person to
hold it.
•
When cutting round items, always secure them against rotation.
•
When using synthetic resin cutting discs, always observe the following:
Caution:
o
Synthetic resin cutting discs can absorb moisture.
o This moisture can cause the disc to become unbalanced at high speed. This
imbalance can cause the disc to break.
o
Do not cool resin cutting discs with water or other fluids.
o Do not expose resin cutting discs to high humidity or rain!
Do not use resin cutting discs past their use-by date (expiration date)! The date (quarter and
year) is stamped on the disc's arbour ring.
Example: 04/2020. This cutting disc can be used through the end of the fourth quarter of
2020 if properly stored and correctly used.
