CAUTION • When using with large or heavy instruments, make sureholding force from the magnet is adequate to hold thegauge secure.
• If holding force is insufficient, base may fall unexpectedly
and cause damage to equipment.
• When using the Arbor attachment, use special care. Basemay be unstable in certain mounting positions.

SAFETY WARNINGS
１．Strong magnetic field is present.

• Keep away from watches and precision instruments, and fromcomputers and recording media. When brought close, magnetic
field may cause damage or destroy recorded data.
• Persons using pacemakers or electronic medical devices should
not handle Magnetic Base. Strong magnetic field may be
dangerous.

２．Magnets create strong forces.

• Use caution when handling. Near metal, Base can suddenly
attract and pinch hand or body causing injury. Use appropriate
safety equipment, such as gloves when handling.

３．Holding force depends upon surface type.
•Please note that holding force will be reduced under the following
conditions:・ If surface is thin, the holding force will be reduced allowing
the base to easily come loose.
・ For surface materials other than mild steel plate.

• If surface is painted, or dirty, or if surface is uneven.
• The holding force is much greater than the force required toslide the Base. For vertical use, pay special attention to makesure Base will not slide.
• If used on slippery surface, or vibrating machinery, Base may
come loose more easily.
• Exposure to high temperatures may cause thermal
demagnetization reducing holding force.

４．
Confirm holding force before use.

• Cautiously check holding force before applying full weight toconfirm that attraction is sufficient for application.

５．Product is high power tool intended for use in industrial applications.
• If used in office or residential environment, please use caution.

６．Do not use or store in locations which are hot or have excessive
humidity. Magnetic strength may degrade, or magnet may
corrode affecting holding force.
