Always use a work piece that is at least 3/8” (9 

mm) thick.

 The work piece must be at least 3/8” (9 mm) thick. If 

a work piece is too thin, the magnetic power of your 

machine will decrease. This will cause the machine 

to move during operation. This could result in an 

accident. (Fig.3)

Not less than 3/8" (9mm)

Use an iron back-up plate.

 If the work piece is less than 3/8” (9 mm) thick, you 

must use an iron back-up plate that is more than 

13/32”(10 mm ) in thickness. The surface area of the 

iron back-up plate must he greater than the surface 

area of the Magnet. An appropriate back-up plate is 

necessary to boost the holding power of the Magnet. 

(Fig.3)

  Use of an inappropriate back-up plate can result in 

an accident, If the back-up plate is not thick enough 

or big enough, the machine will come loose during 

operation. This can result in an accident and severe 

injuries.

Less than 3/8" (9mm)

Always keep surfaces clean.

 Always keep the Magnet surface clean. Always keep 

the work piece surface clean. If there are any foreign 

objects between the Magnet and the work piece 

surfaces, this will reduce magnetic power. This could 

cause the machine to move during operation. This 

can result in an accident. Keep all surfaces clean of 

rust, chips or other foreign material.

Do not place the machine over a hole.

 Do not attempt to position the Magnet over a hole. 

Attempting to straddle a hole will reduce the power 

of the Magnet. This will cause the work piece to 

come loose during operation and can cause an 

accident.

Always use a Chain to secure the machine.

 If the machine falls, it can cause severe injuries. 

There is always a possibility that magnetic power 

can be lost or reduced because of a power failure. 

Magnetic power can be lost on rough surfaces. You 

must take precautions to prevent the machine from 

falling.

 This machine comes with the Chain. The Chain is 

to be used to fasten the machine to the work piece. 

If you do not use the Chain, it is possible that the 

machine may fall. (Fig.4)

 If use of the Chain is not possible because of the 

size of the work piece, you must use another method 

of securing the machine. Use a Supporting Magnet 

Assʼy

 to prevent the machine from falling.

 The use of a Supporting Magnet Ass

ʼ

y is shown 

below. (Fig.5)

Always set the Magnet in the proper position.

 Always set the Magnet parallel to the longitudinal 

direction of the material. Failure to set the Magnet in 

the proper position may result in reduced magnetic 

power. This can cause the machine to move in 

operation. This can cause an accident resulting in 

severe injuries.

 When using on H-section steel, as shown in the 

figure below, set the Magnet in a direction parallel 

to the longitudinal direction of the material. This will 

ensure that the Magnet is in the best position for 

magnetic attraction.(Fig.6)

 Poor magnetic power may result in damage to the 

cutter or damage to the work piece.
