i)  Support panels or any oversized workpiece to 

minimize the risk of wheel pinching and kickback. 

Large workpieces tend to sag under their own weight. 

Supports must be placed under the workpiece near the 

line of cut and near the edge of the workpiece on both 

sides of the wheel.

j)  Use extra caution when making a “pocket cut” into 

existing walls or other blind areas.

 The protruding 

wheel may cut gas or water pipes, electrical wiring or 

objects that can cause kickback.

PRECAUTIONS ON USING CUTTER

1.   Do NOT use any cutting tool other than a diamond 

wheel.

2.   Don’t use it for cutting of metallic materials. Diamond 

wheel may be broken or its service life may be 

remarkably reduced when it is used for cutting of 

metallic materials . Be sure not to use the wheel for 

cutting of metals.

3.   Be  sure  to  take  an  earth  leakage  breaker  or  isolating 

transformer as electric shock-preventive measures.

4.   Pour on water while cutting or scribing concrete, tile or 

stone.

5.   Keep the motor interior free of water.

6.   Wear protective glasses to protect your eyes while 

cutting.

7.   Prior to use, be sure to check the diamond wheel in such 

details as crack, broken part, bent part and the like. 

Don’t use a diamond wheel if any of the above detect 

is found on the wheel. Also con

fi

 rm that no abnormality 

exists by actual test running.

8.   Proceed with cutting operation when full speed has 

been reached.

9.   Do NOT apply excessive force.

10.  When cutting concrete, tile, or stone, the maximum 

cutting depth should be held to within 20mm.

11.  Never touch diamond wheel while operating.

12.  Never lay down the cutter while the diamond wheel is 

revolving.

13.  Exercise care to position the cutter at a safe, stable spot 

when cutting.

14.  Take good care of the power tool and keep it clean.
