(The side handle can be secured in any position over 360°. Clamp tightly in normal manner by inserting the toothed end in the chuck wrench into the three key holes. CAUTION Securely hold the handle of the main body and the side handle when switching on as there is danger that your hands may be turned by force of reaction. Relationship between material to be drilled and optimum number of rotation The relationship between the material to be drilled and the optimum number of rotation may slightly differ depending upon the working condition, power supply situation, etc. Use the tool referring to TABLE 1 as a rough guide. For drill positioning, you will find it easier to work if you turn the dial once and set it to the low speed. CAUTION: If you exceed the standard values (optimum numbers of rotation) given in the table or engage in continued work for an extended period of time or perform a drilling job on soft materials, the motor may be subjected to an unreasonable load and may result in burnout. Especially, avoid such an abnormal way of use as a case where a drill stops during the drilling work. Adjust the number of rotation so that a smooth drilling job can be done at all times. [. . . ] CDrilling method by using Pilot Spigotv For easy positioning, carry out the following steps when using a diamond core bit. (1) Make a pilot hole at the center position of the material to be drilled with a 13 mm stone drill bit. CAUTION When drilling with a diamond core bit, there will be a high force of reaction load to your hands. Make sure to hold the handle of the main body and the side handle. [. . . ]
