Makita 6211DH Instruction Manual

When driving wood screws, predrill pilotholes to make driving easier and to pre-vent splitting of the workpiece.

Then proceed as follows.0 Drilling in woodWhen drilling in wood, best results are obtained with wood drills equipped with a guidescrew. The guide screw makes drilling easier by pulling the bit into the workpiece.To prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer a t the point to be drilled place the point of the bit in the indenta-tion and start drilling.Use a cutting lubricant when drilling metals. The exceptions are iron and brass whichshould be drilled dry.0 Drilling in metalCAUTION:*Pressing excessively on the tool will not speed up the drilling. In fact, this excessivepressure will only serve to damage the tip of your bit, decrease the tool performanceand shorten the service life of the tool.*There is a tremendous force exerted on the tool/bit a t the time of hole breakthrough.Hold the tool firmly and exert care when the bit begins to break through the workpiece.* A stuck bit can be removed simply by setting the reversing switch to reverse rotation inorder to back out. However, the tool may back out abruptly if you do not hold it firmly.*Always secure small workpieces in a vise or similar hold-down device.Recommended sizeof pilot hole lmml2.0 - 2.2 15/64'- 3/32")2.2 - 2.5 (3132'' - 3/32',)2.5 - 2.8 (3/32"- 7/64',)2.9 - 3.2(7/64"- ll8"I3.1 - 3.4 (1/8"- 9/64',)3.3 - 3.6 11/8" - 9/64',)3.7 - 3.9 19/64" - 5132'74.0 - 4.215/32"- 11/64,)4.2 - 4.4(11164'' - 11/64'l4.4 - 4.6111164' - 6/32',)Overload protectorThe overload protector automatically cuts out to break the circuit whenever heavy worki s prolonged. Wait 20 - 30 seconds before resuming operation.CAUTION :Always withdraw the tool from the workpiece before resuming operation. If the toolcannot be withdrawn, hold the tool firmly when turning on the tool, to overcome astrong reaction.9
