Maintenance - Makita DA301DW Betriebsanleitung

CAUTION:
• Pressing excessively on the machine will not speed
up the drilling. In fact, this excessive pressure will
only serve to damage the tip of your bit, decrease
the machine performance and shorten the service
life of the machine.
• There is a tremendous twisting force exerted on the
machine/bit at the time of hole breakthrough. Hold
the machine firmly and exert care when the bit
begins to break through the workpiece. Use both
hands to help control the machine.
• A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back
out. However, the machine may back out abruptly if
you do not hold it firmly.
• Always secure small workpieces in a vise or similar
hold-down device.
Screwdriving operation
Place the point of the driver bit in the screw head and
apply pressure to the machine. Start the machine.
Release the trigger just as the screw bottoms out. If
the trigger is not released, the screw may strip out the
hole or the screw and/or bit may be damaged.
NOTE:
• Make sure that the driver bit is inserted straight in
the screw head, or the screw and/or bit may be
damaged.
• When driving wood screws, predrill pilot holes to
make driving easier and to prevent splitting of the
workpiece. See the chart.

work is prolonged. Wait 20 – 30 seconds before
pressing the restart button to resume operation. Your
finger should not be on the trigger when you press the
restart button, however.
