Reversing switch action
(Fig. 5 for DP4700 & Fig. 6 for 6402)
CAUTION:
• Always check the direction of rotation before drilling.
• Use the reversing switch only after the machine
comes to a complete stop. Changing the direction of
rotation before the machine stops may damage the
machine.
This machine has a reversing switch to change the
direction of rotation. Move the reversing switch lever
to the position (DP4700)/the ''FWD'' position
(6402) for clockwise rotation or the
(DP4700) /the ''REV'' position (6402) for counter-
clockwise rotation.
Drilling operation
• Drilling in wood
When drilling in wood, the best results are obtained
with wood drills equipped with a guide screw. The
guide screw makes drilling easier by pulling the bit
into the workpiece.
• Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and ham-
mer at the point to be drilled. Place the point of the
bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be
drilled dry.
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 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.
• 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.
