Maintenance; Optional Accessories - Makita DHP470 Bedienungsanleitung

Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.

After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Screwdriving operation
First, turn the action mode changing ring so that the
arrow on the tool body points to the
the adjusting ring to the proper torque level for your
work. Then proceed as follows.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
CAUTION:
Make sure that the driver bit is inserted straight in
•
the screw head, or the screw and/or bit may be
damaged.
NOTE:
When driving wood screw, predrill a pilot hole 2/3
•
the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
Drilling operation
First, turn the adjusting ring so that the pointer points to
the marking. Then proceed as follows.
CAUTION:
Pressing excessively on the tool will not speed up
•
the drilling. In fact, this excessive pressure will
only serve to damage the tip of your bit, decrease
the tool performance and shorten the service life
of the tool.
There is a tremendous force exerted on the tool/bit
•
at the time of hole break through. 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 in order 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 with a
•
similar hold-down device.
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
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 to make a
hole, make an indentation with a center-punch and
hammer 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.
