Operation - Makita DDF470 Bedienungsanleitung

Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
The following shows the rough guide of the relationship
between the screw size and graduation.

ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before carrying out
any work on the tool.
Installing or removing driver bit or drill bit
Fig.9
Turn the sleeve counterclockwise to open the chuck
jaws. Place the bit in the chuck as far as it will go. Turn
the sleeve clockwise to tighten the chuck.
To remove the bit, turn the sleeve counterclockwise.
Hook
Fig.10
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.
Installing bit holder (Optional accessory)
Fig.11
Fit the bit holder into the protrusion at the tool foot on
either right or left side and secure it with a screw.
When not using the driver bit, keep it in the bit holders.
Bits 45 mm-long can be kept there.

OPERATION

CAUTION:
Always insert the battery cartridge all the way until
•
it locks in place. If you can see the red part on the
upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If
not, it may accidentally fall out of the tool, causing
injury to you or someone around you.
When the speed comes down extremely, reduce
•
the load or stop the tool to avoid the tool damage.

Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to
control the twisting action.
Screwdriving operation
CAUTION:
Adjust the adjusting ring to the proper torque level
•
for your work.
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.
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 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.
