Drilling Operation - Makita DDF486RTJ Betriebsanleitung

Installing hook
WARNING:
Use the hanging/mounting parts
for their intended purposes only, e.g., hanging the
tool on a tool belt between jobs or work intervals.
WARNING:
Be careful not to overload the
hook as too much force or irregular overburden
may cause damages to the tool resulting in per-
sonal injury.
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
CAUTION:
Make sure to hang the tool
securely before releasing your hold. Insufficient
or unbalanced hooking may cause falling off and you
may be injured.

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.
Using hole
WARNING:
Never use the hanging hole for
unintended purpose, for instance, tethering the
tool at high location. Bearing stress in a heavily
loaded hole may cause damages to the hole, result-
ing in injuries to you or people around or below you.
► Fig.12: 1. Hanging hole
Use the hanging hole at the bottom rear of the tool to
hang the tool on a wall using a hanging cord or similar
strings.
Installing driver bit holder
Optional accessory
► Fig.13: 1. Driver bit holder 2. Driver bit
Fit the driver 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 driver bit hold-
ers. Driver bits 45 mm-long (1-3/4") can be kept there.
OPERATION
CAUTION:
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 handle to control the twisting action.

NOTICE:
Do not cover vents, or it may cause over-
heating and damage to the tool.

Screwdriving operation
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
First, turn the adjusting ring so that the arrow on the tool
body points to the proper fastening torque level (1 - 21).
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.
NOTE: When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.

Drilling operation

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 drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill 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.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
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.
First, turn the adjusting ring so that the arrow 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 drill bit into
the workpiece.
Drilling in metal
To prevent the drill 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
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
