Installing Hook; Operation; Screwdriving Operation - Makita DDF489Z Instruction Manual

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/
drill bit
Optional accessory
► Fig.9: 1. Sleeve 2. Close 3. Open
Turn the sleeve counterclockwise to open the chuck
jaws. Place the driver bit/drill bit in the chuck as far
as it will go. Turn the sleeve clockwise to close the
chuck. To remove the driver bit/drill bit, turn the sleeve
counterclockwise.
Installing side grip (auxiliary handle)
Optional accessory
► Fig.10: 1. Side grip 2. Protrusion 3. Groove 4. Arm
When operating in the heavier load, using the side grip
enables to hold the tool more stably.
Install the side grip so that the protrusions on the arm fit
in the grooves on the tool barrel. Turn the grip clockwise
to secure it.
Depending the operations, you can install the side grip
either right or left side of the tool.

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.
► Fig.11: 1. Groove 2. Hook 3. Screw
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
holders. Driver bits 45 mm-long 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 bottom of the battery cartridge to
control the twisting action.
► Fig.14
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.
