Operation; Maintenance - Makita DFL123F Betriebsanleitung

Function
This function works when an
Anti-reset of abnormal drop of the battery
controller voltage occurs for some reason,
and the tool stops.
This function works when the
temperature of the controller
Overheat
goes up very highly, and the
tool stops.
This function works to avoid the
tool's immediate start upon
Operation error of
insertion of battery cartridge
the switch trigger
into the tool with the switch
trigger being pulled.
This indicates the abnormal
Motor malfunction condition of the motor. The tool
does not operate.

Adjusting the fastening torque (Fig. 6 & 7)
When you wish to drive machine screws, wood screws,
hex bolts, etc. with the predetermined torque, adjust the
fastening torque as follows.
1. First remove the battery cartridge from the tool.
2. Loosen the screws securing the light cover.
3. Rotate the ring in the front of the tool by hand so that a
hole can be seen below the ring.
4. Place the battery cartridge in place and pull the switch
trigger. Release it so that the adjust ring rotates and
becomes visible in the hole. And then remove the bat-
tery cartridge.
5. Use an optional adjust grip to adjust the fastening
torque. Insert the pin of the adjust grip into the hole in
the front of the tool. And then, turn the adjust grip
clockwise to set a greater fastening torque, and coun-
terclockwise to set a smaller fastening torque.
6. Align the yellow line with your desired number on the
fastening torque scale.
7. Insert the battery cartridge and be sure that a fasten-
ing torque has been set up by using a fastening torque
tester.
8. Rotate the ring in front of the tool and then tighten the
screw to secure the ring.
NOTE:
• Numbers on the fastening torque scale is a guideline to
set up your desired fastening torque.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Selecting correct socket or screw bit
There are different types of sockets or bits for some mod-
els depending on applications. Choose and install a cor-
rect socket or bit for your application.

Installing or removing socket (Fig. 8)
To install the socket, push it onto the square drive of the
tool with one hand by depressing a pin on the square
drive with another hand until it locks into place. To
remove the socket, simply pull it off depressing the pin on
the square drive.

OPERATION

Hold the tool firmly and place the socket over the bolt or
nut. Then switch the tool on. When the clutch cuts in, the
motor will stop automatically. Then release the switch
trigger.
NOTE:
• Hold the tool with its square drive pointed straight at the
bolt or nut, or the bolt or nut will be damaged.
Limits of fastening capacity (Fig. 9 & 10)
Use the tool within the limits of fastening capacity. If you
use the tool beyond the limits, the clutch does not work.
And the tool cannot deliver enough fastening torque.
NOTE:
• The revolution angle means the angle which a screw /
bolt revolves when the tool attains to 100% from 50%
of desired torque.
• Use of a low temperature conditioned battery cartridge
may sometimes give warning for battery cartridge
capacity by warning lamp and beeper which makes the
tool stop immediately. In this case, the range of fasten-
ing capacity may be inferior to those shown in the
above even if a charged battery cartridge is used.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before attempting to perform
inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centers,
always using Makita replacement parts.
