Makita BTP131 Betriebsanleitung Seite 9

NOTE:
• When the LED display goes off, the tool is turned off to
save the battery power. To check the remaining battery
capacity, slightly pull the switch trigger.
• The LED display goes off approximately one minute
after releasing the switch trigger.
• When the temperature of the tool gets high, the light
flashes once per second for one minute, and then the
LED display goes off. In this case, cool down the tool
before operation.
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.
Installing or removing driver/drill/socket bit
(Fig. 11)
Use only the driver/drill/socket bit shown in the figure. Do
not use any other driver/drill/socket bit.
For tool with shallow bit hole
Use only these type of bit. Follow the
A = 12 mm
procedure (1).
B = 9 mm
(Note) Bit-piece is not necessary.
For tool with deep bit hole
A = 17 mm To install these types of bits, follow the
B = 14 mm procedure (1).
To install these types of bits, follow the
A = 12 mm procedure (2).
B = 9 mm (Note) Bit-piece is necessary for install-
ing the bit.
1. To install the bit, pull the sleeve and insert the bit into
the sleeve as far as it will go. Then release the
sleeve to secure the bit. (Fig. 12)
2. To install the bit, insert the bit-piece and bit into the
sleeve as far as it will go. The bit-piece should be
inserted into the sleeve with its pointed end facing
in. Then release the sleeve to secure the bit. (Fig.
13)
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
CAUTION:
• Do not touch the drill bit shortly after operating as it
gets hot. Replace the drill bit after cooling it down.
NOTE:
• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and the
bit will not be secured. In this case, try re-inserting the
bit according to the instructions above.
• After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
Hook (optional accessory) (Fig. 14)
CAUTION:
• When installing the hook, tighten the screw firmly. Fail-
ure to do so may cause the breakage of the tool or per-
sonal injury.
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 hous-
ing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
OPERATION (Fig. 15)
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place with a little click. If you can see the red
indicator on the upper side of the button, it is not locked
completely. Install it fully until the red indicator cannot
be seen. If not, it may accidentally fall out of the tool,
causing injury to you or someone around you.
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
Impact driver mode "
Screwdriving
Hold the tool firmly and place the point of the driver bit in
the screw head. Apply forward pressure to the tool to the
extent that the bit will not slip off the screw and turn the
tool on to start operation.
Tightening bolts (Fig. 16 & 17)
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between fas-
tening torque and fastening time is shown in the figures.
NOTE:
• When the action mode is set to impact driver mode,
make sure that the tool impacts properly by fastening a
wood screw before operation. If the tool does not work
properly, contact your nearest Makita service center.
• Hold the tool pointed straight at the screw.
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• When fastening screw M8 or smaller, carefully adjust
pressure on the switch trigger so that the screw is not
damaged.
• If you tighten the screw for a time longer than shown in
the figures, the screw or the point of the driver bit may
be overstressed, stripped, damaged, etc. Before start-
ing your job, always perform a test operation to deter-
mine the proper fastening time for your screw.
The fastening torque is affected by a wide variety of fac-
tors including the following. After fastening, always check
the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2. Driver bit or socket bit
Failure to use the correct size driver bit or socket bit
will cause a reduction in the fastening torque.
3. Bolt
• Even though the torque coefficient and the class of
bolt are the same, the proper fastening torque will
differ according to the diameter of bolt.
• Even though the diameters of bolts are the same,
the proper fastening torque will differ according to
the torque coefficient, the class of bolt and the bolt
length.
4. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.
5. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
