Maintenance - Makita BTD150 Instruction Manual

Installing or removing bit (Fig. 3)
CAUTION:
Always be sure that the tool is switched off and the battery
cartridge is removed before installing or removing the bit.
Use only the driver bit or socket bit shown in the figure below.
Do not use any other driver bit or socket bit.
To install the bit, pull the sleeve in the direction of the arrow
and insert the bit into the sleeve as far as it will go. Then
release the sleeve to secure the bit.
To remove the bit, pull the sleeve in the direction of the arrow
and pull the bit out firmly.
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.
Switch action (Fig. 4)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the ''OFF'' position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release the
trigger to stop.
Reversing switch action (Fig. 5)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation before the
tool stops may damage the tool.
• When not operating the tool, always set the reversing switch
lever to the neutral position.
This tool has a reversing switch to change the direction of
rotation. Depress the reversing switch lever from the A side for
clockwise rotation or from the B side for counterclockwise
rotation. When the reversing switch lever is in the neutral
position, the switch trigger cannot be pulled.
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.
Screwdriving operation (Fig. 6)
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. Start the tool slowly and
then increase the speed gradually. Release the trigger just as
the screw bottoms out. The proper fastening torque differs
depending upon the kind or size of screws/bolts, the type of
materials to be fastened, etc. Refer to the table for the relation
between fastening time and wood screw size. (Material to be
fastened: Lauan)
NOTE:
• Hold the tool pointed straight at the screw.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece. The
pilot holes should be slightly smaller than the wood screws
in diameter.
• The size of wood screw which can be fastened with this tool
may differ depending upon the type of material to be
fastened. Always perform a test operation to determine the
size of wood screw.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the battery
cartridge is removed before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 7 & 8)
Replace carbon brushes when they are worn down to the limit
mark. Both identical carbon brushes should be replaced at the
same time.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
