Operation - Makita DTD157 Instruction Manual

Installing hook
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:
Use the hanging/mounting parts
for their intended purposes only. Using for unin-
tended purpose may cause accident or personal
injury.
► 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.

OPERATION

► Fig.12
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.

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.
NOTICE:
the operation, rest the tool at least 15 min.
NOTE: Use the proper bit for the head of the screw/
bolt that you wish to use.
NOTE: When fastening M8 or smaller screw, choose
a proper impact force and carefully adjust pressure on
3
the switch trigger so that the screw is not damaged.
NOTE: Hold the tool pointed straight at the screw.
NOTE: If the impact force is too strong or you tighten
the screw for a time longer than shown in the figures,
the screw or the point of the driver bit may be over-
stressed, stripped, damaged, etc. Before starting your
job, always perform a test operation to determine the
proper fastening time for your screw.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
4.0
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.
