Optional accessory The hook is useful to hang the tool. Install the hook to the holes on the tool body. Fig.16: 1. Hook 2. Hole

OPERATION

CAUTION: Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your drill bit, decrease the tool performance and shorten the service life of the tool.
CAUTION: Always secure workpieces in a vise or similar hold-down device.
Fig.17
Hold the tool firmly and place the point of the driver bit/ socket 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: If you use a spare battery to continue the operation, rest the tool at least 15 min.
NOTICE: Use the proper bit for the head of the screw/bolt that you wish to use.
NOTICE: Hold the tool pointed straight at the screw.
NOTICE: If you tighten the screw for a long time, the screw or the point of the driver bit may be overstressed, stripped, damaged, etc. Before starting your job, always perform a test operation to determine the proper fastening time for your screw.
NOTICE: If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.
The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1. When the battery cartridge is discharged almost completely, the 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 the 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 use of the universal joint or the socket adapter somewhat reduces the fastening force of the tool. Compensate by fastening for a longer period of time.

5. The type of materials to be fastened, the manner of holding the tool and the tool speed will affect the torque.

6. Operating the tool at a low speed will cause a reduction in the fastening torque.

Fastening torque and torque level
NOTE: This reference value is measured by the measurement conditions specified by Makita.
NOTE: The actual value may differ according to the circumstances of the fasteners, materials, and fastening method. Perform a test drive before actual work.

MAINTENANCE
