• After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
Hook (Fig. 11)
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
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.
(Fig. 12, 13 & 14)
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.
NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• When fastening screw M8 or smaller, choose a proper
hammer force, and carefully adjust pressure on the
switch trigger so that the screw is not damaged.
• Hold the tool pointed straight at the screw.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspec-
tion or maintenance except for the following troubleshooting related to the light.
Cleaning
From time to time wipe off the outside (tool body) of the tool using a cloth dampened in soapy water.
CAUTION:
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
Troubleshooting
Trouble
Light status/LED indicator status/tool status
LED indicator for empty signal for remaining
battery capacity lights up.
Light flickers once per second.
The tool
stops during
operation.
Light flickers five times per second.
Switch trigger has been pulled continuously
for more than 130 seconds.
Other Symptoms
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita replacement parts.
• If the hammering force is too strong 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 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 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.
Steps to be taken
Remaining battery capacity level is low. Charge the
battery cartridge.
When the LED indicator still lights up even after
charging the battery cartridge, the tool temperature is
high. Cool down it fully. The tool restarts after its
temperature becomes low.
When the status is still unchanged, stop using and
have the tool repaired by a Makita local service
center.
The tool temperature is high. Cool down it fully. The
tool restarts after its temperature becomes low.
Use the tool with the motor not locked. (When the
tool has stopped due to the motor locking, withdraw
the battery cartridge one time and then insert it again
or release the switch trigger for more than
60 seconds to restart the tool.)
If the motor still remains locked, stop using and have
the tool repaired by a Makita local service center.
Release the switch trigger.
Stop using and have the tool repaired by a Makita
local service center.
