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.
• If the hammering force is too strong, or 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 over-
stressed, stripped, damaged, etc. Before starting your
job, always perform a test operation to determine the
proper fastening time for your 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.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
Troubleshooting
Trouble
Flickers twice per second.
The tool temperature is high.
Flickers three times per second.
(LED indicator for empty signal
for remaining battery capacity
also flickers.)
The tool stops
Flickers five times per second.
during operation.
Flickers once per second.
Not flickers.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
Light status
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
The tool temperature is high. Cool down it fully.
The tool restarts after its temperature becomes low.
Remaining battery capacity level is low. Charge the battery
cartridge. When the LED indicator still flickers even after
charging the battery cartridge, stop using and have the tool
repaired by a Makita local service center.
Use the tool with the motor not locked. If the motor remains
locked, stop using and have the tool repaired by a Makita
local service center.
Stop using and have the tool repaired by a Makita local
service center.
The tool stops when continuing to pull the switch trigger for
more than approximately 2 minutes.
Release the switch trigger.
