Adjusting the fastening torque
Fig.6
When you wish to drive machine screws, wood screws,
hex bolts, etc. with the predetermined torque, adjust the
fastening torque as follows.
1. First remove the battery cartridge from the tool.
2. Loosen and remove the screw that secures ring.
3. Rotate the ring in the front of the tool by hand so
that a hole can be seen below the ring.
4. Place the battery cartridge in place and pull the
switch trigger. Release it so that the adjust ring
rotates and the hole becomes visible as illustrated.
And then remove the battery cartridge.
Fig.7
5. Use an optional adjust grip to adjust the fastening
torque. Insert the pin of the adjust grip into the hole in
the front of the tool. And then, turn the adjust grip
clockwise to set a greater fastening torque, and
counterclockwise to set a smaller fastening torque.
6. Align the yellow line with your desired number on
the fastening torque scale.
7. Insert the battery cartridge and be sure that a
fastening torque has been set up by using a
fastening torque tester.
8. Rotate the ring in front of the tool and then tighten
the screw to secure the ring.
NOTE:
Numbers on the fastening torque scale is a
•
guideline to set up your desired fastening torque.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before carrying out
any work on the tool.
Installing or removing driver bit or socket bit
Fig.8
Use only bit or socket bit that has inserting portion shown
in the figure.
For tool with shallow bit hole: A=12mm, B=9mm
For tool with deep bit hole: A=17mm, B=14mm
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.
Fig.9
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.

OPERATION

Fig.10
Place the point of the driver bit in the screw head and
apply pressure to the tool. Then switch the tool on. When
the clutch cuts in, the motor will stop automatically. Then
release the switch trigger.
NOTE:
Make sure that the driver bit is inserted straight in
•
the screw head, or the screw and/or bit may be
damaged.
Limits of fastening capacity
Use the tool within the range of the revolution angle up to
360 ﾟ. If you use the tool beyond the upper limit of this
range, the clutch does not work. And the tool cannot
deliver enough fastening torque (LED indicator blinks in
purple slowly or lights up in purple).
NOTE:
The revolution angle means the angle which a
•
screw/bolt revolves when the tool attains to 100%
from 50% of desired torque.
Use of a low temperature conditioned battery
•
cartridge may sometimes give warning for battery
cartridge capacity by warning lamp and beeper
which makes the tool stop immediately. In this case,
the fastening capacity may be inferior to the
specification on this manual even if a charged
battery cartridge is used.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
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.
