5. Use an optional adjusting grip to adjust the fastening
torque. Insert the pin of the adjusting grip into the hole
in the front of the tool. And then, turn the adjusting grip
clockwise to set a greater fastening torque, and coun-
terclockwise 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 fasten-
ing 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 bat-
tery cartridge is removed before carrying out any work
on the tool.
Installing or removing driver bit or socket bit
(Fig. 9 & 10)
Use only the driver bit or socket bit shown in the figure.
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.
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
Screwdriving operation (Fig. 11)
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°. 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 flickers in
red and green alternatively).
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 capac-
ity 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 bat-
tery 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.
Replacing carbon brushes (Fig. 12 & 13)
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
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.
