Limits of fastening capacity (Fig. 13, 14, 15, 16,
17, 18)
Use the tool within the limits of fastening capacity. If you
use the tool beyond the limits, the clutch does not work.
And the tool cannot deliver enough fastening torque.
NOTE:
• The revolution angle means the angle which a screw/
bolt revolves when the tool attains to 100% from 51% 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 range of fasten-
ing capacity may be inferior to those shown in the
above 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.
Replacing carbon brushes
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. (Fig. 19)
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. (Fig. 20)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized, always using Makita
replacement parts.
