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 car-
tridge may sometimes give warning for battery car-
tridge capacity by warning lamp and beeper which
makes the tool stop immediately. In this case, the
range of fastening capacity may be inferior to those
shown in the above even if a charged battery car-
tridge 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.

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.
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.
