■ Torque Adjustment
Torque is controlled by the tension on a spring inside the
torque adjustment nut. If set the nut tighter, the output torque
is higher.
• The adjustment torque scale does not give the actual
output torque. Please regard the output torque graph as
an approximate guide.
■ Torque Adjustment Procedure
1. If you have a predetermined torque value, set that value
on the scale using the torque adjustment nut.
• The BL-2000 Electric Screwdriver have 'Double nut
system' (Nut fixing ring and Torque adjusting nut) to avoid
loosening from shock or vibration to the Screwdriver.
● BL-2000
• At first, keep the Nut fixing ring
to fit the scale at which, if you
want to adjust.
• Then turn the Torque adjusting
nut toward the Nut fixing ring.
• Lastly, to avoid the loosening of
the 'Torque adjusting nut fasten
strongly the Nut fixing ring by
holding the 'Torque adjusting
nut'.
● BL-3000
If using model BL-3000, make
the setting by pushing the nut
collar upwards, removing the
t o r q u e a d j u s t m e n t
and turning it so the
point over the nut aligns
with the groove.
● BL-5000, BL-7000
If using model BL-5000 or 7000,
set the torque adjustment nut
using the hex wrench that is
provided.
