Operating Procedure
1. Attach a bit to the driver. (See "Attaching a Bit" below)
• If using model BL-3000, remove the torque adjustment nut
cover before attaching a bit.
2. Set the driver to clockwise or counter-clockwise rotation as
desired, then push the switch lever to check that the driver
turns in the correct direction. After checking, be sure the
switch is left on the clockwise setting.
Caution: Always turn the power off before reversing the
rotation direction setting.
3. Make the desired torque adjustment setting. (See "Torque
Adjustment" below.)
4. Begin fastening by fitting the end of the bit to the head of a
screw to be tightened and pulling the switch lever.
• In push-to-start mode, the driver automatically goes on
when pressure is applied to the bit end.
5. The clutch will immediately stop rotation when the preset
torque level is reached. At this point, raise the driver from
the screw and release the switch lever. Repeat this cycle
for each tightening operation.
• In push-to-start mode, do not raise the driver from the
screw head until rotation has stopped.
6. Set rotation direction to counterclockwise to loosen a
screw. Very tightly fastened screws can be loosened by
repeatedly applying the driver to the screw to obtain short
bursts of rotation force.
■
Attaching a Bit
Be sure to either turn the power
switch off or disconnect the power
cord before attempting to change
bits. Failure to do so could be
especially dangerous if the driver is
set to push-to-start mode. In either
case, unexpected start up of the
driver could result in injury.
If using model BL-3000, BL-5000 or BL-
7000, raise the joint shaft collar at the
bottom of the tool, then insert the bit.
• As for BL-2000, press the Joint-shaft
collar towards inside of the screwdriver
and insert the bit.
• If using model BL-3000, push the joint
shaft collar into the tool to attach the bit.
Then pull on it to be sure it is properly
attached.
