OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place. If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
CAUTION:
Keep the bolt tips off of the
ground, floor, walkways, etc. to prevent injury
from tripping or falling.
1.
Tighten bolts preliminarily by using a hand wrench.
2.
Hold the tool firmly and place the inner sleeve over
the bolt so that the inner sleeve completely covers the
bolt tip.

NOTICE:
Be careful when fitting the sleeve onto
the bolt tip. Striking the tip can damage it so that it
will no longer fit inside the sleeve properly.
3. Push the tool lightly until the outer sleeve com-
pletely hold the nut. If the outer sleeve fails to hold the
nut, rotate the tool clockwise or counterclockwise while
pushing the tool lightly.
4. Press the trigger-lock button, and then pull the
switch trigger. The outer sleeve rotates to tighten the
nut.

Use bolts with the remaining length
within the range shown in the table above as bolts
with different size have different maximum and
minimum remaining length.

the specified range which may cause the tool
malfunction.
MAINTENANCE
