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.
