j.
Always assume that the tool con-
tains fasteners. Do not point the tool
toward yourself or anyone whether it
contains fasteners or not.
e. Store the tool when it is idle out of
reach of children and other un-
trained persons. A tool is dangerous
in the hands of untrained users.
WARNING – Do not fire fastener on f.
top of another fastener. This is able
to cause the fastener to be deflected
and hit someone, or cause the tool to
react and result in a risk of injury to
persons.
