Operating Instructions...
CAUTION: Before operating the
nailer check that the nail strip and
fuel cell has been inserted correctly
Step 1:
Insert the battery pack into the nailer as
described earlier in the manual. Position the
contact element against the workpiece. The fan
motor will start, fuel is injected into the
combustion chamber which is mixed with the
air by the fan.
Step 2:
While holding the nailer in position,
squeeze the trigger, the spark plug will ignite the
fuel/air mixture driving the piston down onto the
nail which interns fires it into workpiece. (See fig
17)
Step 3:
Lift the nailer away form the workpiece
then release the trigger which opens the
combustion chamber to allow the fan to blow
the hot gases through the exhaust vents.
