TOOL OPERATION

Purging

The combustion chamber drops when the tool is

lifted from the work surface and the trigger is re-

leased. This opens the seal between the combustion

chamber and cylinder head O-Ring (W) and sleeve

O-Ring (X).

The fan is now able to circulate fresh air into the

combustion chamber, cooling the sleeve (Y) and

purging any remaining exhaust gases from the tool

through ports (Z).
