TOOL OPERATION
START and PRE-COMBUSTION
When lower probe (E) is pressed against the work
surface, cage (F) is forced against the spring (G).
Combustion chamber (H) is raised up against
cylinder head (I), and O-Rings (J & M) seal off the
combustion chamber, creating an air tight seal.
This initial movement, pressing the lower probe
against the work surface, causes the fuel cell/meter-
ing valve assembly to pivot. This meters a precise
amount of fuel through the cylinder head and into
the combustion chamber cavity (K).
As the combustion chamber is raised, fan/enable
switch (L) is depressed and the chamber lockout
bar is moved out of the way of the cam. The fan
starts and mixes air with a metered amount of fuel
to provide a combustible mixture.
The chamber lockout bar prevents the trigger from
being activated until the lower probe is pressed
against the work piece, raising the combustion
chamber.
