b.
Open the pressure relief valve so the pressure on the remote throttle is 0 psi. This
should cause the throttle valve (needle block) to open fully and allow all fuel to return to
the fuel tank, thereby not allowing the impact hammer to start.
c.
Simulate starting the impact hammer three times using the hammer trip assembly and
measure the time elapsed from trip disengage until the piston stops bouncing, bottoms
out, and rests fully on the impact block. View the lifting collar on the piston via slot in the
rear of the impact hammer above the trip safety lever. A chalk line can be used to note
the starting point of the lifting collar on the piston.
d.
An impact hammer with adequate compression should take between 15 to 20 seconds
to bottom out. A time of less than ten seconds indicates low compression.
