Evolution GX2, GT2 Ignition System Warning
It has come to our attention that some users are not aware that when using the electronic ignition
if an engine is in the compression position (i.e. the piston is in the upward part of the stroke) any
compressed fumes may ignite causing the propeller to turn.
To prevent this with the Evolution Gasoline GX2, GT2 Ignition System, prior to turning on
power to the ignition (turn on the “Kill-Switch”) one must ensure the piston is NOT ON
COMPRESSION. It should be at Bottom Dead Center (BDC) whenever the ignition is turned on.
Once you are sure the piston is in this position you may then start the ignition system safely.
Bottom Dead Center can be found by rotating the propeller through the compression stroke. (As
you rotate the propeller you will feel it tighten, then suddenly loosen. Once the turn becomes
very easy you have completed the compression stroke.)
As always it is important to use extreme care when near or with engines, fuel and propellers.
Please use caution when working with these components.
