6 cylinder engines, it is necessary to

make the proper adjustments to adapt

this tachometer to your cylinder range.

The hole location is shown for 3

" and 3

" sizes. The 5" size

has a smaller access hole located in the upper left-hand portion

of the case. Remove the plastic plug covering the access hole.

use a small screwdriver or an unwound paper clip to change the

switch settings. Move each of the two switches to the proper

cylinder selection according to the diagram illustrated on the

right. Reinstall the plastic plug/cap into the access hole.

It is normal for the pointer to leave zero. When power

is applied, the pointer will move to the correct position.
