Calibration
IMPORTANT: This tachometer is factory calibrated to
operate on 8 cylinder engines. For 4 or
6 cylinder engines, it is necessary to
make the proper adjustments to adapt
this tachometer to your cylinder range.
NOTE: Calibration changes do not apply to the Jr. Dragster
tachometer. The Jr. Dragster tachometer is calibrated
to operate only on Briggs & Stratton engines.

To change the tachometer calibration, access to the inner case
is necessary. Remove the two acorn nuts as shown in figure A
and carefully slide the cup of the tachometer back in order to
access the inner case. Locate the switch access hole on the inner
case. Remove twist-lock light socket to access the calibration
switches. (See light replacement) 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.
NOTE: This tachometer has an air core meter. With power off,
It is normal for the pointer to leave zero. When power
is applied, the pointer will move to the correct position.

The special design of the tachometer base allows for a variety of mounting possibilities.
Loosening the hex screws at the mounting base allows the tachometer to be rotated in
the strap. Also, this design allows the tachometer face to be angled forward or backward
for better viewing. Attach the base using screws provided or some other fasteners.
See figure C. Rotate twist-lock socket counterclockwise using needle nose pliers and remove.
Replace old bulb with GE 194 bulb.
