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. 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 possibili-

ties. 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. Gently pry off black plastic access cover to access the twist-in light socket.

Rotate twist-lock socket counterclockwise using needle nose pliers and remove. Replace

old bulb with GE 194 bulb.
