The chain counter must be positioned so that the display will be easy to read. It should not be exposed to direct sunlight. Secure the
instrument in place with the bracket provided, tightening the two screws using a cross screwdriver.
For instructions on making electrical connections, see the attached diagram. Drill on the dashboard one hole of 20.5 mm (~13/16") and
4 holes of 2.2 mm (~3/32") to fasten the connector tap.
Put the gasket between the rear part of tap and the dashboard. The rear part must be protected from contact with water or moisture.
For instructions on making electrical connections, see the attached diagram. The wires must have a minimum cross section size
of 1.5 mm². Install a 3 A (ampere) fast safety fuse on the + wire of the battery. Do not use the voltage generated by the engine battery
set to provide power.
The instrument complies with EMC standards (EN55022) and must be positioned at a distance of:
