NOTICES WHEN USING 2-WHEEL DRUM TESTER

1. When using a 2-wheel drum tester such as a speedometer tester, a combination tester of speedometer and brake, chassis dynamometer or else, always turn the TRAC system off via the TRAC OFF switch before measurement.

NOTE: TRAC system OFF condition can be confirmed by the indication, "TRAC OFF" of the warning light in the combination meter.
