middle of gauge.
1. See “M/R F/C MNT” in “Data monitor” mode.
2. Run engine at about 2,000 rpm for about 2 minutes under no-
load.
3. Maintaining engine at 2,000 rpm under no-load (engine is

cold.
●
Adjust if belt deflection exceeds the limit or if belt ten-
sion is not within specifications.
●
Turn crankshaft two revolutions and recheck drive belt
deflection or tension.
