WARNING
HAZARDOUS ROTATING EQUIPMENT.
Do not reach over the pulley to operate the
START or STOP buttons. Walk around to
the front of calibrator. Beware of loose
clothing as it may become entangled in
rotating equipment.

9. Press the START button.
10. Press the end of the tachometer shaft against
the back end of the camshaft and read RPM.
Keep the tachometer aligned with the cam-

shaft is oil-free. Oil on the camshaft will cause
the tachometer shaft to slip. Inaccurate read-
ings will result.
11. Record the reading.
12. Press the STOP button.
13. If speed is 2000 RPM ± 5 RPM, skip to step 15.
14. If speed is not 2000 RPM ± 5 RPM:
a. Make sure the pulley and motor match line
frequency (see specifications on nameplate
inside left side door).
b. Operate the calibrator without an injector
installed and without push rod adapter.
c. Recheck speed with tachometer.
d. If problems still exist, check for drive shaft,
pump shaft or motor shaft binding and
replace necessary parts.
15. If speed is normal, turn the circuit breaker
OFF.
