6.7 Checking <strong>Engine</strong> Speed<br />
See Graphic: wc_gr001625, wc_gr001634, and wc_gr002441<br />
Using either a photo (strobe) tachometer, a frequency meter (60Hz =<br />
1800 rpm; 50Hz = 1500 rpm), or a vibration tachometer such as a<br />
Sirometer (a) (<strong>Wacker</strong> P/N 0053397), check engine rpm. Refer to the<br />
instrument instructions. If necessary, adjust engine rpm using<br />
adjusting screw [(b) <strong>Lombardini</strong> engines, (c) CAT engines]. No load<br />
engine speed should be 1850 rpm for 60Hz and 1550 rpm for 50Hz<br />
models.<br />
NOTICE: Do not adjust the engine speed to be higher than that listed<br />
above. The electrical components are frequency sensitive. Running at<br />
higher speeds will lead to component damage.<br />
Also check the condition of the engine air, fuel, and oil filters. Change<br />
the filters if necessary. See maintenance section.<br />
