3-11. PRELIMINARY SERVICING AND ADJUSTING OF EQUIPMENT
After the centrifugal pump assembly has been assembled, set-up, and transported to the operation site, the
following steps must be performed before attempting to start the engine:

difficult starting. This also avoids misfiring and excessive white exhaust smoke.
Make sure the engine is perfectly level. Remove the dipstick cap and fill with Society of Automotive En-
gineers (SAE) service grade oil according to the ambient temperature. (Refer to Table 3-1)
Check the oil level by inserting the dipstick into the oil pan without screwing in the dipstick. (Refer to
