Lubrication & Maintenance/Daily
Daily Pre-starting Checks
Do the following BEFORE STARTING THE ENGINE for the first time each day:
Check engine oil level on dipstick.
IMPORTANT: DO NOT add makeup oil until the oil level is below the crosshatch marks
on the dipstick.
IMPORTANT: DO NOT fill above the top mark on the dipstick. Oil levels anywhere within
crosshatch are considered in the acceptable range.
To change engine oil and oil filter:
Check the fuel filters for water or debris. If filter is fitted with a see-through bowl, drain as
needed based on a daily visual inspection.
IMPORTANT: Drain water into a suitable container and dispose of properly.
a. Loosen drain plugs (A) at bottom of fuel filters or bowls, if equipped, two or
three turns.
b. Loosen air bleed plug (B) two full turns on fuel filter mounting and drain water
from bottom until fuel starts to drain out.
c. When fuel starts to drain out, tighten drain plugs securely.
After draining water from the fuel filters, the filters must be primed by bleeding all air from the
fuel system.
Changing Engine Oil and Replacing Filter
Your engine is equipped with a special oil filter.
NOTE: During break-in, change engine oil and filter for the first time before 100
hours maximum of operation.
After break-in, the oil and filter change interval is 500 hours or every 12 months, whichever
comes first.
NOTE: If diesel fuel with a sulfur content greater than 0.05% (500 ppm) is used,
the oil and filter change interval is reduced.
