BEFORE YOU OPERATE

DAILY CHECKS

Before you start for the day, make sure the
Yanmar engine is in good operating
condition. CAUTION! It is important to
perform daily checks as listed in this
Operation Manual. Periodic
maintenance prevents unexpected
downtime, reduces the number of
accidents due to poor engine
performance and helps extend the life of
the engine. Make sure you check the
following items:

Visual Checks

1. Check for engine oil leaks.
2. Check for fuel leaks.
3. Check for engine coolant leaks.
4. Check for damaged or missing parts.
5. Check for loose, missing or damaged
fasteners.
6. Check the electrical harnesses for
cracks, abrasions, and damaged or
corroded connectors.
7. Check hoses for cracks, abrasions and
damaged, loose or corroded clamps.
8. Check the fuel filter / water separator for
presence of water and contaminants. If
you find any water or contaminants,
drain the fuel filter / water separator.
See Draining Fuel Filter / Water
Separator on page 62. If you have to
drain the fuel filter / water separator
frequently, drain the fuel tank and check
for water in your fuel supply. See
Draining Water From the Fuel Tank on
page 61.
CAUTION! If any problem is noted
during the visual check, the necessary
corrective action must be taken before
you operate the engine.
