Notes:
1. Be sure the engine oil, engine oil
storage containers, and engine oil
filling equipment are free of
sediments and water.
2. Change the engine oil after the first
50 hours of operation and then at
every 250 hours thereafter.
3. Select the oil viscosity based on the
ambient temperature where the
engine is being operated. See the
SAE Service Grade Viscosity Chart
(Figure 2).
4. Yanmar does not recommend the
use of engine oil “additives.”

Requirements:
The engine oil must be changed when the
Total Base Number (TBN) has been
reduced to 2.0. TBN (mgKOH/g) test
method; JIS K-2501-5.2-2 (HCI), ASTM
D4739 (HCI).
CAUTION
• Only use the engine oil
specified. Other engine oils
may affect warranty coverage,
cause internal engine
components to seize, or
shorten engine life.
• Prevent dirt and debris from
contaminating engine oil.
Carefully clean the oil
cap / dipstick and the
surrounding area before you
remove the cap.
• NEVER mix different types of
engine oil. This may adversely
affect the lubricating
properties of the engine oil.
• NEVER overfill. Overfilling may
result in white exhaust smoke,
engine overspeed or internal
damage.
