SAFETY
CAUTION
• Only use the engine coolant
specified. Other engine
coolants may affect warranty
coverage, cause an internal
buildup of rust and scale
and / or shorten engine life.
• Prevent dirt and debris from
contaminating engine coolant.
Carefully clean the heat
exchanger cap and the
surrounding area before you
remove the cap.
• NEVER mix different types of
engine coolants. This may
adversely affect the properties
of the engine coolant.
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.

CAUTION
• NEVER overfill the engine with
engine oil.
• ALWAYS keep the oil level
between upper and lower lines
on the oil cap / dipstick.
CAUTION
For maximum engine life,
Yanmar recommends that when
shutting the engine down, you
allow the engine to idle, without
load, for 5 minutes. This will
allow the engine components
that operate at high
temperatures, such as the
turbocharger (if equipped) and
exhaust system, to cool slightly
before the engine itself is shut
down.
CAUTION
NEVER use an engine starting
aid such as ether. Engine
damage will result.
