PERIODIC MAINTENANCE
CAUTION
Observe the following environmental
operating conditions to maintain engine
performance and avoid premature
engine wear:
• NEVER run the engine if the ambient
temperature is above +40°C or below -
10°C
If the ambient temperature exceeds
+40°C the engine may overheat and
cause the engine oil to break down.
If the ambient temperature falls
below -10°C rubber components
such as gaskets and seals will
harden causing premature engine
wear and damage.
Contact your authorized Yanmar
industrial engine dealer or
distributor if the engine will be
operated in either temperature
extreme.
• Contact your authorized Yanmar
industrial engine dealer or distributor
if you need to operate the engine at
high altitudes. At high altitudes the
engine will lose power, run rough, and
produce exhaust gases that exceed
the design specifications.
CAUTION
NEVER hold the key in the START
position for longer than 15 seconds or
the starter motor will overheat.

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
exhaust system, to cool slightly before
the engine itself is shut down.
NEVER use an engine starting aid such
as ether. Engine damage will result.
Make sure the engine is installed on a
level surface. If a continuously running
engine is installed at an angle greater
than 20° (in any direction) or if an engine
runs for short periods of time (less than
3 minutes) at an angle greater than 25°
in any direction, engine oil may enter the
combustion chamber causing exessive
engine speed and generate white smoke
and also may occur unsatisfactory oil
pressure. These may cause serious

engine damage.
• NEVER overfill the engine with engine
oil.

• ALWAYS keep the oil level between the
upper and lower lines on the oil
cap / dipstick.
