Safety Precautions
CAUTION
Coolant Hazard!
• Wear eye protection
and rubber gloves
when you handle long
life or extended life
engine coolant. If
contact with the eyes
or skin should occur,
flush eyes and wash
immediately with
clean water.
• Failure to comply may result in minor or
moderate injury.
CAUTION
Flying Object Hazard!
• Always wear eye protection when
servicing the engine and when
using compressed air or high-
pressure water. Dust, flying
debris, compressed air,
pressurized water or steam may
injure your eyes.
• Failure to comply may result in minor or
moderate injury.
CAUTION
Be sure to secure the engine solidly to prevent
injury or damage to parts due to the engine
falling during work on the engine.
CAUTION
Pinch Hazard!
Carefully rotate the alternator
toward the cylinder block while
loosening the V-belt. Failure to
comply may result in minor or
moderate injury.
CAUTION
If any oil pump component clearance exceeds
its limit, the oil pump must be replaced as an
assembly.
CAUTION
To refuel the engine oil, refuel slowly after
removing the dipstick and both caps. If you
refuel rapidly, the oil intrusion to the intake
occurs through the PCV valve of the valve
cover. It will result in an oil hammer at engine
start, which may cause damage to the engine.
NOTICE
• Only use diesel fuels recommended by YANMAR
for the best engine performance, to prevent
engine damage and to comply with EPA/ARB
warranty requirements.
• Only use clean diesel fuel.
• Never remove the primary strainer (if equipped)
from the fuel tank filler port. If removed, dirt and
debris could get into the fuel system causing it to
clog.
NOTICE
Never attempt to adjust the low or high idle speed
limit screw. This may impair the safety and
performance of the machine and shorten its life. If
adjustment is ever required, contact your
authorized YANMAR industrial engine dealer or
distributor.
NOTICE
If any problem is noted during the visual check, the
necessary corrective action should be taken before
you operate the engine.
NOTICE
Never hold the key in the START position for longer
than 15 seconds or the starter motor will overheat.
