SAFETY PRECAUTIONS
HOT SURFACES AND FLUIDS
• There is always a risk of burns when working
with a hot engine. Be aware of hot parts like
the turbocharger system, the exhaust system,
hot coolant hoses, etc. Wait until the engine
is fully cool to do inspection and maintenance.
REFUELING
• Refuel only after the engine completely stops.
• Use only the recommended fuel. The wrong
grade of fuel can cause operating problems,
can cause the engine to stop and can cause
engine damage.
• Pay special attention to safe practices when
refueling.
PAINT DAMAGE
• Damage of the engine or parts paint during
maintenance and inspection can cause
corrosion. Any damage must be repainted
after inspection and maintenance.
WELDING ON ENGINE
• Welding directly on the engine block can
cause damage to the engine control systems.
The ECU and related electronic devices must
be disconnected and removed if unavoidable
welding is needed.
.
• Read and understand this operator’s manual as
well as other information supplied by Hyundai
SeasAll for safe use of these products. Be sure
to check your engine regularly.
• Do not use the engine for a purpose other than
what is intended by Hyundai SeasAll. Do not
modify the performance of the supp-lied engine
without the express permission of Hyundai
SeasAll. This can be dangerous, can shorten
the life of your engine and in-validate your
warranty.
• Original and genuine parts supplied from
Hyundai SeasAll must be used for inspections
and maintenance. Hyundai SeasAll does not
guarantee any damage caused by the use of
imitation parts.
• Engine inspection and maintenance should be
carried out by properly trained and factory
approved service engineers.
• The engine should be inspected if the electronic
engine control unit shuts down the engine.

first 10 hours except during the engine initial
Break-In Procedure. During the next 10 hours,
occasional operating at full throttle (5 minutes
at a time maximum) is permissible.
• AVOID full throttle accelerations from neutral
position.
• DO NOT operate at all full throttle until engine
