General information
General Information
As time passes after purchasing an engine, each of the
engines parts age and initial engine performance cannot be
maintained.
Regular inspection and replacement according to the recom-
mended regular inspection table allows you to maintain an
engine with the optimum conditions and best performance
for a long period and prevent unexpected accidents in
advance.
Users are responsible for the proper operation and mainte-
nance of engines. Engines should be inspected and replaced
by officially-certified technicians in a workspace with the
specified tools and facilities. Observe the following instruc-
tions to perform inspections.
1. Perform inspections on a flat floor without a slope.
2. Excluding extreme circumstances, only perform inspec-
tion while the engine is stopped.
3. Disconnect the '-' terminal of the battery before
performing an inspection.
4. Perform inspection in a well ventilated space.
5. Use a wooden prop or lift when working under the engine.
Routine Inspection
Routine inspection is an inspection performed by an engine
operator before operating the engine. It should be performed
to protect operator's safety, as well as the engine.
The following is a minimal check list.
1. Check whether the engine smoothly starts and the levels
of fuel, oil, and coolant are within the normal range.
2. Check if any discharged emissions are colored and if the
exhaust contains toxic gas elements.
3. Check whether abnormal noise occurs after starting an
engine or not.
4. Check whether oil or water is leaking.
DANGER
• Wait until the engine is sufficiently cooled before
starting inspection after operating the engine.
Otherwise, you may be burned.
• You may be poisoned by the emission when starting
an engine in a closed space. Perform inspection at
the well-ventilate space.
• Unless absolutely compelled, do not perform
inspection under an engine.
• Do not be close to fire when inspecting an engine.
Fuel, oil, or batteries may generate gas, causing fire.
• If inspecting the engine while it is running, do not
wear accessories such as necklaces, rings, watches
or gloves. Such accessories may become stuck in
rotating parts while the engine is running and may
cause serious bodily injury.
CAUTION
• Incorrect inspection methods may cause of engine
faults.
• Cleaning an engine with liquids such as water or
wax may cause breakdown of electrical parts.
• Be careful when handling batteries, cables, and
electrical wirings because current flows through
those parts.
• Do not put heavy things or apply excessive force or
impact on the fuel-related units.
• Make sure that you connect the battery terminal ('+'
and '-') to the right terminal. Connecting the '+' and
'-' terminals to the wrong terminal may cause
damage to the electrical unit parts and fire.
