2. Start the engine, warm it up for several min-
utes, and then turn it off.
NOTICE
ECA13410
When the engine is cold, the engine oil will
have a higher viscosity, causing the engine
oil pressure to increase. Therefore, be sure
to measure the engine oil pressure after
warming up the engine.
3. Remove:
• Engine oil pressure check point plug “1”
(Bottom of the crankcase)
WARNING
EWA12980
The engine, muffler and engine oil are ex-
tremely hot.
4. Install:
• Oil pressure gauge “1”
• Adapter “2”
5. Measure:
• Engine oil pressure
(at the following conditions)
Out of specification
→
Adjust.
6. Install:
• Engine oil pressure check point plug
TIP
Lubricate the O-ring of the engine oil pressure
check point plug with a thin coat of lithium-soap-
based grease.
