Inspection

Oil Pressure Switch
1. Check the continuity between the terminal and the body with an ohmmeter.
If there is no continuity, replace the oil pressure switch.




2. Check the continuity between the terminal and the body when the fine wire is pushed. If there is continuity even when the fine wire is pushed, replace the switch.
3. If there is no continuity when a 50kpa (7psi) is applied through the oil hole, the switch is operating properly.
Check for air leakage. If air leaks, the diaphragm is broken. Replace it.





Selection Of Engine Oil
Recommended API classification : Above SJ or SL
Recommended SAE viscosity grades : 5W-20
If 5W-20 engine oil is not available, 5W-30 or secondary recommanded engine oil for corresponding temperature range can be used.





NOTE:
For best performance and maximum protection of all types of operation, select only those lubricants which :
- Satisfy the requirement of the API classification.
- Have proper SAE grade number for expected ambient temperature range.
Lubricants that do not have both an SAE grade number and API service classification on the container should not be used.

Engine Oil
1. Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace the oil.
2. Check engine oil level.
After warming up the engine and then 5 minutes after the engine stops, oil level should be between the "L" and "F" marks on the dipstick.
If low, check for leakage and add oil up to the "F" mark.

NOTE:
Do not fill with engine oil above the "F" mark.
