II. INSPECTION AND ADJUSTMENT
1. INSPECTION OF ENGINE OIL
• Draw out the level gauge (dip stick) and wipe
the end clean. Then insert and draw out it again.
Check to see if the level is between the upper
and lower limits. If the level is low, refill oil
through the filler to the upper level.
Fig. 3-1
Note:
- When checking oil level, place the machine on
level ground.
- Before checking oil level, stop the engine and
wait three minutes at least.
- When replenishing oil, use the same king of oil
as that in the engine.
• Oil capacities:
E393-G & E383-G: 2.5 litres
• Grades and viscosities of usable oil
Temperatures SAE No. API
°C
classifications
-20 – 30 10w-30 CC or over
below 0 10 ˝
0 – 25 20 ˝
Above 25 30 ˝
• Replacing intervals: After the initial 50 hours
of operation and then after every 100 hours.
Replace the oil filter cartridge after every 300
hours.
a. REPLACEMENT OF OIL FILTER
Remove the oil filter cartridge from the cylinder
block, using a cartridge wrench.
b. INSTALLATION OF OIL FILTER
Inject a small amount of engine oil into the car-
tridge.
Apply engine oil to the O-ring of the cartridge.
Fig. 3-2
Tighten the cartridge by hand until the O-ring
comes into contact with the cylinder block sur-
face and then give it three-fourth turn. After fill-
ing with new oil, operate the engine more than
three minutes. Then check for oil leaks.
