Check / Clean Water Separator
WARNING!
• The water separator pot has fuel (diesel oil)
inside. Be extremely careful of fire such as
cigarette when cleaning the water separator
pot.
• If the fuel spills when the water separator
pot is removed, thoroughly wipe it off.
CAUTION:
• Water or dust accumulated inside the water
separator pot will cause engine failure.
Check inside the pot and remove any water
or dust accumulated inside.
• If water remains in the water separator pot, it
is assumed that much water is also mixed in
the fuel tank. See "Drain Contaminant
Water/Deposits in Fuel Tank" on page 5-38
and eliminate water and dust mixed into the
fuel tank.
1. Stop the machine at levelled location.
2. See "OUTRIGGER SETTING" on page 4-36
and rotate the "Outrigger (1)" and "Outrigger
(2)" outrigger rotaries outward.
3. Open the access hatch in the right-hand
machinery cover.
4. Check the water separator pot (1) for any
water or dust in the pot and verify if the red
float (2) in the pot has not come up from the
bottom.
The red float (2) in the pot (1) coming up
indicates that the water has mixed in.
