WARNING
!
Each part of the engine is still highly heated immediately
after the engine is stopped. Do not attempt to drain cooling
water or remove the filter element cup.
!
High pressure is generated inside the engine fuel piping,
while the engine is running. Wait for more than 30 seconds
after the engine stop for the engine to sufficiently cool down.
Then start with draining cooling water or removing the filter
element cup.
Do not bring fire close.
Check water separator, drain water and sediment.
1. Open the engine side cover on the right side of the machine.
The water separator forms one unit with the fuel pre-filter,
and is at the bottom.
2. It is possible to judge the condition of water and sediment
through transparent cap (3). If water or sediment is accumu-
lated, set a container under drain hose (4) to collect the dis-
charged water.
3. Loosen plug (2) and drain the water.
4. Tighten plug (2) as soon as fuel starts to be discharged from
drain hose (4).
Tightening torque: 0.2 - 0.45 Nm
5. On this machine, sensor (5) is installed to detect if water is
accumulated at the bottom of the fuel pre-filter.
If water separator caution lamp (6) on the machine monitor
lights up, carry out the above Steps 1 - 4 to drain the water.
