Check Water Separator
Drain water --- every 8 hours (before starting
operation)
Water separator (1) is a device designed to separate water from
the fuel. There is a float inside the case which buoys when
water accumulates.
When the float rises to the water draining level, drain water.
Drain Procedures
1. Park the machine following the same procedures as
described on page 7-7 for preparation for inspection and
maintenance.
2. Place a 0.5 liters or larger capacity container under drain
plug (3) to collect the drained water.
3. Close cock (2) at upper part of water separator (1).
Loosen drain plug (3) at lower part of water separator (1)
to drain water. If it is difficult to drain water, loosen air
bleed plug (4) counterclockwise 2 to 3 turns.
4. After draining water, securely tighten drain plug (3) and
plug (4).
5. Open cock (2).
IMPORTANT: After draining water from the water
separator, bleed air from the fuel supply system.
Bleed Air from Fuel System
Air in the fuel system will cause the engine to start hard
and/or run roughly. Be sure to bleed air from the system
after replacing the fuel filter or running the fuel tank dry.
Automatic bleeding deveice is provided on this machine.
1. Confirm that the fuel level is more than one-half of
the tank capacity. If the fuel level is lower, automatic
bleeding device will not operate. Add fuel.
2. Turn the key switch ON and hold for 10 to 15 seconds.
3. Start the engine and check the fuel system for fuel leaks.
