8.

Continue to draw the vacuum until the gauge reaches 28 inches
of vacuum. The gauge may not reach 28 inches in high altitude
locations; refer to the vacuum specifications based on the alti-
tude above sea level.

9.

When the vacuum gauge has reached the specified amount, disconnect the air hose and wait 20 seconds
to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the
system and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for any leaks. 

10. Place the coolant container (with the refill hose inserted) at the same level as the top of the radiator. Then

open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling
system is full when the vacuum gauge reads zero.

CAUTION:

Do not allow the coolant container to get too low when filling, to avoid air from being drawn into
the cooling system. 

11. Remove the Tool from the radiator neck opening.

12. Fill the cooling system reservoir tank to the specified level. Run the engine to warm up the cooling system

and top up the system as necessary before installing the radiator cap.

FLUSHING COOLING SYSTEM

1.

Fill the radiator from the filler cap above the radiator upper hose and reservoir tank, with water and rein-
stall the filler cap above the radiator upper hose. 

2.

Run the engine until it reaches normal operating temperature.

3.

Press the engine accelerator two or three times under no-load.

4.

Stop the engine and wait until it cools down.

5.

Drain the water.

6.

Repeat steps 1 through 5 until clear water begins to drain from the radiator.

Checking Fuel Lines

ELS000XA

Inspect fuel lines and tank for improper attachment, leaks, cracks,
damage, chafing and deterioration. If necessary, repair or replace. 

Changing Fuel Filter

ELS000XB

WARNING:

Before removing fuel filter, release fuel pressure from fuel line.

2.

Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode to release fuel pressure to zero.

3.

After engine stalls, crank engine two or three times to make sure that fuel pressure is released.

4.

Turn ignition switch “OFF”.

5.

Remove the fuel filter shield.

6.

Loosen fuel hose clamps.

7.

Replace fuel filter.

●

Use a high-pressure type fuel filter. Do not use a synthetic
resinous fuel filter.

8.

Tighten fuel hose clamps.

CAUTION:

Tighten high-pressure rubber hose clamp so that clamp
end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that the screw does not contact adjacent parts.

1.

Remove fuel pump fuse.
For correct fuse location, refer to label on fuse block cover.

2.

Start engine.

3.

After engine stalls, crank engine two or three times to make sure
that fuel pressure is released.

4.

Turn ignition switch “OFF” and install fuel pump fuse.
