3. Disconnect the fuel flow from the fuel tank to the
fuel strainer (fuel-water separator).
4. Loosen the valve plug over the fuel strainer (fuel-
water separator).
5. Place a suitable vessel under the fuel strainer (fuel-
water separator).
6. Remove the drain plug at the bottom to drain the
water and the remaining fuel into the vessel.
7. Remove the fuel strainer (fuel-water separator)
element, replace with a new element and install the
fuel strainer.

B-6 Inspect Air filter of Hydraulic Tank
Keeping the breather cap of hydraulic tank in well-
ventilated condition is vital to normal operation of
hydraulic pump and extending service life. Unqualified
cleanliness or blocked air filter of hydraulic tank may
cause the hydraulic pump to suction improperly, and
continued operation may result in component damage.
The air filter of hydraulic tank should be inspected more
often in hostile operating environment.
NOTICE
Shut off the machine before inspection.
1. Remove the air filter of hdraulic tank.
Figure 5-22
2. Check the air filter element of hydraulic tank.
3. The air should pass through the air filter smoothly.
4. If the air has difficulty in passing through the air
filter, observe the following steps to clean the air
filter.
5. Use neutral solvent to clean the air filter, then blow
dry and repeat the Step 2.
6. Install the air filter back to the hydraulic tank.
B-7 Replace High-Pressure Filter
Element
Replacing high-pressure filter element on a regular
basis is vital to proper machine operation and
extending service life. A dirty or blocked filter could
cause the machine to work improperly, and continued
operation may result in component damage. The high-
pressure filter element should be replaced more often
in hostile operating environment.
BURN HAZARD
Be cautious of hot hydraulic oil.
Bodily contact with hot hydraulic oil
may result in severe burn.
NOTICE
Shut off the machine before inspection.
1. Open the right side cover of turntable, and locate
