5.15.1.2. Adjustment of Diagonal Blade with Hydraulic Tilt Cylinders (Fig. 5.39).
1. Raise the blade and make several full tilt cycles of the blade.
2. Level the blade.
3. Measure the dimension "A" of the tilt cylinders. If dimension "A" is less than 170 [mm] proceed
as follows:
a)
unscrew plug (2) of the right tilt cylinder and direct the oil flowing out to an adequate
vessel.
b) start the engine and tilt the blade until a small amount of oil will flow out through plug (2).
c) screw in the plug, check the dimension and, if necessary, repeat the above steps until the
right dimension is obtained.
4. If dimension "A" of the tilt cylinders is above 170 [mm], proceed as follows:
a) connect a provisional hose to the quick connector on the mounted equipment valve,
b)
fill the hose with oil,
c)
connect the other end of hose to hole of plug (2) on the right tilt cylinder.
d)
start the engine and make full tilt to the right. Keep the control lever in the full tilt position
until full extension of the right tilt cylinder piston rod.
5. Close the plug.
6. Level the blade.
7. Measure dimension "A" of the tilt cylinders.
8. Repeat steps 4 to 7 until you get dimension "A" on the tilt cylinders equal to 170 [mm]
±
3 [mm].
5.15.1.3. Filling up and Venting the Tilt Cylinders of Diagonal Blade (Fig. 5.39)
The hydraulic circuit has no connection between the piston rod side of the tilt cylinders and the oil
tank and therefore has no capability of self-venting. Whenever balance hose (1) is disconnected,
the cylinders have to be filled with oil and vented as follows:
1. Install the tilt cylinders and connect the hoses.
2. Remove venting plugs (2) located in the upper part of both cylinders.
3. Start the engine and run it at low idle speed. Raise the blade so that its lower tilted end bit is
above the ground.
