Checking Steering Pressure

CAUTION

This procedure will require two or more people. The trowel will need to be "run up" while remaining stationary or otherwise held in position. If a "hover" is difficult to maintain the trowel can be butted up to 2 or 3 stakes or to some other none-moveable items.

Z-Clip, Pan

Blade Assembly

1.

Remove the Left Side Access Cover and insert the test

 

pressure gauge (300 to 600 PSI) as shown in Figure

 

48 into the left steering valve's diagnostic quick coupler.

2.

Verify the hydraulic fluid level is correct.

3.

Start the engine and allow the unit to warm up.

4.

Move the throttle lever to FULL engine RPM.

Figure 47. Z-Clip Finisher Pan Installation

1.Lift trowel just enough to slide pan under blades. Lower finisher onto pan with blades assembly adjacent to Z-Clips.

2.Rotate blades into position under Z-Clips. Ensure that the blades are rotated in the direction of travel when the machine is in operation or use the engine to rotate the blades into position.

3.Attach the blade tie-downs to the far side of the Z-Clip brackets with tie-down knobs as shown in Figure 47.

4.Check to make certain that the blade edges are secured under the Z-Clips and the tie-downs are secured completely over the edges of the blade bar before the machine is put back into operation.

Hydraulic Steering Pressure

WARNING

NEVER use your hand to find hydraulic leaks. Use a piece of wood or cardboard. Hydraulic fluid injected into the skin must be treated by a knowledgable physician immediately or severe injury or death can occur.

Many hydraulic problems are a result of low fluid levels. Before checking any other possibilities, make sure the hydraulic fluid is at the proper level in the hydraulic fluid tank.

5. View the guage and record the reading.

Interpreting the Pressure Reading

WARNING

Charge/Steering Pressure must NEVER exceed 300 PSI nor go below 150 PSI. Pressure too high may result in pressure leaks while pressure too low may result in system damage.
