Hydraulic Fluid Fill/Bleed

HYDRAULIC FLUID FILL/BLEED





NOTE: The hydraulic system uses ARAL VITAMOL ZH-M fluid. When replacing components or topping off system due to leak, make sure to use only approved fluid.

Whenever a system is opened, the level of the fluid must be maintained. If some leaks out or a part is replaced, then it must be replaced. The pump is self bleeding by running it up and down.

Perform the following in order to get the proper level of fluid in the pump reservoir:

1. Make sure that the system is sealed.
2. Remove the hydraulic pump/motor from its mounting location but don't remove any lines . Motor/Pump-Hydraulic - Assembly
3. Remove the pump bracket and jute/cover that surrounds the pump.
4. The fill hole to the reservoir is on the left side of the pump as it is mounted. You must turn the pump/motor on its right end to allow it to be filled. Don't overfill or damage to pump/motor may occur. The proper fill level of the fluid is up to the fill plug when the pump/motor is horizontal.

NOTE: As the lost fluid is replaced in each component, the reservoir will drain. Check the reservoir often while running the top up and down.

5. Fill reservoir up enough to allow it to run and fill up whatever was replaced or leaked out.
6. Operate the power top up and down and check/replace fluid until proper level is reached with the pump in the horizontal position.
7. Repeat STEP 6 as necessary to reach proper fluid level.
8. After fluid is at proper level, install bracket on pump/motor.
9. Install the pump/motor . Motor/Pump-Hydraulic - Assembly
