HYDRAULIC SYSTEM

Checking Hydraulic Oil Level

                             -IMPORTANT-

correct immediately.

If the oil level is consistently low, check for leaks and

1. Wipe dirt and contaminants from around the

reservoir cap. Remove the cap from the hydraulic oil
reservoir.

2. Visually check the level of hydraulic oil. Hydraulic oil

must be at least 2" inches from top of the filler neck.
If the level cannot be determined visually, use a clean
tape measure to check the level. If the fluid is low,
add 20W50 motor oil. DO NOT overfill; (overfilling
the oil reservoir may cause oil seepage around the
cap area).

3. Clean the fill cap and install it onto the reservoir.

The hydraulic oil level should be checked after the first
10 hours of operation. Thereafter, check the oil every
200 hours of machine operation or monthly, whichever
occurs first.

Changing Hydraulic Oil

The hydraulic oil should be changed after every 500
hours or annually, whichever occurs first. The oil should
also be changed if the color of the fluid has become
black or milky. A black color and/or a rancid odor usually
indicates possible overheating of the oil, and a milky color
usually indicates water in the hydraulic oil.

2. Place a suitable container under the hydraulic oil

drain. Remove the fill cap from the reservoir.
Remove the drain cap from the T-Fitting located on
the hydraulic system filter head. (See Figure 14).
Allow the fluid to drain into the container and
properly discard it.

3. Reinstall the drain cap onto the T-Fitting and be sure

it is tight.

1. Park the mower on a level surface and stop the

engine.

Changing Hydraulic Oil Filter Element

The hydraulic oil filter should be changed after every 500
hours of operation or annually, whichever occurs first.

1. Remove the oil filter element  (Figure 15) and

properly discard it. Fill the new filter with clean oil
and install the filter. Hand tighten only.

                                  

-NOTE-

The hydraulic oil should be changed if you
notice the presence of water or a rancid odor
to the hydraulic oil.

-NOTE-

Before refilling the hydraulic oil reservoir the
hydraulic oil filter should be changed as well.
See instructions outlined below.

4. Fill the reservoir to 2" inches from the top of the filler

neck with 20W50 motor oil.

5. Replace the reservoir fill cap. Start the engine and

drive forward and backward for two minutes.
Check the oil level in the reservoir. If necessary, add
oil to the reservoir.
