2. Clean the area around the filter mounting area. Place a

drain pan under the filter and remove the filter

(Fig. 37 & 38).

3. Lubricate the new filter gasket and fill the filter with

hydraulic fluid.

4. Ensure that the filter mounting area is clean. Screw the

filter on until the gasket contacts the mounting plate;

then tighten the filter an additional 1/2 turn.

5. Start the engine and let it run for about two minutes to

purge air from the system. Stop the engine and check

for leaks.

Checking the Hydraulic Lines

and Hoses

Inspect the hydraulic lines and hoses daily for leaks, kinked

lines, loose mounting supports, wear, loose fittings, weather

deterioration, and chemical deterioration. Make all

necessary repairs before operating.

Hydraulic fluid escaping under pressure can

penetrate skin and cause injury.

• Make sure all hydraulic fluid hoses and lines are

in good condition and all hydraulic connections

and fittings are tight before applying pressure to

the hydraulic system.

• Keep your body and hands away from pin hole

leaks or nozzles that eject high pressure

hydraulic fluid.

• Use cardboard or paper to find hydraulic leaks.

• Safely relieve all pressure in the hydraulic

system before performing any work on the

hydraulic system.

• Seek immediate medical attention if fluid is

injected into skin.

Warning

Hydraulic System Test Ports

The test ports are used to test the pressure in the hydraulic

circuits. Contact your local Toro distributor for assistance.

Test Port “A” (Fig. 39), located on rear of filter manifold,

under right hand frame rail. Used to measure the traction

system charge pressure.
