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.

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 (Figure 71), located on the left side
of the machine, is used to measure the forward
