Hydraulic System Test Ports - Toro 03806 Operator's Manual

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.
• Get immediate medical help if fluid is
injected into skin.

Hydraulic System Test Ports

The test ports are used to test pressure in the hydraulic
circuits. Contact your local Toro distributor for
assistance.
1. Test Port A (Figure 80 and Figure 81) is used to

4. Test Port D is located on the bottom of the
hydrostatic transmission (Figure 83) and is used to
measure the charge pressure of the transmission.
5. Test Port E is used to measure traction forward
pressure (Figure 83).
6. Test Port F is used to measure traction reverse
pressure (Figure 83).
7. Test Port G is used to measure steering circuit
pressure (Figure 83).
