Testing the Hydraulic
Pressure
1.
Start the engine and move the machine to a
level, open area.
Important:
The area to the rear and around
the machine must be clear.
2.
Ensure that the parking brake switch is on the
E
position.
NGAGED
3.
Set the engine speed to idle.
4.
Run the engine to warm the coolant to 70 to
75°C (160 to 170 °F).
5.
Sitting in the seat with the park brake engaged,
gradually press the reverse traction pedal.
Important:
If the reverse pedal is pressed
gradually and gently, the park brake should
keep the machine from moving backward.
6.
Observe the pressure gauge for stable
measurement of the maximum hydraulic
pressure while pressing the reverse pedal.
7.
Record the maximum hydraulic-pressure
measurement here:
8.
Compare the maximum hydraulic pressure that
you measured with the normal pressure range in
the Hydraulic-Pressure Table.

Important:
If the hydraulic pressure
measurements are lower than or higher than
the normal pressure range, contact Toro
customer care.

Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operator's position.
