3.
Lubricate new filter gasket and fill the filter with
hydraulic fluid.
4.
Assure filter mounting area is clean. Screw filter on
until gasket contacts mounting plate. Then tighten filter
one–half turn.
5.
Start engine and let run for about two minutes to purge
air from the system. Stop the engine and check for
leaks.
Checking Hydraulic Lines And
Hoses
Daily, check hydraulic lines and hoses 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.
•
If hydraulic fluid is injected into the skin it must
be surgically removed within a few hours by a
doctor familiar with this type of injury.
Gangrene may result if this is not done.
•
Keep 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.
•
Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
hydraulic system.
Warning
Using the 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 #1 is used to assist in trouble shooting the
hydraulic circuit for the front cutting units and lift
cylinders.

2.
Test Port #2 is used to assist in trouble shooting the
hydraulic circuit for the rear cutting units.
3.
Test Port #3 is located on the rear of the hydrostatic
transmission and is used to measure the charge pressure
of the transmission.
4.
Test Port #4 is located on the rear of the lift block and is
used to assist in trouble shooting the hydraulic lift
circuit.
Adjusting Traction Drive For
Neutral
The machine must not creep when traction pedal is
released. If it does creep, an adjustment is required.
1.
Park machine on a level surface, shut engine off and
lower cutting units to the floor. Depress only the right
brake pedal and engage the parking brake.
2.
Jack up left side of machine until front tire is off the
shop floor. Support machine with jack stands to prevent
it from falling accidentally.
Note:
On 4 wheel drive models, left rear tire must also be
off the shop floor or 4 wheel drive driveshaft must be
removed.
3.
Under right side of machine, loosen locknut on traction
adjustment cam.
