Checking The Hydraulic Lines And Hoses; Charging The Hydraulic System - Toro Sand Pro 3040 Operator's Manual

Note: If the machine is equipped with a remote
hydraulics kit, the suction hose can be removed from
the pump to drain the hydraulic fluid.
5. Remove the filter when the fluid flow slows.
6. Lubricate the sealing gasket on the replacement filter
with hydraulic fluid and turn it on by hand until the
gasket contacts the filter head. Then tighten it 3/4
turn further.
Note: The filter should now be sealed.
7. Fill the hydraulic tank with hydraulic fluid until the level
is up to the necked-down area of the dipstick. Do not
overfill the tank. Refer to
Hydraulic Fluid (page
8. Start and run the engine. Operate the lift cylinder until
it extends and retracts and forward and reverse wheel
motion is achieved.
9. Stop the engine and check the fluid level in the
reservoir; add fluid if necessary.
10. Check all connections for leaks.
11. Install the center shroud.
12. Dispose of the used oil properly.
Checking the Hydraulic Lines
and Hoses
Service Interval: Before each use or daily
Check 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.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure that 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.

Charging the Hydraulic
System
Whenever a hydraulic component is repaired or replaced,
change the hydraulic filter and charge the hydraulic system.
Make sure that the hydraulic reservoir and the filter are filled
with fluid at all times when charging the hydraulic system.
1. Park the machine on a level surface and turn the engine
off.
2. Loosen the 2 screws securing the center shroud to the
machine and remove the shroud
1. Center shroud
3. Raise the front wheel and 1 of the rear wheels off the
floor and place support blocks under the frame.
WARNING
The front wheel and 1 rear wheel must be
raised off the ground, or else the machine will
move during the adjustment. This could cause
the machine to fall and injure someone under
the machine.
Make sure that the machine is adequately
supported, with the front wheel and 1 rear
wheel raised off the ground.
4. Start the engine and set the throttle to allow the engine
to run at approximately 1800 rpm.
5. Actuate the lift-valve lever until the lift-cylinder rod
moves in and out several times. If the cylinder rod does
not move after 10 to 15 seconds or the pump emits
abnormal sounds, shut the engine off immediately
and determine the cause or problem. Inspect for the
following:
•
Loose filter or suction lines
•
Loose or faulty coupler on the pump
•
Blocked suction line
