Contact your Authorized Service Dealer to adjust the controls of your machine.
Hydraulic System Maintenance
Hydraulic System Safety
-
Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor.
-
Ensure 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 pinhole 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.
Relieving Hydraulic Pressure
To relieve hydraulic pressure while the engine is on, disengage the auxiliary hydraulics and fully lower the loader arms.
To relieve the pressure while the engine is off, cycle the loader-arm/attachment-tilt lever between the forward positions to lower the loader arms. Turn the key switch to the RUN position and press the auxiliary-hydraulic switch back and forth.

Recommended hydraulic fluid: Toro PX Extended Life Hydraulic Fluid
Note: A machine using the recommended replacement fluid requires less frequent fluid and filter changes.
Alternative hydraulic fluids: If Toro PX Extended Life Hydraulic Fluid is not available, you may use another conventional, petroleum-based hydraulic fluid having specifications that fall within the listed range for all the following material properties and that it meets industry standards. Do not use synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.
Note: Toro does not assume responsibility for damage caused by improper substitutions, so use products only from reputable manufacturers who will stand behind their recommendation.
