Changing The Hydraulic Oil And Filter; Checking The Hydraulic Lines And Hoses; Adjusting The Brakes - Toro 04356 Operator's Manual

Changing the Hydraulic Oil and
Filter
Normally, change the hydraulic oil and filter after every
2000 operating hours. If the oil becomes contaminated,
contact your local Toro distributor because the system must
be flushed. Contaminated oil looks milky or black when
compared to clean oil.
1. Remove the drain plug from the reservoir (Fig. 44) and
let hydraulic oil flow into a drain pan. Reinstall and
tighten the plug when hydraulic oil stops draining.

2. Clean the area around the filter mounting area (Fig. 45).
Place a drain pan under the filter and remove the filter.

3. Fill the replacement filter with Mobil DTE 15M
hydraulic fluid. Lubricate the sealing gasket, and hand
turn the filter until the gasket contacts the filter head.
Tighten the filter 3/4 turn further. The filter should now
be sealed.
4. Fill the large hydraulic tank and small auxiliary tank
with approximately 8.5 gallons of hydraulic oil; refer to
Checking the Hydraulic System, page 15.
5. Start the machine and run it at idle for 3 to 5 minutes to
circulate the fluid and remove any air trapped in the
system. Stop the machine and recheck the fluid level.
Note: If the leak detector alarm sounds, turn the key Off
and wait a few minutes for the oil level to equalize in the
tanks. Recheck the fluid level and add oil, if required.
6. Dispose of the used oil properly.
Checking the Hydraulic Lines
and Hoses
Warning
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.
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.

Adjusting the Brakes

A brake adjustment rod is located on each side of the
machine so that the brakes can be equally adjusted. Adjust
the brakes as follows:
1. Transport the machine and depress the brake pedal; both
wheels should lock equally.
