1. Dipstick
3. Insert the dipstick fully into the dipstick tube, then
remove the dipstick (Figure 21).
4. Read the oil level on the dipstick.
•
If the oil level is too low, slowly pour a small
amount of the specified oil into the oil-filler neck
(Figure 44), wait 3 minutes; refer to step 1 in Filling
the Engine with Oil (page 40).
•
If the oil level is too high, drain the excess oil until
you obtain the correct oil level on the dipstick;
refer to Draining the Engine Oil (page 39).
5. Repeat steps 2 through 4 until the oil level is correct.
6. Install the dipstick and oil-fill cap securely.
7. Install the right-side panel; refer to Installing the Side
Panels (page 37).
Checking the Hydraulic Fluid
Level
Service Interval: Before each use or daily
Use Toro Premium All-season Hydraulic Fluid (available
in 5-gallon pails or 55-gallon drums. See the parts catalog or
an Authorized Toro Service Dealer for part numbers).
If Toro hydraulic fluid is not available, you may use an
equivalent hydraulic fluid, provided that it meets all the
following material properties and industry specifications. Do
not use a synthetic hydraulic fluid. Consult with your
lubricant distributor to identify a satisfactory product.

Industry Specifications:
Note: Many brands of hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for the
hydraulic system oil is available in 20 ml (0.68 oz) bottles.
One bottle is sufficient for 15.1 to 22.7 L (4.0 to 6.0 US gal)
of hydraulic oil. Order part no. 44-2500 from an Authorized
Toro Service Dealer.
1. Park the machine on a level surface, and put all the
attachments in the transport position.
2. Stop the engine, set the parking brake, and remove the
ignition key.
3. Check the hydraulic fluid level in the sight gauge
located at the side of the hydraulic reservoir (Figure 22).
1. Fill level (midpoint)
2. Sight gauge
Note: The hydraulic fluid level should be between the
Add and Full marks on the sight gauge.
4. If the hydraulic fluid level is below the Add mark,
remove the fill cap/breather (Figure 22), add the
specified hydraulic fluid to raise the fluid level up to the
Full mark, and install the fill cap/breather.
