Checking The Hydraulic Fluid - Toro CT2240 Operator's Manual

1. Park the machine on a level surface.
2. Using a clean rag, clean the area around the fuel tank
cap.
3. Remove the cap from the fuel tank.
4. Fill the tank until the level is to the bottom of the filler
neck with diesel fuel.
5. Install the fuel tank cap tightly after filling the tank.
Note: If possible, fill the fuel tank after each use. This
will minimize possible buildup of condensation inside
the fuel tank.

Checking the Hydraulic Fluid

Service Interval: Before each use or daily—Check the
hydraulic-fluid level.
The reservoir is filled at the factory with approximately 32 L
(8.5 US gallons) of high-quality hydraulic fluid. The best time
to check the hydraulic fluid is when the fluid is cold. The
machine should be in its transport configuration. If the fluid
level is below the Add mark on the dipstick, add fluid to bring
the fluid level to the middle of the acceptable range. Do not
overfill the reservoir. If the fluid level is between the Full
and the Add marks, no fluid addition is required.
The recommended replacement fluid is:
Toro Premium All Season Hydraulic Fluid
(available in 19 L (5 US gallon) containers or 208 L (55 US
gallon) drums—see the parts documentation or your Toro
distributor for part numbers)
Alternative fluids: If the Toro fluid is not available, other
conventional, petroleum-based fluids may be used, provided
that they meet all of the following material properties and
industry specifications. Check with your fluid supplier to see
whether the fluid meets these specifications.
Note: Toro will not assume responsibility for damage
caused by improper substitutions, so use only products
from reputable manufacturers who will stand behind their
recommendation.

The proper hydraulic fluids must be specified for
mobile machinery (as opposed to industrial plant usage),
multiweight-type, with ZnDTP or ZDDP antiwear additive
package (not an ashless-type fluid).
Important: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system fluid is available in 20 ml (2/3 fl oz)
bottles. One bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500 from
your Authorized Toro Distributor.
Synthetic, Biodegradable Hydraulic Fluid
(available in 19 L (5 US gallon) containers or 208 L (55 US
gallon) drums—see the parts documentation or your Toro
distributor for part numbers)
This high-quality, synthetic, biodegradable fluid has been
tested and found compatible for this Toro model. Other
brands of synthetic fluid may have seal compatibility problems
and Toro cannot assume responsibility for unauthorized
substitutions.
Note: This synthetic fluid is not compatible with the
Toro Biodegradable Fluid previously sold. See your Toro
Distributor for more information.
Alternative fluids:
•
Mobil EAL Envirosyn H 46 (US)
•
Mobil EAL Hydraulic Oil 46 (international)
1. Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key from the ignition switch.
2. Check the sight level gauge on the side of the tank.
Note: The level needs to be at the upper mark.
3. If additional hydraulic fluid is needed, clean the area
around the filler neck and the cap of the hydraulic tank
(Figure 26) and remove the cap.
