Hydraulic System Maintenance; Checking The Hydraulic Fluid - Toro 74237 Operator's Manual

A very small amount of mercury is contained in
a hermetically sealed body. The steel switch is
then potted in a hard epoxy in a plastic case. It is
unlikely that the mercury will ever escape from the
enclosure. These high performance and reliable
inexpensive switches are recyclable.
Mercury is an important and beneficial compound
but requires special care in handling and disposal.
When used and managed properly, mercury is
not a threat to people or the environment. This
information is presented to users so that they are
aware that these switches contain mercury and will
apply sound disposal practices when these devices
reach their normal end of life or are damaged.
Disposing the Mercury Tilt Switch
Several states have passed laws concerning the
disposal of devices containing mercury. In all the
remaining states it is advisable to follow similar
procedures. The laws state that these sealed
devices contain mercury and should not be placed
in the garbage until the mercury is removed and
reused, recycled or otherwise managed to insure
that it does not become part of solid waste or
waters. Management and disposal practices must
be within relevant federal, state or local laws.
Return the switch to your Toro dealer if it is faulty
and is being replaced or if the unit containing
the switch is no longer operating and is being
scrapped. If the switch is damaged or broken open
use extreme caution in handling. Call your local
waste management authority or Toro Customer
Service for instructions.
The mercury contained in the tilt switch
is poisonous and exposure to mercury can
cause severe illness.
• Never attempt to open or repair the tilt
switch.
• Avoid contact with the mercury.
Hydraulic System
Maintenance
Checking the Hydraulic
Fluid
Check the hydraulic fluid level:
• Before the engine is first started.
• After the first 8 operating hours.
• After every 25 operating hours.
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important: Use oil specified or equivalent.
Other fluids could cause system damage.
Hydraulic System Oil Capacity: 67 oz. (2.0 l)
Note: There are two ways of checking the
hydraulic oil. One is when the oil is warm and one
is when the oil is cold. The baffle inside the tank
has two levels depending if the oil is warm or cold.
1. Position the machine on a level surface and set
the parking brake.
2. Clean the area around filler neck of hydraulic
tank (Figure 55).

3. Remove the cap from the filler neck. Look
inside to check if there is fluid in the reservoir
(Figure 55).
4. If there is no fluid, add fluid to the reservoir
until it reaches the cold level of the baffle.
5. Run the machine at low idle for 15 minutes to
allow any air to purge out of the system and
warm the fluid. Refer to Starting and Stopping
the Engine in Operation, page 14.
