Servicing The Hydraulic System - Toro 74199 Operator's Manual

Servicing the Hydraulic
System
Check the hydraulic fluid level before engine is first
started.
Check the hydraulic fluid level after first 8 operating
hours.
Check the hydraulic fluid level 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.
Checking the Hydraulic Fluid, Cold
1. Position machine on a level surface and set the parking
brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 46).
3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir. (Fig. 46).
4. If there is no fluid, add fluid to the reservoir until it
reaches the cold level of the baffle.
5. Install cap on filler neck.
Checking the Hydraulic Fluid, Hot
Note: Check the hydraulic fluid after using the machine
for the first time. This allows any air to be purged from
the system.
1. Position machine on a level surface and set the parking
brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 46).
3. Remove cap from filler neck.
4. Recheck the fluid level while the fluid is warm. If
required, add fluid to the reservoir until it reaches the
hot level of the baffle.
Note: The fluid level should be to the top of the hot level
of the baffle, when the fluid is warm (Fig. 46).
5. Install cap on filler neck.

Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
If hydraulic fluid is injected into the skin it
must be surgically removed within a few hours
by a doctor familiar with this type of injury.
Gangrene may result if this is not done.
Keep 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.
Make sure all hydraulic fluid hoses and lines
are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
Replacing the Hydraulic Filter
Change the hydraulic filter:
After the first 8 operating hours.
After every 200 operating hours.
1. Position machine on a level surface, stop the engine,
and remove key from ignition switch.
Important
Do not substitute automotive oil filter or
severe hydraulic system damage may result.
2. Remove hydro cap and temporarily cover opening
with a plastic bag and rubber band to prevent all hydro
fluid from draining out.
3. Place drain pan under filter, remove the old filter and
wipe the filter adapter gasket surface clean (Fig. 47).
