Checking The Hydraulic Fluid; Greasing The Bearings - Toro 74225 Operator's Manual

3. Place air cleaner onto engine and align holes in air
cleaner bracket with holes in valve covers (Fig. 8).
4. Install valve cover screws into air cleaner bracket and
valve covers (Fig. 8).
5. Remove plastic plugs from air intake elbow on engine
and air cleaner hose (Fig. 8).
6. Install hose to air intake elbow on engine and air
cleaner. Tighten hose clamps to secure the hose
connections (Fig. 8).

Checking the Hydraulic Fluid

Check the hydraulic fluid level before engine is first
started.
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)
1. Position machine on a level surface, stop the engine
and set the parking brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 9).
3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir. (Fig. 9).

4. If there is no fluid, add fluid to reservoir
approximately a 1/4 in. (6 mm) below the top of
baffle.
5. Run the machine 15 minutes to allow any air to purge
out of the system and warm fluid.
6. Recheck level while fluid is warm. Add fluid to raise
level to top of the baffle, if required.
Note: Fluid level should be to the top of the baffle when
fluid is warm (Fig. 9).
7. 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.

Greasing the Bearings

Make sure cutting unit spindles are full of grease
before engine is first started.
