Checking The Hydraulic Fluid; Tire Pressure - Toro 22303 Operator's Manual

Check Before Operating
9. Remove and store the cylinder locks (refer to
Using the Cylinder Locks, page 22), and lower
the loader arms.

Checking the Hydraulic Fluid

Check the hydraulic fluid level before the engine is
first started and after every 25 operating hours.
Hydraulic Tank Capacity: 17.25 gal. (67 l)
Use only Group 1 ISO type 46/68 anti–wear
hydraulic fluids, recommended for ambient
temperatures consistently below 100 F (38 C), such
as Toro Hy–Pro, Mobil Fluid 424, or other equivalent
fluid.
IMPORTANT: Use only the group 1 ISO type
46/68 anti–wear hydraulic fluids. Other fluids
could cause system damage.
1. Remove the attachment, if one is installed; refer
to Removing an Attachment, page 24.
2. Park the traction unit on a level surface, raise the
loader arms, and install the cylinder locks; refer
to Using the Cylinder Locks, page 22.
3. Stop the engine and remove the key.
4. Remove the front access cover, refer to
Removing the Front Access Cover, page 27.
5. Clean the area around the filler neck of the
hydraulic tank (Fig. 9).

Tire pressure

Maintain the air pressure in the tires as specified.
Check the tires when they are cold to get the most
accurate reading.
Pressure: 15–20 psi (103–138 kPa)
Note: Use a lower tire pressure (15 psi/
103 kPa) when operating in sandy soil
conditions to provide better traction in
the loose soil.
