Check The Engine Oil Level; Check For Debris - Toro Wheel Horse 520xi Operator's Manual

Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline.
Filling the Fuel Tank
1. Park the machine on a level surface, disengage the
PTO, set the parking brake, lower the attachment lift,
stop the engine, and remove the ignition key.
Note: When filling the tank, make sure that the machine
is on a level surface so that adequate air space is allowed.
2. Clean around the fuel tank cap and remove the cap.
3. Add fuel until the fuel level is 1/4 to 1/2 in. (6 mm to
13 mm) below the bottom of the filler neck.
This space in the tank allows for expansion of the fuel.
Do not fill the fuel tank completely.
4. Install the fuel tank cap securely.
5. Wipe up any gasoline that may have spilled.

Check the Engine Oil Level

1. Park the machine on a level surface, disengage the
PTO, set the parking brake, lower the attachment lift,
stop the engine, and remove the ignition key.
2. Open the hood.
3. Clean around the oil dipstick (Fig. 5) so dirt cannot
fall into the dipstick tube and damage the engine.

If the oil level is low (near the L mark), add oil; refer
to Engine Oil, page 22.
Important
Do not overfill the crankcase with oil
because this may result in engine damage.

Check for Debris

Important
Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or cooling
shrouds removed, will result in engine damage from
overheating.
1. Park the machine on a level surface, disengage the
PTO, set the parking brake, lower the attachment lift,
stop the engine, and remove the ignition key.
2. Check for debris on the air-intake screens (Fig. 7).
