Toro 74253 Operator's Manual page 31

Note: Using multi grade oils (5W-20, 10W-30, and
10W-40) will increase oil consumption. Check the oil
level more frequently when using them.
Checking the Engine Oil Level
Service Interval: Before each use or daily
Note: Check the oil when the engine is cold.
Contact with hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away the muffler and other hot surfaces.
1. Disengage the PTO, move the motion control levers
to the neutral locked position and set the parking
brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Release the seat and tip it forward.
4. Raise the radiator cover.
5. Clean around the oil dipstick (Figure 34) so dirt
cannot fall into engine.

6. Pull the oil dipstick and wipe the metal end clean
(Figure 34).
7. Slide the oil dipstick fully into the engine. Pull the
dipstick out and look at the metal end (Figure 34). If
oil level is low, slowly pour only enough oil into the
filler tube to raise the level to the full mark.
Important: Do not overfill the crankcase with
oil because the engine may be damaged. Do not
run engine with oil below the low mark because
the engine may be damaged.
Changing the Oil
Service Interval: After the first 8 hours
Every 100 hours (more often in dirty
or dusty conditions)
1. Start the engine and let it run five minutes. This
warms the oil so it drains better.
2. Park the machine so that the drain side is slightly
lower than the opposite side to assure the oil drains
completely.
3. Disengage the PTO and set the parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Slide the drain hose over the oil drain valve.
6. Place a pan below the drain hose. Rotate oil drain
valve to allow oil to drain (Figure 35).
7. When oil has drained completely, close the drain
valve.
8. Remove the drain hose (Figure 35).
Note: Dispose of the used oil at a recycling center.
