Servicing The Engine Oil - Toro 74401 Operator's Manual

Servicing the Engine Oil

Change the oil after the first 8 operating hours and every
100 operating hours thereafter.
Oil Type: Detergent oil (API service SC, SD, SE, SF, SG,
or SH)
Crankcase Capacity: w/filter, 1.6 qt. (1.5 l)
Viscosity: See the table below.
USE THESE SAE VISCOSITY OILS
Checking the Oil Level
1. Park the machine on a level surface, disengage the PTO,
stop the engine, and remove the key.
2. Clean around the oil dipstick (Fig. 15) so that dirt
cannot fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 15).
4. Slide the oil dipstick fully into the filler tube, but do not
thread it onto the tube (Fig. 15). Pull the dipstick out
and look at the metal end. If the oil level is low, slowly
pour only enough oil into the filler tube to raise the
level to the "FULL" mark on the dipstick.
Important
Do not overfill the crankcase with oil
because the engine may be damaged.

Changing and Draining the Oil
1. Start the engine and let it run for five minutes. This
warms the oil so that it drains better.
2. Park the machine so that the drain side is slightly lower
than the opposite side to ensure that the oil drains
completely. Then disengage the PTO, set the parking
brake, stop the engine, and remove the key.
3. Place a pan below the oil drain. Remove the oil drain
cap (Fig. 16).
4. When the oil has drained completely, install the drain
cap.
Note: Dispose of the used oil at a certified recycling center.

5. Clean around the oil dipstick and unscrew the cap
(Fig. 15).
6. Slowly pour approximately 80% of the specified
amount of oil, page 20, into the filler tube (Fig. 15).
Check the oil level; refer to Checking the Oil Level,
page 20. Slowly add additional oil to bring the level to
the "FULL" mark on the dipstick.
