Servicing The Engine Oil - Toro 74225 Operator's Manual

Installing the Filters
Important To prevent engine damage, always operate
the engine with both air filters and cover installed.
1. If installing new filters, check each filter for shipping
damage. Do not use a damaged filter.
2. If the safety filter is being replaced, carefully slide it
into the filter body (Fig. 35).
3. Carefully slide the primary filter over the safety filter
(Fig. 35). Ensure that it is fully seated by pushing on
the outer rim of the filter while installing it.
Important Do not press on the soft inside area of the
filter.
4. Install the air cleaner cover with the side indicated as
UP facing up and secure the latches (Fig. 35).

1. Disengage the power take off (PTO) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. Remove the key.
2. Clean around the oil dipstick (Fig. 36) so dirt cannot
fall into the filler hole and damage the engine.
3. Pull the oil dipstick out and wipe the metal end clean
(Fig. 36).
4. Slide the oil dipstick fully into the filler tube. Pull the
dipstick out and look at the metal end (Fig. 36). 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 Engine Oil
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. Disengage the power take off (PTO), set
the parking brake, and turn the ignition key to off.
Remove the key.
3. Place a pan below the oil drain. Remove the oil drain
plug (Fig. 37).
4. When oil has drained completely, install the drain
plug.
Note: Dispose of the used oil at a certified recycling
center.
