Servicing The Engine Oil - Toro 74268 Operator's Manual

Servicing the Primary Filter
Blow compressed air from the inside to the outside of the
primary filter.
Important Do not exceed 100 psi and keep the hose at
least 2 inches from the filter. Replace air filters if they are
damaged or cannot be cleaned.
Servicing the Safety Filter
Do not clean the safety filter. Replace it after
600 operating hours.
Important
Never attempt to clean the safety filter. If
the safety filter is dirty, then the primary filter is damaged
and you should replace both filters.
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. 40).
3. Carefully slide the primary filter over the safety filter
(Fig. 40). 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. 40).
5. Install the front engine panel (Fig. 42).

Draining the Engine Oil
1. Start the engine and let it run for five minutes. This
warms the oil so it drains better.
2. Park the machine on a level surface.
3. Disengage the PTO, move the motion control levers to
the neutral locked position 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. Place a pan below the oil drain. Remove the drain plug
and let the oil drain completely (Fig. 41).
6. Remove the oil filler cap from the top of the engine
(Fig. 43). This will help the oil to drain.
