Servicing The Engine Oil - Toro 74805 Operator's Manual

Cleaning the Primary Filter
Blow compressed air from the inside to the outside of the
primary filter.
Important
Do not exceed 685.5 kPa (100 psi) and keep
the hose at least 5cm (2 in.) from the filter.
Installing the Filters
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. 55).
3. Carefully slide the primary filter over the safety filter
(Fig. 55). 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. 55).

Checking the Engine Oil Level
1. Park the machine on a level surface, disengage the
power take off (PTO) and turn the ignition key to off.
Remove the key.
2. Clean around the oil dipstick (Fig. 56) so dirt cannot
fall into the filler hole and damage the engine.
3. Pull the oil dipstick and wipe the metal end clean
(Fig. 56).
4. Slide the oil dipstick fully into the filler tube (Fig. 56).
Pull the dipstick out and look at the metal end. 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.
